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

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. I made this cake for a party. I didn’t think tasted good I almost thought it away but took it anyway. Every piece was eaten and everyone was raving about how good it was. When I finished the cookie dough icing was a little runny put in frig and it stiffen up. It was one heavy cake. Will make again soon

  2. I was able to print off the instructions for the frosting but not the cake.
    Can you email the instructions for the cake?

    1. Print the whole thing or write it out by hand. NI do not have a printer and write all reipes I like out by hand.

  3. This brownie i like ,it looks yummy and more of my clients order a chocolate cake,now i have this recile for sample for them ,now i think this is a nest seller for them.i like and love chocolate very much…

    1. I found it very hard to get the brownies out of the pan, seems to be a train wreck. Any suggestions if you don’t use goop and use the spray??

      1. There are a number of ways to prepare your pans. You can spread butter and then lightly coat with cocoa powder, you can use the homemade GOOP pan release, you can use the pan release spray found in grocery stores, you can use parchment discs in conjunction with any/all of these methods.

    2. That’s crazy.. Who in their right mind does NOT like cookie dough? U never ate is off the spoon as a child? U never let urkids eat it? Crazy comment. Why just not read the recipe as soon as u see the words cookie dough!!!! Why comment on it and ruin it for those that want the recipe. Damn. Just go buy some brownie mix..cook it….eat it… And go about ur day… Or better yet..go buy some cookie dough and eat it !!!! Thenlet’s see if u really get sick.. I bet u dont but if u do then u know how u tried to ruin it for others!!!

      Even funnier….someone agreed with u . LMAO

  4. I was concerned about all of the flour also so I used 2 cups flour and 1/2 cup of powdered sugar and didn’t have whole milk so I used Half & Half instead and it taste pretty good. I also used my scratch brownie recipe instead of boxed.I will see what my family thinks when they all come over for dinner!

  5. Looking to make this soon. When you say 2 brownie mixes, is that the mix that makes an 8×8 pan or the family mix that makes a 9×13 pan? Thank you!

    1. No, raw flour does not EQUAL ecoli. Maybe you should actually educate yourself beyond some random scare tactic article on FB.

      1. All these raw flour comments peaked my curiosity. So there have been some E.Coli outbreaks from some contaminated flour. I guess it makes sense as there is a risk with ANY raw food eaten as it hasn’t gone through a heat process to kill any bacteria. Found an article that suggests that you can toast the flour to alleviate concerns. I have personally never tried this and do not know if it changes the taste, but here you go.
        “The answer is to toast your flour. Simply spread two cups of flour on a baking sheet or Silpat, and bake for about 5 minutes at 350° F. Let cool completely. Then use the flour in your preferred cookie recipe”.

  6. Made this for a party on July 4th and everyone loved it. Made it just as is, no alterations needed. For those wanting to add sugar to the frosting. Yes, when tasting the frosting on it’s own, it may not taste like a traditional sweet frosting, however, you add chocolate chips between layers and on top of the cake giving it more sweetness. As a whole, it’s sweet enough without adding more to the frosting. I did the store bought brownie mixes and added the extra eggs to make more cake-like. It was a hit and I was told that I don’t need to ask what to bring to parties from now on, just assume it’s this cake. I also agree with the brand of vanilla recommended. I never knew I had a preference until I grabbed another big name brand once and found the taste to be odd and personally felt it ruined the cookies I was making. Thanks for the recipe!

  7. I have been waiting and waiting and waiting for a reason to make this cake! and I FINALLY have one!

    Can I make the cake a day in advance? does the icing hold up well under the weight of the brownie layers?

    Thank you

  8. I made this cake for a family party. The instructions were great, the cake was easy to do and my family loved it. Thank you for sharing the recipe.
