In a medium bowl, whisk together the flour and baking powder. Add a pinch of salt if using.

Make a well in the center and add the cottage cheese. Mix using a fork or spatula until a chunky dough begins to form.

Transfer the dough to a floured surface and knead for 1–2 minutes until a soft, cohesive dough ball forms. Add more flour as needed if the dough is sticky.

Divide dough into 4 equal pieces. Roll each piece into a log about 6–7 inches long and ¾ inch thick. Shape each log into a ring and pinch the ends to seal.

In a small bowl, whisk the egg with a splash of water or milk. Brush each bagel with the egg wash. Add desired toppings.

Preheat air fryer to 300°F. Spray or line the basket with parchment paper.

Air fry the bagels in a single layer for 15–17 minutes, or until golden brown and puffed. Check around the 10-minute mark, as air fryer times may vary.

Let cool for at least 15 minutes before slicing and serving. Enjoy warm or toasted!
