Place the cottage cheese in a blender or food processor. Blend until completely smooth. This step helps create a soft and even dough.
In a medium bowl, combine the flour and baking powder. Stir well so everything is evenly mixed.
Add the blended cottage cheese to the bowl. Mix until a rough dough starts to form. Move the dough to a lightly floured surface and knead for about 1–2 minutes, just until smooth. The dough should feel soft and easy to handle, not too sticky.
Divide the dough into four equal portions. Roll each piece into a rope shape, then bring the ends together to form a circle. Leave a slightly larger hole in the center, as it will shrink during cooking.
Place the shaped bagels on a lined tray. Brush the tops with the beaten egg, then sprinkle with your preferred seasoning.
