Add cottage cheese to a food processor and process until just blended. The texture should be smooth with several small chunks remaining, similar to the texture of greek yogurt.

In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt. Add the blended cottage cheese and egg. Stir well with a spoon. If the dough feels too sticky, add 1-2 tbsp flour at a time.

Generously flour hands. Take ~1 ½ tbsp dough at a time and carefully roll into balls. Transfer to a plate. 

Take ~1 tsp cream cheese and roll into a small ball. Gently flatten one of the dough balls and press cream cheese into the center, fold the dough over the filling, and re roll into a ball with floured hands. Repeat with remaining dough balls.

Whisk egg with 1 tbsp water to make the egg wash. Brush egg wash over the dough balls and sprinkle over bagel seasoning.

Preheat air fryer. Coat basket with non-stick cooking spray. Place balls in air fryer, trying not to overcrowd the basket. Spray with non-stick cooking spray. Air fry for 7-8 minutes at 375°F.

Cool bagel bites for 5 min before serving.
