Apple pie
Vanilla ice cream or frozen yogurt
Powdered cinnamon

Put a generous quantity of vanilla ice cream or frozen yogurt into a large mixing bowl. Stir the ice cream with a spoon, all while stirring in powdered cinnamon. Keep this up until the ice cream is strongly flavored with cinnamon and reduced in texture to a smooth paste like soft serve ice cream. Then spread a 1/2 inch of this mixture over the slice of hot apple pie.
