Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large mixing bowl, combine all-purpose flour, baking powder, and salt. Whisk until well blended.

Fold in the thick Greek yogurt into the dry ingredients and mix until a dough forms.

On a floured surface, divide the dough into four equal portions, roll into balls, and poke holes in the center to form bagels.

Brush each bagel with a beaten egg and sprinkle with desired toppings.

Bake the bagels for 22-25 minutes until golden brown.

Let them cool on a wire rack for about 10 minutes before serving.
