Ingredients

Scale

Dry Ingredients

  • 2 cups all-purpose flour (Gluten-free option available)
  • 3/4 cup unsweetened cocoa powder (Dutch-process for enhanced flavor)
  • 2 cups granulated sugar (Brown sugar can add moisture)
  • 1 tbsp baking powder (ensure freshness)
  • 1 tbsp baking soda
  • 1 tsp salt (a pinch to elevate flavor)

Wet Ingredients

  • 2 large eggs (or flaxseed/applesauce for vegan substitute)
  • 1 cup whole milk (almond or soy milk for lactose intolerance)
  • 1/2 cup vegetable oil (melted coconut oil alternative)
  • 2 tsp vanilla extract (pure preferred)
  • 1 cup boiling water

Frosting Ingredients

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 1/4 cup heavy cream (or coconut cream for dairy-free)
  • 2 tsp vanilla extract
  • 1 cup crushed Oreo cookies (try different flavors for variation)

Decoration

  • 6 whole Oreo cookies for topping
  • 1/2 cup chocolate ganache (optional drizzle)

Instructions

  1. Preheat Oven and Prepare Pans: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans thoroughly to prevent sticking.
  2. Mix Dry Ingredients: In a large mixing bowl, whisk together all dry ingredients — the flour, cocoa powder, granulated sugar, baking powder, baking soda, and salt — until the mixture is smooth and lump-free.
  3. Combine Wet Ingredients: Add eggs, milk, vegetable oil, and vanilla extract to the dry mixture. Use an electric mixer to blend everything until the batter is smooth and homogenous.
  4. Add Boiling Water: Gradually stir in the boiling water carefully until fully combined; this will create a thin batter necessary for a moist cake texture.
  5. Pour and Bake: Evenly divide the batter between the two prepared cake pans. Place them in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  6. Cool Cakes: Allow the cakes to cool in their pans for about 10 minutes, then transfer them to wire racks to cool completely to room temperature.
  7. Make Frosting: Beat the softened butter until light and creamy. Gradually incorporate the sifted powdered sugar and heavy cream, beating continuously. Add vanilla extract and fold in the crushed Oreo cookies evenly throughout the frosting.
  8. Assemble Cake: Place one cake layer on your serving plate and spread a generous amount of Oreo frosting on top. Place the second layer over it and continue frosting the top and sides of the entire cake smoothly and evenly.
  9. Decorate: Arrange six whole Oreo cookies on top of the cake for decoration. Optionally, drizzle chocolate ganache over the top for an extra touch of indulgence.
  10. Serve: Slice the cake into portions and serve immediately or refrigerate until ready to enjoy.

Notes

  • For a vegan version, substitute eggs with flaxseed or applesauce and use plant-based milk and coconut cream.
  • Ensure baking powder and baking soda are fresh for proper rising.
  • Use Dutch-process cocoa powder for a richer chocolate flavor.
  • Sifting powdered sugar prevents lumps in the frosting.
  • Boiling water helps to enhance the cocoa flavor and makes the batter thin for moist cake layers.
  • Allowing the cake to cool completely before frosting prevents melting and sliding.
  • Chocolate ganache is optional but adds a glossy finish and extra chocolate depth.
