Preheat oven to 400°F. Mix flour, sugar, baking powder, cinnamon and salt in large bowl; set aside. Mix cereal and milk in another bowl; let stand 3 minutes. Stir in egg and oil; mix well. Add to flour mixture; stir just until moistened. (Batter will be lumpy.)
Spoon batter into paper-lined medium muffin pan, filling each cup 2/3 full. Roll 12 (4-inch square) pieces of foil into balls. Tuck 1 between paper liner and side of each muffin cup to resemble heart shape.
Bake 20 minutes or until golden brown. Serve warm. Makes 12 servings, 1 muffin each.
