Chocolate banana muffins

These made the kitchen smell utterly heavenly and they tasted great too...

1/2 cup or 100g all purpose flour or self raising flour if you're a Brit
1 teaspoon baking powder
1/2 cup or 100g caster / superfine sugar
1 stick or 100g butter
2 eggs
1 ripe banana
1/3 cup or 2 ounces cocoa powder - NOT HOT CHOCOLATE!!!

1: Light the oven to 190 degrees C, 375 degrees F, Gas mark 5
2: Sieve the flour, baking powder and cocoa together
3: Mash the banana until nice and runny
4: Cream the butter and sugar together until light and fluffy - I cheated and used the KitchenAid
5: Add the eggs, one at a time, with a tablespoon of flour cocoa mix
6: Add the rest of the flour mix and mix until a smooth, creamy, thick batter
7: Spoon the mixture into 10 baking cases
8: Cook for around 15 minutes until risen and springy

When cold, I spread the tops with Nutella or your preferred chocolate frosting.

Enjoy!
