Preheat oven to 400°F.
Slice each jalapeno pepper in half lengthwise, removing seeds and membranes.
In a bowl, combine cream cheese, cheddar cheese and garlic powder.
Stuff each pepper with the cheese mixture. Wrap a half bacon slice around each pepper and secure with a toothpick.
Place peppers on a baking sheet and bake for 20 to 25 minutes until the cheese is starting to brown on top.
Turn the broiler on and broil for a few minutes to get the bacon crispy. Enjoy warm.
