Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

Blend cottage cheese in a blender or food processor for about 45 seconds until completely smooth with no lumps.

In a bowl, whisk together the blended cottage cheese, eggs, Greek yogurt, peanut butter, honey, and vanilla extract until smooth and combined.

In a separate bowl, whisk oat flour, baking powder, cinnamon, and salt.

Fold the dry ingredients into the wet ingredients with a spatula until no flour streaks remain. Do not overmix.

Use a tablespoon or cookie scoop to drop dough onto the baking sheet, spacing about 2 inches apart.

Bake for 15-18 minutes until edges are lightly golden but centers remain soft.

Cool on baking sheet for 5 minutes, then transfer to a cooling rack to finish cooling.
