Preheat the oven to 350ºF. Place a raised rack on a baking sheet and coat the potatoes with 2 tablespoons of extra virgin olive oil. Season lightly with salt. Place the potatoes on the rack and transfer to the oven for 45 minutes to 1 hour or until fork-tender. Remove from the oven and let cool.
Cook the bacon:
Place the sliced bacon in a large skillet. Turn the heat to medium and cook, turning often, for 8 to 10 minutes until the fat renders and the bacon is browned and crispy. Transfer to a paper towel-lined plate.
Make the filling:
Once the potatoes are cool enough to handle, halve them lengthwise. Scoop out the flesh into a large bowl and reserver the skins.
Season the potatoes with 1 teaspoon salt. Add the milk, sour cream, and butter and mix until combined. You can use a potato masher or an electric hand mixer.
Add the scallions, jalapeño, garlic powder, and black pepper. Taste and adjust the seasonings to your preference.
Bake the potatoes:
Fill the potatoes with the filling. Transfer to the oven for 25 to 30 minutes. Remove from the oven and turn on the broiler.
Finish the potatoes:
Place half a slice of Andrew & Everett American Cheese on top of each potato. Transfer to the broiler for 2 to 3 minutes until the cheese is golden brown and melted.
To serve:
Serve the potatoes warm with a few additional minced scallions on top. Enjoy!
