# How To Make It:
01 - Preheat oven to 350°F. Grease a 9-inch springform pan and line the base with parchment paper.
02 - Sift together flour, cocoa powder, baking powder, and salt in a medium bowl.
03 - Beat eggs and sugar with an electric mixer until pale and tripled in volume, approximately 5 minutes.
04 - Gently fold dry ingredients into egg mixture. Drizzle in milk, oil, and vanilla; mix until just combined.
05 - Pour batter into prepared pan and bake for 18-20 minutes until a toothpick inserted in center comes out clean. Cool completely in pan.
06 - Melt dark chocolate in a heatproof bowl over simmering water, stirring until smooth. Cool slightly.
07 - Combine sugar and water in a small saucepan. Heat until sugar dissolves and mixture simmers.
08 - Beat egg yolks in a separate bowl. Gradually pour hot syrup into yolks while whisking constantly until mixture is pale and thick.
09 - Stir melted chocolate and vanilla extract into egg yolk mixture. Add a pinch of salt.
10 - Whip cold heavy cream in a clean bowl until soft peaks form.
11 - Fold one-third of whipped cream into chocolate mixture to lighten. Gently fold in remaining cream until smooth.
12 - Place cooled sponge on serving platter. Reassemble springform pan ring around sponge. Pour mousse over sponge, smoothing the top. Refrigerate for at least 4 hours until set.
13 - Heat cream until simmering. Pour over chopped chocolate and butter. Let stand for 1 minute, then stir until glossy and smooth. Cool for 10 minutes.
14 - Remove cake from pan. Pour glaze over mousse layer, allowing it to drip down the sides. Smooth top with spatula. Chill for 30 minutes before serving.
# Handy Tips:
01 -
- The texture contrast between airy sponge, silky mousse, and snappy glaze makes every forkful an experience
- It looks like something from a fancy patisserie but comes together with patience and basic techniques
02 -
- The hot sugar syrup must be poured slowly into the yolks while whisking constantly to prevent scrambling
- Over whipping the cream makes it grainy and harder to fold into the chocolate smoothly
- The glaze needs to cool slightly but still be pourable, or it will set too quickly and look streaky
03 -
- Brush the cooled sponge with coffee syrup before adding the mousse for deeper flavor
- If your kitchen is warm, chill the springform pan for 10 minutes before pouring the glaze
