Add the flour to a medium bowl and combine it with the baking powder. Add a pinch of salt for extra flavor.

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

Turn the bagel dough onto a well-floured surface and knead it with your hands for 1-2 minutes until it forms a semi-smooth ball of dough.

Divide the bagel dough into 4 equal sections, roll each into a 6-7 inch log, and connect the ends to form bagels.

Crack and whisk the egg in a small bowl, brush the egg lightly all over each bagel, and add toppings if desired.

Preheat the air fryer to 300°F and spray or line the basket with cooking spray or parchment paper.

Place the bagels in an even layer into the air fryer. Cook for 15-17 minutes until golden, checking at 10 minutes.

Once the bagels are golden brown and light and fluffy, remove them from the air fryer and let them cool for at least 15 minutes before slicing.
