Ingredients

Scale

Main Ingredients

  • 2 tablespoons mashed ripe banana
  • 1 tablespoon creamy peanut butter (plus more for topping)
  • 1 tablespoon maple syrup or honey
  • 3 tablespoons all-purpose flour
  • ½ teaspoon baking powder
  • Pinch of salt
  • 1 tablespoon milk (any kind)
  • Optional: 1 tablespoon peanut butter chips or chocolate chips

Instructions

  1. Prepare the Mug: In a microwave-safe mug, mash the ripe banana thoroughly to create a smooth base.
  2. Mix Wet Ingredients: Stir in the creamy peanut butter, maple syrup (or honey), and milk until the mixture is smooth and well combined.
  3. Add Dry Ingredients: Add the all-purpose flour, baking powder, and a pinch of salt to the wet mixture. Gently mix until just combined, avoiding over-mixing to keep the cake tender.
  4. Fold in Chips: If using, fold in peanut butter chips or chocolate chips evenly into the batter.
  5. Cook the Mug Cake: Microwave the mug on high power for 60 to 75 seconds. The cake should be set on the edges but slightly soft and gooey in the center for a moist texture.
  6. Garnish and Serve: Top the warm mug cake with a swirl of extra peanut butter and a slice of banana for added flavor and presentation. Serve immediately.

Notes

  • You can substitute maple syrup with honey or any liquid sweetener of your choice.
  • The mug cake is best enjoyed fresh out of the microwave when still warm and gooey.
  • For a dairy-free version, use any plant-based milk.
  • Adjust microwave power and time as needed depending on your microwave wattage.
  • Optional chips add extra texture and flavor but can be omitted.
