Mix together syrup and peanut butter and melt in a pan. When mixture is smooth, add cereal, and stir to coat. You may also wish to embellish the recipe by adding a handful of carob or chocolate chips or chopped peanuts.
Press mixture into a lightly greased oblong pan, and let it cool. (You may need to refrigerate in order for it to harden.) When cool, cut into squares, and enjoy.
