Flourless Microwave Peanut Butter Cake

  • Total Time: 3 minutes
  • Yield: 2 cakes 1x


  • ¼ cup granulated sugar
  • ½ teaspoon baking powder
  • 2 large eggs
  • ¼ cup creamy peanut butter
  • 1 teaspoon pure vanilla extract


  1. Lightly oil two large coffee mugs.
  2. In a medium bowl, stir together sugar, baking powder, eggs, peanut butter, and vanilla until well combined. Divide equally among the mugs.
