An easy banana fairy cake with the addition of chopped nuts and chocolate frosting. Perfect for making with kids or packing in lunchboxes - and a great way to use up leftover bananas and cut down on food waste! Makes 12 fairy cakes.
Preheat the oven to 180'C / Fan 160'C / Gas Mark 4. Place 12 cupcakes cases in a 12-hole muffin tin and set to one side.
Add the sugar, butter, mashed banana, self-raising gluten free flour, xanthan gum, eggs and vanilla extract to a large mixing bowl. Beat with an electric mixer until it forms a thick batter.
Add the mixed nuts and fold in to mix. Spoon the batter evenly between the 12 cupcake cases and bake in the oven for 20-22 minutes until they are well risen and golden on top. They should spring back when lightly touched. Remove from the oven and cool completely on a wire rack.
To make the frosting, beat the icing sugar, cocoa powder, milk and vanilla extract together until they form a thick paste. Use a small palette knife or spoon to smooth the frosting on the top of the cakes, then sprinkle with extra chopped nuts if using.

Notes
These banana fairy cakes will store in an airtight container for 3-5 days. You can also freeze them - works better without the frosting.
If you don't have self-raising flour use plain gluten free flour and add 1 tsp of baking powder to the mixture as well.
