Equal quantities of eggs, sr flour, caster sugar and butter. So weigh the eggs first and then measure out the other ingredients to the same. In our case we used 4 eggs which weighed 200g so therefore we had 200g sr flour (with a tsp each of baking powder and bicarb), 200g caster sugar and 200g cheap butter or marg.
Beat sugar and butter together in a mixing bowl.
Sift flour, add to the bowl and whisk.
To that add the eggs and whisk again until you have a smooth batter.
.Divide mixture between your cake cases, to about half full. ours were muffin cases and our quantities made 15 (though I suspect it would have made 20 because some of them were a sneaky bit more than half full, but who am I to tell the 9 year old what to do?). Normal fairy cake cases would be half the mix or twice as many.
Bake in the middle of the oven for about 15 Minutes. (10-12 mins for normal size fairy cakes) 220*c
