That recipe is really complicated!
Honestly, baking a cake is so simple and you definitely don't need all of those ingredients.
Weigh out 5 eggs in their shell - this should be plenty for two cake tins. (or however many eggs you have or how big you want to cake to be)
Crack eggs into bowl and add the exact same amount of self raising flour, Stork or similar baking margarine (not cheap marg though) and caster sugar.
Mix all together until a nice smooth batter.
Place in greased and grease-proofed baking tins. Bake at about 170 for around twenty minutes until a skewer or toothpick comes out completely clean.
I bake lots of cakes and use this recipe all the time and it always works.
If the cake rises in the middle just chop off the pointy top before you decorate.
