We've used this one for years here in the U.S.
3 ripe or overripe bananas, mashed
1 cup sugar
1 egg
4 TBL butter, melted
1 tsp vanilla
1 1/2 cups flour
1 tsp baking soda
1/2 tsp salt
Preheat oven to 325� (F). Grease & flour an 8" loaf pan. In a large bowl, combine the mashed bananas, sugar, egg, melted butter & vanilla. Beat until thoroughly mixed. In a separate bowl, whisk together the flour, baking soda & salt. Stir the flour mixture into the banana mxiture just until blended. Pour & scrape the batter into the prepared (sprayed if it's a non-stick loaf pan) pan. Bake 1 hour or until a toothpick inserted near the center of the loaf comes out clean. Allow the bread to cool in the pan 10 minutes, then turn out onto a rack
(If you have more bananas, freeze them with the skins on. Just put them in a freezer bag. They'll keep a long time eventhough the skins turn black)
