Ingredients

• 1 medium ripe banana
• 4 tbsp all-purpose flour
• 2 tbsp brown sugar
• 1/4 tsp baking powder
• 2 tbsp milk
• 1 tbsp vegetable oil
• 1/4 tsp vanilla extract

Instructions

1. Step 1: In a large microwave-safe mug, mash 1 medium ripe banana with a fork until mostly smooth.
2. Step 2: Add 4 tablespoons all-purpose flour, 2 tablespoons brown sugar, and 1/4 teaspoon baking powder to the mug. Stir to combine evenly.
3. Step 3: Pour in 2 tablespoons milk, 1 tablespoon vegetable oil, and 1/4 teaspoon vanilla extract. Mix thoroughly to form a smooth batter.
4. Step 4: Microwave on high power for 90 seconds, then check the doneness by inserting a toothpick; if wet batter remains, microwave in additional 15-second increments until cooked through.
