Preheat your oven to 400°F.
Using a sharp knife, carefully create a pocket in the chicken breast by slicing horizontally, ensuring not to cut all the way through.
In a small bowl, mix the cream cheese, finely chopped jalapeño, garlic powder, salt, and pepper until well combined.
Stuff the chicken breast pocket with the creamy jalapeño mixture.
Wrap a slice of bacon around the outside of the chicken breast, securing it with toothpicks if needed.
Lightly spray the chicken with olive oil cooking spray and season with additional salt and pepper if desired.
Place the stuffed chicken on a baking sheet and bake in the preheated oven for about 25-30 minutes, or until the chicken is thoroughly cooked and the bacon is crispy.
Remove from the oven, let it rest briefly, then remove toothpicks before serving.
