Preheat the oven to 450 and line a jelly roll pan with aluminium foil.
Put the cream cheese and Cheddar cheese in a small resealable bag and knead. until cheeses are well-combined. Cut a corner of the bag and use it to pipe a generous amount of cheese onto each jalapeno half. Wrap a piece of bacon around each half. Place the peppers on a rack in the jelly roll pan and bake for 20 minutes. If you prefer them on the grill use a toothpich to hold the bacon in place and grill until the bacon is the desired crispness.
