Preheat the oven to 375°F (190°C), or the air fryer to 330°F (165°C).

In a bowl, mix the flour, baking powder, and salt. Stir in the Greek yogurt until a dough forms, then knead briefly until smooth.

Divide the dough into 4 equal parts. Roll into balls, then poke a hole in the center and stretch into a bagel shape.

Brush with egg wash if using, then top with your seasoning of choice.

Oven: bake for 22-25 minutes until golden and cooked through. Air Fryer: cook for 10-12 minutes, checking at 10 minutes.
