Preheat the oven to 350°F and line a baking sheet with parchment paper.
Blend the cottage cheese, egg, sugar, melted coconut oil, lime juice, and lime zest until smooth.
Whisk the vanilla protein powder, oat flour, coconut flour, shredded coconut, baking powder, and salt in a bowl.
Stir the blended cottage cheese mixture into the dry ingredients until a thick dough forms.
Rest the dough for 15 minutes so the coconut flour can absorb the moisture.
Scoop 12 portions onto the baking sheet and flatten each cookie to about 1/2 inch thick.
Bake for 12 to 14 minutes, until the edges are lightly golden. Cool completely before serving for the best chewy texture.
