Its easy to increase the mix too if you need more since its a 2:1 ratio
2oz each of the flour, sugar & margarine per 1 egg
You'll need
4 oz Self Raising Flour
4 oz Caster Sugar
4 oz Margarine
2 large Eggs
1 tsp Vanilla Extract
How to make
Pre-heat your oven to 180c and grease a cake tin (or line a muffin tin with cases).
You'll need to cream the butter and sugar together until its light and fluffy.
One at a time, you'll need to add the eggs and allow to mix in between each one. This is where i love my standing mixer as makes life a lot easier.
Gradually add the flour a little at a time and mix until its all combined nicely.
