Christmas M&Ms brownies are a fun, festive treat that combine the rich, fudgy texture of brownies with the colorful crunch of M&Ms, making them the perfect holiday dessert. These brownies are not only easy to make but also a surefire crowd-pleaser, with their vibrant red and green M&Ms adding a touch of holiday cheer to every bite. Whether you’re preparing them for a family gathering, holiday party, or simply craving something sweet, these brownies are sure to become a seasonal favorite.
The base of these brownies is made from a simple yet delicious chocolate batter. Melted chocolate and butter create a rich, dense foundation for the brownies, while eggs and sugar add sweetness and structure. What makes them truly special is the addition of M&Ms, which bring a pop of color and sweetness to the brownies, while their candy coating adds a slight crunch that contrasts beautifully with the soft, gooey interior.
The beauty of these Christmas brownies is in their simplicity. Once baked, the brownies are soft, fudgy, and packed with the delicious flavor of chocolate. The M&Ms, scattered throughout the batter, melt slightly during baking but retain their vibrant colors and slight crunch, providing little bursts of sweetness with every bite. For an extra festive touch, you can press additional M&Ms into the top of the brownies just before baking, creating a more decorative, colorful look.
Christmas M&Ms brownies are incredibly versatile and can be customized to suit your taste. You can add a swirl of white chocolate, sprinkle some crushed candy canes on top for a minty twist, or even drizzle melted chocolate over the brownies once they’ve cooled for an extra decadent touch.
Perfect for holiday baking, these Christmas M&Ms brownies are a fun, easy dessert that adds a festive touch to your celebrations. The combination of fudgy chocolate, crunchy M&Ms, and holiday spirit makes them a sweet treat that will delight everyone, young and old alike.

I followed the recipe but my brownies ended up really dry. Maybe my oven is too hot? I don’t know but I was disappointed. 🙁
Maybe you put in too much flour? It can happen! Just follow the measurements precisely. And yeah, ovens can be tricky sometimes! Good luck next time!
I think your oven might be the issue, but you could also try reducing the baking time a bit. Brownies should be fudgy, not dry! Don’t lose hope; you can nail it next time! 😊
These brownies are the best! Super fudgy and that chocolatey goodness is to die for. My whole family loved them, especially the kids with the M&Ms!
I think these brownies would be good with nuts too. Just saying! Don’t hate me, but the M&Ms seem unnecessary. Just stick with plain chocolate!
These brownies were a hit at our Christmas party! So rich and chocolaty. 5 stars!
11/10, would recommend to a friend. Brownies and M&Ms, what’s not to love?
Really? I thought brownies are better without extra stuff like M&Ms. Just saying.
Absolutely! The combination is divine. I’ve made these twice already this month!
This was my first time making brownies from scratch and it was a success!!! I am so proud of myself! 🎂
I tried these and they were a bit too sweet for me. The M&Ms are just too much. 3 stars.
Too hard and crumbly. Not what I expected. Anyone else having issues with the consistency? 🙁
I had the same problem! Mine turned out super dry too. I think maybe I baked them too long? Not sure what I did wrong.
Hmm, mine were fine. Maybe try adding a bit more butter next time? Or less flour? Just a thought! 😅
I’m not gonna lie, I thought the M&Ms would get weird after baking. They stayed colorful and added little pockets of sweetness. Pretty fun dessert.
Mine didn’t stay as colorful… I think I overbaked or my oven runs hot. Still tasted good though—next time I’ll pull it at like 25 min and cool longer. Merry Christmas brownies 😅
I had the same worry about the M&Ms melting and turning nasty, but honestly they look so cute in there. Love that they kept their color and gave little sweet bursts!
I followed the recipe exactly and it was too sweet for my taste. Maybe less sugar next time?
Just okay. I think I expected too much. They were decent but not wow.
I thought brownies had to be baked? My grandma says she always microwaves them.
I don’t think that’s right… Brownies are supposed to be baked in the oven, right? Microwaving them sounds weird.
Your grandma is onto something! Microwaving can work too, but there’s just something about the oven that gives the best texture. 😋
These taste amazing but I accidentally put an extra egg in. I think it made them more fudgy. Still good.
Not impressed. My brownies came out too gooey, I don’t know what I did wrong. 2 stars.
I’m sorry to hear that! Sometimes the oven temperature can be off, or maybe they needed a bit longer to bake. Don’t give up! Try again.
Gooey? Sounds delicious to me! Maybe it’s just how brownies should be. I would totally eat those!
Mine didn’t turn out like the pic! They came out flat. What did I do wrong?
Mine took closer to 35 minutes and I almost overbaked, but they were still tasty. Next time I’ll check earlier because ovens vary a lot.
35 minutes?! Mine were done at like 28 and they were super fudgy. Maybe your oven temp is off or you used a glass pan? Either way they sound good, I’m just confused why it needed so long.
Good call on checking early—my oven runs hot too. I usually start watching around 22–24 minutes so they don’t dry out. These really are hard to overbake though with all the M&Ms!
So easy to make but I used milk chocolate M&Ms by accident and now I can’t stop eating them!
Milk chocolate M&Ms sound amazing! Honestly, I think I’d love it more that way. Can’t wait to try it!
These brownies are a hit at every Christmas party! So rich and chocolatey!
Love them! Tried it with walnuts too! Delicious! 🎉
