Core apples, being careful not to cut through bottom. Remove peel from stem end (approximately 1 inch). Mix cinnamon and sugar. Place apples in a shallow baking dish. Spoon cinnamon-sugar mixture into the center of each apple. Cover with plastic wrap. Microwave at high (100%) until apples are tender, 6 to 8 minutes. Serve warm or chilled. Makes 6 servings.
