Rinse and gently scrub potatoes. Cook the potatoes in boiling water until fork tender, about 15 to 20 minutes.
Heat oven to 450 degrees.
While the potatoes are boiling, in a small mixing bowl combine the butter, black pepper, garlic and Old Bay Seasoning. Microwave until butter is melted and mix together well.
Drain the potatoes and gently pat dry.
Mix the olive oil and salt and pepper in a medium sized bowl. Roll each potato in the olive oil mixture until completely coated.
Place the potatoes on a rimmed cookie sheet and gently flatten with the bottom of a drinking glass.
With a pastry brush coat each smashed potato with the butter mixture.
Bake for about 5 minutes. Then pull out of oven and top all of the potatoes using 1 tablespoon of chives. Then sprinkle cheese over all the potatoes, then sprinkle the other tablespoon of chives evenly over the potatoes.
Bake in the oven for another 5 to 6 minutes.
