Your recipe is confusing. It says to divide chocolate chips, but then says nothing about putting them on top of brownie with Hersey’s and marshmallows. It just says to add the Hersey bars chopped to brownie mix. I hope I didn’t forget all of the chips in the melted butter. I hope they trun out all right!!

I made this for my husband as s’mores is his favorite. It was … Amazing. Like AMAZING!
Some notes and tips if you are lucky enough to try this: the recipe says the chocolate chips are “divided” and I don’t know why. I just melted the 2 cups all at once with the butter. I couldn’t find in the recipe where the other chocolate chips would be needed.
The topping says to add graham cracker last but I would add marshmallow last-or at least mix them up. The graham crackers burned under the broiler and barely toasted the marshmallow.

Otherwise it was delicious!
