The following recipe can be used as a basis for a Victoria Sponge, Marble Cake, Sultana Cake, Madiera Cake, Chocolate Sponge Cake and many more.
Firstly, you will need a mixing bowl, a wooden spoon (or an electric whisk if you are lucky enough to own one!), an oven, a cake tin, a sieve and a cooling rack.
So that's the technical stuff out of the way. Food wise, you will need 75g/3oz of soft margarine and 75g/3oz of butter, 200g/8oz of self-raising flour, 175g/7oz of caster sugar, vanilla essence (optional) 3 eggs and 1 teaspoon of baking powder.
Preheat the oven to gas mark 3/170°/325°F. Beat the margarine and butter together with the electric whisk/wooden spoon until it's smooth. Add the sugar gradually at one tablespoon full a time to make the mixture light and fluffy. Stir in any essence or food colouring you want to use. Whisk the eggs in a separate bowl and then keep adding them to the cake mixture a spoonful at a time.
Grease the cake tin and pour the cake mixture into it. Bake for 45-50 minutes at gas mark 4/350F/180C. If further cooking is required then reduce the heat to gas mark 3/325°F/170°C.
To check if the cake is ready, make a fingerprint into the middle of the cake. If it bounces back into shape it is ready!
Leave to cool for 15 minutes, add any icing or decorations if you want...and dig in!
