Can't find heart-shaped candies? Make gumdrop hearts: Flatten small red gumdrops with a rolling pin and use a tiny heart-shaped cookie cutter or the tip of a knife to shape small hearts.
It's easy to shape the sticky cereal mixture when the cookie cutter and your hands are well-coated with nonstick cooking spray. Respray the cookie cutter as needed, usually after every second or third use. The popularity of cereal bars and the cute shaping of this recipe make these bears a hit for holiday bake sales.
