Prepare the Breadcrumb Mixture: In a large bowl, mix together the breadcrumbs, shredded cheddar cheese, eggs, ½ teaspoon of salt, and ½ teaspoon of pepper. Stir these ingredients until they are well combined, creating a cohesive mixture.

Form the Bases: Spray a muffin tin with nonstick cooking spray. Take a heaping tablespoon of the breadcrumb mixture and place it into each muffin cup. Firmly press the mixture into the pan to create a well in the center of each cup. This will form the base of your jalapeño bites.

Mix the Filling: In another large bowl, combine the cream cheese, cooked and crumbled bacon, diced jalapeños, the remaining ½ teaspoon of salt, and the remaining ½ teaspoon of pepper. Mix these ingredients thoroughly to ensure a consistent flavor throughout.

Preheat the Air Fryer: Set your air fryer to 340°F. Let it preheat, which ensures that your jalapeño bites will cook evenly and achieve a nice texture.

Assemble the Jalapeño Bites: Spoon about 2 tablespoons of the cream cheese mixture into each breadcrumb-lined cup in your muffin tin. Make sure the filling is evenly distributed. Then, sprinkle a bit more shredded cheddar cheese on top of each filled cup, and add a slice of jalapeño to the top for an extra kick.

Cook in the Air Fryer: Carefully place the muffin tin in the air fryer. Bake the jalapeño bites for 5-10 minutes. Keep an eye on them and remove them once the tops are golden brown and the cheese has melted.

Serve and Enjoy: Once done, let the jalapeño bites cool for a few minutes before removing them from the muffin tin. Serve warm as a deliciously spicy and cheesy snack or appetizer.
