I have made these four times now , and I think I’ve decided what I like best. Because there are seven kids, you have to double it, which gives you a 9×13 pan. We like them a little denser with coarsely crushed Oreos. The best so far is a bag and a half of marshmallows (approx. 675 g) with a half cup of butter and two trays of Oreos (each tray had three rows of 10 cookies each, so a total 60 cookies). For my taste, two bags of marshmallows (approx. 900 g) is a little too much. The bars are much too soft and chewy. No matter what, the kids always love them!
Actual yield: Doubled yields a 9×13 pan.
Verdict: The kids still love them!
