I found this recipe at http://www.noblepig.com which is “The Official Food Blog of Noble Pig Vineyard and Winery”. It says that this recipe was adapted from “Cuisine at Home”. We got a lot of sweet potatoes in the last few Bountiful Baskets so I thought I’d experiment and try making some out of the ordinary things with them. This is experiment #1 which smelled so tasty while baking.
for the muffins:
2 1/2 cups flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1/4 teaspoon baking soda
1/4 teaspoon ground nutmeg
1/3 cup buttermilk
1/3 cup milk
1/2 cup sweet potato puree (from 1 baked sweet potato) (I just cooked it in the microwave and then peeled it and mashed it up with a fork)
1 teaspoon vanilla
1 stick butter, room temperature
3/4 cup brown sugar
2 eggs
for the topping:
1/2 cup sugar
2 teaspoons cinnamon
1/4 teaspoon nutmeg
1 stick butter, melted
1 In a medium bowl, combine flour, baking powder, salt, baking soda and nutmeg.
2 In a large pouring vessel, combine milk, buttermilk, sweet potato puree and vanilla.
3 In a mixer bowl, cream butter and brown sugar until fluffy. Add eggs, 1 at a time, beating well after each addition. Alternately mix in dry and wet ingredients, starting and ending with dry; mix only until each addition is incorporated. Do not overmix.
4 Coat a muffin pan with nonstick spray and fill muffin pans 1/2 full. (I used liners and then just coated the tops of the muffins with cinnamon sugar rather than the entire muffin.) Bake at 350 for 20 – 25 minutes or until toothpick inserted in center comes out clean.
5 While muffins are baking, combine sugar, cinnamon and nutmeg in a shallow bowl. Melt butter in another small bowl.
6 When muffins are cool enough to handle, yet still warm, remove from pan and brush completely (or just tops) with butter and then roll in sugar mixture to coat.
I doubled the recipe and it made 3 dozen.

These sound great and I love the coating… lovely.
