2 very ripe medium bananas (about 300g in total), peeled
2 eggs
1½ tsp vanilla extract
Method
Preheat the oven to gas 3, 170°C, fan 150°C. Lightly grease a 900g (2lb) loaf tin with butter.
Melt the butter and sugar together in a small saucepan, stirring continuously until the sugar is dissolved. Pour the mixture into a large bowl; leave to cool for 5 minutes.
Meanwhile, sift the flour onto a large plate & use a fork to mash the bananas well.
Beat the eggs, one at a time, into the butter mixture, then fold in the mashed bananas. Stir in the vanilla extract & add the flour gradually.
Scrape the mixture into the loaf tin and bake in the middle of the oven for 45 minutes, until lightly golden and well-risen.
