Combine the oil, maple syrup, ground cinnamon and bacon pieces in a bowl. Toss potatoes in the oil and syrup mixtures. Spread sweet potatoes on a sprayed baking sheet or one covered with parchment paper. Make sure your baking sheet has sides so drippings will not run over in your oven.
Bake in a preheated 350 degree oven for 35 to 40 minutes or until potatoes test done.
