Instructions

Preheat oven to 375°F (190°C) and line a 10×15-inch jellyroll pan with parchment paper without greasing the sides.
In a chilled bowl, whip heavy cream, 1/2 cup confectioners’ sugar, 1/2 cup cocoa powder, and 1 teaspoon vanilla to stiff peaks, then refrigerate immediately.
Beat the egg yolks with 1/2 cup granulated sugar for 3 to 5 minutes until thick and pale; sift in 1/3 cup cocoa, 1.5 teaspoons vanilla, and salt, then blend on low.
In a clean bowl, whip egg whites to soft peaks, then gradually add 1/4 cup granulated sugar and whip until stiff and glossy.
Stir one-third of the egg whites into the yolk mixture to lighten it, then gently fold in the remaining whites until no streaks remain.
Spread the batter into the pan with an offset spatula and bake for 10 to 12 minutes until the surface springs back.
Immediately invert the warm cake onto a kitchen towel dusted with confectioners’ sugar, peel off parchment, and roll the cake and towel together from the short edge; cool for 30 minutes.
Unroll the cake, spread the chilled filling to within 1 inch of the edges, re-roll tightly, and refrigerate seam-side down for at least 60 minutes before serving.

Notes

For the most successful roll, ensure your kitchen towel is generously dusted with confectioners’ sugar while the cake is still piping hot from the oven. If your environment is particularly dry, you can place a slightly damp towel over the cake during the 30-minute cooling phase to retain maximum flexibility in the sponge proteins.
