Done with a butter cream icing, the spider-web technique is one of the many simple cupcake decorations that can be done. To make your butter-cream icing you will need 100gms of unsalted butter and a 200gms of icing sugar. Mix them well to get a toothpaste like consistency. Mix a fair amount of the icing along with food colouring of your choice. Once done you can take a piping bag and fill your icing. Follow the rest of the instructions and you have your spiderweb designed cupcake.
