Start your day with these fluffy banana blueberry oat muffins! Bursting with fresh berries and hearty oats, they're a perfect grab-and-go breakfast for the whole family.
Preheat the oven to 350°F. Line a muffin pan with paper liners.
In a large bowl, mash the bananas. Whisk in the eggs, buttermilk, and vanilla extract until combined.
In a separate bowl, combine the whole wheat flour, all-purpose flour, rolled oats, sugar, baking powder, and baking soda.
Gradually fold the dry ingredients into the wet ingredients until just combined. Do not overmix.
Gently fold in the blueberries. Fill each muffin cup about ¾ full. Sprinkle the tops with coarse sugar if desired.
Bake the muffins for 20–30 minutes, or until a toothpick inserted into the center comes out clean. Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely. Enjoy!
