Preheat your air fryer basket to 375°F (190°C) for 3–5 minutes to ensure crisp results.
Halve and seed jalapeños, removing membranes for milder heat while keeping the pepper firm.
Mix cream cheese with shredded cheddar and spices (garlic powder, smoked paprika) until smooth and well combined.
Fill each jalapeño half moderately with the cheese mixture, avoiding overfilling to prevent leaks.
Dip each stuffed pepper in beaten eggs, then coat evenly with panko crumbs, repeating for a double layer.
Spray poppers lightly with oil and air fry in a single layer for 6–8 minutes, flipping halfway, until the outside is golden brown and the cheese inside is melted but contained.
