There’s nothing like the smell of Simple bakery-style banana chocolate chunk muffins wafting through your kitchen. This recipe gives you moist banana muffins with gooey chocolate chunks and a fluffy texture—no fancy tools or steps needed. Whether you’re baking for the first time or just need an easy go-to, this one is sure to win you over.

In a large mixing bowl, stir together the all-purpose flour, granulated sugar, baking soda, baking powder, and salt. In a separate bowl, whisk together the mashed bananas, sour cream, milk, vegetable oil, eggs, and vanilla extract. Make sure everything is well combined

Make a well in the center of the dry ingredients, then pour in the wet mixture. Gently fold everything together by hand. Fold in the chocolate chunks, distributing them evenly throughout the batter.

Using a large ice cream scoop or measuring cup, fill each muffin cup about ¾ full. If you like, sprinkle a few extra chocolate chunks and a pinch of sugar on top for a crisp finish. Bake for 5 minutes at 400°F. Then, without opening the oven, reduce the temperature to 350°F and continue baking for 20–25 minutes.

The muffin tops should be golden brown, and a toothpick inserted in the center should come out clean. Cool the muffins in the pan for 5 minutes, then transfer to a wire rack to cool completely before storing.
