Preheat oven to 350F and line muffin tin with muffin liners. I also spray muffin liners with nonstick spray.
In a small bowl, combine oat flour, baking powder, baking soda, salt, and cinnamon.
In a large bowl, whisk together eggs, applesauce, and oil. Add in maple syrup and vanilla. Whisk till well combined.
Add dry ingredients to wet and stir until combined, not overmixing.
Gently fold in in zucchini and chocolate chips.
Scoop into muffin liners and bake 20-22 minutes.
Let cool at least 15 minutes before eating. Store on counter.
