In a medium-sized bowl, combine the flour, baking powder, and salt.

Add in the Greek yogurt and mix the dough using a fork, your hands, or a rubber spatula until it’s wet but still slightly crumbly.

Turn the dough out onto a well-floured surface and knead it into a smooth ball.

Split the dough into 4 equal pieces.

Roll each piece into a 5-6 inch long, 3/4 inch wide log and form it into a circle, pinching the ends.

In a small bowl, combine the egg yolk with water and brush the mixture all over each bagel, then sprinkle on your desired toppings.

Preheat your air fryer to 350°F and spray the basket with olive oil.

Arrange the bagels in the air fryer in a single layer, about 2 inches apart. Cook for about 10 minutes, or until they’re golden and cooked through, checking around 8-9 minutes.

Remove the bagels from the air fryer and let them cool for 5-10 minutes before slicing and topping.
