- Why didn't the sponge cake rise?
- Chestnuts make the batter heavy, so it's especially important to whip the egg whites until stiff peaks form and fold them in gently to keep the air trapped.
- The cream is too soft.
- The heavy cream must be very cold when whipped. If it's still too soft, you can use a whip stabilizer (like Whip It).

Instructions
Preheat the oven to 350°F (180°C). Line the bottom of the springform pan with parchment paper.
Whisk the egg yolks with the sugar until foamy, then mix in the melted butter, milk, and 3.5 oz (100g) of the mashed chestnut paste. Mix until smooth.
Sift in the flour mixed with the baking powder and stir to combine.
Whip the egg whites with a pinch of salt until stiff peaks form. Gently fold into the batter in several batches.
Pour into the pan and bake for 30-35 minutes (test with a toothpick). Let it cool completely on a wire rack.
For the filling, whip the cold heavy cream until stiff, then gently fold in the remaining 5.5 oz (150g) of mashed chestnut paste.
Slice the sponge cake in half horizontally. Fill with 2/3 of the cream. Use the remaining cream to frost the top and sides. Drizzle with melted chocolate.
