Preheat the oven to 450 degrees.
Blend the cottage cheese in a food processor or blender until smooth and creamy.
In a mixing bowl, combine the cottage cheese mixture with the flour and baking powder. Mix until the dough starts to form. If it feels too sticky, add a little more flour until it’s easier to handle.
Lay a sheet of parchment paper on a pizza pan or baking sheet. Place the dough on the parchment and gently press it into two circles, about 12 inches in diameter.
Pop the crust into the oven (without any toppings) and bake for 8-10 minutes. The edges should start to turn golden.
Remove the crust from the oven and spread the pizza sauce over the top. Sprinkle the shredded mozzarella cheese, add the pepperoni slices, and sprinkle with Italian seasoning.
Return the pizza to the oven and bake for another 5 minutes until the cheese is melted and bubbly.
Finally, broil for 2-3 minutes to give the cheese and crust edges a golden-brown finish.
