I take birthday cakes seriously, but after years of cake tasting during my event planning career, I rarely make a traditional cake.

Our middle kiddo, Ani, always requests and M&M Birthday Cake…when you take a bite, you’ll be requesting it for your birthday, Mother’s Day, Valentine’s Day or the average Saturday just as an excuse!

This is one of my go-to desserts because it’s easy and always such a crowd-pleaser. Who doesn’t love M&M Cake?

We love all kinds of cookie cakes in our house! You can find all of my cookie cake recipes here including classic chocolate chip cookie cake and an incredible sugar cookie cake!

This pretty M&M cake is even sweeter in a heart shaped dish, but you can make on any baking sheet with a lip, pizza pan (without holes), pie dish or tart pan! It’s your choice! However you do it, I can’t wait to hear what you think! Don’t forget to leave a five star review in the comments below.

An Unforgettable M&M Cake

Cookie cake was my top request as a child. In fact, I often prefer it over cookies because of its soft and chewy texture. My mom always made it in a pizza pan for a larger, thinner cake, which is also delicious! The thinner it is, the shorter the baking time.

This M&M cake recipe takes just 10 minutes hands-on time and doesn’t need any decoration. What could be cuter and more festive than this? 

The best part is, you can make this M&M Cake in about 10 minutes hands-on time with staple ingredients! If you’re always in a pinch like me, you’ll appreciate this!

BUT. This is no ordinary M and M Cake. A secret twist makes it out of this world. I make it with my favorite little baking secret, brown butter. One extra step makes this cake stand above the rest. It takes just a few extra minutes and it puts the cake recipe over the edge.

This is not your average sugar cookie dough! Brown butter adds a caramelized flavor to the dough that makes it irresistible. The additional flavor and texture eliminates the need to add frosting on top, though I’ll never judge if you decide to pipe it or smother it in real milk chocolate buttercream!

  7. Bake in preheated oven for 15+ minutes (depending on the depth of your pan).

The next time you think to go to the store for a cookie cake, you may want to reconsider. There’s no comparison!

Tips For The Best M&M Cake

  • Don’t over-mix! I stress this in every recipe, but it’s true. That’s how you achieve the out of this world texture and thickness!
  • Allow the brown butter to cool a few minutes. You don’t want to fry the egg (insert horror face). I promise, it’s simple.
  • Adjust baking time based on the size and thickness of your pan. The thinner the cookie cake, the less time you’ll bake.

Questions and Answers About This M and M Cake

  • Melissa says: “This looks amazing! Where did you find the heart shaped pan? I’m having trouble locating one. Thanks so much! This adorable heart shaped tart dish is finally available again! I’m so excited about that. You can also halve the recipe and use this darling heart pie dish instead, or any of your favorite baking pans.
  • Carlos asks: Do you pour the browned butter into the mix while it’s still hot? Or wait? Great question! I prefer to let it sit and cool completely, or at least until it’s closer to room temperature. This way there’s no risk of curdling your eggs when you mix them into the dough! 
  • Becky asks: Can I add the M&M’s after baking? Or is it best to add them before? I don’t mind a few cracks in my m&ms, I think they add to the charm of this sweet cookie cake. Furthermore, you’ll want them inside the dough, too, to add to the flavor and texture throughout. It should be full of chocolate!

More M and M Cake Ideas

Of course you can add frosting on top of M and M Cake for extra credit, but it’s not needed. It’s simply amazing as is! You could also let it cool completely, but I dare you to try it 10 minutes out of the oven! It makes one crazy good, crazy thick cake layer. If you prefer, divide into two smaller dishes.

Finally, if you’re a chocolate chip lover, go ahead and blend in a few milk chocolate chips! For us, the milk chocolate in the candy shell is just the perfect mix.
