01 - Preheat oven to 375°F. Line a baking sheet with parchment paper.
02 - Combine cottage cheese and Greek yogurt in a large bowl. Mix until smooth and fully incorporated.
03 - Add flour, whey protein powder, baking powder, and salt to the bowl. Stir until a shaggy dough forms.
04 - Turn dough onto a floured surface. Knead lightly for 2-3 minutes until just combined. Avoid overworking the dough.
05 - Divide dough into 4 equal pieces. Roll each into a ball, poke a hole through the center, and gently stretch into a bagel shape.
06 - Place shaped bagels on the prepared baking sheet. Brush tops with beaten egg for a golden finish.
07 - Bake for 23-25 minutes until golden brown and firm to the touch.
08 - Let cool slightly. Top each bagel with cottage cheese, chives, and black pepper. Serve warm or at room temperature.
