Brownie Cookie Dough Cake

To make this cake you will need:

2 boxes of Brownie Mix (or you can triple this homemade brownie recipe)

cookie dough frosting (below)

4 cups chocolate chips (can be milk or semi-sweet chocolate)

1 cup mini chocolate chips

small offset spatula

cake stand

How to make a Brownie Cookie Dough Cake

Begin by preparing brownie mixes according to box directions. (Or making from-scratch brownies.) Place 2 cups of brownie batter into each 8-inch round cake pan, three pans total. (To prepare the pans I generously coated them with GOOP, then placed a parchment circle in the bottom, then added more GOOP.)

Allow brownies to cool then remove from pan.

While the brownie is baking, prepare Cookie Dough Frosting.

Easy Brownie Cookie Dough Cake

Place 1 layer of brownie on the cake stand. Cover with about 1/2 cup of cookie dough frosting using a small offset spatula. Sprinkle 1/2 cup of mini chocolate chips on top. Add the next layer of brownie, cover with 1/2 cup cookie dough frosting, then 1/2 cup mini chocolate chips. Place the final layer of brownie on top and cover the entire cake with the remaining cookie dough frosting.

Now press chocolate chips into the sides and top of the cake. Fill in as much as possible.

Drizzle 1 cup of chocolate syrup (you can also use chocolate ganache) over the entire cake. Chill until ready to serve.

I am thankful that Kara from Kara’s Koutour Cakes addressed the “raw flour” issue. I could not agree with her more! SEE IT HERE

  • 1 ½ cups packed light brown sugar

  • 1 ½ cups all-purpose flour*
  • 2 teaspoons McCormick® Vanilla Extract

  • Add in flour and vanilla extract into creamed butter until fully combined.
  • With the mixer on low speed, and in milk a little at a time until fully incorporated.
  • For the Brownie Cookie Dough Cake the mini chocolate chips will be added on top of the frosting. You can also add 1 cup of mini chocolate chips directly into the frosting.
  • IF YOU DON'T WANT TO USE FLOUR out of the bag, just place it on a baking sheet in an even layer and bake at 350°F for 10 minutes. 



I triple this recipe for this cake. 
Flour Concerns: You can place the flour on a cookie sheet and bake for 5-10 minutes at 350°F before making frosting.

  1. This is so good! My boys share a birthday and they’ve both agreed and chosen this cake for the past three years.

  2. Well to be honest I haven’t cut into the cake. It is for my daughter-in-law’s birthday tonight.
    What’s not to love about brownies. I however was a little dubious about the frosting, but she had specifically ask for it so followed through. Can’t stop eating the frosting as am spreading it on.

  3. Can’t figure out what I did wrong, the icing was very runny. I checked and double checked the ingredients. I didn’t even add all the milk, and I added a little more flour. It still slid off the sides of the cake. I even refrigerated it before I put it on. Never had this happen before, and I have been baking for many years.

  4. I will try this. I will leave out the chocolate chips between the layers and melt them with some butter and spread that on in its place. Also, lose the chips on the rest of the cake and pool melted choc. in its place
