Preheat your air fryer to 370°F (190°C) for about 5 minutes.
While the air fryer is heating, prepare the jalapenos by slicing them in half lengthwise and removing the seeds and membranes (use gloves to protect your hands from the spice).
In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, crumbled bacon, garlic powder, onion powder, salt, and black pepper. Mix well until all ingredients are thoroughly combined.
Stuff each jalapeno half generously with the cheese and bacon mixture.
Lightly spray the air fryer basket with cooking spray or brush it with olive oil to prevent sticking.
Place the stuffed jalapenos in the air fryer basket in a single layer, making sure they are not overcrowded.
Cook the jalapeno poppers in the air fryer for 10-12 minutes or until the cheese is melted and bubbly and the jalapenos are tender.
Carefully remove the poppers from the air fryer and let them cool slightly before serving.
Optional: Garnish with chopped green onions or cilantro for an added flavor boost.
