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 completely smooth and homogeneous.
03 - Add whole wheat flour, whey protein powder, baking powder, and salt to the wet mixture. Stir until a shaggy, sticky dough forms.
04 - Turn dough onto a lightly floured surface. Knead gently for 2-3 minutes until just combined. Avoid overworking to maintain texture.
05 - Divide dough into 4 equal portions. Roll each into a smooth ball, press a thumb through the center, and gently stretch into an even ring shape.
06 - Place shaped bagels on the prepared baking sheet. Brush tops generously with beaten egg for a golden, shiny finish.
07 - Bake for 23-25 minutes until deeply golden brown and firm to the touch. Rotate pan halfway through for even browning.
08 - Let cool for 5 minutes. Spread cottage cheese generously over each bagel. Garnish with fresh chives and cracked black pepper.
