Step 1

Preheat the oven to 450 F/230 C/210 fan/gas mark Lightly grease a 12-hole muffin pan or line with paper cases. Set aside.

Step 2

Prepare dry ingredients: Combine the flours, baking powder, bicarbonate of soda and cinnamon. Stir thoroughly using a whisk.

Step 3

Mash bananas: In a wide shallow bowl mash the bananas. TIP: To speed things up (this recipe contains quite a lot of bananas) you can use a potato masher to start with and finish off with a fork.

Step 4

Prepare wet mixture: Whisk together the mashed bananas, egg, oil, buttermilk and sugar until thoroughly combined.

Step 5

Assemble batter: Combine both mixtures and stir together using a whisk. Stir only until the dry ingredients are no longer visible.

Step 6

Bake: Spoon the batter into the muffin cases and bake in the centre of the oven for 8 minutes. Without opening the oven door turn the temperature down to 350 F/180 C/160 fan/gas mark 4 and continue baking for 15-17 minutes until a skewer inserted into the middle of a muffin comes out clean.

Step 7

Cool: Remove from the oven and set aside to cool.
