Preheat the oven to 400 degrees. Coat a baking sheet with cooking spray.
Boil the potatoes in water for 10-15 minutes or until fork tender. Place on the prepared baking sheet. Place the potatoes on a paper towel and with another towel on top of the potatoes, gently press down with your hand to smash them. You can also use a potato masher but I find that my hand does a better job. Place the smashed potatoes on the baking sheet and drizzle with olive oil, sea salt and freshly cracked pepper, to taste.
Place into the oven and bake for 10-15 minutes then carefully flip them over and bake for an additional 10 minutes. Remove from the oven and place a bit of butter on each potato followed by some shredded sharp cheddar, a dollop of sour cream, some bacon bits, and green onions. Serve immediately. Enjoy.
