Preheat your oven to 375°F (190°C) to ensure even baking.
In a mixing bowl, whisk together the flour, baking powder, and kosher salt until well combined.
Add the cottage cheese and egg white (or whole egg) to the dry ingredients. Mix well until a dough forms.
Dust your hands with flour, divide the dough into four equal portions, roll into balls, and poke a hole in the center to form bagels.
If using toppings, sprinkle them over the bagels before placing them on the baking sheet.
Place the bagels on a baking sheet and bake for about 20-25 minutes until golden brown and firm to the touch.
Transfer the bagels to a cooling rack and let them cool for a few minutes before slicing and enjoying.
