Ingredients

Scale
  • 1 ¾ cups (220g) all-purpose flour
  • ¾ cup (75g) unsweetened Dutch-processed cocoa powder
  • 1 ½ tsp baking powder
  • 1 ½ tsp baking soda
  • ½ tsp salt
  • 1 ½ cups (300g) granulated white sugar
  • 2 large eggs, room temperature
  • 1 cup (240ml) buttermilk (or dairy-free milk with vinegar)
  • ½ cup (120ml) vegetable oil
  • 2 tsp vanilla extract
  • 1 cup (240ml) hot brewed coffee (optional but recommended)
  • 8 oz (225g) bittersweet chocolate, chopped
  • 2 cups (480ml) heavy cream, cold
  • ¼ cup (30g) powdered sugar
  • 1 tsp vanilla extract
  • 3 egg whites, room temperature (optional for extra fluff)
  • Chocolate shavings or curls (optional garnish)
  • Cocoa powder dusting (optional garnish)
  • Fresh berries (raspberries or strawberries, optional garnish)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line with parchment paper.
  2. Sift together flour, cocoa powder, baking powder, baking soda, and salt in a large bowl. Set aside.
  3. In another bowl, whisk sugar, eggs, buttermilk, vegetable oil, and vanilla extract until smooth and slightly fluffy (about 2 minutes).
  4. Slowly add dry ingredients to wet ingredients, mixing gently but thoroughly to avoid overmixing.
  5. Stir in hot brewed coffee carefully; batter will be slightly runny.
  6. Divide batter evenly between prepared pans and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Start checking at 28 minutes.
  7. Cool cakes in pans for 10 minutes, then turn out onto a cooling rack and cool completely (about 1 hour).
  8. Melt chopped bittersweet chocolate over a double boiler or microwave in 30-second bursts, stirring until smooth. Let cool slightly.
  9. Whip cold heavy cream with powdered sugar and vanilla extract in a chilled bowl until soft peaks form.
  10. Optionally, beat egg whites until stiff peaks form and gently fold into whipped cream for extra lightness.
  11. Fold melted chocolate gently into whipped cream mixture to keep mousse airy and smooth.
  12. Place one cake layer on serving plate. Spread half of the mousse over it with an offset spatula.
  13. Top with second cake layer and spread remaining mousse on top and sides. Smooth or create soft peaks.
  14. Refrigerate for at least 4 hours, preferably overnight, to allow mousse to set and flavors to meld.
  15. Before serving, garnish with chocolate shavings, cocoa powder dusting, or fresh berries as desired.

Notes

Use room temperature eggs for a tender crumb. Do not overmix batter to keep cake light. Fold mousse gently to maintain airiness. Chill cake at least 4 hours or overnight for best texture and flavor. Coffee enhances chocolate flavor but is optional. For gluten-free, substitute almond flour (expect denser texture). For dairy-free, use coconut cream and dairy-free chocolate. For vegan, replace eggs with aquafaba and use plant-based milk.
