Deseed the peppers. Preheat the oven to 400°F (200°C). Slice the jalapeño peppers in half, and use a small spoon to scoop out the seeds and membrane. Place them on a baking sheet and set aside.
Make the filling. To a medium mixing bowl, add the cream cheese, cheddar cheese, 4 strips of cooked and crumbled bacon, chives, garlic, salt, and pepper. Stir together until well combined.
Fill the peppers. Use a spoon to scoop a portion of the filling and fill the jalapeño peppers.
Bake the peppers. Bake the jalapeño peppers for 15 to 20 minutes, until they're lightly golden on top. Garnish the tops with the remaining 2 pieces of cooked and finely crumbled bacon, and extra chives. Serve while warm.
