Banana Oat Yogurt Muffins

Had some very black bananas that were ripening the tomatoes in the airing cupboard so made the Banana Bread and tried these muffins. They didn't turn out very banana tasting so would use 2 bananas next time. I made 6 with walnuts and 6 with chocolate chips.

100g soft butter
160g dark brown sugar
1 egg
1 ripe banana
2 tbsp fat free yogurt
1 tsp vanilla extract
1 tsp cinnamon
1/2 tsp ground cloves
1 cup plain flour
1 cup porridge oats
1 tsp baking powder
Chopped Walnuts or chocolate chips

Beat butter and sugar till creamy
Add egg, vanilla, cinnamon and cloves to butter and mix well
Mash banana with yogurt and stir into mix
Stir in flour, oats and baking powder
Add walnuts or chocolate chips
Spoon mixture into muffin cases and bake Gas 5 Electric Fan 160 for 20 minutes or until done
Cool on a wire rack
