Preheat the oven to 400°F and line a large rimmed baking sheet with parchment paper.
Add the cottage cheese, eggs, and italian seasoning to a blender and blend until smooth. Transfer the cottage cheese mixture to a bowl and stir in the flour until combined.
Pour the pizza dough onto the prepared baking sheet and spread into a 10-inch circle. Bake in the preheated oven for 13-15 minutes, until golden brown. The crust will bubble and settle as it cools.
When the crust is done, spread the pizza sauce on top, then arrange the mozzarella, pepperoni, and shredded cheese. Bake again for another 12-15 minutes, until the cheese is melted, bubbling, and golden brown. Allow to cool for 5-10 minutes before slicing.
