Ingredients:
- 4 large eggs, separated (US and Metric)
- ¾ cup (150g) granulated sugar, divided (US and Metric)
- ½ cup (60g) all-purpose flour (US and Metric)
- ¼ cup (25g) unsweetened cocoa powder (US and Metric)
- 1 teaspoon vanilla extract (5ml) (US and Metric)
- Pinch of salt (US and Metric)
- Powdered sugar, for dusting (US and Metric)
- 1 cup (240ml) heavy cream (US and Metric)
- ¼ cup (30g) powdered sugar (US and Metric)
- ½ teaspoon vanilla extract (2.5ml) (US and Metric)
Instructions:
- Preheat oven to 350°F (175°C). Grease and line the baking pan with parchment paper, leaving an overhang on the sides.
- In a large bowl, whisk together egg yolks and half of the granulated sugar until pale and thick. Add vanilla extract.
- In a separate bowl, sift together flour, cocoa powder, and salt.
- In a clean, dry bowl, beat egg whites with an electric mixer until soft peaks form. Gradually add the remaining granulated sugar and continue beating until stiff, glossy peaks form. Avoid over-beating.
- Gently fold the dry ingredients into the egg yolk mixture. Then, gently fold in the beaten egg whites in two additions, being careful not to deflate the mixture. Maintain airiness.
- Pour the batter into the prepared baking pan and spread evenly. Bake for 12-15 minutes, or until the cake springs back lightly when touched. Don't over-bake!
- Immediately invert the cake onto a clean kitchen towel generously dusted with powdered sugar. Peel off the parchment paper.
- Starting from one short end, roll the cake up tightly with the towel inside. Let cool completely in the towel. This is crucial for the cake to hold its shape!
- In a chilled bowl, beat heavy cream with powdered sugar and vanilla extract until stiff peaks form. Avoid over-beating, or you'll get butter!
- Gently unroll the cooled cake. Spread the whipped cream filling evenly over the surface.
- Carefully re-roll the cake without the towel. Wrap tightly in plastic wrap and chill for at least 30 minutes to allow the filling to set.
- Before serving, dust the roll with additional powdered sugar and slice into desired thickness. The perfect Chocolate Swiss Roll Cake.
