The cutest little fluffy and soft blueberry muffins inspired by Little Bites.
Preheat oven to 350°F. Line a mini muffin tin with mini muffin liners.
In a large mixing bowl, whisk together mashed banana, greek yogurt, maple syrup, butter, milk, sugar, egg, vinegar, and vanilla until combined. Add flours, cornstarch, baking powder and soda, and salt. Use a rubber spatula or wooden spoon to fold dry ingredients into wet until a smooth batter forms. Fold in blueberries.
Fill each muffin liner mostly full with batter. Bake for 12-13 minutes until toothpick inserted comes out mostly clean (a few moist crumbs is ok).
Allow muffins to cool in the tin for 5 minutes before carefully transferring to a wire cooling rack.
