Warm Banana Cupcakes with Custard

Ingredients (serves 4)
1 1/4 cups self-raising flour, sifted
1/2 cup brown sugar
1.5 oz butter, melted and cooled
1 egg
1/3 cup milk
2 ripe bananas, mashed
1 1/2 cups prepared custard

Directions:
Preheat oven to 400 F. Grease 4 large muffin pans. Combine flour and sugar in a mixing bowl. Make a well in the centre.
Using a fork, whisk butter, egg, milk, and bananas together in a jug. Add to flour mixture and fold together until just combined.
Spoon into prepared pans and bake for 25 minutes or until a skewer inserted into the middle of a muffin comes out clean. Cool in the pans for 5 minutes, then transfer to serving plates.
Meanwhile, place custard into a saucepan and warm over medium-low heat. Serve with banana muffins.
