I've had this treat since I was little, and I'm not sure why we called it Oh Henry Bars, because they aren't really like the candy bar (I haven't had the candy bar in ages, maybe it does have similar flavors, I don't remember). Other people call these scotcheroos, so whatever you call them, it's a fantastic way to make rice crispy treats.
1 cup sugar
1 cup light corn syrup
1 cup peanut butter
6 cups gluten free crisp rice cereal
1 1/2 cups dairy-free chocolate chips
Grease a 9X13 pan and set aside. Place corn syrup and sugar into large saucepan. Cook over medium heat, stirring frequently, until sugar dissolves and mixture begins to boil. Boil one minute. Remove from heat. Stir in peanut butter. Mix well. Add cereal. Stir until well coated. Press mixture into pan. Set aside.
Melt chocolate over a double boiler and spread evenly over the cereal mixture. Let the chocolate cool and firm up before cutting.
