Granola Streusel-Topped Sweet Potatoes

I found this recipe in a Betty Crocker Thanksgving book from November 2005. It is a little different from the other one that I usually do, so I thought I would give it a try. I love sweet potatoes, but my husband is a mashed potatoes kind of guy so we will be having both :)

Ingredients:
6 meduim dark-orange sweet potatoes, peeled, cut into 1-1/2 pieces (7 to 8 cups)
1/2 cup heavy whipping cream
2 tablespoons butter or margarine
1/4 cup maple syrup
1/2 teaspoon salt
4 Nature Valley maple-brown sugar crunchy granola bars
2 (more) tablespoons butter, melted

1. In 4-quart saucepan, place potato pieces and add enough water to cover. Heat to boiling; reduce to medium-low. Cook uncovered 15 to 20 minutes or until tender. Drain and return to saucepan.
2. Heat oven to 350 degrees. Spray 8" sq. glass baking dish with cooking spray. To potatoes, add whipping cream, 2 tablespoons butter, the maple syrup, and solt. Mash with potato masher or electric mixer until smooth. Spoon into baking dish. In small bowl, mix crushed granolabars and 2 tablespoons melted butter; sprinkle over potatoes.
3. Bake uncovered 25 to 30 minutes or until thoroughly heated and topping is crisp. 10 servings (1/2 cup each).
