  • 3 3/4 cups granulated sugar
  • 1 1/2 cups cocoa powder unsweetened
  • 2 teaspoons baking powder
  • 1½ teaspoons baking soda
  • 1 teaspoon salt
  • 1 cup milk whole
  • 1 cup sour cream full-fat
  • 1 3/4 cups coconut oil or canola oil, coconut oil should be liquified
  • 4 egg large eggs plus 3 large egg yolks
  • 1 tablespoon vanilla extract
  • 1 1/2 cups water hot
  • 39 Oreo cookies
For the Oreo Chocolate Frosting:
  • 4 1/2 cups confectioners sugar sifted
  • 1 1/4 cups unsweetened cocoa powder sifted
  • 2 unsalted butter sticks (8 ounces), very soft
  • 2/3 cup half-and-half more if needed
  • 1/2 teaspoon salt
  • 2 teaspoons vanilla
  • 1 cup oreo cookie crumbs crushed, filling removed, divided

Instructions

For the Triple Layer Oreo Cake:
    Cup of Yum
  1. Preheat oven to 350º (F). Prepare three 9-inch metal cake pans by spraying them generously with baking spray or generously buttering and lightly flouring. Arrange 13 oreo cookies on the bottom of each pan; set aside.
  2. Add flour, sugar, cocoa, baking powder, baking soda, and salt to a large bowl or the bowl of a stand mixer. Whisk through to combine or, using your paddle attachment, stir through flour mixture until combined well. Set aside.
  3. In a large bowl combine the milk, sour cream, oil, eggs, yolks, and vanilla; mix well to combine. Slowly add the wet ingredients into the dry ingredients, mixing until just combined. Then, carefully, add the hot water to the cake batter. Beat on medium-low speed until evenly combined. Be careful not to over mix here - it's easy!
  4. Distribute cake batter evenly between the prepared cake pans (I measured out about 3 1/4 cups per pan). Bake for 25-28 minutes, or until a toothpick or cake tester inserted in the center comes out clean.
  5. Remove from the oven and allow the cakes to cool for about 5 minutes before carefully removing from the pan and transferring to a wire rack cool completely.
In the meantime, make the Oreo Chocolate Frosting:
  1. Sift together the confectioners sugar and cocoa powder, whisking well to ensure it's bump and lump free!
  2. Using a handheld mixer OR a stand mixer fitted with the paddle attachment, beat the butter on medium-high speed until creamy; about 2 minutes. Reduce speed to low and slowly add the sifted sugar/cocoa powder, alternating with the half and half, then add the vanilla and salt. Stir in half of the cookie crumbs. Once all of the ingredients have been added, beat on high speed until light and creamy and combined; beat for at least 1 minute on high.
  3. Frost cooled cake layers as desired. Decorate with remaining cookie crumbs.

Notes

  • Half and half is a product found in most dairy sections; it is half milk, half heavy cream. If you cannot find it, simply mix half milk and half cream together.
