I never seem to have marshmallows around the house when I want a rice crispy treat - here is the solution from and old Grays Lake recipie book with a new twist.
Peanut Butter Rice Crispy Treats
by Linda Stoor
1 cup sugar
1 cup Karo syrup
1 cup peanut butter
7 cups Rice Crispies
chocolate chips (optional)
Bring the sugar and Karo syrup to a boil - quickly stir in the peanut butter and then the rice crispies. We like to melt a layer of chocolate chips in a fancy Demarle mold & then spread the treats over that. We cool it & it is pretty cool looking! If you don't have one of the fancy molds, just put it in a 9x13 pan & spread some melted chocolate chips over the top. So easy & good!
