Prep the air fryer: Preheat to 360°F (182°C) for 3–5 minutes. A warm basket helps the bites crisp faster.

Mix the filling: In a bowl, stir together cream cheese, mozzarella, and any optional add-ins. Keep it thick so it doesn’t leak.

Portion the dough: If using pizza dough, cut into 16 even pieces. If using biscuit dough, split each biscuit in half horizontally to make thinner rounds.

Fill and seal: Flatten each piece into a small round. Add about 1 tablespoon of filling to the center. Pull the edges up and pinch to seal tightly. Roll gently into a smooth ball with the seam underneath.

Make the egg wash: Whisk the egg with milk or water. Brush each ball lightly. This is your “glue” for the seasoning.

Season generously: Roll or sprinkle each ball in everything bagel seasoning, coating the top and sides. Don’t overdo the bottom—it can burn.

Load the basket: Lightly spray the air fryer basket with olive oil. Place the bites seam-side down with space between them. Work in batches if needed.

Air fry: Cook at 360°F (182°C) for 7–10 minutes, until golden brown and slightly puffed. Start checking at 7 minutes. If using biscuit dough, they may brown faster.

Rest briefly: Let them sit for 2–3 minutes. The filling sets and won’t ooze out when you bite in.

Serve: Enjoy warm with your favorite dip, or on their own. They’re great plain because the seasoning carries a lot of flavor.
