How to Make Triple Chocolate Mousse Cake
Step 1: Make the Chocolate Cake Base
- Preheat and Prepare – Preheat your oven to 350°F (175°C). Grease and line an 8-inch springform pan with parchment paper.
- Mix Dry Ingredients – In a bowl, whisk together the flour, cocoa powder, baking powder, and salt.
- Prepare Wet Ingredients – In another bowl, whisk the melted butter and sugar until smooth. Add the egg, milk, and vanilla extract, mixing until combined.
- Combine and Bake – Gradually fold the dry ingredients into the wet ingredients. Pour the batter into the prepared pan and bake for about 15-18 minutes, or until a toothpick inserted in the center comes out clean. Let it cool completely in the pan.
Step 2: Make the Milk Chocolate Mousse
- Melt the Chocolate – In a heatproof bowl, melt the milk chocolate using a double boiler or microwave in 20-second intervals, stirring until smooth. Set aside.
- Prepare Gelatin – In a small bowl, sprinkle the gelatin over water and let it bloom for 5 minutes. Then, microwave for 5-10 seconds until dissolved.
- Whip the Cream – In a separate bowl, whip the heavy cream until soft peaks form.
- Combine – Stir the dissolved gelatin into the melted chocolate. Then, gently fold in the whipped cream until smooth.
- Layer It – Pour the milk chocolate mousse over the cooled cake base, smoothing it out. Refrigerate for at least 30 minutes to set.
Step 3: Make the White Chocolate Mousse
- Melt the White Chocolate – Follow the same process as before, melting the white chocolate in a double boiler or microwave.
- Prepare Gelatin – Bloom the gelatin in water, then dissolve it by microwaving for a few seconds.
- Whip the Cream – Whip the heavy cream until soft peaks form.
- Combine – Stir the gelatin into the melted white chocolate, then gently fold in the whipped cream.
- Final Layer – Spread the white chocolate mousse over the milk chocolate layer, smoothing the top.
Step 4: Chill and Serve
- Refrigerate – Let the entire cake chill in the fridge for at least 4-6 hours, or preferably overnight, to ensure it sets properly.
- Garnish and Enjoy – Once set, carefully remove the cake from the pan. Garnish with chocolate shavings, cocoa powder, or fresh berries. Slice and serve chilled!
Helpful Tips
- Use High-Quality Chocolate – Since chocolate is the star of this cake, using good quality chocolate makes a big difference in taste and texture.
- Let Each Layer Set – Be patient and allow each mousse layer to set properly before adding the next. This helps maintain clean layers.
- Smooth Mousse Texture – Fold the whipped cream into the melted chocolate gently to keep the mousse light and airy.
- Chill Overnight for Best Results – While a few hours in the fridge will work, letting the cake chill overnight ensures a firm, well-set texture.
