Ingredients

• 4 large eggs
• 100g (1/2 cup) granulated sugar
• 100g (3/4 cup) all-purpose flour
• 1 teaspoon baking powder
• Pinch of salt
• 50g (1/4 cup) unsalted butter, melted
• 1 teaspoon vanilla extract
• Jam or whipped cream for filling
• Powdered sugar for dusting

Instructions

1. Preheat the oven to 180°C (350°F). Line a baking sheet (30×40 cm) with parchment paper.
2. In a large mixing bowl, beat the eggs and sugar together until the mixture is pale and fluffy.
3. In another bowl, sift together the flour, baking powder, and salt.
4. Gently fold the dry ingredients into the egg mixture, being careful not to deflate the batter.
5. Add the melted butter and vanilla extract, and mix until just combined.
6. Pour the batter into the prepared baking sheet and spread it evenly.
7. Bake in the preheated oven for 12-15 minutes, or until lightly golden and springy to the touch.
8. Once baked, remove from the oven and let it cool in the pan for a few minutes.
9. Turn the cake out onto a clean kitchen towel dusted with powdered sugar. Carefully peel off the parchment paper.
10. Spread your choice of jam or whipped cream evenly over the surface of the cake.
11. Starting from one edge, roll the cake tightly with the towel to form a log shape. Allow it to cool completely in this shape.
12. Once cooled, unfurl the cake and place it on a serving plate. Dust with additional powdered sugar before slicing and serving.
