Position an oven rack at the top of the oven and preheat the oven to 450 degrees F.
Blend the cottage cheese until smooth.
Add the cottage cheese to a large bowl, then mix in the flour, baking powder, and salt until a dough starts to come together.
Turn the dough out on the counter, sprinkle with a little more flour, and knead into a smooth dough.
Line a large baking sheet with parchment paper. Dust your counter with flour, roll the dough into a rough square or circle, then transfer to the baking sheet.
Brush the top with olive oil. Bake for 12 minutes (no toppings).
Remove from the oven. Spread the sauce on top, making sure to leave a 1-inch border for the crust, the top with the two cheeses. Bake for 5 minutes until the cheese melts, then broil for 2-3 minutes. Cool for 2 minutes, then cut and enjoy!
