Slice the jalapenos in half lengthwise, and remove all of the seeds with a spoon.
In a medium bowl, add the cream cheese, cheddar, bacon, and garlic powder. Mix until completely combined.
Fill the jalapeno halves with the cheese mixture.
Preheat your air fryer to 385 degrees for 1 minute.
Arrange jalapenos in a single layer in the air fryer basket, and air fry for 6-7 minutes, or until the cheese is bubbly. You may have to air fry in two batches, depending on the size of your air fryer.
Remove from air fryer, and serve warm.
Notes
Use gloves if you don't want to accidentally touch your eye with jalapeno juice (LOL!)
