M&M Cookie Cake Recipe

Thick, chewy and delicious classic M&M Cookie Cake recipe with a twist that puts it over the edge.

We have been celebrating Ani’s birthday all week. Birthdays give us a fun opportunity to really celebrate a kiddo and make them feel special, especially a middle! 

We had birthday donuts, a birthday lunch at school, a pre-birthday outing at Myseum, {a fun little gem in St. Louis} and a birthday dinner. But no birthday is complete without cake.

We don’t embrace after-Christmas diets around here, celebrating three birthdays in the month of January. And my sister and I needed a little baking distraction this week, so I’m excited to bring you several new cookie cake recipes, including this M&M Cookie Cake recipe my sister and I made to celebrate sweet Ani.

Cookie cake was my top request as a child. In fact, I often prefer it over cookies because of it’s thick, 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.

But this is no ordinary M&M Cookie Cake – I make it with my favorite twist, brown butter. One additional step that takes just a few extra minutes and puts the cookie cake over the edge.

This M&M cookie cake recipe takes just 10 minutes hands on time and doesn’t need any decoration. The next time you think to go to the store for a cookie cake, you may want to reconsider. There’s no comparison!

Prep Time 10 mins Cook Time 15 mins Total Time 25 mins

Serves 24

Ingredients

• 1 c butter
• 3/4 c sugar
• 1 c brown sugar, lightly packed
• 1 Tbsp vanilla
• 2 eggs
• 1 tsp baking soda
• 1/2 tsp baking powder
• 1/4 tsp salt

• 1 c M&Ms

Topping

• cracked sea salt
• 1/2 c M&Ms

Directions

Preheat oven to 350 degrees.

In a saucepan over medium heat, melt butter. Swirl until brown in color and it has a nutty aroma. Remove from heat.

Meanwhile, combine sugar, brown sugar, and vanilla in a mixing bowl. Mix in brown butter.

Gently blend in eggs, careful not to overtax.

Sprinkle baking soda, baking powder, salt and flour over mixture and fold until combined.

Allow batter to cool slightly and fold in M&Ms. 

Scoop dough into greased baking dish or pan until just over half full.

Press M&M's into the top of the cake and bake 15 - 20 minutes or until golden brown, depending how thick your cake is.

Recipe Notes

For perfect M&M's you can press them in IMMEDIATELY after baking, I put them in before, but don't mind a few cracks.
