Banana Muffin

Preheat the oven to 160 °C (fan) and line a muffin tin with paper cases.

Peel the banana and mash it finely with a fork.

In a bowl, mix the flour, baking powder, baking soda, cinnamon and cocoa powder well.

In a second bowl, whisk the egg, mashed banana, sugar, oil and buttermilk until frothy.

Briefly fold the flour mixture into the wet ingredients, only until no dry flour is visible.

Fill the batter into the cases and bake for 20–25 minutes. Let rest for 5 minutes, then remove from the tin and cool completely on a wire rack.
