Method
- Preheat your oven to 350°F (175°C). Line a 10×15-inch baking sheet with parchment paper and lightly grease it to prevent sticking.
- In a medium bowl, sift together the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Set this mixture aside.
- In a large bowl, whisk the four large eggs and granulated sugar on high speed for about 5 minutes until the mixture becomes thick, pale, and creamy. Add 1 teaspoon of vanilla extract and mix well to combine.
- Gently fold the dry ingredients into the egg mixture, taking care not to overmix to retain the airiness of the batter.
- Pour the batter evenly onto the prepared baking sheet and bake for 10-12 minutes until the cake springs back when lightly touched, indicating it is done.
- While warm, carefully lift the parchment paper and roll the cake into a log shape starting from one short end to the other. Allow it to cool completely while rolled, which helps the cake keep its shape.
- In a medium bowl, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form, creating a light and fluffy filling.
- Unroll the cooled cake gently and spread the whipped cream filling evenly across the surface. Re-roll the cake tightly, peeling away the parchment paper gradually as you roll.
- Heat the ¼ cup heavy cream until just boiling and pour it over the chopped dark chocolate. Let it sit for a minute to melt, then stir until smooth and glossy.
- Pour the ganache evenly over the rolled cake if using. Chill the cake in the refrigerator for at least 30 minutes before slicing and serving for the best texture and flavor integration.
Notes
For a perfect roll, ensure the cake is still warm when you first roll it. Chilling the cake is crucial for setting the filling and ganache, making it easier to slice cleanly. This recipe can be made ahead of time and stored in the refrigerator for up to 2-3 days.
