🍳 STEP-BY-STEP COOKING PROCEDURE
STEP 1: MAKE THE CAKE BASE
- Preheat oven to 180°C (350°F).
- Grease and line an 8-inch round cake pan.
- In a mixing bowl, combine:
- Flour
- Sugar
- Cocoa powder
- Baking powder
- Baking soda
- Salt
- Add egg, milk, oil, and vanilla. Mix until smooth.
- Add hot water/coffee and gently whisk — the batter will be thin.
- Pour into the pan and bake 25–30 minutes or until a toothpick comes out clean.
- Cool completely, then place the cake in a cake ring/springform tin.
STEP 2: PREPARE THE CHOCOLATE MOUSSE
Bloom the Gelatin
- Combine gelatin with ¼ cup warm water.
- Let it sit for 5 minutes to thicken.
Make the Chocolate Base
- Melt chocolate + butter using a double boiler or microwave in 20-second intervals.
- Add vanilla extract and mix.
- Add bloomed gelatin into the warm melted chocolate and mix well until smooth.
Whip the Cream
- In a chilled bowl, whip the heavy cream until soft peaks form.
- Add sugar if you prefer sweeter mousse.
Combine
- Add ¼ of the whipped cream into the chocolate mixture and mix fast (temp adjustment).
- Fold the remaining whipped cream slowly using a spatula until smooth and airy.
STEP 3: ASSEMBLE THE CAKE
- Pour the prepared chocolate mousse over the cooled cake base in the cake ring.
- Smooth the top with a spatula.
- Refrigerate at least 4 hours, or overnight for best results.
STEP 4: PREPARE GANACHE (OPTIONAL)
- Heat cream until steaming (not boiling).
- Pour over chopped chocolate.
- Let sit 1 minute, then stir until smooth and glossy.
- Add butter for shine.
- Let the ganache cool slightly before pouring over the cold mousse layer.
STEP 5: CHILL & SERVE
- Chill the cake for 30 more minutes after adding the ganache.
- Gently remove cake ring.
- Decorate with chocolate curls, cocoa powder, berries, or whipped cream.
⭐ PRO TIPS FOR PERFECT RESULTS
- Use high-quality chocolate for the mousse; it affects flavor massively.
- Do not pour hot ganache over mousse — it may melt.
- Whip cream to soft peaks, not stiff — this keeps mousse airy.
- For a no-gelatin version, use stabilized whipped cream or mascarpone.
