Ingredients

Scale

Cake Ingredients

  • 2 cups (240g) all-purpose flour, spooned and leveled
  • 1 & 1/4 cups (250g) granulated sugar
  • 1/2 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 cup (1 stick / 115g) unsalted butter, cubed and softened to room temperature
  • 1/4 cup (60mL) vegetable oil or any neutral flavored oil
  • 3 large egg whites, at room temperature
  • 2/3 cup (160g) sour cream, at room temperature
  • 1/4 cup (60mL) milk, at room temperature
  • 20 Oreo cookies (225g), broken into chunks

Buttercream Frosting Ingredients

  • 14 Oreo cookies (150g)
  • 1 & 1/2 cups (3 sticks / 340g) unsalted butter, softened to room temperature
  • 1/2 teaspoon salt
  • 6 & 1/2 cups (845g) powdered sugar, sifted
  • 4 to 6 tablespoons milk

Instructions

  1. Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Butter three 6-inch cake pans and line the bottoms with parchment paper. Lightly coat the sides with flour and tap out any excess flour. Set the pans aside.
  2. Make the Cake Batter: In a large bowl, combine the flour, sugar, baking soda, baking powder, salt, and cubed unsalted butter. Use a fork, pastry cutter, or an electric mixer on low speed to mix until the butter pieces are pea-sized. In a separate medium bowl, whisk together the vegetable oil, egg whites, sour cream, and milk until smooth. Add the wet ingredients to the dry mixture and beat until the batter is silky and no dry flour remains, mixing just a few extra times to combine. Avoid overmixing.
  3. Fold in Oreo Chunks: Gently fold the broken Oreo cookie chunks into the batter until evenly distributed, taking care not to overmix.
  4. Divide and Bake: Evenly divide the batter into the prepared cake pans and spread it into an even layer. Bake in the center of the preheated oven for 25 to 30 minutes or until a skewer inserted into the center comes out clean. If the cakes brown too quickly on the outside but are still undercooked inside, tent with aluminum foil and continue baking.
  5. Cool the Cakes: Let the cakes cool in the pans for about 5 minutes. Then turn them out onto a wire rack and allow them to cool completely to room temperature.
  6. Prepare Oreo Buttercream Frosting: In a food processor, pulse the 14 Oreo cookies until finely ground and set aside. In a large bowl, cream the softened butter with salt using an electric mixer on medium speed until smooth and fluffy, about 2 minutes. Gradually add the sifted powdered sugar on low speed until combined, then whip on medium-high speed for 2 to 3 minutes until pale and fluffy. Mix in 4 tablespoons of milk and add more milk, one tablespoon at a time, to reach a spreadable consistency. Optionally, reserve about 3/4 cup of plain vanilla frosting for decoration.
  7. Combine Oreo Crumbs with Frosting: Stir the Oreo crumbs into the buttercream frosting until thoroughly mixed.
  8. Assemble the Cake: Place one cake layer on your serving plate and spread about 1/4 cup of Oreo frosting over the top. Repeat layering with the remaining layers and frosting. Frost the entire exterior of the cake with the remaining frosting.
  9. Decorate and Serve: Decorate the frosted cake with crushed Oreos and optionally pipe some of the reserved plain vanilla frosting on top for a finishing touch. Slice and serve your delicious Oreo Cake.

Notes

  • If you do not have three 6-inch cake pans, bake the batter in batches, ensuring to cool and re-grease and line the pan before each batch.
  • Do not overmix the batter to keep the cake tender and avoid toughness.
  • Use room temperature ingredients to ensure the batter mixes evenly.
  • Adjust milk quantity in frosting to achieve your desired spreadable consistency.
  • Tenting cakes with foil helps prevent over-browning while baking through.
  • Reserve some plain frosting to add decorative contrast when finishing the cake.
