Preparation Steps

• Preheat the oven to 350°F (175°C). Line a muffin tin with cupcake liners.
• In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
• In a large bowl, whisk the egg and sugar together until well combined, then add the melted butter.
• Add the mashed bananas and vanilla extract to the egg mixture and combine thoroughly.
• Add the dry ingredients to the wet ingredients and mix until just combined, then fold in the chocolate chips.
• Spoon the batter into the prepared muffin tin, filling each cup about 3/4 full.
• Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
• Allow the cupcakes to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
