[hotcrossbunny]

Hi

Have ordered a cake topper for my dd's birthday cake and then realised I don't have a recipe for a cake that big! I have no idea how to calculate it myself either

Please lovely MNers, can you sort me out???? I'm thinking plain and simple sponge, traybake type thing. I'm not planning on filling it...

No-one?

can you trim the cake topper at all?
i can give you a recipe for 8 x 12inch cake

Thank you! I'd love that recipe please

ok it's a plain vanilla sponge but is nice and light and easy to shape
160c/325f/gas 3

350g butter/marg
350g caster sugar
6 eggs
350g SR flour
3 tsp baking powder
12 drops vanilla flavouring

bake for approx 1 hour
store the cake in an airtight container or wrap it in foil leaving it for at least 12 hours before cutting
