2½ cups hot mashed potatoes
1 cup milk
3 beaten eggs
2 Tablespoons melted butter
2 cups sugar
5 cups flour
2 Tablespoons baking powder
(Note: I used King Arthur self rising flour and omitted the baking powder)
Mix everything together except flour. Mix flour in slowly (one cup or so at a time).
Divide the dough in half or thirds. Roll to 1/4 to ½ inch thick. Cut with a donut cutter or use a knife to cut into triangular shaped pieces. Deep fry in hot fat or oil (between 325 and 350 degrees--use a thermometer-- keep a lid for the pan handy in case it catches fire, and keep water far away from hot oil) until done.
Coat with powdered sugar, if desired, by shaking in a paper bag filled with a generous amount of confectioners sugar.
