jennyfenny, at the risk of being repetitive and boring, I'll post this again (have posted it several times).I use this recipe for everything requiring a sponge.just changing the shape and size of the pan :)

ABSOLUTELY BEST-EVER SPONGE
Assemble all ingredients
Have eggs at room temperature
Sift 1/2 cup cornflour
2 teaspoons ordinary flour
1 teaspoon baking powder
Lightly grease sponge roll pan and put baking paper in the bottom
Separate 3 eggs
Beat whites till soft peaks form
Slowly add 1/2 cup caster sugar, beating all the time
Add yolks and beat till rich mix
Add all sifted dry ingredients and stir to combine
Pour mix into pan and drop sharply onto bench
Bake 180*C for 15 minutes
Drop again on bench after removing from oven
Rest it for 5-10 minutes before removing
Cut in half, fill with fruit and whipped cream and place other half on top
