Prepare the Jalapeños:
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil.
Halve the jalapeños lengthwise and carefully remove the seeds and membranes using a small spoon or melon baller.
Make the Filling:
In a mixing bowl, combine cream cheese, cheddar cheese, mozzarella cheese, garlic powder, smoked paprika, salt, and pepper.
Mix until well blended. If using bacon, stir it into the filling.
Stuff the Jalapeños:
Spoon the cheese mixture into each jalapeño half, filling them generously.
Add the Topping:
In a small bowl, mix the panko breadcrumbs with the melted butter until evenly coated.
Sprinkle the breadcrumb mixture over the stuffed jalapeños for a crispy topping.
Bake:
Arrange the jalapeños on the prepared baking sheet, cut side up.
Bake for 15-20 minutes, or until the breadcrumbs are golden and the cheese is bubbling.
Serve:
Let the poppers cool slightly before serving.
Pair with ranch or your favorite dipping sauce for an extra kick of flavor.
