What you need:
150 g caster sugar
1 tsp vanilla extract
1 egg, beaten
2 very ripe bananas, mashed
190g self-raising flour
How you do it:
Grease and line a 2lb loaf tin. Melt butter, sugar and vanilla in a saucepan over a medium heat.
Remove from the heat and add the mashed bananas, mix well.
Stir in the flour and the milk.
Pour into the prepared tin, sprinkle with a tablespoon of demerara sugar to give a crunchy topping (if you like - Becky did).
Bake at 150C fan oven (or 170C regular, gas mark 3) for 35 minutes, until a skewer comes out clean. Leave to cool and enjoy with a cup of tea.
