Preheat the oven to 350 degrees.
Whisk together the salt, baking soda, flour, and cinnamon in a mixing bowl.
In a separate bowl, whisk together the wet ingredients: mashed bananas, yogurt, eggs, vanilla extract, and maple syrup.
Add the dry ingredients to the wet and mix until just combined using a rubber spatula.
Grease a mini muffin tin with cooking spray.
Use a mini cookie scoop to distribute the batter evenly into the mini muffin tin. The tins should be filled up to the top of all 24 mini muffin spots.
Bake the muffins at 350 degrees for 13-16 minutes, or until a toothpick inserted comes out clean.
Allow the muffins to cool several minutes in the muffin pan, then transfer them to a wire cooling rack to cool completely. Store leftovers in an airtight container in the refrigerator.
