   2      c.            sifted all-purpose flour
   3      tsp.          baking powder
     1/2  tsp.          baking soda
     3/4  tsp.          salt
   1      dash          cinnamon
     1/2  c.            melted butter
   1      c.            boiled -- peeled, mashed
                        sweet potatoes
     2/3  c.            buttermilk

Preparation:

Sift flour, baking powder, baking soda, salt, brown sugar and cinnamon; set aside. Using a medium-size bowl beat melted butter into sweet potatoes. Add dry ingredients, stirring in a little at a time, alternate with buttermilk. Mix just well enough to moisten. Form into a ball, turn out on a lightly floured board. Lightly pat top side with flour since batter is sticky. Roll out to 1/2 to 3/4-inch thickness with a floured rolling pin. Cut with a floured biscuit cutter. Bake in preheated 450 degrees oven for about 20 to 25 minutes.
