Ingredients
1 3/4 cups all-purpose flour
3/4 cup cocoa powder
1 1/2 tsp baking powder
1 1/2 tsp baking soda
1/2 tsp salt
2 cups granulated sugar
2 eggs

1 cup buttermilk
1 cup hot coffee
8 oz semi-sweet chocolate
2 cups heavy whipping cream
1/4 cup powdered sugar
1 tsp gelatin
2 tbsp water

Instructions
Preheat the oven to 350°F (175°C). Grease and line a round cake pan with parchment paper.
In a large bowl, whisk together the flour, cocoa powder, baking powder, baking soda, salt, and sugar.
Add the eggs, vegetable oil, vanilla extract, and buttermilk. Mix until smooth.
Slowly stir in the hot coffee until the batter is fully combined.
Pour the batter into the prepared cake pan and bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely before preparing the mousse layer.
Melt the semi-sweet chocolate and let it cool slightly.
In a small bowl, sprinkle gelatin over water and let it bloom for several minutes.
Heat the gelatin mixture gently until dissolved.
In a mixing bowl, whip the heavy cream with powdered sugar until soft peaks form.
Stir the dissolved gelatin into the melted chocolate.
Fold the whipped cream gently into the chocolate mixture until smooth and airy.
Place the cooled cake layer into a springform pan and spread the mousse evenly over the top.
Refrigerate for at least 4 hours or until the mousse is fully set.
Garnish with chocolate shavings or cocoa powder before serving.
Notes
Add raspberry jam between the cake and mousse for a fruity contrast.
Dark chocolate can be used for a richer and less sweet flavor.
Espresso powder enhances the chocolate intensity.
Fresh berries and whipped cream make excellent toppings.
