Preheat your oven to 400°F (higher than the original recipe for faster cooking and better browning). Wash the russet potatoes thoroughly and prick them all over with a fork to allow steam to escape. Bake directly on the oven rack for 40-50 minutes until they're tender when pierced with a knife. While the potatoes cook, prepare your mise en place: cook the bacon strips until crispy, crumble them, seed and finely dice the jalapeño, shred the cheddar cheese, and slice the green onions. I like to cook the bacon first so it cools while everything else comes together—this makes it easier to crumble and keeps your hands clean.

Once potatoes are cool enough to handle, cut each in half lengthwise and carefully scoop out the insides, leaving about ¼-inch of potato flesh as the shell to maintain structure. Place the scooped potato into a mixing bowl. Add the softened cream cheese, butter, milk, salt, pepper, and garlic powder to the bowl and mash everything together until smooth and creamy. Fold in the diced jalapeño, three-quarters of the crumbled bacon (reserving the rest for garnish), and about three-quarters of the shredded cheddar, stirring gently to combine. I always reserve some bacon and cheese for topping because it creates a more attractive presentation and ensures every bite has those crunchy, cheesy elements.

Arrange the hollowed potato halves on a baking sheet, cut-side up. Divide the filling mixture evenly among the potato shells, mounding it slightly in the center. Top each stuffed potato with a sprinkle of the remaining shredded cheddar cheese and a light dusting of smoked paprika. Place in the preheated 400°F oven and bake for 15-18 minutes until the tops are golden and the filling is heated through.

Remove the twice-baked potatoes from the oven and let them rest for 2-3 minutes. Top each potato with a dollop of sour cream, the reserved crumbled bacon, fresh sliced green onions, and a few jalapeño slices for color and heat. Serve immediately while still warm.
