Chocolate spiderweb cupcakes

Method

1. Heat the oven to 180°C/160°C fan /gas 4. Put all the cake ingredients into a large mixing bowl and beat with an electric hand whisk until combined and smooth.
2. Divide the cake mix between a 12-hole muffin tin lined with paper cases. Bake for 15-18 minutes, until well risen and springy to the touch.  Leave to cool on a wire rack.
3. To decorate cover half the cakes with melted milk chocolate and half with melted white chocolate. Pipe 3 concentric circles on top of each one using the writing icing tubes (use dark on white and vice versa), then use a cocktail stick pull from the middle to the edge all the way round to create a web effect.
