Step 1

Heat the oven to 170C (150C fan)/335F/gas 3½, and line a six-hole muffin tray with paper liners.

Step 2

Put the bananas and buttermilk in a bowl, mix to combine, then stir in the beaten egg and oil.

Step 3

In a separate bowl, mix the flour, sugars, spices, baking powder and bicarb. Make a well in the centre and pour in the banana mixture, followed by the melted butter.

Step 4

Stir briefly to combine, being careful not to overmix. The batter will be quite thick.

Step 5

Divide the batter evenly between the muffin holes and bake for 23-26 minutes, until the muffins are well risen and golden. Leave to cool completely before serving.
