Melt down the butter and 5 cups of marshmallows stirring pretty much constantly, until completely smooth.
Remove from heat and mix in the cereal.
Mix in the chocolate chips and the extra 1 cup of marshmallows.
Press the mixture into the pan.
Press Hershey's squares into the bars.
Cut into squares.
VoilĂ !
Notes
* You could also use regular sized chocolate chips. They melt down when you mix them in so just give them a little more time to melt down if you use regular chocolate chips.
