Ingredients Needed

Butter: you can use regular butter or dairy-free butter.
Chocolate: feel free to use a semisweet chocolate bar or dark chocolate! You can also use dairy-free chocolate if you’re dairy-free.
Flour: I’m using all-purpose flour, but you can swap it out for whole wheat flour if you want! Just note that the texture of the muffins will change.
Bananas: make sure the bananas you’re using are freckly with lots of brown spots! Overripe bananas not only are sweeter, but they’re easier to mash up too.

Step by Step Instructions

Chocolate Chunk Banana Muffins process in four steps

Step 1: Preheat your oven to 325°Fahrenheit and line a muffin tin with liners.

Step 2: Measure out your butter and place in a medium sized microwave-safe bowl. Heat in the microwave until melted, then whisk in the egg and vanilla extract.

Step 3: Whisk in the granulated sugar and light brown sugar.

Step 4: Mash the bananas with a fork, then mix it in with the other wet ingredients.

Step 5: Add the flour, salt, and baking soda. Whisk together, then stir in the chopped chocolate.

Step 6: Divide the muffin batter evenly between the liners, filling them so they’re almost full. Sprinkle over more chocolate on top if you want. Bake in the oven for 18-25 minutes, or until a toothpick inserted in the middle of a muffin comes out clean.

Step 7: Let them cool in the muffin pan for 5 minutes before transferring to a wire cooling rack to cool completely.

Expert Tips

I always recommend using a kitchen scale instead of measuring cups to weigh out your ingredients, especially your flour! It’s so easy to add too much flour if you use measuring cups, which is going to make your banana muffins dry and dense.
If you are using measuring cups, make sure to use the scoop and level method to weigh out the flour.
If you want to make these chocolate chunk banana muffins slightly healthier, you can use whole wheat flour. Just swap out all purpose flour for an equal amount of whole wheat flour. Just note that it will change the texture slightly!
