1Preheat oven to 400°F (205°C). In a small bowl, stir together the melted butter and garlic. Add 1 tablespoon of the garlic butter to a blender pitcher. Use the remaining to thoroughly grease the inside of each well in a mini or regular size muffin tin.
2Add cottage cheese, eggs, 4 oz (about 1 cup, grated) mozzarella, salt, and tapioca flour to the garlic butter in the blender. Purée on very high until super smooth - about one minute.
3Pour batter into each muffin well, filling up each well about halfway. Place a teaspoon of pizza sauce in the center of each well, top with pepperoni and a sprinkle of cheese.
4Bake for 20-30 minutes until the pizza bites have puffed and turned deep golden brown. Serve with remaining pizza sauce.
