Banana And Nutella Muffins

Preheat the oven to gas mark 5 / 190C / 375F. Add the egg to the mashed bananas in a large bowl and beat with a fork until incorporated.

Add the sugars and the melted butter and beat again until combined.

Stir together dry ingredients and sift into wet. Tip in the bran left in the sieve. Fold the dry ingredients gently into the wet in figure-of-eight movements with a metal spoon.

Spoon mixture into muffin cases. If nutella is not soft, gently warm in microwave. Add 1/2 tsp to each case and swirl with a cocktail stick.

Bake for 20 minutes, then insert a knife. If blade comes out clean, they are done. If not, return to oven and keep checking.
