Pre-heat your oven to gas mark 6/200c.
Mash your bananas in a large bowl.
3 bananas
Add the oil and sugar, then mix really well.
6 tablespoon vegetable oil, 100 g coconut sugar
Sieve in the flour, baking powder, and then the cinnamon and mix again.
225 g plain flour, 3 teaspoon baking powder, 3 teaspoon cinnamon
Chuck in any bonus ingredients you're using, like nuts or fruit, and mix yet again.
50 g walnuts, cacao nibs, raisins
Grease a loaf tin, or line it with parchment paper, and pour your bread mix in. The consistency should be a thick batter.
If you're adding slices of banana to the top of your bread, do so now.
1 banana
Put in the oven for 40-50 minutes - the time will depend on your oven. After 20 minutes check on the loaf and cover with tin foil if the top has browned, this will stop the top from burning.
After baking for 40 minutes, check if it's done by pushing a knife or skewer into the middle of the bread and if it comes out clean, you're good to go.
