2/3cupmilk

2teaspoonsvanilla extract

1/2cupflour
1/2cuprolled oats
1/4cupbrown sugar
1/2teaspooncinnamon
4tablespoonsunsalted buttermelted
Instructions
Preheat oven to 375 degrees F. Line a 12-cup muffin pan with paper liners or spray generously with nonstick cooking spray.
In a medium bowl, stir together the flour, rolled oats, sugars, baking powder, baking soda, cinnamon, and salt.
In a large bowl, combine the mashed banana, oil, milk, egg, and vanilla extract. Now add the dry mixture to the wet mixture and stir just until combined.
Fill the muffin cavities just shy of the top with the batter.
In a medium bowl, make the topping. Stir together the flour, rolled oats, brown sugar, and cinnamon. Pour in the butter and stir with a fork until the mixture forms crumbs.
Sprinkle the crumb mixture evenly over the top of the muffin batter and gently press down, so it sticks. Bake for 18-20 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
Let the muffins cool in the pan for 5-10 minutes before transferring them to a wire rack to cool.
Notes
Use very ripe bananas for these. They are much easier to mash, have more flavor, and moisten baked goods.
For accurate measuring, use a food scale or scoop the flour into the measuring cup with a spoon. Then, level it off with a table knife, pushing the excess back into the flour canister.
Store the muffins in an airtight container on the counter for up to 4 days or freeze them for up to 3 months.
