Spread the outside of each slice of bread with butter.
Add the cream cheese, sour cream, cheddar, jalapenos, and garlic powder to a small bowl and stir well to combine.
Arrange two slices of bread butter side down and top with the cheese mixture. Place the remaining slices of bread over the top, butter side up.
Place the sandwiches in your air fryer basket and air fry at 360 degrees for 4 minutes. Flip the sandwiches over and continue cooking for 3-4 minutes or until bread is golden brown and toasted.
Let set 1 minute before serving.
Notes
We like to use jarred pickled jalapenos for a more mild and tangy flavor. Using fresh jalapenos will result in a spicier sandwich.
