In a stand mixer, add all ingredients and mix just until combined. If you do not have a stand mixer, you can also make this using a bowl and pastry cutter or fork. I mix until the cottage cheese curds are broken down smaller than their original size, but still visible.
Scoop dough onto a clean, flour dusted, surface and divide into 4 equal sections.
Take each section of dough, and roll into a smooth, tight ball. Flatten each ball until they are a round pancake shape, approximately an inch thick. They will puff up during baking so you want to make sure you make the diameter slightly larger than needed to fit your hamburger patty on once baked.
Make an egg wash with your egg and water, and brush the top of your buns with a pastry brush. Sprinkle the top with sesame seeds, Everything bagel seasoning, or any other topping. You can also leave them plain if you prefer.
Line your air fryer with a piece of parchment.
Bake at 375℉ for 15 mintues
Allow to cool completely before splitting
