Combine all ingredients in an oversized coffee mug. Whisk well with a small whisk until smooth.
Microwave on high for 1 1/2 minutes and then take it out to check to see if it is done. If not, continue to microwave in thirty second intervals. Mine was done at 2 minutes. You don’t want to overcook it or it will become rubbery.
You can also make this into two smaller-sized mugs. You can mix the batter all in one mug and then pour half into another mug. Make sure you cook each one individually.
