This Oreo cake is an Oreo lovers dream. My favorite part is the filling. It is whipped cream cheese full of crushed Oreos for the cream. It tastes just like an Oreo no bake pie filling!
The chocolate cake layers are super soft and the cake is topped with an Oreo buttercream frosting. There are plenty of Oreo cookies in this dessert!

Tips for making the cake.

Here are my tips, so yours turns out like this recipe! If you need more tips for the frosting, I have a post on how to make Oreo frosting.

  • Tip 1: Don’t overpack your flour. If you stick your measuring cup into the flour, it will compact it down. This leads to more flour and a drier cake.
  • Tip 2: Make sure to pull out your dairy ingredients 2 hours before using. To have cake batter and frosting that blends well, your ingredients need to be room temperature.
  • Tip 3: The filling, frosting, and chocolate drip should be made right before you need it.
