Preheat the oven to 375°F. Coat a sheet-pan with cooking-spray.
Put the cream-cheese, cheddar-cheese, jalapenos and garlic-powder in a bowl and stir to blend.
Cut a deep-pocket to each chicken-breast, taking care to not cut all of the way through the other side.
Fill out the pocket of each chicken-breast with all the cream-cheese mix.
Season the outside of the chicken-breasts with pepper and salt to taste.
Wrap each chicken-breast closely with 2-slices of bacon and put the chicken onto the sheet-pan.

Allow the chicken rest for 5minutes. then slice and serve.
