Easy Chocolate Oreo Cake Recipe

Easy chocolate Oreo cake recipe from scratch filled with Oreo buttercream frosting and topped off with chocolate ganache. Perfect soft, moist birthday cake!

This EASY Oreo cake recipe is one of my son’s favorite cakes, which he even requested for his last birthday.

Now, I have seen a variety of Oreo BIRTHDAY cakes but this is my creative spin on it.

The Oreo cake filling in this cake is to die for… I swear I can eat it by the spoonfuls! lol.

It’s SMOOTH and CREAMY and packed with that wonderful Oreo cookie flavor.

Overall, this naked layer cake is SOFT and very MOIST.

Easy Oreo Cake Recipe

Here are some TIPS for this easy Oreo cake recipe:

  • DON’T replace oil with butter in the cake since that will change the texture dramatically and make it dense.
  • DON’T replace buttermilk with regular milk or vegan milk because that would change the texture of the cake.
  • Instead of making your own Oreo cookie crumbs, just BUY them because that will be easier and quicker.
  • If your icing is too thin, THICKEN it with more powdered sugar. If it is too thick, THIN it with additional milk or heavy cream.
  • Use the best quality of cocoa powder in the cake and best quality of chocolate for the ganache.
  • To PREVENT the Oreo cookie decorations on top of the cake from becoming soggy, add them just prior to serving.
  • The number of servings you get from this recipe will VARY, depending on how thick or thin you like your slices.
  • For vanilla Oreo cake recipe, replace Oreo buttercream frosting with my classic American buttercream frosting OR Cooked flour buttercream (Ermine frosting).
  • For Oreo cake recipe with cake mix, make the cake according to the box instructions. Then, cut it in half and fill it with my Oreo frosting. Also, cover the entire cake with this frosting. Then, top it off with ganache and chopped Oreos.
  • For Oreo pudding cake, I suggest making a poke cake. Prepare the chocolate cake in a rectangle cake pan instead of circle pans. The, poke holes throughout the cake with a bubble tea straw. Prepare instant pudding mixture and pour it over the cake. Allow the cake to set in the fridge and top it off with frosting or whipped cream.
  • For Oreo cake recipe (no bake), I would suggest making an ice box cake with layers of whipped cream or ice cream and Oreo cookies.
