Step 1: Preheat your oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper, making sure the edges are covered, and lightly grease the paper to prevent sticking.

Step 2: In a mixing bowl, beat the eggs with an electric mixer on high speed for about 5 minutes, or until they’re thick, pale, and tripled in volume. This step is key for a light sponge.

Step 3: Gradually add the granulated sugar while mixing, then stir in the vanilla extract. The mixture should look light and foamy.

Step 4: In a separate bowl, sift together the flour, baking powder, and salt. Gently fold the dry ingredients into the egg mixture using a spatula, being careful not to deflate the batter. Go slow and use a figure-eight motion.

Step 5: Pour the batter into the prepared jelly roll pan and spread it evenly with an offset spatula. Tap the pan gently on the counter to release any air bubbles.

Step 6: Bake for 10–12 minutes, or until the cake springs back lightly when touched and the top is golden. Don’t overbake—it dries out quickly!

Step 7: While the cake is baking, lay a clean kitchen towel flat and generously dust it with powdered sugar. This will prevent sticking and help with rolling.

Step 8: When the cake is done, immediately turn it out onto the prepared towel. Peel off the parchment paper gently. While the cake is still warm, carefully roll it up in the towel, starting from the short end. Let it cool completely while rolled—this helps “train” the cake to hold its shape.

Step 9: Meanwhile, make the filling. Whip the cold cream with powdered sugar and vanilla extract until stiff peaks form. Gently fold in the chopped strawberries. Refrigerate until ready to use.

Step 10: Once the cake has cooled, carefully unroll it. Spread the strawberry cream filling evenly across the surface, leaving about 1/2 inch border around the edges.

Step 11: Roll the cake back up tightly, this time without the towel. Wrap it in plastic wrap and chill for at least 30 minutes to help it set and slice cleanly.

Step 12: Before serving, dust with powdered sugar and garnish with fresh strawberries or whipped cream if desired. Slice and serve—each piece should reveal that gorgeous spiral inside!
