Step 1

Preheat oven to 400-degrees F.

Step 2

Wash the sweet potato and rub it all over with the olive oil. Poke it a couple of times on TOP with a fork so that it doesn't blow up while baking. Do NOT wrap it in aluminum foil! Bake in the oven at 400-degrees F. for about one hour.

Step 3

In a small bowl, melt the butter in the microwave for a few seconds, reserving two slices for topping later, and then blend in the brown sugar.

Step 4

When the potato has baked to the point that the pulp is tender, and after it has cooled a bit, carefully cut out the top and scoop out the pulp into a medium mixing bowl. Save the intact potato skin! Mash the potato pulp with a fork and add in the butter/brown sugar mix.

Step 5

Spoon the potato pulp back into the potato skin and top with the two slices of butter, the sugar, and the cinnamon.

Step 6

Place the potato on a cookie sheet and BROIL on high for about 6 minutes. Watch it carefully so that it doesn't burn the top.

Step 7

Serve hot.
