The recipe was on a box of Hy-Vee brand of gram cereal.
To make these you will need to melt 5 T. butter over medium low heat.
Add 1/4 cup corn syrup and a 10 oz bag of miniature marshmallows minus 1 cup.
Once the marshmallows are melted add 1 t vanilla.
Then add 1 box of graham cereal, a 12 oz bag of chocolate chips, and the reserved 1 cup of marshmallows.
Add to a greased 9 x 13 pan, pack down firmly. Let cool completely before cutting into bars.
It is pretty much the same recipe. Enjoy!
