Instructions
Preparation
- Preheat your oven to 350°F (175°C).
- Grease and flour a 9-inch round cake pan.
- In a mixing bowl, cream 1/2 cup of butter and 1 cup of sugar together until light and fluffy.
- Add in 2 eggs and 1 tsp of vanilla extract, mixing until combined.
- Sift together 1/2 cup of cocoa powder, 1 cup of flour, 1 tsp of baking soda, and 1/2 tsp of salt in another bowl.
- Gradually mix the dry ingredients into the wet ingredients, alternating with 1/2 cup of buttermilk and 1/2 cup of hot coffee until the batter is smooth.
Cooking
- Pour the cake batter into your prepared pan.
- Bake for about 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
- While the cake cools, melt 8 oz of bittersweet chocolate with 2 tbsp of butter over a double boiler or in the microwave.
- In another bowl, whip the 3 egg whites until soft peaks form, then gradually add 1/4 cup of sugar until you reach stiff peaks.
Assembly

- In a separate bowl, whip 1 cup of heavy cream until stiff peaks form. Fold this into the chocolate mixture.
- Once the cake has completely cooled, slice it in half horizontally to create two layers.
- Spread a layer of the chocolate mousse on the bottom layer and then place the top layer back on.
- Spread the remaining mousse on top and around the sides of the cake.
- Chill in the refrigerator for at least 2 hours before serving.
Notes
Use room temperature ingredients for better mixing. Don't overmix to keep your mousse light and airy. Optional: Mix a teaspoon of espresso powder into your batter for extra flavor.
