Preheat the oven to 400°F. Wearing gloves, slice the jalapenos in half lengthwise. Using a small spoon, scoop out the seeds and membranes. In a bowl, mix cream cheese, bacon jam, garlic powder, cheddar cheese, butter and chives (if using). Fill jalapenos with the cheese mixture. Place on a baking pan and bake 18-22 minutes or until golden. Cool 5-10 minutes before serving.
