Add cottage cheese to a food processor or blender. Blend until smooth.
Add flour, baking powder and salt to a bowl. Mix together. Fold in cottage cheese. Knead with hands until everything is just combined.
Split dough into 4 even pieces. Add some flour to your hands and roll each piece of dough into ¾-inch thick ropes and join the ends to form bagels. You want to make the hole in the middle at least 1 inch big otherwise your bagel will not have a hole.
Add bagels to a sheet pan lined with parchment paper. Brush with egg (you will have a lot of egg leftover, I saved mine and scrambled it). Sprinkle over desired amount of everything bagel seasoning.
Bake bagels for 25-30 minutes and then let cool for 15 minutes before slicing. Add your favorite toppings and dig in!
