To make Cookie Monster, I used buttercream icing with blue colouring, in a piping bag with a small nozzle to get thin lines. For his eyes just a white chocolate button with some black marzipan or fondant. Don't forget you need a cookie!
For Elmo, it was pretty much the same thing except you are replacing the cookie with a single Oreo without icing. To make his nose, just use orange marzipan or fondant. I usually just have white marzipan and mix the colours myself by hand.
So that is all you need to make these cute little monsters! Oh and don't forget to make the peak of your cupcakes higher to give them more height. This also reduces the amount of icing you put on top.
Please comment! I'm getting a feeling no one is even looking at my blog LOL :)
