Birthday Cake Oreo Cookie Recipe

Several months ago I posted a recipe for a Birthday Cake Cookie. It was a delicious vanilla cookie topped with cake batter icing. People went crazy over it, and it got me thinking, I know at one point there was a birthday cake flavored Oreo and there may have even been a cookie similar to this featured at a local cookie shop, so I may as well give it a whirl, right? And let me tell you, the results are divine!

Truth be told I could eat this Oreo cookie all on its own. It is soft, fudgy and super chocolatey. But then when you top it with cake batter buttercream…FORGET ABOUT IT! It becomes everything you could ever want in a cookie!

Ingredients for Birthday Cake Oreo Cookies

Keep scrolling for the exact ingredient amounts and specific instructions.

For the Cookie

  • Butter- I always use salted butter. And make sure that it is room temperature. It will need to be softened in order to cream well with the sugars. Don’t try and substitute margarine, it won’t work!
  • Granulated Sugar
  • Brown Sugar- The combination of white and brown sugar create a wonderful texture and help the cookie stay moist.
  • Eggs
  • Vanilla
  • Flour- Just plain All Purpose flour will do the trick. Nothing fancy needed here!
  • Black Cocoa Powder- This is different than dark cocoa powder, and its key in getting the classic Oreo color and flavor. I purchased mine on amazon- you can use my affiliate link and purchase some black cocoa on amazon if you need some!
  • Crushed Oreos- You will need the family size package.
  • Baking Soda
  • Baking Powder
  • Salt

For the Buttercream

  • Softened Butter- Again you want it soft so that it can get nice and smooth.
  • Cake Batter Flavoring– I use Lorran’s brand. Again, this can be purchased on amazon.
  • Powdered Sugar
  • Milk- You won’t need a lot of milk here, but this is just to get the icing to the right consistency.

How to Make Birthday Cake Oreo Cookies

Start by preheating the oven to 350 degrees.

In a stand mixer, cream together the butter and the sugars. Add the eggs and vanilla and mix again until the batter is light and fluffy. Add in the flour, black cocoa, Oreo crumbs, salt, baking powder and baking soda and mix until just combined.

Separate the dough into twelve 1/2 cup portions. Roll each piece into a ball and place 6 balls per cookie sheet. Press down on each ball to flatten it slightly.

Bake for 12-15 minutes. After removing the cookies from the oven allow the cookies to cool on the pan for about 20 minutes. Because the cookies are so large allowing them to cool on the pan will allow them to finish cooking through with out them getting overbaked!

While the cookies are cooling down make the frosting by creaming the butter until it becomes light. Slowly add the powdered sugar and cake batter flavoring and continue to mix until smooth. . Then add the milk one tsp at a time until you reach the desired consistency.

When the cookies have cooled, use a piping bag with a large round tip, or a gallon size zip top bag with the corner cut off and frost the cookies in a spiral. Start in the center of the cookie and work your way out.

Top with sprinkles and serve warm.

Can I make the cookies smaller?

Definitely! You’ll bake at the same temperature, but you’ll need to adjust the cook time. I’d start with 9-11 minutes, but definitely watch your cookies. The cookies will spread a bit, start to crackle and the center of the cookie will no longer look wet and glossy. Those are your signs to take the cookies out of the oven.

My cookies were really dry, what happened?

Dry cookies mean they were over baked. Baking too long will result in dry cookies, which is not what we want! Cut the cook time by a few minutes next time.
