Ingredients

Scale

Dry Ingredients

  • 2 cups all-purpose flour (Gluten-free option available)
  • 3/4 cup unsweetened cocoa powder (Dutch-process recommended)
  • 2 cups granulated sugar (Brown sugar can be used for added moisture)
  • 1 tbsp baking powder (Use fresh)
  • 1 tbsp baking soda
  • 1 tsp salt

Wet Ingredients

  • 2 large eggs (Flaxseed or applesauce substitute for vegan option)
  • 1 cup whole milk (Almond or soy milk for lactose intolerance)
  • 1/2 cup vegetable oil (Melted coconut oil as alternative)
  • 2 tsp vanilla extract (Pure vanilla preferred)
  • 1 cup boiling water

Frosting and Decoration

  • 1 cup unsalted butter (softened)
  • 4 cups powdered sugar (sifted)
  • 1/4 cup heavy cream (Coconut cream for dairy-free option)
  • 1 cup crushed Oreo cookies (can use different flavors)
  • 6 whole Oreo cookies (for decoration)
  • 1/2 cup chocolate ganache (optional)

Instructions

  1. Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans to prevent sticking.
  2. Mix Dry Ingredients: In a mixing bowl, whisk together the flour, cocoa powder, granulated sugar, baking powder, baking soda, and salt until well combined with no lumps.
  3. Add Wet Ingredients: Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix using an electric mixer until the batter is smooth and uniform in texture.
  4. Incorporate Boiling Water: Carefully stir in the boiling water until just combined. The batter will be thin, which is normal and results in a moist cake.
  5. Bake Cake Layers: Pour the batter evenly into the prepared cake pans and bake for 30-35 minutes. Test doneness by inserting a toothpick which should come out clean.
  6. Cool Cakes: Remove the cakes from the oven and let them cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
  7. Prepare Frosting: Beat the softened butter until light and creamy. Gradually add powdered sugar and heavy cream while continuing to beat until smooth and fluffy.
  8. Add Flavor and Texture: Mix vanilla extract and crushed Oreo cookies into the frosting until evenly distributed.
  9. Assemble Cake: Spread a layer of frosting on one cake layer, then place the second cake on top and cover the entire cake with the remaining frosting.
  10. Decorate: Garnish with whole Oreo cookies around the cake and drizzle chocolate ganache over the top if desired for extra richness.
  11. Serve: Slice the cake into portions and serve to enjoy the decadent Oreo flavor experience.

Notes

  • Use Dutch-process cocoa powder for a deeper chocolate flavor.
  • Boiling water thins the batter, which helps achieve a moist and tender crumb.
  • For vegan or dairy-free versions, replace eggs with flaxseed or applesauce, milk with almond or soy milk, and heavy cream with coconut cream.
  • Sift the powdered sugar before adding to frosting for a smoother texture.
  • Ensure baking powder and baking soda are fresh for proper rising.
  • Cool cakes completely before frosting to prevent melting.
