Preheat the oven to 375°F (190°C).
Prepare the jalapeños by cutting them in half lengthwise and removing the seeds and membranes.
In a mixing bowl, combine the softened cream cheese, cheddar cheese, crumbled bacon, garlic powder, onion powder, and black pepper.
Spoon the cheese and bacon mixture into each jalapeño half, packing it generously.
Place the filled jalapeños on a baking sheet lined with parchment paper.
Bake in the preheated oven for about 20-25 minutes, or until the cheese is bubbly and the jalapeños are tender.
If desired, sprinkle with fresh chives before serving for a pop of color and flavor.
