Ingredients:
For the Cake:
- 4 large eggs
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 1/4 cup unsweetened cocoa powder
- 1 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup milk
For the Filling:
- 1 1/2 cups heavy cream
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
For the Ganache:
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy cream
Instructions:
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 10×15-inch jelly roll pan and line it with parchment paper, leaving an overhang on the longer sides.
- Make the Cake Batter:
- In a large bowl, beat the eggs until they are thick and pale. Add the granulated sugar and vanilla extract, continuing to beat until well combined.
- Sift together the cocoa powder, flour, baking powder, and salt. Gradually add this dry mixture to the egg mixture, alternating with the milk. Begin and end with the dry ingredients, mixing just until combined.
- Bake the Cake:
- Pour the batter into the prepared pan, spreading it evenly. Bake in the preheated oven for 15-18 minutes or until the cake springs back when touched.
- Prepare the Filling:
- While the cake is baking, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Set aside.
- Roll the Cake:
- Once the cake is baked, immediately loosen the edges with a knife. Dust the top of the cake with powdered sugar and place a clean kitchen towel over it.
- Invert the cake onto the towel and peel off the parchment paper. Starting from the shorter edge, gently roll the cake along with the towel. Allow it to cool completely.
- Fill the Cake:
- Carefully unroll the cooled cake and spread the whipped cream evenly over the surface. Re-roll the cake without the towel. Place it seam side down on a serving platter.
- Make the Ganache:
- In a heatproof bowl, combine the chocolate chips and heavy cream. Microwave in short bursts or use a double boiler until the chocolate is melted and smooth. Allow it to cool slightly.
- Finish with Ganache:
- Pour the ganache over the rolled cake, spreading it evenly with a spatula. Let it set for a few minutes.
- Serve and Enjoy:
- Slice your chocolate Swiss roll cake into delectable rounds, and watch it disappear faster than you can say, “Sweet satisfaction!”
