Set the oven to 350°F (180°C). Either grease a 20 cm (7.9-inch) loaf pan lightly or line it with parchment paper.

Mash the bananas in a big bowl. Add the Greek yogurt, egg, maple syrup, cinnamon, vanilla, and salt, then stir everything until it's smooth.

Pour the oat flour, almond flour (or extra oat flour), and baking powder into the banana mixture. Mix it all together gently. If you're using chocolate chips, toss them in. If the batter's too thick, thin it with a dash of milk. If it's too thin, add a bit more flour – the banana size can affect this.

Spoon the batter into the prepared loaf pan and pop it in the oven to bake for 30-35 minutes. It's done when a toothpick comes out clean after poking the center.

Let the loaf sit in the pan for around 10 minutes, then remove it and place it on a wire rack to cool completely before cutting it.
