Step 1:
Bake a Vanilla sponge in a standard jelly roll pan and sift two  tablespoons of icing sugar onto a clean towel. When the cake is out of the oven, immediately turn it out onto the towel. Carefully peel back the parchment paper.

Step 2:
Use the towel to help roll the cake up into a log. Place it, seam-side down, on a wire rack to cool for a few minutes.

Step 3:
Have your fillings ready, then carefully unroll the cake. Do not try to make it lie flat – this might cause the cake to crack. Spread the cake with jam and whipped cream, or any other desired fillings.

Step 4:
Use the towel to again roll the cake back into a log and dust with icing sugar to serve.
