Preheat the oven: Heat the oven to 350°F and line a baking sheet with parchment paper. Lightly spray or brush the parchment with olive oil so the baked flatbread releases cleanly.
Add cottage cheese and eggs: Add the cottage cheese and eggs to a blender. There's no need to drain the cottage cheese first.
Blend until smooth: Run the blender for about 1 minute, scraping down the sides once, until the batter is completely smooth with no visible curds.
Season the batter: Pour the batter into a bowl and stir in the salt, garlic powder, and black pepper until evenly combined.
Pour onto the pan: Pour the batter onto the prepared parchment paper in the center of the baking sheet.
Spread into an oval: Use an offset spatula or the back of a spoon to spread the batter into an even oval about 1/4 inch thick, keeping the edges roughly the same thickness as the center.
Bake until golden: Bake for 25 minutes, until the edges turn golden and pull away slightly from the parchment and the center feels set when pressed lightly.
Cool on the pan: Remove the baking sheet from the oven and let the flatbread rest for 5 minutes. This short cooling period firms the structure so it won't tear when lifted.
Peel and serve: Gently peel the parchment paper away from the flatbread. Slice into wedges or keep whole to use as a wrap.
