Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
In a bowl, combine the cottage cheese, Greek yogurt, and 1 egg. Mix until smooth.
In another bowl, whisk together the flour, baking powder, and salt.
Add the dry ingredients to the wet mixture. Stir until a sticky dough forms.
Lightly flour a surface and gently knead the dough for about 1 minute, just until it comes together.
Divide the dough into 6 equal pieces. Shape each into a ball, then poke a hole in the center to form a bagel shape.
Place the bagels on your prepared baking sheet. Brush with the beaten egg.
Sprinkle your desired toppings over each bagel.
Bake for 25–28 minutes, or until golden brown and firm to the touch.
Let them cool completely on a wire rack before slicing or storing.
