If you’re looking for a dessert that balances indulgence with freshness, the blueberry chocolate tart checks every box. It’s rich but not overwhelming, fruity but not too sweet, and it always looks more impressive than the effort it takes to make. Whether you’re baking for a dinner party, a brunch gathering, or just treating yourself, this tart delivers a deliciously satisfying experience.
At the heart of the tart is a crisp, buttery crust. It’s the perfect base for the smooth chocolate ganache that follows, a filling made from good-quality dark chocolate and cream. The ganache is glossy, velvety, and melts in your mouth with every bite. Once the chocolate sets, it’s topped with a layer of fresh blueberries. The contrast between the rich chocolate and the tangy berries creates a flavor profile that’s both complex and refreshing.
You can play with the layers to suit your style. Some versions fold the berries into the ganache, allowing them to soften slightly and deepen in flavor. Others pile the berries on top for a burst of color and a bright, juicy texture. You might even drizzle melted chocolate or a light fruit glaze over the top for a polished finish.
This tart doesn’t demand special equipment or complicated techniques. A tart pan with a removable bottom helps with presentation, but even a basic pie dish will do. It can be made ahead of time and chilled until ready to serve, which makes it perfect for entertaining.
Serve the tart on its own or with a scoop of vanilla ice cream, a spoonful of whipped cream, or a few mint leaves for contrast. However you style it, the result is elegant, delicious, and memorable.
The blueberry chocolate tart is proof that simple ingredients can create something extraordinary when paired thoughtfully. It’s a dessert that’s as enjoyable to make as it is to eat.
Ingredients
- 1 1/2 cup all-purpose flour
- 1/3 cup cocoa powder unsweetened
- 1/2 cup powdered sugar
- 1/2 tsp salt
- 3/4 cup unsalted butter cold and cut into cubes
- 1/4 cup whole milk
- 1/2 tsp vanilla extract
- 1 1/2 cup blueberries fresh
- 1/4 cup granulated sugar
- 2 tbsp cornstarch
- 1/4 cup water
- 1 tbsp lemon juice
- 1/2 cup semisweet chocolate chips
- 1/2 cup heavy cream
Instructions
- In a food processor, combine the flour, cocoa powder, powdered sugar, and salt. Pulse a few times to combine.
- Add the cold butter cubes and pulse until the mixture resembles coarse crumbs.
- In a small bowl, whisk together the milk and vanilla extract. Slowly pour the mixture into the food processor while pulsing, until a dough forms.
- Transfer the dough to a lightly floured surface and knead it a few times to bring it together. Shape the dough into a disc and wrap it in plastic wrap. Refrigerate for at least 30 minutes.
- Preheat the oven to 375°F (190°C).
- Roll out the chilled dough on a lightly floured surface to fit a tart pan. Press the dough into the pan and trim any excess.
- In a medium saucepan, combine the blueberries, granulated sugar, cornstarch, water, and lemon juice. Cook over medium heat, stirring frequently, until the mixture thickens and the blueberries release their juices. Remove from heat and let cool slightly.
- Pour the blueberry mixture into the tart shell.
- In a small microwave-safe bowl, heat the chocolate chips and heavy cream in 30-second intervals until the chocolate is melted. Stir until smooth.
- Pour the chocolate mixture over the blueberry filling.
- Bake the tart in the preheated oven for 20 minutes, or until the crust is golden and the chocolate filling is set.
- Remove from the oven and let cool before serving.

Delicious…
Yum! Who knew blueberries and chocolate would go so well together? Love it!
Why bother with all these ingredients? Just buy a store-bought tart. This is way too complicated!
Yay! Finally tried this recipe and it turned out great! I just used frozen blueberries. Still yum!
Is blueberriez even good with chocolat? I thought it would be weird but it’s actually nice! I will make again.
This was the best dessert I’ve ever made! Super easy and sooo delicious!
Too many ingredients, I like simple recipes.
What is cornstarch for? Can’t we just use flour? I’m not good with these fancy things
This tart is a perfect blend of flavors! The blueberries with chocolate is just divine. Will definitely make it again!
So good!! Blueberry and chocolate??? Yes, please! It was a hit with the kids too. 🍫💙
This sounds amazing! Blueberries and chocolate are like the perfect duo! I’m gonna make this for my kids too! 🍫💙
I dunno, blueberries and chocolate? Seems weird to me. Aren’t those flavors kinda clash? 😕
I forgot to add lemon juice. It was still good but any ideas how to fix it next time?
This is a lot of steps. I might just buy a tart from the store instead.
I totally get it! Sometimes it feels like too much. But homemade is way better! 💖
Buying from the store is easier, but this tart sounds delicious! Maybe just try it once? 🤔
Can I substitute the semisweet chocolate with milk chocolate? Asking for a friend.
omg!!! Yummmmyyy! 😍 5 stars!!!
This is lit! I made it for my friend’s birthday and everyone loved it. Gonna be my go-to dessert!
Had a great time making this with my baking group! Tastes even better than it looks.
Sounds delicious! I’m gonna try this with my friends too. Thanks for sharing!
Hmm, looks good but isn’t chocolate and blueberries a weird combo? Not sure if I’ll make this.
It’s alright. Just okay. Nothing special in my opinion.
I think it’s special! The combo of chocolate and blueberries is to die for! Just have to tweak the recipe a bit.
Wow, I didn’t expect it to look so fancy! I made it for a party and everyone loved it. Very impressive! 👍
That sounds amazing! I’m definitely trying this for my next gathering. Thanks for sharing! 😊
This tart was amazing! I really loved the combo of blueberries and chocolate. Will def make again!
I followed the recipe exactly, but my tart turned out super soggy. What did I do wrong?
Maybe you didn’t cook the blueberries long enough? They can make it soggy if too much juice is left.
Soggy? Ugh, that’s the worst. Did you let it cool completely before taking it out of the pan? That can help!
Are we supposed to cook the blueberries? Mine just popped all over the place!
Yeah, you’re supposed to heat them a bit to thicken the filling. Otherwise, they go everywhere! Happened to me too the first time.
No way! I thought you just toss them in raw! Next time I’ll try cooking them. Hope mine doesn’t pop like that!
My kids didn’t like it that much, too much chocolate I guess?
Not sure how they don’t like it, chocolate is the best! More for me! 😋
Maybe try less chocolate next time? Kids can be picky with flavors.
A bit too sweet for my taste. Might reduce the sugar next time.
Absolutely fabulous! I used frozen blueberries and it turned out fine.
My crust didn’t turn out right. It was all crumbly. Any tips on how to fix that?
I forgot the lemon juice and it still turned out great! Baking magic!
It was too sweet for my taste. I think next time I’ll use less sugar. The crust fell apart though.
I totally get what you mean! I found it a bit sweet too. Maybe try dark chocolate next time; it balances it out better. But the crust can be tricky sometimes. Hope it works better next time!
This tart reminds me of the time I made a mistake in the kitchen. 😂 But I love it!
Did I do something wrong? The filling didn’t set right. It was runny… like soupy chocolate blueberry mess. 😩
It happens to the best of us! Maybe you didn’t let it cool enough before slicing? I’d still eat a messy tart tho! 😅
Oh no! I’m sorry to hear that. Sometimes the filling doesn’t set if the mixtures aren’t cooked long enough or if there’s too much liquid. Try cooking the blueberries longer next time! 🤞
This tart is a great balance of chocolatey and fruity! Yum!
Wow, really impressed with this recipe! It turned out beautiful and delicious! ❤️
This recipe looks too complicated. I’m just gonna buy a tart instead.
Not bad, but I thought it would be more chocolaty. The tart was kinda soggy too. 😟
I think I mixed up the temps or something, crust burnt bad! Check your oven guys!
Maybe just watch it closely next time? Burnt crust is the worst! But I’m sure it still tasted good with the chocolate and blueberries!
Oh no! That happened to me once too! I think it could be the oven temperature being off. Always good to have an oven thermometer just in case!
Made this for a potluck and everyone went bananas over it! Thanks!
I feel like the chocolate kinda overpowers the blueberries. Maybe less chocolate next time?
Not sure why people rave about this. It didn’t taste like much to me. Kinda bland.
I disagree! I thought the flavor was delish. The combination of chocolate and blueberries is so good! 😋
Super easy recipe! just tried it and turned out perfect, thanks!
So delicious! Made it for a dinner party and everyone loved it! Will definitely make again.
I’m so happy to hear that! This tart was a hit at my last gathering too! Your guests must have loved it!
But can it really be that good? I mean, blueberries and chocolate? Seems kinda weird to me.
Super rich but on the heavier side. Maybe I should’ve cut the chocolate part a bit? Still tasty tho.
Honestly, too rich for my taste. I think there should be more blueberries than chocolate! 😅
Cutting the chocolate might help! I usually use less chocolate for a lighter dessert too, but I love the richness of this one.
I followed the instructions to a T, but my crust didn’t turn out right. Any tips?
Sorry to hear that! Maybe the butter was too warm? Make sure to chill it well before using. Good luck!
Really good! But why is there so much butter? Seems unhealthy 🤔.
Perfect dessert for summer! 🍇🍫 Love the freshness of blueberries with chocolate!
I don’t know about mixing blueberries and chocolate. Seems kinda weird to me. Wasn’t really for my taste.
I dunno about mixing chocolate and blueberries… sounds weird.
I thought the same, but chocolate and blueberries is actually really tasty together! You should try it!
My tart exploded in the oven… should I really have used a smaller pan? 🤦♀️
Easy recipe, I made it for a dinner party and everyone loved it! Thanks for sharing.
Could use less butter. It was too rich for my taste. Not my fav dessert. 😕
This tart is absolutely divine! The combo of blueberries and chocolate is perfect. My family couldn’t get enough of it!
Blueberries and chocolate? Sounds weird. Are you sure this tastes good together? I might just stick to regular fruit tarts.
I totally agree! I made this for my kids and they loved it. Even my picky eater went for seconds!
Not sure why you need cornstarch… isn’t that for thickening? Maybe just cook it longer?
The chocolate and blueberries combo is surprisingly good! Found my new favorite dessert!
This tart looks amazing! I can’t wait to try it out this weekend.
I can’t bake to save my life but I might give this a shot.
Don’t give up! Baking is easier than it looks. Just follow the steps and you’ll do great!
Blueberries are healthy, right? So this should be good for me! lol
Yummm, tart is yumm! My mom loved it, she said it was super fancy! 👏
This chocolate tart is to die for! The blueberries and chocolate combo is genius. 5 stars!
Sounds good but chocolate and fruit? Is that even a thing? I always thought they shouldn’t mix.
I totally agree! This tart is amazing! I made it last week and my friends couldn’t get enough!
Easy to follow, but I replaced the blueberries with raspberries ’cause I had some in the fridge. Still turned out great!
I dunno, it was kinda hard to make. Maybe I messed up the crust? My kids said it was too chocolaty.
Easy to make and super delicious! My family loved it, will definitely make again.
Not sure about mixing blueberries with chocolate. It seemed off to me. I expected it to be sweeter.
Tried this recipe but it didn’t turn out as expected. My chocolate melted too much and the tart was kinda soggy. Not the best… 😕
I forgot the lemon juice and it still tasted good. Maybe not as bright, but still yum! Definitely making it again.
Glad to hear you enjoyed it! Lemon juice does add a nice zing, but it sounds like you made it work without it. Yum!
Um, I don’t know about this one. Blueberry and chocolate? Feels like a weird combo. But hey, I’m willing to try anything once. 😂
I know it sounds odd but trust me, blueberry and chocolate are actually great together! You might be surprised. 😊
Too much work for a tart. Could’ve just bought it at the store for half the time! ⏳ Not impressed.
This tart is amazing! The combination of blueberry and chocolate is to die for. I can’t believe how easy it was to make! 😍
SO GOOD! Who knew blueberries and chocolate would go together? My kids devoured it! 🎉
Yum! Will my waistline survive this? Haha, but seriously, it’s delish! Making it for a dinner party!
Not gonna lie, 20 minutes at 375 seems short for the crust to fully bake—mine was a bit soft in the center.
I accidentally used frozen blueberries and the filling took forever to thicken. Still tasty though—just messy. Might be my fault.
I didn’t have cornstarch, so I used flour instead. It didn’t thicken up right. Lesson learned!
5 stars! Just made it for a dinner party and it was a hit! Everyone kept asking for the recipe. 😍
I was skeptical about this recipe at first. Chocolate and berries? Seemed odd. But wow, it was a good surprise!
Wow, this looks dangerously good. The cocoa crust + blueberry + chocolate combo is such a cheat code. I’d probably add a pinch of espresso powder too for extra depth.
Honestly tastes like a fancy store-bought tart. I got compliments from people who “don’t even like desserts,” lol. 10/10 would make again.
Followed the recipe pretty much exactly and it came out pretty. Flavor is rich but not overly sweet. Next time I might add a pinch more salt because I like that contrast, but overall great.
Glad it came out rich but not too sweet—your salt tweak makes sense! I always find cocoa can mute flavors a bit.
I like the concept, but 20 minutes at 375 for the chocolate topping felt a little short to me. Next time I might bake 5 more mins so it sets firmer.
Good call—20 min at 375°F can definitely be a bit optimistic for a thicker chocolate layer. I’d also try chilling it after baking so the topping firms up more.
I gave this 2 stars because the oven timing is off and my tart broke when I tried to slice it. Also I burned the bottom a little. Flavor saved it. Next time I’ll bake longer and let it cool completely.
Ugh that sucks—thanks for being honest. I’ve had tarts crack when I slice too soon too. Did you let it cool longer than the recipe says? Mine always needs way more time.
20 min at 375 seems short for a tart shell with cocoa. I’d try 25–30 and keep an eye on the bottom so it doesn’t burn. Also, cutting while it’s warm will definitely break it.
Yum! This tart is so good! I shared it with my family and they loved it too. Easy to follow, thanks!
10/10. super easy.
This sounds dangerously good. Cocoa crust + blueberries + chocolate? I can already taste it. Did anyone try it with frozen berries?
This looks dangerously delicious. The cocoa crust + blueberry + chocolate combo is like dessert perfection. I might cut the sugar just a bit, but overall, I’m in.
Could you substitute strawberries instead? Not a fan of blueberries myself. 🤷♂️
The crust came out crumbly for me until I pressed it really firmly into the pan. Also I kneaded a bit more than the recipe said and that helped.
This tart is divine! The chocolate and blueberries are such a perfect match. I’ll definitely make it again! 🫐🍫
Mine cracked when I rolled it out. I think I didn’t chill long enough (I only did 15 min). Flavor is great, but texture needs more patience.
Blueberries + chocolate is my weakness. I love the lemon juice in the filling too—it keeps it from tasting flat. Will make again for sure.
Made it last weekend and it came out pretty solid. I used a bit more lemon juice because my berries were kinda tart—no regrets.
Blueberries + chocolate + lemon juice?? Sounds like flavor overload but in the best way. The lemon actually makes it taste brighter, not weird.
Right?? Lemon + berries is such a “bright” combo. I think the chocolate makes it richer without tasting like a weird citrus dessert.
I’m skeptical only because blueberry + chocolate + lemon juice sounds like it could get sour… but if there’s enough sugar and the crust is cocoa, it might balance out. Anyone tried it yet?
Not gonna lie, 20 minutes at 375 felt short. My chocolate layer was set but the crust was a little soft. Maybe my oven runs cool. Taste was amazing though.
I failed miserably. My dough turned out a sticky mess. What did I do wrong? 🤔
Not bad, but the instructions are a little all over the place. Like, step 11 says bake 20 minutes, then step 12 says cool—how long though? Still tasted good, just unclear.
Honestly I just serve it right away lol. The chocolate sets while it cools in the pan. But yeah it could say how long.
Yeah I get what you mean—step 12 is super vague. I usually let it cool about 20-30 minutes at room temp, then slice once it’s set.
The instructions are pretty clear. I just wish it said what size tart pan (like 9 inch?) because my bake time ended up slightly different.
The math isn’t mathing for me—3/4 cup butter for a crust that uses 1.5 cups flour feels like a lot? I thought it would be greasy but it wasn’t. Still, I reduced butter next time and it was even better for my taste.
Totally get that—3/4 cup butter for 1.5 cups flour does sound like a lot on paper. I think the food processor crumbs + chilling helps it bake up crisp instead of greasy, but reducing butter is such an easy tweak if that’s your preference.
Not gonna lie, the combination is weird to me—blueberry and chocolate always feels like a dessert committee meeting. But I’ll try it once.
This is basically dessert chaos. Chocolate on blueberries on chocolate-ish crust. I mean… I can’t say no, but my taste buds are tired already.
Wow. The crust is so chocolatey and the blueberry layer tastes fresh even though it’s baked. Definitely a keeper.
I used frozen blueberries and the filling got watery before thickening. Next time I’ll thaw and drain them. Still tasty, but the texture wasn’t as great.
I used frozen blueberries and had to add like 2 extra tbsp cornstarch because it stayed thin at first. Once thickened, it was great. Worth adjusting if you don’t have fresh.
Good to know! I’m always dealing with frozen berries being more watery—2 tbsp extra cornstarch sounds like a solid fix.
I was skeptical about cornstarch thickening with just water + lemon, but wow it worked. The blueberries cooked up nice and glossy. Crust stayed crisp-ish even after chilling.
I think 1/2 cup powdered sugar in the crust is too much with already sweet fillings. Might be better with less sugar or a less chocolatey topping.
The dough step is confusing me a bit—when you say “knead it a few times,” mine just sort of crumbled. I pressed it into the tart pan instead of kneading and it still turned out fine, so maybe no big deal.
20 minutes at 375°F seems short for a tart shell—won’t it stay a bit soft? I’m nervous the crust won’t fully set. Maybe I’m just impatient.
I get the worry, but 20 min at 375°F is usually enough since the crust is already chilled and baked until it turns golden. The chocolate layer also sets as it cools—so a little softness right after baking is normal.
I tried it but my tart shell shrank a ton. I think I didn’t chill long enough. Still tasted great, just looked sad lol.
Aw nooo 😭 but yeah, chilling really is the make-or-break for tart dough. Next time try 45–60 min (or even 15 min in the freezer right before rolling). Also make sure it’s chilled before it hits the oven.
Mine shrank once too—turns out I rolled it a bit too thin. I’d aim for like 1/4 inch and don’t stretch it when pressing into the pan. Still, if it tasted great, you’re doing something right!
I used frozen blueberries and cooked them longer; filling was thinner at first but it thickened up. Good adaptation, would recommend.
Not gonna lie, I was skeptical about putting heavy cream with chocolate in the microwave… but it melted smooth. I’ll do this again.
The blueberry filling tasted bright, but my cornstarch got a bit lumpy even though I stirred. Maybe I should whisk cornstarch with water more thoroughly next time.
Meh… the whole thing is kind of heavy. The chocolate layer tastes good, but after a couple bites it gets too rich for me.
This is dangerously good. The cocoa crust + blueberry jammy filling is a perfect combo, and the chocolate layer makes it feel fancy. I did have to cool the filling longer so it wouldn’t seep as much—still worth it!
This looks insanely good—blueberry + chocolate is such a winning combo. I might add a pinch of cinnamon to the crust just for warmth.
Not sure about mixing the chocolate with heavy cream then microwave—seems too risky? I’d rather use a double boiler, but maybe it works fine.
Microwave ganache can split if you overheat it, so I’d be careful. If you try it, keep it low and stir a lot. Double boiler is definitely the “no drama” method though.
I get why that sounds risky, but 30-second intervals are pretty safe. I do the same thing and it usually comes out smooth—just stir between bursts so it doesn’t scorch.
The crust flavor is super chocolatey and the crumbly texture is on point. I was worried about kneading, but it worked out fine.
Yes!! I get the same super chocolatey crust vibe—this tart is dangerous 😄 And kneading being easy is a relief, because I always overthink dough stuff.
Mine came out good but I didn’t knead at all, I just pressed it together—maybe that’s why my crust was a bit more tough. Still tasted great though. Did you chill longer than 30 min?
This looks insanely good—cocoa crust + blueberry jammy layer + chocolate ganache is basically my dream dessert. Gonna try it this weekend!
The instructions are clear, but I feel like 20 minutes might not be enough for the chocolate to fully set—mine was a little soft in the middle. Still tasty though.
Good call—mine also needed a few extra minutes. I baked closer to 25–28 and the center firms up better. 20 min works only if your tart pan is thinner/heats evenly.
I think 20 min is totally fine. If it’s soft, maybe you didn’t cool it long enough—chocolate sets as it cools, not just in the oven. Also, different chocolate chips melt different.
The ingredient list says 1/4 cup granulated sugar plus powdered sugar in the crust—kinda sweet. I might cut sugar by 25% next time.
My tart shell shrank a bit after baking. I think I rolled it too thin. Next time I’ll refrigerate longer and avoid overworking the dough.
Kids loved it. I served it slightly warm and the chocolate was super gooey. The only complaint was “more chocolate please,” lol.
Aww love that “more chocolate please” is the only complaint 😄 I’m with you—those gooey chocolate layers are the best part. Did you end up baking it the full 20 minutes, or was it a little under for extra meltiness?
I don’t get why bake at 375 if you’re just setting the chocolate… seems like it could overcook the crust. I’d try a lower temp.
Short version: I love it. The lemon in the berry filling is the secret. My family ate it too fast.
Yes!! The lemon is so sneaky in the berry filling—really brightens it up. Love that your family devoured it 😄
Wait… lemon juice in blueberries? I guess it makes sense though. I’ve made similar fillings without it and it was kinda dull. Might try adding a little lemon next time.
