Step-by-Step Instructions 📖
Step 1: Prepare the Chocolate Cake
1️⃣ Preheat your oven to 350°F (180°C). Line a 9-inch round cake pan with parchment paper and lightly grease the sides.
2️⃣ In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, and cocoa powder until well combined.
3️⃣ Add the milk, eggs, and vanilla extract, then mix until the batter is smooth and lump-free.
4️⃣ Pour the batter into the prepared cake pan and spread it evenly.
5️⃣ Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
6️⃣ Cool completely before adding the mousse layers.
Step 2: Prepare the Mousse Layers
1️⃣ Melt each type of chocolate (dark, milk, and white) separately using a double boiler or microwave in 20-second intervals. Allow them to cool slightly.
2️⃣ In a large bowl, whip the heavy cream with sugar and vanilla extract until stiff peaks form.
3️⃣ Divide the whipped cream into three equal portions.
4️⃣ Gently fold one portion of whipped cream into the melted dark chocolate, another into the milk chocolate, and the last into the white chocolate. Be careful not to overmix to keep the mousse light and airy.
Step 3: Assemble the Cake
1️⃣ Place the cooled chocolate cake on a serving plate or inside a springform pan for easy layering.
2️⃣ Spread the dark chocolate mousse evenly over the cake base, smoothing the top with a spatula.
3️⃣ Gently spread the milk chocolate mousse over the dark chocolate layer.
4️⃣ Finish with the white chocolate mousse, smoothing the top for a perfect finish.
5️⃣ Refrigerate for 2–4 hours, or until the mousse is completely set.
Step 4: Make the Optional Chocolate Glaze
1️⃣ In a heatproof bowl, melt the chocolate chips and butter using a double boiler or microwave. Stir until smooth.
2️⃣ Once the mousse has set, pour the warm glaze over the top of the cake. Use a spatula to spread it evenly, allowing some to drip down the sides for a dramatic effect.
3️⃣ Refrigerate again for at least 30 minutes to let the glaze set.
Step 5: Serve & Enjoy! 🎂
✨ Garnish with chocolate shavings, cocoa powder, chopped nuts, or fresh berries for an elegant finish.
