There is nothing like a homemade mug cake for dessert. Today, I made a simple Air Fryer Peanut Butter Mug Cake, and it was awesome. Done in less than 10 minutes from start to finish, it is the perfect air fryer dessert.


  • 3 tablespoons all-purpose flour
  • 2 tablespoons sugar
  • 1 teaspoon baking powder
  • 3 tablespoon milk
  • 2 tablespoons creamy peanut butter


  1. In a small bowl, mix the flour, sugar, baking powder, and milk.
  2. Fold in the peanut butter, mix until smooth.
  3. Spoon into an oven-safe mug.
  4. Set the mug into the air fryer for 5-6 minutes at 330 degrees F, air fryer setting.
  5. Garnish with whipped cream or frosting, and sprinkle some peanut butter chips on top.
  6. Plate, serve, and enjoy!
