1cupchocolate chunkssemi-sweet
Instructions
Start by lining a muffin pan with muffin liners (or grease each cup if you’re skipping liners). Set the pan aside and preheat your oven to 400°F. This high temperature helps create tall, fluffy muffins.
In a large mixing bowl, stir together the all-purpose flour, granulated sugar, baking soda, baking powder, and salt. Mix thoroughly so your dry ingredients are evenly distributed.
2 cups all-purpose flour, 3/4 cup granulated sugar, 1/4 tsp baking soda, 2 tsp baking powder, 1/2 tsp 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 and smooth—room temperature ingredients blend much more easily.
1.5 cups bananas, 1/4 cup sour cream, 1/2 cup whole milk, 1/2 cup vegetable oil, 2 large eggs, 1 teaspoon pure vanilla extract
Make a well in the center of the dry ingredients, then pour in the wet mixture. Gently fold everything together by hand until no large streaks of flour remain. Be careful not to overmix, or you’ll end up with rubbery muffins. The muffin batter should be thick and slightly lumpy.
Fold in the chocolate chunks, distributing them evenly throughout the batter.
1 cup chocolate chunks
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.
Notes
Add-ons & Substitutions
Want to make these muffins your own? Here are some easy swaps and extras:
Swap the semi-sweet chocolate chunks for milk chocolate, bittersweet chocolate, or even white chocolate for a twist.
Use Greek yogurt instead of sour cream if that’s what you have on hand.
Mix in chopped nuts, like walnuts or pecans, for added crunch and a nutty flavor.
Make mini muffins by using a mini muffin pan—just reduce the bake time.
Top with turbinado sugar for an extra crunchy muffin top.
Expert Tips
Let your bananas get nice and overripe—look for lots of brown spots. The darker they are, the better the banana flavor.
Make sure all your wet ingredients (especially sour cream, milk, and eggs) are at room temperature. This helps them blend smoothly and gives the muffins a better rise.
Use an ice cream scoop for even-sized muffins. That way, they bake consistently and look great.
Don’t overmix the batter. Stir until everything is just combined. Overmixing develops too much gluten and leads to tough, dense muffins.
Use muffin liners if you’re planning to freeze or store them for a few days. It keeps them from sticking and makes cleanup easier.
For bakery-style muffin tops, bake at a high temperature for the first few minutes. This activates the leavening agents and gives you those tall, fluffy domes.
