Preheat your oven to 375°F and line a baking sheet with parchment paper.
In a large mixing bowl or your mixer with dough hook, combine the flour, baking powder, and salt.
Add the yogurt and stir until a shaggy dough forms. Dough will be sticky.
Turn the dough onto a lightly floured surface and knead just until smooth, about 1–2 minutes.
Divide the dough into 4 equal pieces.
To shape: Form a ball and poke your finger through it, stretching the hole using your fingers a bit larger than you would like it, as the hole will close as it bakes. Alternatively you can roll each piece into a rope and pinch the ends together to form a bagel.
Place the bagels on the prepared baking sheet.
Brush the tops with the beaten egg wash and sprinkle with your favorite toppings.
Bake for 30 minutes, or until the bagels are puffed and beautifully golden brown.
Allow them to cool for a few minutes before slicing and serving.
