In a mixing bowl, blend the cottage cheese until smooth, then add in the oat flour, egg, salt, and baking powder, stirring until a cohesive dough forms. Let the dough rest for 5–10 minutes.

Roll the rested dough out on a floured surface to about ¼ inch thick. Aim for a smooth and uniform shape.

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and place the rolled dough on it. Bake for 15 minutes until golden edges and a set surface.

For an extra crispy finish, heat a skillet over medium-high heat and toast each side of the baked flatbread for about 30 seconds.
