Method
Preparation
- Preheat your oven to 350°F (175°C) and line a 15x10-inch jelly roll pan with parchment paper.
- In a bowl, mix together the all-purpose flour, cocoa powder, baking powder, and salt.
- In a separate bowl, beat the eggs and granulated sugar until light and fluffy. Add vanilla extract and water.
- Gradually fold the dry ingredients into the egg mixture until just combined.
Baking
- Spread the batter evenly into the prepared pan and bake for 12-15 minutes.
- Allow it to cool briefly, then wrap it in a towel to retain its shape while it cools completely.
Preparation of Filling and Ganache
- Whip the heavy cream with powdered sugar and vanilla extract until stiff peaks form.
- For the ganache, heat 1/2 cup cream until it bubbles, then pour over chopped dark chocolate and stir until smooth.
Assembly
- Unroll the cooled cake gently, spread the whipped cream on top, and re-roll it carefully.
- Drizzle the chocolate ganache on top and refrigerate for about 30 minutes before serving.
Notes
Allow the cake to rest at room temperature before serving for the best flavor and texture. Consider adding fruit purées for a filling variation or crushed hazelnuts for extra texture.
