Preheat oven to 350 degrees Fahrenheit. Line a muffin tray with muffin liners.

In a blender, process bananas with water until completely smooth.

In a large bowl, combine blended bananas with maple syrup, sugar, and vanilla.

In a second bowl, combine flour, salt, baking powder, and baking soda, whisking until free of lumps.

Gently fold wet ingredients into the flour mixture until a smooth batter forms. Stir in chocolate chips until just incorporated.

Fill muffin liners three-fourths of the way and bake 30–40 minutes, or until a toothpick inserted in the center comes out clean.
