Preheat the oven to 350°F (175°C) and line a baking tray or quarter sheet pan with parchment paper.
Add the cottage cheese, eggs, oat flour, baking powder, garlic powder, Italian seasoning, salt, and black pepper to a blender or food processor.
Blend until the mixture is smooth and well combined.
Pour the batter onto the prepared baking tray and spread it into an even rectangle or oval, about ¼-inch thick.
Bake for 28-32 minutes, or until the edges are golden and the center is fully set.
Let the flatbread cool for 5-10 minutes before carefully removing it from the parchment paper.
Slice and enjoy as a wrap, sandwich, pizza base, or with your favorite dips.
