In a large, microwave-safe mug, add all ingredients. Whisk until smooth.
Cook in microwave at full power for about 2 minutes 20 seconds. Allow the bread to cool about 1 minute before removing from mug and slicing. I sliced mine into ½ inch thick discs.
The breads can be used as is for sandwiches or can be toasted. I prefer the texture when the bread is toasted.
Notes
You can use canola oil, vegetable oil, olive oil. If you are trying to make it paleo, keto, or have other dietary restrictions, please use an oil that is permitted in the diet you are following.
You can add a pinch of salt to the batter. You can also add dried herbs for more flavor.
Any leftover bread should be stored in the fridge in an airtight container. It can keep for about 3 days. It will need to be reheated before consuming.
You should use a wide mug because if your mug is too narrow, it will be difficult to cook the bread all the way through and your bread slices will be very small. Your mug should hold at least 16 oz of liquid. The mug I used is 4 inches tall and 3 ¼ inches wide.
