Slice each jalapeño in half lengthwise and carefully remove seeds and membranes with a paring knife or spoon. Set aside.
In a mixing bowl, combine softened cream cheese, shredded cheese, buffalo sauce, garlic powder, and paprika. Mix until smooth and well integrated, creating a creamy, tangy filling.
Use a spoon or piping bag to generously fill each jalapeño half with the cheese mixture, pressing it in so it stays in place.
If using bacon, wrap each stuffed pepper with a half strip and secure with a toothpick to help contain the filling during baking.
Arrange the stuffed peppers on a baking dish lined with parchment or lightly greased. Bake at 200°C (390°F) for 15-20 minutes, until the cheese is bubbly and the peppers are tender with blistered, slightly charred skin.
Remove from the oven and brush the tops of the peppers with extra buffalo sauce for added flavor and heat. Let rest for 5 minutes to allow the cheese to set slightly.
Serve the Buffalo Jalapeño Poppers warm, garnished with chopped herbs if desired, enjoying the messy, spicy, cheesy bites that capture the essence of summer cookouts.
