Ingredients

Main Ingredients

  • 3 tbsp natural peanut butter Stirred well if it is the drippy kind.
  • 1 large egg
  • 1 tbsp unsweetened cocoa powder Optional.
  • 1 to 2 tbsp zero sugar sweetener Monk fruit or erythritol blend works well.
  • 1/4 tsp baking powder
  • 1 tsp vanilla extract
  • Pinch salt Especially if your peanut butter is unsalted.
  • 1 tbsp milk of choice Optional for a softer texture.

Instructions

Preparation

  • Grab a microwave safe mug that holds at least 12 ounces to avoid overflow.
  • Add peanut butter and egg first and stir until smooth.
  • Mix in all the other ingredients.

Cooking

  • Microwave for 45 seconds.
  • Check the cake, then continue microwaving in 10 to 15 second increments until the center looks set, usually around 60 to 75 seconds total.

Notes

For serving, consider topping with sugar-free chocolate chips, Greek yogurt, or a scoop of no sugar vanilla ice cream. Adjust sweetness based on your preference, and be cautious with microwaving time to avoid rubbery texture.
