01 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
02 - Pierce potatoes with a fork and bake directly on the oven rack for 45-50 minutes, or until tender. Allow to cool slightly.
03 - While potatoes are baking, cook bacon in a skillet over medium heat until crisp. Drain on paper towels and crumble.
04 - Cut each cooled potato in half lengthwise. Carefully scoop out most of the flesh, leaving approximately ⅓ inch thick shell. Reserve the scooped potato flesh for alternative culinary applications.
05 - Whisk together melted butter, garlic powder, salt, and black pepper. Brush the interior and exterior of each potato skin with this seasoning mixture.
06 - Arrange potato skins cut-side up on the prepared baking sheet. Initially bake for 10 minutes. Subsequently, flip the skins and bake for an additional 5 minutes.
07 - Evenly distribute shredded cheddar cheese and crumbled bacon onto the interior of each potato skin. Return to the oven and bake for 5-7 minutes, until the cheese is completely melted and bubbly.
08 - Remove from the oven. Garnish with sliced scallions. Serve immediately with ranch dressing for dipping.
