Ingredients
  

Air Fryer Banana Chocolate Mug Cake

  • 1 ripe banana mashed well
  • 3 tablespoons oat flour
  • 1 tablespoons unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • 1 piece dark chocolate 70%, for the top (optional)

Air Fryer Peanut Butter Mug Cake

  • 4 tablespoons All-purpose flour
  • ¼ teaspoon baking powder
  • 2 tablespoons smooth natural peanut butter (no sugar added)
  • 4 tablespoons oat milk
  • extra smooth natural peanut butter for topping

Instructions
 

Air Fryer Banana Chocolate Mug Cake

  • Mash the ripe banana until smooth.
  • In a bowl, mix the oat flour, cocoa powder and baking powder.
  • Add the mashed banana and mix until you get a thick batter.
  • Spoon the batter into a small oven-safe ramekin or mug.
  • Place the piece of dark chocolate on top.
  • Air fry at 325°F (160°C) for 11-13 minutes, or until the top looks set.
  • Let it cool for 2-3 minutes before eating, because the inside will be very hot and the texture firms up slightly as it sits.

Air Fryer Peanut Butter Mug Cake

  • In a small bowl, mix the flour and baking powder.
  • Add the peanut butter and oat milk.
  • Mix until you get a thick, smooth batter. It should be like a soft cake batter, not dry dough. If the peanut butter is very thick, add 1 extra tsp oat milk.
  • Spoon the batter into a small oven-safe ramekin or mug.
  • Air fry at 325°F (160°C) for 10-12 minutes, or until the top is set and the cake has risen.
  • Let it cool for 2-3 minutes.
  • Top with smooth natural peanut butter before serving.

Notes

For a sweeter version, you can replace the peanut butter inside the batter with sweetened peanut butter or Biscoff spread
