In a bowl, mix flour, baking powder, and salt.

Add Greek yogurt and mix until a shaggy dough forms.

Knead gently until smooth, adding a little flour if too sticky.

Divide dough into 4 equal portions.

Roll each into a ball, then poke a hole in the center and shape into bagels.

Place on a lined baking sheet.

Brush tops with beaten egg and add desired toppings.

Bake at 375°F (190°C) for 18 to 22 minutes until golden brown.

Let cool for 10 minutes before slicing and serving.
