Preheat oven to 350 degrees Fahrenheit (175 degrees Celsius) and line a large baking sheet with parchment paper.

In a large mixing bowl, whisk together the cottage cheese, maple syrup, vanilla extract, and egg until the mixture is homogeneous.

In a separate bowl, combine the rolled oats, oat flour, baking powder, cinnamon, and salt.

Fold the dry ingredients into the wet mixture until a thick, cohesive dough forms.

Use a cookie scoop to portion 12 equal mounds onto the prepared baking sheet, flattening each slightly with the back of a spoon.

Bake for 15 to 18 minutes or until the cookies are firm and the edges are lightly golden brown.

Allow the cookies to cool on the baking sheet for at least 5 minutes before transferring to a wire cooling rack.
