Stained Glass Gelatin Cake is a show-stopping dessert that’s as fun to make as it is to eat. With vibrant layers of colorful gelatin embedded in a creamy base, it’s like a work of art on your plate. This whimsical cake is perfect for celebrations, potlucks, or when you want to add a bit of flair to your dessert table.
The beauty of Stained Glass Gelatin Cake lies in the colorful gelatin pieces that create a stained-glass effect. The gelatin is prepared in multiple colors, usually red, green, yellow, and blue, and set into individual layers in a baking dish. Once the gelatin has firmed up, it’s cut into cubes and suspended within a creamy, fluffy filling that gives the cake its signature smooth texture.
To make this dessert, you’ll start by preparing the gelatin layers. Choose your favorite gelatin flavors and dissolve them in boiling water. Pour each flavor into separate containers and refrigerate them until they are fully set. After the gelatin has firmed, cut it into small cubes, keeping the colors separated. The more vibrant the colors, the more stunning the final effect will be.
The next step is creating the creamy base. Typically, the filling is made from a combination of sweetened condensed milk, whipped cream, and gelatin to help it set. The creamy mixture is poured over the colorful gelatin cubes in a baking dish, allowing the colorful pieces to be evenly distributed throughout. Once the base has set, the result is a beautiful, colorful dessert that looks as though it could be a stained-glass window.
This cake is as much a visual treat as it is a delicious one. Each bite offers a refreshing, fruity burst from the gelatin and a creamy richness from the filling, making for a perfect balance of textures. It’s a dessert that’s sure to be a conversation starter, and its vibrant colors make it an eye-catching addition to any table.
Stained Glass Gelatin Cake is not only a delicious dessert, but it’s also a fun and creative way to impress your guests with your baking skills. Whether you’re making it for a holiday, a birthday, or just because, this cake is a delightful treat that’s guaranteed to bring a smile to anyone who sees it.
It’s a colorful, eye-catching dessert made with cubes of brightly flavored gelatin suspended in a creamy, milky base. The mosaic-like appearance gives it the name “stained glass” or “broken glass” gelatin cake.
Not at all! It just takes a bit of patience. First, make several flavors/colors of gelatin, let them set, cut into cubes, and mix them into a sweet gelatin and condensed milk mixture. Pour into a mold and chill until set again.
It’s light, fruity, and creamy! The different gelatin flavors add fun bursts of fruitiness, while the creamy base keeps it smooth and balanced.
Use a sharp knife dipped in hot water and wiped clean between cuts to get neat, glass-like edges.

Easy and delicious! Made it for a potluck and everyone asked for the recipe!
So easy to make! I didn’t have all the flavors but used what I had and it still turned out great.
I tried it but my cubes started to melt into the creamy layer. Maybe my gelatin wasn’t firm enough or I mixed too vigorously. Still tasted good though—just not as pretty.
Who knew gelatins could look so cool? I want to try it for my next family gathering.
I think this recipe is wrong. Shouldn’t you add sugar somewhere?!
I think it tastes great as it is! The sweetened condensed milk adds plenty of sweetness already. No need for extra sugar.
I dunno. I mean sugar is usually in desserts, right? Just feels odd to me without more sugar. 🤔
Can you make it without the condensed milk? I’m lactose intolerant. 😩
Easy to make! Just remember to cut the gelatin into small cubes. It can be a little messy but totally worth it!
I made it last weekend and it turned out great! It’s super pretty too!
It looks pretty but was a pain to do. Took me forever to cut those jellies. Not sure it was worth it.
Yummm! So colorful! I love desserts that look good. Will try this 😋
I totally agree! This looks so pretty! Can’t wait to make it for my party! 🎉
Looks nice but is it really gonna taste good? I don’t know about mixing all those flavors…
Is it really necessary to wait for so long? Seems like a lot of waiting for just some jelly.
Tastes good but too many steps for me. Simple is better!
I don’t know… Seems like a lot of work for just gelatin. Not sure if I’ll try it.
This cake is so pretty! I made it for my daughter’s birthday and she loved it! 🎉
Looks delicious, but I think I could never make something so fancy. Not my skills.
This is such a fun recipe! I made it for my kid’s birthday and they loved it. 🌈
Not gonna lie, gelatin dessert is kind of my weakness. The cutting and stacking was kinda stressful, but once it set overnight it sliced way cleaner. Solid party idea.
Yes!! This is exactly the kind of party dessert I love—pretty but not crazy once you follow the steps. The overnight set making it slice cleaner is so true.
I tried something similar but my gelatin cubes just turned into mush 😅 I think I didn’t chill long enough. Also, “cut into cubes” feels harder than it sounds—do you mean really small cubes? Still sounds tasty though.
ugh, this is so boring 😒. Jello is jello. Not worth it.
This looks so fun—like actual stained glass for dessert. I love how the cubes stay distinct instead of turning into one blob. Definitely trying this for a party.
I made this for my kids’ birthday and they loved it! A hit for sure!
Too many steps for me. I just want a simple dessert, not an art project! 🤷♂️
Not really my vibe. Looks like a science experiment that went wrong! But hey, I’m not judging.
I think it looks kinda fun! A cake that looks like art? Count me in! 🎨
Science experiment? More like a delicious dessert! Maybe you just don’t appreciate creativity. 🙄
This seems like a kid’s dessert. Why would adults want this? 🤔
I think adults can enjoy this too! It’s all about nostalgia and fun! 😊
Super easy to make! My kids loved it! Only thing is my gelatin didn’t set right… maybe I added too much water.
Glad your kids enjoyed it! Maybe try less water next time? That might help the gelatin set better.
I made this last week, but I forgot to put it in the fridge! It was a puddle. Total disaster.
Yum! Just made this for a family gathering and it was gone in minutes! Everyone loved the colors.
This cake is super fun! I made it last week too and the kids went crazy over it! 🎉
Looks good but isn’t it just jello with milk? Seems kinda basic…
I made this but it was too sweet for me. Maybe less condensed milk next time?
I tried making it but it didn’t set right. Can anyone help? What did I do wrong?
IDK why, but this recipe ruined my dinner plans. The gelatins didn’t set right. 😩
What’s with the unflavored gelatin? Isn’t that just a waste? 🤔
But like, why not just use more flavored gelatin? Unflavored seems kinda pointless. 🤷♀️
I think the unflavored gelatin is important for the texture! It helps give the cake that creamy base. It’s not a waste, it’s part of the magic! 🪄
Wow, this reminds me of when I was a kid! My mom used to make something like this, but we called it sparkle cake. Love it! 👍
This is such a sweet memory! My grandma made something similar too, though she never used condensed milk. Gonna give this a try! 🥳
Sparkle cake? Never heard of that. Seems a bit strange to me to mix all those jell-o flavors. Hope it tastes better than it sounds! 🤔
Very colorful! Made it for a potluck and it vanished in seconds! Can I use different flavors?
This recipe is great, but my layers kinda got mixed up… still tasted good! Next time I’ll be more careful!
This looks *so* fun—like a dessert stained glass window. I’d definitely try it for a party. The condensed milk base sounds dangerously good.
This is just sugar with sugar. I don’t get why people like jello this much.
SO good! I used tropical flavors instead of the regular ones. Everyone said it was the best thing ever!
Stained glass? More like jello-o-rama! Haha, I love the colors and the idea. Dinner party will be a hit!
Why do you need the unflavored gelatin? Seems unnecessary. 🤔
I dunno, maybe you could leave it out? Seems like you just wanna add flavor 😂. But I guess it’s to make it creamy or sumthin? 🤷♂️
The unflavored gelatin helps to set the whole thing together without adding more flavor. It gives that creamy base! Totally necessary in my opinion!
GREAT! Colorful and jelly is fun! But a bit too sweet for me.
I love it too! The colors are so pretty! Maybe you could use less sugar next time?
OMGGG this was the hit of the party! Everyone was like wow how’d you do this? 😍
That’s amazing! I’m so glad everyone enjoyed it! It really looks so pretty too! 😍
Five stars for creativity, but gelatin desserts are a gamble in my kitchen 😅. Also 3 hours for the first layer felt short—mine took longer to really firm up.
This cake looks so amazing! Can’t wait to make it for my daughter’s birthday. Thanks for sharing!
I don’t know… Gelatin is kinda weird to me. I guess it’s okay for kids?
The instructions are hard to follow. Can someone explain step 4?
Step 4 is where you mix the unflavored gelatin with boiling water. Just make sure to stir it really well until it all dissolves, then add the cold water. It’s pretty simple! Hope that helps!
Yummy! My kids loved it. Easy to make and fun to eat. Will definitely make again!
I’m not sure about 2 envelopes of unflavored gelatin—will it be sturdy enough once you cut the cubes? Might depend on the gelatin brand.
I was confused about cutting the flavors. I just mixed it all together. LOL!
Did u really put milk in it? Seems kinda weird! 🤔 But maybe I’ll try it.
Wow, this sounds so colorful and fun! Can’t wait to try it for my kid’s birthday party.
But is it really safe for kids? That’s a lot of sugar, right?
This looks awesome! My kid will love it, thanks for sharing!
This recipe looks so pretty! Can’t wait to try it for my kid’s birthday party! 🎉
This recipe is amazing! I bet the kids will love it! 🥳
Looks fun, but isn’t gelatin just jello? 🤔
I mean, come on. Is this really a dessert? It just seems like a bunch of colored water to me. 😒
Stained glass? No way is this for real. Seems like too much work.
This looks amazing! Can’t wait to try it at my next party. 🍰
Looks too complicated for me, I don’t have the patience for all those layers. 😅
So excited for you! This cake is always a hit at my gatherings. 🎉
Is there a way to make this sugar-free? My kids are all hyped up on sugar already.
You could try using sugar-free flavored gelatin and maybe some alternative sweeteners for the milk part. Just a thought!
This looks so colorful! Can’t wait to try it for my kid’s birthday party!
This looks so pretty! Can’t wait to make it for my daughter’s birthday party. 🎉
I don’t get why people would want a gelatin cake. Seems kinda weird to me. But maybe I’ll try it.
This is cool but also why did you use so many different flavors? Can’t we just stick to one?
Tried making this for my kid’s birthday. They loved it! Super easy to make. 👍
That’s awesome! Happy to hear it was a hit! 🎉 Children always love colorful food!
This cake is SO pretty! I made it for a party and everyone loved it!
Made this with my kids! They had a blast cutting the gels and watching how it comes together. Will def do it again.
I tried this with my grandma but she says the gelatin is too sweet. Maybe less milk next time?
This cake tastes like a sugar bomb. I’d rather have plain jello. Sorry, but no thanks!
Y’all ever thought about using actual fruit instead? Just a thought…
I have to be honest, I’m skeptical about the milk in this. Gelatin and milk? Sounds weird…
I followed the recipe, but mine came out super runny. Maybe I did something wrong?
Why don’t you just make the gelatin and eat it? This seems extra.
But that’s the whole point! It looks pretty. Eating just plain gelatin is boring!
I dunno, seems like a lot of work for just some jello. Can’t you just mix it up and call it a day?
I followed it exactly but my cubes floated to the top and kinda muddied. Not sure if my mold was too shallow or if I stirred too hard in step 6. Still tasted good!
I’m not sure about the sweetened condensed milk part. Seems kinda weird. 🤔
Looks pretty but it’s just jello, not a cake! I mean really…
My grandma used to make a similar thing but with fruit slices. This is just weird, but I guess it’s okay.
I think this is just a fancy jello dish. Not sure it’s worth the time, honestly.
Bland. I expected more flavor from the milk but it only tastes like gelatin.
Really pretty! It’s a hit at my parties. Makes me look so fancy!
Quick question: do you have to use unflavored gelatin *envelopes* and boiling water like that? I used gelatin powder once and it didn’t set right. Might be my fault, not the recipe.
Could someone explain what unflavored gelatin is? I thought it was a myth! 🤔
Made this for Easter and it was a hit. Everyone loved the flavors! Yum!
This sounds amazing! I can’t wait to try it for my family gathering next week.
Disgusting! Who uses sweetened condensed milk in a dessert? What a mistake!
I don’t like the taste of sweetened condensed milk. Can I leave it out? 🤷♂️
Tastes great, but took forever to set! Next time I’ll just buy jello from the store >:(
Gonna add some fruit bits in it next time, make it healthier!
WOW this is actually beautiful. I’ll make it for my aunt’s birthday and act like I’m a fancy pastry chef 😂
Made something similar before but never layered it with cubes like this. The instructions are clear enough, and the “at least 3 hours” part is realistic.
Love the stained glass look—layering/cubes always makes it feel fancy. I’ll try it. 🍓🫐
I tried it and it was a hit! Everyone loved the different flavors. Thanks for sharing!
Yummy! Reminds me of my childhood! Made it with grape and orange jello 😋
I don’t get how the milk part works. What if it curdles?
This cake looks so pretty! Perfect for parties! 🌈
Just a heads up, you need to really wait for it to set properly. I was too impatient and it was runny.
Thanks for the tip! Patience is key, right? I’ll make sure to let it set next time.
Gelatin? I though you’re supposed to use ground beef for cake! 🤷♂️
I dunno if I like this idea… Gelatin is just sponge in my opinion.
Yum!! I love jello! This gonna be my dessert for the family reunion. They’ll love it! 😍
That sounds like a great choice! Jello is always a hit at family gatherings. Hope it turns out perfect! 😊
Not sure if this is gonna be a hit. Jello kinda reminds me of school lunches. But good luck! 🍀
Lit 🔥 Can’t believe I never thought of this before. Totally making it for the next BBQ!
Came out super wobbly (in a good way). I used lime, strawberry, and blueberry like the recipe said and it looked amazing in the glass dish. Next time I’ll chill the bowl too before pouring.
Love this! “Wobbly (in a good way)” is exactly what I want from gelatin desserts 😄 Chilling the bowl makes sense too—will try that next time.
I don’t know about that sweetened condensed milk stuff. Can’t you just use regular milk? 🤔
I understand your concern, but sweetened condensed milk adds a creaminess that regular milk just won’t give. 😋
But wait, isn’t regular milk like, healthier? I dunno, can you just try it without the sweetened stuff?
Super easy! Just follow the steps! My mom used to make this and it brought back memories. ❤️
I don’t know… it looks a bit too sweet for my tastes. Don’t think I’ll try it.
This brings back memories for me too! My grandma used to make it every summer. Love this recipe! 🥰
This is awesome! So colorful and refreshing. My kids loved it!
Looks good, but I’m not sure about using that much gelatin. Isn’t it a bit unhealthy? 🤔
I’m glad your kids enjoyed it! It’s such a fun dessert. I made it for my daughter’s birthday and it was a hit!
What the heck, why do you need 3 hours for it to chill? I have no patience for that.
This looks amazing! Can’t wait to try it at my family gathering! 🌈
I tried it and mine turned out kind of cloudy—not sure if I dissolved the unflavored gelatin long enough. Tasted great though.
Ok but 1 cup boiling water?? That seems like a ton compared to the 1/2 cup cold water. Still, if it’s per envelope directions it should be fine.
Yeah I was side-eyeing that too 😅 but boiling water is mainly to bloom/dissolve the unflavored gelatin. The cold water is to cool it so the condensed milk doesn’t mess up. As long as you stir till it’s fully clear.
I tried it once and it came out kinda weird—like it didn’t set super clean. I think I added cold water first by mistake. But you’re right, if you follow the envelope then the amounts should balance out. Still, “boiling” seems excessive lol
I love gelatin desserts and this one is basically edible art. The flavors (strawberry/lime/blueberry) combo is spot on.
