Line a 2lb loaf tin, and preheat oven to 160C/325F/gas mark 3
Place all the ingredients in a bowl and beat until smooth. This will only take 2 minutes with a hand mixer, a little longer with a wooden spoon.
Spoon into the prepared tin and smooth level. Bake for 1 hour, or until golden and well risen.
Cool on a rack before storing in an airtight container. Leave for 24 hours before cutting.
