Preheat the oven to 180 degrees C

Grease and line a small loaf tin

Beat the eggs and sugar until pale, then add the vanilla and butter and mix

Sift the dry ingredients into the bowl with the eggs and whisk until smooth

Pour into the loaf tin and bake for 10 – 15 minutes until the top is firm with a few cracks

A cake skewer inserted into the middle should come out with a few crumbs stuck to it

Allow to cool

Eat out of the tin or cut into squares
