Preheat the oven to 425 F. Line a large baking sheet with parchment paper and lightly coat the parchment with a small amount of the olive oil.
Blend the cottage cheese, eggs, and remaining olive oil until completely smooth and creamy.
Stir together the oat flour, Parmesan cheese, psyllium husk, baking powder, garlic powder, and salt. Add the blended cottage cheese mixture and stir until a thick, even dough forms.
Let the dough rest for 10 minutes so the oat flour and psyllium can absorb the moisture. Spread it into a 12-inch circle about 1/4-inch thick on the prepared parchment.
Bake for 16 to 18 minutes, until the top is set and the edges are golden. Carefully turn the crust over and remove the parchment.
Bake directly on the baking sheet for another 5 to 7 minutes, until the second side is lightly browned. Cool for 3 minutes before adding pizza toppings.
