Ingredients:
- 4 large eggs, separated
- ¾ cup granulated sugar
- ½ teaspoon vanilla extract
- ½ cup all-purpose flour
- ¼ teaspoon baking powder
- Pinch of salt
- Powdered sugar, for dusting
- 1 ½ cups heavy cream, chilled
- ¼ cup powdered sugar
- ½ teaspoon vanilla extract
- ½ cup good-quality strawberry jam
Instructions:
- Preheat oven to 350°F (175°C). Line a 9x13 inch baking sheet with parchment paper.
- In a large bowl, whisk egg yolks and granulated sugar until pale and thick. Add vanilla extract.
- In a separate bowl, whisk together flour, baking powder, and salt.
- Gently fold the dry ingredients into the egg yolk mixture until just combined.
- In a clean, grease-free bowl, beat egg whites until stiff peaks form.
- Gently fold one-third of the beaten egg whites into the yolk mixture, then carefully fold in the remaining egg whites.
- Pour batter into the prepared baking sheet and spread evenly. Bake for 12-15 minutes.
- Lay a clean kitchen towel on a work surface and dust it generously with powdered sugar.
- Once the cake is baked, immediately invert it onto the prepared towel. Gently peel off the parchment paper.
- Starting from one short end, carefully roll the cake up tightly in the towel. Let cool completely in the towel (about 30 minutes).
- In a chilled bowl, beat heavy cream with powdered sugar and vanilla extract until stiff peaks form.
- Gently unroll the cooled cake. Spread evenly with strawberry jam, then top with the whipped cream.
- Carefully re-roll the cake without the towel.
- Wrap the swiss roll in plastic wrap and chill for at least 30 minutes.
- Dust the strawberry swiss roll with additional powdered sugar before slicing and serving.
