Warm and cosy molten-centred chocolate cupcakes

1. Preheat the oven to 190C/375F/Gas Mark 5. Put 8 paper baking cases in a bun tray, or put 8 double layer paper cases on a baking tray.

2. Put the margarine, sugar, egg, flour and cocoa powderin a large bowl and, using an electric hand whisk, beat together until just smooth.

3. Spoon half the mixture into the paper cases. Using a teaspoon, make an indentation in the centre of each cake. Break the chocolate evenly into 8 squares and place a piecein each indentation, then spoon the remaining cake mixture on top.

4. Bake the cupcakes in the oven for 20 mins, or until well risen and springy when you touch it. Leave the cupcakes for 2-3 minutes before serving warm, dusted with sifted icing sugar.

5. Keep stored in an air tight container and before serving, heat in microwave for 30 secs.
