Preheat your oven to 400°F/ 205°C.
Wear a pair of gloves to slice the jalapenos in half lengthways, then remove the seeds and ribs. In a mixing bowl, mix cream cheese, cheddar cheese, garlic powder, smoked paprika, and green onions.
In a separate bowl, add melted butter to Panko breadcrumbs and stir to combine. Fill the jalapeno halves with the cream cheese mixture, place them on a prepared baking sheet, and then top with the breadcrumbs. Bake until golden brown, approximately 18 - 20 minutes. Serve immediately and enjoy.
