Preheat your oven to 450°F and line a baking sheet with parchment paper, lightly greasing the parchment. While the oven heats, add the cottage cheese to a blender or food processor and blend until completely smooth with no visible curds—this step is crucial because it creates a uniform dough texture and helps the crust bind together properly.
In a medium bowl, whisk together the flour, baking powder, and salt. Add the blended cottage cheese from Step 1 and stir until a shaggy dough forms—don't overmix, just combine until everything comes together. The dough will be slightly sticky and wetter than traditional pizza dough, which is exactly what you want.
Transfer the dough to your prepared parchment-lined baking sheet. Using your hands or a spatula, gently press and flatten the dough into a 12-inch circle, creating an even thickness throughout—I find it helps to lightly oil your hands first so the dough doesn't stick as much. Bake for 10-12 minutes until the crust is set and lightly golden around the edges. This pre-baking step ensures the crust is fully cooked and won't be soggy when you add toppings.
Remove the pre-baked crust from the oven and spread the pizza sauce evenly over the surface, leaving a small border around the edges. Sprinkle the cheese and your desired assorted toppings over the sauce. Return the pizza to the oven and broil for 1-2 minutes, watching carefully to prevent burning, until the cheese melts and the toppings are heated through.
