Ingredients

Scale

For the Chocolate Cake:

  • 1¾ cups (220g) all-purpose flour
  • ¾ cup (65g) unsweetened cocoa powder
  • 2 cups (400g) granulated sugar
  • 1½ tsp baking powder
  • 1½ tsp baking soda
  • 1 tsp salt
  • 2 eggs
  • 1 cup (240ml) whole milk
  • ½ cup (120ml) vegetable oil
  • 2 tsp vanilla extract
  • 1 cup (240ml) boiling water

For the Chocolate Mousse Frosting:

  • 1½ cups (360ml) heavy cream, cold
  • 200g (7 oz) semi-sweet or dark chocolate, chopped
  • 2 tbsp powdered sugar (optional, for sweetness)
  • 1 tsp vanilla extract

Instructions

  1. Preheat and Prepare Pans: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line them with parchment paper to prevent sticking.
  2. Mix Dry Ingredients: In a large bowl, sift together the all-purpose flour, unsweetened cocoa powder, granulated sugar, baking powder, baking soda, and salt to ensure an even mixture.
  3. Add Wet Ingredients: Add the eggs, whole milk, vegetable oil, and vanilla extract to the dry ingredients. Beat on medium speed for about 2 minutes until the batter is smooth and well combined.
  4. Incorporate Boiling Water: Carefully add the boiling water to the batter. Mix gently; the batter will be thin, but this ensures a moist cake texture.
  5. Bake the Cake: Pour the batter evenly into the prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
  6. Cool the Cakes: Allow the cakes to cool in their pans for 10 minutes, then transfer them onto wire racks to cool completely before frosting.
  7. Melt Chocolate for Frosting: Melt the chopped chocolate in a heatproof bowl over simmering water (double boiler) or in the microwave in 30-second intervals, stirring until smooth. Let it cool to room temperature.
  8. Whip Cream: In a chilled bowl, beat the cold heavy cream until soft peaks form.
  9. Add Flavor and Sweetener: Add vanilla extract and powdered sugar if using, then continue to beat the cream until stiff peaks form.
  10. Combine Chocolate and Whipped Cream: Gently fold the cooled melted chocolate into the whipped cream until the mixture is smooth and mousse-like, being careful not to deflate it.
  11. Assemble the Cake: Place one cake layer on your serving plate and spread a thick layer of the mousse frosting on top.
  12. Add Second Layer and Frost: Place the second cake layer on top and cover the entire cake with the remaining mousse frosting. Smooth the frosting or create swirls for a rustic look. Optionally decorate with chocolate shavings, cocoa powder, or fresh berries.

Notes

  • Chill the frosted cake for at least 30 minutes before serving to allow the mousse frosting to set properly.
  • It is best to consume this mousse frosting cake within 2–3 days. Keep refrigerated to maintain freshness.
  • Using high-quality cocoa powder and chocolate will enhance the flavor deeply.
  • Make sure the chocolate is cooled before folding into the whipped cream to prevent melting the cream.
  • You can substitute whole milk with buttermilk for a tangier taste and softer crumb.
