Preheat oven to 375°F. Spray a metal baking pan with nonstick oil.
Combine the flour, baking powder, and salt in a bowl and mix. Add the yogurt and mix well with a large spoon.
If adding flavoring to the dough of the bagels (sundried tomato basil, blueberry, or other) add to the dough now.
Once the dough starts to form a larger ball, dust a surface with flour and knead the dough until it is no longer sticking to your hands. Add flour as needed to achieve the right consistency.
Divide the dough into 4 equal parts. Roll into a ball and then stick finger through the middle to create the hole of a bagel.
After placing bagels on the metal pan, brush each bagel with olive oil. If adding toppings, sprinkle on bagels.
Bake bagels on the middle oven rack for 25 minutes.
