Preheat the air fryer to 375 degrees F for 3 minutes.
In a mixing bowl, combine the ground beef, chopped bacon, breadcrumbs, egg, minced onion, minced garlic, 2 tablespoons bourbon, 3 tablespoons brown sugar, smoked paprika, salt, and black pepper. Mix until evenly blended.
Divide the mixture into 4 equal portions and shape each into a small loaf about 3 inches long.
Lightly coat the air fryer basket with cooking spray. Place the mini meatloafs in the basket without crowding them.
Air fry for 12 minutes. While they cook, stir together the remaining 1 tablespoon bourbon and 1 tablespoon brown sugar to make the glaze.
Brush the glaze over the top of each meatloaf. Continue air frying for 4 to 6 more minutes until the internal temperature reaches 160 degrees F and the edges look crisp.
