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 Karaโ€™s Koutour Cakes addressed the โ€œraw flourโ€ issue. I could not agree with her more! SEE IT HERE

  1. Did you cook all 3 brownie pans together? If so, how long? I know the box of brownies has a time for 2-8in pans but not 3. Thanks so much! Iโ€™m making this for Thanksgiving ๐Ÿ™‚

  2. For you chocolate chip cookie dough frosting, why are you using 2 1/2 cups of flour and nott powdered sugar? Or am I just having a senior moment.

    1. How do you cook raw flour?
      Simply spread two cups of flour on a baking sheet or Silpat, and bake for about 5 minutes at 350ยฐ F. Let cool completely. Then use the flour in your preferred cookie recipe. By carrying out this toasting process, you are killing off any bacteria that might be lingering in your flour before you’ve baked the cookies

  3. frosting tasted like paste. don’t know what i did wrong. followed the recipe to the t.
    wasted all those ingredients and time.

  4. Are you sure itโ€™s flour for cookie dough filling! I have never heard of raw flour in a recipe. Maybe you meant powdered sugar!!!!
