Stir ingredients together in a mug and microwave for 1 1/2 minutes, or until there is no liquid batter remaining on the top!
Cook time may vary per microwave since every microwave is a little different. 1 1/2 minutes was perfect for me, but if yours isn’t done, throw it in for extra fifteen second intervals until the batter on the top is all “baked” and set – no longer liquidy!
