01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Slice jalapeños in half lengthwise. Remove seeds and membranes for milder heat or leave some for extra spice.
03 - In a mixing bowl, blend cream cheese, cheddar, Monterey Jack, minced garlic, smoked paprika, black pepper, and salt until smooth.
04 - Fill each jalapeño half with the cheese mixture, mounding slightly above the edges.
05 - Beat eggs in a shallow bowl. In another bowl, combine panko breadcrumbs, paprika, and optional cayenne pepper.
06 - Dip each stuffed jalapeño half into the beaten eggs, then roll in the breadcrumb mixture to fully coat.
07 - Place coated poppers on the prepared baking sheet, filling side up. Bake for 18 to 20 minutes until golden brown and bubbly.
08 - Remove from oven and garnish with crumbled bacon and fresh chives if desired. Serve warm.
