Cookies and Cream Cake

This cookies and cream cake recipe all starts with my perfect chocolate cake recipe. It is a rich and decadent chocolate cake that is delicious on its own! But, when you layer in the creamy Oreo buttercream with added Oreo cookies, this cake really takes the cake, if you will.

Cookies and Cream Cake Ingredients

There are three main parts to this cookies and cream cake recipe–the chocolate cake, Oreo buttercream, and crushed Oreo cookies.

Room Temperature Ingredients: Using room temperature ingredients will help you get the best results when baking the cake and making the buttercream. Butter is at room temperature at 65°F. Don’t put it in the microwave to soften it; simply cut it up into small pieces and let it sit out if you forgot to take it out of the refrigerator.

ButtermilkThe buttermilk should also be at room temperature. You can make your own buttermilk if you don’t have any on hand.

Coffee: Yes, there is brewed coffee in the cake recipe (use decaf or regular). The coffee enhances the flavor of the chocolate. The cake does not taste like coffee at all… it simply tastes richer. If you simply must not use coffee, you can substitute hot water.

Oreo Cookies: Don’t forget about the cookies in this recipe. If you want your buttercream to have that signature velvety texture, make sure you finely chop the cookies (I use a food processor). The cookies can be more chopped for the topping.

How to Make the Perfect Chocolate Cake

This is truly a moist and flavorful chocolate cake. Is there anything worse than dry cake? Nope. You will never have that problem with this recipe! Plus, the added coffee does magical things to the chocolate flavor. I used two 8-inch pans for my cake, but you can also use 9-inch pans. If using 9-inch, you will want to decrease the bake time by up to five minutes. And don’t forget to use GOOP to prepare your pans… it is the BEST!

To get started, preheat the oven to 350°F and get out your round cake pans. (Don’t forget about the GOOP–homemade pan release.) In a large bowl, whisk together the flour, sugar, cocoa, baking soda, baking powder, and salt. In a separate bowl, combine the buttermilk, oil, eggs, and vanilla.

Mixing on low speed, slowly add the wet ingredients to the dry. Add the coffee and mix until just combined. Use a rubber spatula to scrape the sides and bottom of the bowl. Pour the batter equally into the prepared cake pans and bake for 30-40 minutes, or until an inserted toothpick comes out clean with a few dry crumbs (but no wet batter).

When the cakes are done, let the cakes cool in the pans for about half an hour before turning them out on a cooling rack to cool completely. If you are making adaptations at a higher altitude, be sure to check out my High Altitude Baking Tips.

How to Make Oreo Buttercream

I love buttercream frosting because of how versatile and easy it is to make, and this Oreo buttercream is no exception. It’s a frosting and Oreo cookies colliding in the most delicious and creamy way. To make the frosting for the Cookies and Cream Cake, beat the room temperature butter until light and smooth. Slowly add 2 cups of the confectioners’ sugar, mixing until smooth. Stop to scrape the sides of the bowl, if necessary.

Add the remaining confectioners’ sugar, 2 cups at a time, mixing well after each addition. Then, fold in the Oreo cookie crumbs and mix until smooth. Finally, add the milk, one tablespoon at a time, until you get your desired consistency.

Buttercream can be made in advance, so save yourself some time and make it ahead of time.  Store in the refrigerator for 1 week, or in the freezer for 3 months.

After the chocolate cakes have cooled and the buttercream is made, it’s time to assemble the cookies and cream cake to cut and serve! Place one cake on a serving plate. You can level the cake if you choose, or check out how to bake a level cake.

Spread about a cup of buttercream over the top of the cake, followed by some of the chopped Oreo cookies. Next, add the second layer of cake and frost with the remaining Oreo buttercream and chopped cookies. Slice and serve! Store the cake in the refrigerator for up to three days.

  1. This is my go-to cake. Every time I make it people ooh and ahh over it. I use whipped cream for the frosting instead because my family doesn’t like frosting. Delicious every time!
