Ingredients

  • 1 tablespoon unsalted butter
  • 3 tablespoon ripe banana mashed
  • 2 tablespoons milk or milk alternative
  • ½ teaspoon vanilla extract
  • ¼ cup all-purpose flour
  • 1 tablespoon brown sugar packed
  • 1 teaspoon baking powder
  • ¼ teaspoon ground cinnamon
  • 1 pinch salt

Instructions

  • Add the butter to the mug and microwave for about 20 to 30 seconds or until melted.
  • Add the mashed banana, milk, and vanilla extract, mixing thoroughly with a fork to combine.
  • Stir in the flour a little bit at a time, then mix in the remaining dry ingredients: sugar, baking powder, cinnamon, and salt.
  • Microwave for about 90 seconds.* This will take more or less time depending on your microwave's wattage. It is normal for the cake to rise above the rim of the mug as it cooks and sink as it cools. If the cake is still uncooked, microwave in 10-second increments.
