01 - Place eggs in a saucepan and cover with cold water by about 1 inch. Bring to a rolling boil over medium-high heat, then reduce heat to low, cover, and simmer for 10 minutes.
02 - Drain the hot water and immediately transfer eggs to an ice bath. Let them cool for at least 5 minutes, then gently peel off the shells.
03 - Slice each egg in half lengthwise. Carefully scoop the yolks into a medium mixing bowl and set the whites aside on a serving platter.
04 - Mash the yolks thoroughly with a fork. Add cream cheese, mayonnaise, sour cream, Dijon mustard, and garlic powder. Stir until completely smooth and creamy.
05 - Gently stir in the diced jalapeño, chopped bacon, shredded cheddar cheese, and chives. Season with salt and pepper to taste.
06 - Spoon or pipe the yolk mixture evenly into each egg white half, mounding slightly above the rim.
07 - If using panko, toast the breadcrumbs in a dry skillet over medium heat, stirring frequently, until golden brown, about 2 to 3 minutes. Sprinkle over the filled eggs.
08 - Top with additional crumbled bacon and thin jalapeño slices. Refrigerate until ready to serve. Serve chilled.
