Step 1

Preheat oven to 425 degrees. Spray a baking sheet with nonstick spray.

Step 2

Pierce potatoes several times with a fork. On a microwave-safe plate, microwave for 15 minutes, until potatoes are soft.

Step 3

Once cool enough to handle, slice each potato in half lengthwise. Carefully scoop out the insides, leaving about 1/4 inch inside the skin. Discard the potato pulp (or reserve for another use).

Step 4

Place hollow shells on the baking sheet. Sprinkle with cinnamon, nutmeg, and salt.

Step 5

Bake until the edges begin to crisp, about 10 minutes.

Step 6

Top with brown sugar and marshmallows. Bake until marshmallows puff up and lightly brown, 3 - 4 minutes. Enjoy!
