Enjoy these Banana Chocolate Chip Muffins for breakfast or dessert. Instructions for small batch or mini muffins, making them healthy, gluten-free, vegan, etc. provided. They are easy to make and call for 11 ingredients and 15 minutes of hands-on preparation time. They are super soft and moist and come with a crunchy streusel topping.
Preheat oven to 425°F (220°C). Line two 12 muffin pans with about 19-20 muffin liners. Set aside.
Make the muffins: Combine flour, baking powder, and salt in a medium bowl. Set aside.
In a large mixing bowl, using a whisk, stir mashed bananas and sugar just until combined. Slowly mix in vegetable oil just until combined. Add eggs and vanilla* and stir just until incorporated. Add dry ingredients and stir to combine. Don't overmix at any step. Fold in chocolate chips and banana chunks just until combined. Set aside.
Make the streusel: In a medium bowl combine flour, sugar, and butter and mix with your fingers until you have a crumbly mixture.
Assemble: Divide batter into muffin liners and sprinkle with streusel (and a few additional chocolate chips on top if desired). Fill liners between 3/4 and almost full. Look at the step-by-step photos above. You will get about 20 muffins.
Bake at 425°F (220°C) for 5 minutes then lower the temperature to 350°F (175°C) and bake additional 11-13 minutes or until a toothpick in the center comes out clean. Don't overbake or your muffins will end up dry. Let cool for about 10 minutes then transfer to a wire rack to cool completely.
Store leftovers in an airtight container at room temperature up to 3 days.
*First, cut off the straight end of the vanilla bean. Then place the tip of your sharp knife below the curled end and cut the vanilla bean through the middle of the bean lengthwise. Although you don't need to cut it all the way through, it's ok when you do so. Then open the vanilla bean and scrape out the flavorful seeds with the back of your knife. Just use the seeds.

When you want to make mini muffins, line three 24 mini muffin pans with about 55 mini muffin liners. Bake mini muffins for about 6-8 minutes or until a toothpick comes out clean. Be careful, they overbake very quickly because of their small size.
