Poke potatoes with a fork, spray lightly with oil (optional) and bake at 425 degrees until soft enough to pierce with a knife. This will depend on the size of your potatoes but should take about 40 minutes.
Let potatoes cool.
Slice potatoes in half length-wise and scoop out the potato until just a thin layer remains.
Melt butter in a small bowl and mix in spices.
Brush inside and outside of potato skins with butter.
Place cut-side down on a baking sheet lined with foil.
Bake at 400 degrees F for 10 minutes.
Remove from oven, flip them over and fill with shredded cheese and diced bacon.
Bake 5 more minutes. Remove and top with green onions before serving.
