- Fold the cake flour into the meringue and last fold the cooled melted butter.
- Carefully pour the batter into the prepared pan, smoothing it out into an even layer.
- Bake the cake for 5 minutes, rotate the pan and continue to bake for another 7 minutes or until the center springs back when lightly touched.
- While the cake is baking, place a clean kitchen towel on a work surface.
- Place coco power in a sieve and generously dust the kitchen towel evenly.
- When the cake is done, immediately flip it into the prepare kitchen towel.
- Remove the pan and gently peel off the parchment paper.
- Carefully start rolling the cake from the long end into a tight spiral.
- Keep the cake rolled until it’s completely cooled and really to be filled.
