Sponge cake recipe without egg yolks?

Is there a spongecake recipe out there that is only made with egg


whites? can it even be done? I would assume the cake would be to light and not dense enough to do more then one layer on top of each


other. I have a good recipe for spongecake but it requires egg yolks. Could I maybe just double up on the egg


whites to replace the yolks for the recipe? Answers would be appreciated please and thanks!Sponge cake recipe without egg yolks?
