Place all of the ingredients, except for the parsley, into a bowl and whisk everything together.
Pour this mixture about half way up 4-5 microwave-safe mugs, and then microwave them individually for 1 minute and 30 seconds, or until the cake has risen and is fluffy and airy.
Make a hole in the top of each cake with a bamboo skewer, and insert a few stems of fresh parsley to look like a carrot.
