Bolu-mamar (banana cake)

Instructions

1. Preheat the oven to 175 °C and butter or line a loaf tin.
2. Mash the bananas with a fork until you have a fairly smooth purée.
3. In a bowl, whisk the eggs with the sugar until the mixture lightens slightly.
4. Add the banana purée, oil and vanilla, then mix well.
5. Fold in the flour, baking powder, cinnamon and salt, mixing just until no lumps remain.
6. Add the chopped nuts if using, then pour the batter into the tin.
7. Bake for 40 to 45 minutes. Check with a knife tip, which should come out dry.
8. Leave to cool for 10 minutes before turning out onto a rack.
