I've made this doughnut recipe for years and the family always love it. You can either put a cinnamon/sugar topping on it or a glazed. I prefer the glazed. It has nice spices in it.
WONDERFUL DOUGHNUTS
4 eggs, beaten
2/3 c sugar
1/3 c milk
1/3 c melted butter
3 1/2 c flour
3 tsp baking powder
3/4 tsp salt
1/2 tsp cinnamon
1/4 tsp nutmeg
Combine the eggs and sugar; beat until light. Add milk and cooled butter. Sift together flour, baking powder, salt, cinnamon and nutmeg. Add to egg mixture; mix until smooth. Chill soft dough thoroughly in refrigerator. Roll dough out gently 1/3" thick. Cut with floured doughnut cutter; let stand 10 to 15 minutes. Heat salad oil 3 to 4: deep in a heavy kettle or deep-fat fryer to 375º. Transfer doughnuts to kettle of fat on a broad spatula, using care not to alter shape. (If possible, place board of doughnuts near frying kettle.) Slip into hot fat. Add only enough doughnuts at a time as can float on the fat or that can be turned easily. Turn doughnuts as they rise to the surface. Fry 2 to 3 minutes, or just until doughnuts are golden brown. Lift doughnuts from fat with kitchen fork (tines through center holes), using care not to prick them. Drain on paper towels in a warm place. Makes 30 doughnuts.
TOPPINGS:
To coat with sugar: Shake warm doughnuts, one at a time, in a paper bag containing 1/2 c granulated sugar or powdered sugar. To increase spicy flavor, stir 1 tsp cinnamon into the sugar and mix well before adding the doughnuts.
To glaze: Add 1/3 c boiling water to 1 c powdered sugar. Mix well. Dip warm doughnuts, one at a time, into the warm glaze.
Enjoy!
