Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
Add the cottage cheese and eggs to a bowl and blend until smooth using an immersion blender, or transfer to a blender.
Stir in the flour, baking powder, and salt until fully combined. The mixture should be thick but scoopable. Add a little more flour if it feels too loose.
Spoon the batter into 6 rounds on the prepared baking sheet. Use the back of a spoon to gently flatten and shape into mini pizza bases.
Spread a small amount of pizza sauce over each base, then top with mozzarella, cheddar, tomatoes, red onion, hot peppers, olives, feta, and oregano.
Bake for 15 to 20 minutes, until the crusts are set and lightly golden.
Let cool for a few minutes before serving to allow them to firm up.
Notes
These store well in the fridge or freezer and reheat beautifully.
If the batter spreads too much, add an extra tablespoon or two of flour to thicken it.
Swap toppings based on what you have. Pepperoni, roasted vegetables, or hot honey and ricotta all work great.
