  • Stand Mixer



  • 2 ¾ cups cake flour or all-purpose flour
  • 1 ¾ cups granulated sugar
  • 1 ¼ tsp baking soda
  • 1 ¼ tsp baking powder
  • 1 tsp coarse Kosher salt
  • 3 large eggs
  • 1 ¾ cups whole buttermilk
  • ¾ cup vegetable oil
  • 2 tsp vanilla extract
  • ½ pkg Oreos, each cookie cut in 4ths

Buttercream & Monster Eyes

  • 2 cups unsalted butter, softened to room temperature
  • 4 cups powdered sugar
  • 1 tbsp meringue powder (optional)
  • ¼ tsp coarse Kosher salt
  • 2 tsp vanilla extract
  • 2-4 tbsp milk or cream, if needed
  • ½ pkg Oreos
  • 1 pkg M&Ms



  • Preheat the oven to 350 and grease three 8-inch pans with non-stick spray.
  • In a large bowl, whisk together the dry ingredients.
  • Add the wet ingredients and whisk until well combined, then fold in the Oreos.
  • Divide the batter between the pans and bake for 20-25 minutes, until a toothpick comes out clean.
  • Set the pans on wire racks, cover loosely with clean kitchen towel and cool completely.


  • In the bowl of your stand mixer fitted with the whisk attachment, beat the butter for one minute until smooth.
  • With the mixer on low, gradually add the powdered sugar, meringue powder and salt and mix to combine.  Add the vanilla and milk/cream and whip on medium high for 4-5 minutes until light and fluffy.
  • Fill the cake layers and frost all over with a thin crumb coat of buttercream (I also sprinkled the extra M&Ms between each layer for crunch).  Refrigerate for 20 minutes.
  • Meanwhile, carefully twist apart the Oreos and set aside the frosted side for the eyes.
  • Roughly chop the unfrosted sides of the Oreos and fold into the remaining buttercream (don’t over-mix, or the crumbs will turn the frosting gray).  Frost the cake with the Oreo buttercream.
  • Press M&Ms to the frosted cookies and stick onto the cake for the monster eyes.


  1. The reason I wait to add the Oreos to the buttercream until after doing the crumb coat is that they would make it very difficult to get a smooth crumb coat on the cake with all the cookies mixed throughout.
  2. Leftover cake should be stored at room temperature in an airtight container for up to 3 days.
