Gfcf sponge cake

Olivers birthday cake this year had to be gfcf and nut free due to various children's allergies. So the second receipe I used was
5 eggs beaten till creamy 8-10 mins
1t vanilla essence
1/2 c caster sugar slowly added
Sift
1 1/4 c gf cornflour with
1/2 t gf baking powder
Then fold into the above (but my second attempt founds the it worked better putting the whisk attachment on and going for it.
)
Pour into 20cm round tin
Then bake for 20mins at 150c.
I put them in a square tin and the are now covered in "grass". I'll put a pic up tomorrow once the goals and candles are in place.
