Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish or use a parchment-lined sheet pan if you prefer a crisper edge.
Slice the chicken breasts in half lengthwise to create two thinner cutlets. This helps them cook evenly and absorb all the cheesy, spicy goodness.
In a bowl, mix the softened cream cheese, cheddar cheese, diced jalapeños, crumbled bacon, garlic powder, paprika, salt, and pepper until well combined.
Place the chicken pieces in the dish. Top each piece with a generous spoonful of the cheesy jalapeño mixture, spreading it to cover the surface. If you have extra filling, nestle it between the chicken pieces.
Bake for about 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is bubbling and lightly golden.
If you like a bit more browning on top, turn the broiler to high for 1-2 minutes at the end, watching carefully so it doesn’t burn.
Rest the dish for 5 minutes before serving. This helps the juices settle and makes every bite feel juicy and creamy.
