Ingredients
- 1 1/2 cups whole wheat pastry flour
- 1 cup coarse graham cracker crumbs, divided
- 1/2 cup sugar
- 1 teaspoon baking powder
- 1 teaspoon baking soda

- 1 (3/4-pound) sweet potato, peeled and grated
- 3 tablespoons butter, at room temperature
- 1 (6-ounce) container plain nonfat yogurt
- 2 eggs
- 1/4 cup finely chopped pecans or walnuts
Directions
-
Preheat oven to 375°F. Line a 12-muffin tin with cupcake papers; set aside.

In a large bowl, whisk together flour, 3/4 cup crumbs, sugar, baking powder, baking soda and salt. Add sweet potatoes and toss until well coated; set aside.

In a second large bowl, vigorously whisk together butter and yogurt for 30 seconds. Add eggs one at a time, whisking well after each addition.
