Bring corn syrup and brown vegan sugar just to a rolling boil; remove from heat and stir in peanut butter until it turns into a gooey mess. Stir in cereals and chocolate chips; mix well. Wet hands; spread glop into a 9 x 13 pan and let cool. Cut into bars.
This recipe has been a family favorite for forever; I happened to ask for the recipe recently and discovered to my amazement that didn't even have to be veganized as long as you use vegan chocolate chips!
