Ingredients

Cake:

Oreo Buttercream:

Assembly:

  • 10 Double-Stuffed Oreos chopped

Instructions

Cake:

  • Preheat oven to 350F, grease three 6" round baking pans and dust with cocoa powder. Line bottoms with parchment.
  • Place all dry ingredients into the bowl of a stand mixer fitted with a paddle attachment. Stir to combine.
  • In a medium bowl whisk all wet ingredients (pour coffee in slowly as not to cook the eggs if very hot).
  • Add wet ingredients to dry and mix on medium for 2-3 mins. Batter will be very thin.
  • Pour evenly into prepared pans. I used a kitchen scale to ensure the batter is evenly distributed.
  • Bake until a cake tester comes out mostly clean. A total of 30-35mins.
  • Cool 10minutes in the pans then turn out onto a wire rack to cool completely. Once cooled, cut each layer in half horizontally to get 6 layers.

Oreo Buttercream:

  • Place egg whites and sugar into the bowl of a stand mixer, whisk until combined.*
  • Place bowl over a hot water bath on the stove and whisk constantly until the mixture is no longer grainy to the touch (approx. 3mins).
  • Place bowl on your stand mixer and whisk on med-high until the meringue is stiff and cooled (the bowl is no longer warm to the touch (approx. 5-10mins)).
  • Switch to paddle attachment. Slowly add cubed butter and mix until smooth.
  • Add vanilla and Oreo cookie crumbs. Whip until smooth.**

Assembly:

  • Place one layer of cake on a cake stand or serving dish. Top with about 2/3 cup buttercream and sprinkle with chopped Oreos. Repeat with remaining layers. Frost and smooth the outside. Add additional Oreo cookie crumbs along the bottom and top if desired.

Notes

* Ensure there is NO trace of egg yolks in your whites and that your mixer bowl and whisk is completely grease free or your meringue won't stiffen.
** The buttercream may look like it's curdled at some point. Keep mixing until it is completely smooth.
