Preheat the oven: Set the oven to 400°F and line a baking sheet with parchment paper so the flatbread releases cleanly after baking.
Blend cottage cheese and eggs: Add the cottage cheese and eggs to a blender or food processor and blend until completely smooth, about 1 minute, with no lumps remaining.
Mix in dry ingredients: Pour the blended mixture into a bowl and whisk in the flour, baking powder, salt, and garlic powder until you have a thick, smooth batter.
Spread onto the pan: Pour the batter onto the lined baking sheet and spread it into an even layer about 1/4 inch thick using a spatula.
Bake until golden: Bake for 20 to 25 minutes, until the top turns golden and the edges pull away slightly from the parchment paper.
Cool briefly: Remove the pan from the oven and let the flatbread rest for 5 minutes so it firms up enough to slice cleanly.
Slice and serve: Cut the flatbread into squares or wedges while still warm and serve plain, with toppings, or as a wrap.
Store leftovers: Transfer any extra pieces to an airtight container once fully cooled and refrigerate for up to 4 days.
