All-In-One Sponge Cake - cooking recipe

Ingredients

3/4 cup butter or 3/4 cup margarine, needs to be soft
1 cup caster sugar or 1 cup fine sugar
3 eggs, beaten
1 1/2 cups sifted self-raising flour
2 teaspoons baking powder

Preparation

Preheat oven to 350 degrees F (325F if you know your oven is really hot).
Measure out all the ingredients, put in to a large bowl and beat until well blended (I use an electric mixer but you can do this by hand).
Divide this between the two tins; level out and bake in the oven for approx 30-35 minutes, until well risen and the top of the sponges spring back when lightly pressed with your finger.
Leave them to cool for 5 minutes in the tin before you turn them out; remove the paper and let them completely cool on a cake rack.
When cold, sandwich them together with your favorite filling.
Sprinkle caster or powdered sugar on the top.
