I often make a big batch of these peanut butter-flavored cereal bars on days that I don't want to heat up the kitchen. Kids especially love them, so they're great for picnics, potlucks and school bake sales. —Jane Thompson, Eureka, Illinois
In a large microwave-safe bowl, combine the sugar and corn syrup. Microwave on high for 2 minutes or until sugar is dissolved. Stir in peanut butter until blended. Add the cereal, pretzels and M&M's; stir until coated. Press into a greased 15x10x1-in. pan. Cut into bars.
