Spread the batter evenly in your pan and bake for 12-15 minutes. The top should spring back when lightly touched.

Lay out a towel and sprinkle it with powdered sugar. Flip the hot cake onto the towel, peel off the parchment, and roll it up with the towel inside. Leave it to cool completely.

Unroll your cooled cake carefully, spread the lemon cream filling over it, and roll it back up (without the towel this time). Chill for at least an hour. Sprinkle a little powdered sugar on top before serving.
