1. In a large bowl, mix flour, powdered milk, salt, sugar and baking powder. Add warm water and stir to combine (mixture will be wet). On a well-floured surface, pat out dough until 1/2 to 3/4 inch thick. Cut into pieces of whatever size youd like your scones to be.
2. Fill a pan 4 to 5 inches high with vegetable oil and heat to 365 degrees on a deep-fat fry thermometer. (This should be hot enough so that when you add scones they start to bubble right away and float.) Fry dough pieces in batches until they turn light golden brown, about 3 to 4 minutes per batch. Make sure oil gets back up to temperature before adding more dough.
3. Serve with optional toppings. (My grandma always put out an assortment of jellies and jams, honey and heaps of butter.)
