Ingredients

Scale

Banana Bread

  • 1 ripe banana
  • 1 egg
  • 2 tablespoons all purpose flour
  • 2 tablespoons granulated sugar
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking powder
  • Optional: crushed walnuts

Caramel Sauce

  • 1 tablespoon granulated sugar
  • 1 tablespoon water (or as much as needed to dissolve the sugar)

Instructions

  1. Mash Banana: In a small mixing bowl, mash the ripe banana thoroughly until smooth to form the base of your banana bread batter.
  2. Combine Egg: Add the egg to the mashed banana and whisk together until well combined and smooth.
  3. Add Dry Ingredients: Mix in the all-purpose flour and granulated sugar, stirring until fully incorporated into the wet ingredients.
  4. Flavor and Leaven: Pour in the vanilla extract and sprinkle the baking powder over the mixture. Stir gently to ensure even distribution.
  5. Prepare Caramel Sauce: In a microwave-safe mug, combine sugar and water. Microwave on high for approximately 2 minutes, watching carefully, until the mixture turns a deep amber caramel color. Remove the mug and swirl the caramel around the sides to coat it evenly.
  6. Microwave Banana Bread: Spoon the banana bread batter into the caramel-coated mug. Microwave on high for 1 1/2 to 2 minutes. Check doneness by inserting a toothpick or knife in the center; it should come out clean when ready.
  7. Optional Garnish: If desired, sprinkle crushed walnuts on top before serving to add crunch and texture.

Notes

  • Be attentive while microwaving the caramel sauce to avoid burning; cooking times may vary depending on microwave wattage.
  • Use a microwave-safe mug with a capacity of at least 8 ounces to prevent overflow.
  • For a richer flavor, swap out granulated sugar for brown sugar or add a pinch of cinnamon to the batter.
  • Make sure the banana is ripe for optimal sweetness and moisture.
  • This recipe is ideal as a quick dessert or snack and best enjoyed immediately for the softest texture.
