This stunning dessert is a Triple-Layer Chocolate Mousse Cake with a mirror-like chocolate ganache glaze. It features moist chocolate sponge layers filled with a light, airy chocolate whipped cream.
The Chocolate Sponge
3 large eggs
100g granulated sugar
75g all-purpose flour
25g unsweetened cocoa powder
1 tsp baking powder
30g melted butter (cooled)
Prep: Preheat your oven to 180°C. Grease and line a rectangular loaf pan or a small square baking tin with parchment paper.
Batter: Beat eggs and sugar for about 5–7 minutes until thick, pale, and tripled in volume.
Dry Ingredients: Sift the flour, cocoa powder, and baking powder together. Gently fold them into the egg mixture using a spatula to keep the air in.
Bake: Fold in the melted butter. Pour the batter into the pan and bake for 20–25 minutes. Let it cool completely, then slice horizontally into three even layers.
The Whipped Chocolate Filling
300ml heavy whipping cream (chilled)
150g milk or dark chocolate (melted and cooled)
2 tbsp powdered sugar
Whip: Beat the heavy cream and powdered sugar until soft peaks form.
Combine: Slowly pour the cooled, melted chocolate into the cream while continuing to whisk until the mixture is stiff and holds its shape.
Assembly: Place the bottom sponge layer down, spread a generous amount of mousse, and repeat. Smooth the sides and top with a thin layer of mousse (crumb coat) and freeze for 30 minutes.
The Chocolate Ganache Glaze
150g dark chocolate (finely chopped)
120ml heavy cream
1 tbsp light corn syrup or honey (for that glossy shine)
Heat: Bring the cream to a simmer (do not boil). Pour it over the chopped chocolate.
Stir: Let it sit for 2 minutes, then stir gently from the center outward until perfectly smooth. Mix in the syrup.
Glaze: Place the chilled cake on a wire rack over a tray. Pour the ganache over the cake in one steady motion, ensuring it covers the top and drips down the sides for a smooth, glass-like finish.
Serving Tip
For those clean, professional slices seen in the image, use a sharp knife dipped in hot water and wiped dry between every single cut. This prevents the mousse from dragging and keeps the layers distinct. Pair it with a cold glass of chocolate milk or a café au lait!
