75g margarine
75g sugar
100g self raising flour
1 egg
1 ripe banana
1) Grease a 2 lb loaf tin and preheat the oven to ~180 C
2) Cream the sugar and margarine
3) Mix in flour
4) Mash a banana with a fork and stir into the mixture.
5) Turn out into the tin and bake for about half an hour
I made 2 quantities to use up the bananas, but I have put the doubled mixture into one tin before and made a bigger loaf. Just leave it in for an extra 5-10 minutes.
Also, I used 2 x 3lb loaf tins this time so it would be easier to halve the mixture (I don't have 2 smaller tins), but I reccomend using th size given in the recipe.
It is tempting to eat it as soon as it comes out of the oven, and while it's really tasty it doesn't cut well; in fact it falls apart. To get decent slices, just let it cool down.
This freezes quite well too, though not for more than 3 months.
