01 - Place eggs in a saucepan and cover with cold water by 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 cool for 5 minutes, then gently peel off the shells.
03 - Slice each egg in half lengthwise. Carefully scoop out the yolks into a medium mixing bowl, keeping the egg white halves intact.
04 - Mash the yolks thoroughly with a fork. Add cream cheese, mayonnaise, sour cream, Dijon mustard, and garlic powder. Blend until the mixture is completely smooth and creamy.
05 - Gently stir in the diced jalapeño, chopped bacon, shredded cheddar cheese, and chives. Season with salt and freshly ground black pepper to taste.
06 - Spoon or pipe the yolk mixture generously back into each egg white half, mounding slightly above the rim.
07 - If using, toast panko breadcrumbs in a dry skillet over medium heat, stirring constantly, until golden brown. Sprinkle evenly over the filled eggs.
08 - Top with extra crumbled bacon and thin jalapeño slices. Refrigerate for at least 15 minutes before serving chilled.
