Ingredients
Method
Bake the Cake
- Preheat your oven to 350°F (175°C) and grease your dome-shaped pans.
- In a large bowl, mix the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add the buttermilk, oil, eggs, and vanilla; mix until smooth.
- Stir in the boiling water until well combined.
- Pour the batter into the dome pans and bake for 30-35 minutes.
- Let them cool, then carefully remove from the molds.
Whip Up the Mousse
- Melt the semi-sweet chocolate in a double boiler or microwave.
- In a separate bowl, beat the heavy cream until soft peaks form.
- Add the powdered sugar and vanilla, and mix until combined.
- Fold in the cooled melted chocolate until well blended.
- Chill the mousse while the cake cools.
Assemble the Domes
- Scoop out a small indention from the bottom of each dome cake.
- Fill the indention with mousse, then place the top back on.
- Cover each dome with more mousse and chill for 30 minutes.
Notes
Keep dome cakes in an airtight container in the fridge for 3-4 days. Let ingredients come to room temperature for better texture.
