We just had these on Thanksgiving up in Evanston; they were AMAZING. I might have to make them myself on Christmas. Obviously, you have to steam or bake the sweet potato ahead of time.
2 c. self-rising flour OR regular flour add 2 tsp. baking powder & 1/2 tsp. baking soda
3 Tbsp. brown sugar
1/4 tsp. cinnamon
1/8 tsp. allspice
7 Tbsp. butter
1 c. mashed sweet potatoes
6 Tbsp. milk
Combine dry ingredients in bowl. Cut in butter with forks until crumbly. Add milk and sweet potatoes; stir until moistened. Turn out dough and knead. Roll dough out to 1/2 inch thick. Cut and put on buttered sheet. Bake at 400 degrees for 12 min.
