Ingredients

  • 1/3 cup creamy unsweetened natural peanut butter
  • 1 large egg
  • 1 tsp vinegar
  • 1/4 tsp baking soda
  • 1/4 tsp erythritol granular
  • 1 tbsp water

Instructions
 

  • Add all ingredients into a microwave-safe mug that can hold at least 16 oz of liquid. Mix with a mini whisk until thoroughly and evenly combined and no egg streaks remain.
  • Microwave at 800 watts for about 1 minute and 30 seconds or until bread is cooked.
  • Let bread cool slightly before removing from the mug. To remove the bread, slide a spoon to the bottom of the bread and lift the entire thing out in one piece. Use a bread knife to slice into 1/2 inch slices. Enjoy bread as is, or toast or make sandwiches with it.

Notes

  • Use a standard shaped microwave-safe mug that can hold at least 16 oz of liquid. Don't use an unusually tall and narrow mug or a short and extra-wide mug  because this can affect cooking time. My mug measured a little over 4 inches in height and is about 3 3/4 inches wide. 
  • Most newer microwave ovens in the US range between 1000 watts to 1200 watts. This bread needs to cook at a lower wattage, otherwise sections of it will overcook and become slightly hard. Make sure to adjust your cooking power level so that it cooks around 800 watts.
  • I was able to get six slices of bread measuring about 2 1/2 inches in diameter and 1/2 inch thick.
  • Do not leave out the vinegar. The vinegar is needed to activate the baking soda which allows the bread to rise. 
  • The estimated nutrition carbohydrates count excludes sugar alcohols. The net carbs excludes both fiber and sugar alcohols.
