Heat the oven to 175C and line a 23 x 13 cm loaf pan with baking paper.
Mash the peeled bananas with a fork until almost smooth.
Stir in the melted butter, then the sugar, eggs and vanilla until combined.
Mix the flour, baking soda and salt, and fold them into the banana mixture just until no dry flour remains.
Pour the batter into the pan and smooth the top.
Bake for 55-65 minutes until a skewer inserted in the center comes out clean, covering the top loosely with foil if it browns too fast.
Cool in the pan for 10 minutes, then turn out onto a rack and cool completely before cutting into 8 slices.
