Description

A decadent dessert with a rich dark chocolate cake paired with smooth milk chocolate buttercream, offering the perfect balance of chocolate depth and sweetness.


Ingredients

  1. For the dark chocolate cake:
    • 1 1/2 cups all-purpose flour
    • 1 cup unsweetened cocoa powder
    • 1 1/2 tsp baking powder
    • 1 tsp baking soda
    • 1/2 tsp salt
    • 3/4 cup granulated sugar
    • 3/4 cup brown sugar
    • 3 large eggs, at room temperature
    • 1 cup whole milk
    • 1/2 cup vegetable oil
    • 1 tsp vanilla extract
    • 1/2 cup hot water
    • 4 oz dark chocolate, chopped (or dark chocolate chips)
  2. For the milk chocolate buttercream:
    • 1 cup unsalted butter, softened
    • 3 cups powdered sugar
    • 1/2 cup unsweetened cocoa powder
    • 1/2 cup milk chocolate chips, melted
    • 2 tsp vanilla extract
    • 12 tbsp heavy cream (as needed for consistency)

Instructions

  1. For the Dark Chocolate Cake:
    1. Preheat your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
    2. In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
    3. In a large bowl, beat together the granulated sugar, brown sugar, eggs, milk, vegetable oil, and vanilla extract until smooth and well combined.
    4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
    5. In a small bowl, microwave the chopped dark chocolate in 20-second intervals, stirring in between, until fully melted and smooth. Once melted, mix the chocolate into the cake batter.
    6. Slowly add the hot water to the batter, mixing until smooth. The batter will be thin, but that’s okay—it creates a moist cake.
    7. Divide the batter evenly between the two prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then remove from the pans and allow to cool completely on a wire rack.
  2. For the Milk Chocolate Buttercream:
    1. In a large bowl, beat the softened butter with an electric mixer until light and fluffy, about 3-4 minutes.
    2. Gradually add the powdered sugar and cocoa powder, beating on low speed to combine. Once combined, increase the speed and continue beating until smooth.
    3. Mix in the melted milk chocolate and vanilla extract until fully incorporated.
    4. If the buttercream is too thick, add 1 tablespoon of heavy cream at a time until the buttercream reaches your desired consistency.
  3. Assembling the Cake:
    1. Once the cake layers are completely cool, place the first layer on a serving plate. Spread a generous layer of the milk chocolate buttercream on top of the first cake layer.
    2. Place the second cake layer on top of the frosted cake. Frost the top and sides of the cake with the remaining milk chocolate buttercream.
    3. Optionally, garnish the cake with chocolate shavings, cocoa powder, or fresh berries for a decorative touch.
    4. Allow the cake to set in the refrigerator for 30 minutes to firm up the buttercream. Slice and serve!

Notes

  • For a more intense chocolate flavor, use dark chocolate in the buttercream instead of milk chocolate.
  • If desired, add a ganache drizzle over the cake for added richness.
  • To make the cake gluten-free, use a gluten-free flour blend and ensure all other ingredients are gluten-free.
