Step-by-Step Instructions
Step 1: Prepare the Cake Base
- Preheat the oven to 350°F (175°C).
- Grease and line a 9-inch round cake pan with parchment paper.
- In a large mixing bowl, whisk together flour, cocoa powder, granulated sugar, brown sugar, baking soda, baking powder, and salt.
- Add melted butter, eggs, vanilla extract, and buttermilk. Mix until combined.
- Slowly add hot coffee or hot water, stirring until smooth.
- Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool completely before adding the mousse layer.
Step 2: Prepare the Chocolate Mousse
- If using gelatin, dissolve 1 tsp gelatin in 2 tbsp warm water, stirring until completely dissolved.
- Melt the semi-sweet chocolate chips in a microwave or double boiler until smooth.
- In a large mixing bowl, beat heavy cream, powdered sugar, and vanilla extract until soft peaks form.
- Slowly fold the melted chocolate into the whipped cream until smooth.
- If using gelatin, gently fold it into the mousse for added stability.
- Spread the mousse evenly over the cooled cake base.

- Remove from heat and pour over dark chocolate chips.
- Let sit for 1 minute, then stir until smooth and glossy.
- Stir in unsalted butter for extra shine.

Step 4: Assemble and Chill
- Pour the chocolate ganache over the chilled mousse layer, spreading evenly.
- Return the cake to the refrigerator and chill for at least 1 hour to allow the ganache to set.
- Before serving, garnish with chocolate shavings, cocoa powder, or fresh berries.
