Spicy Sweet Potato Puff - cooking recipe

Ingredients

Puff
2 medium sweet potatoes, cooked and peeled
1/2 cup low-fat milk
1/3 cup brown sugar
2 eggs
2 tablespoons butter
1/2 teaspoon nutmeg
1/2 teaspoon cinnamon
1/2 - 1 whole chipotle chile in adobo, minced
Topping
2 tablespoons butter, melted
1 1/4 cups walnuts or 1 1/4 cups pecans, chopped
1/4 cup brown sugar, firmly packed

Preparation

Preheat oven to 400 degrees.
In a large mixing bowl (I use an electric mixer), mash the sweet potatoes.
Add the remaining ingredients and blend until smooth and creamy.
Spread mixture into a greased 9x9 inch casserole.
Bake for 20 minutes or until set.
While puff is baking, combine ingredients for topping.
After 20 minutes, or once puff has set, spread topping over puff and bake for ten more minutes.
