6 TBSP butter, softened
2/3 cup sugar
1 tsp vanilla extract
1 3/4 cup flour
1 1/2 tsp baking powder
1 tsp cinnamon
1/2 tsp nutmeg
1/2 tsp salt
2/3 cup evaporated or regular milk
1 1/2 cups peeled finely shredded sweet potato
2/3 cup chopped walnuts or pecans
In a large mixing bowl with hand-held electric mixer on medium speed, beat butter and sugar until light and fluffy. Beat in egg and vanilla until well blended.
In a separate bowl, combine flour, baking powder, cinnamon, nutmeg, and salt. Stir into the butter mixture alternately with milk, mixing just until dry ingredients are moistened. Stir in sweet potato and chopped nuts. Spoon batter into greased muffin cups, filling about 2/3 full.
Bake at 375° for 25 to 30 minutes, or until centers spring back when pressed with fingertip. Cool in pan on rack for 5 minutes. Remove from pan and serve muffins warm. Makes about 1 dozen sweet potato muffins.
