Preheat oven to 400 degrees, or if need to bake other dishes at 350 degrees, use that temp. You must adjust baking time longer if you bake at a lower temp.
Wash and thoroughly dry each potato. Rub outside of potato lightly with butter and sprinkle lightly with kosher salt. Place potatoes on baking sheet and put into preheated oven and bake until a fork inserted into potato comes out easily and potato is soft.
In a medium bowl, combine 1 cup butter, brown sugar, and cinnamon well using a whisk. With a spoon, stir bacon bits, if using, into butter mixture. Set aside.
To serve, place potato on serving dish, cut down middle and, using a fork, fluff up potato inside shell. Place spoonful of topping on each half. Makes 16 potato halves. Enjoy!
