Thats a really great tradition you've got. It's such a lovely thing to do as a family. I used 1.55oz bars. And remember to watch it when broiling. It can brown real fast. Hope you enjoy ?

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 am so sorry, I meant to correct this, they only go in the brownie mix. Hope it turned out ok and you enjoyed it!

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!

Thank you Mrs Gennrique

I appreciate your feedback on this recipe. Sometimes we can miss the glaringly obvious mistakes. Not afraid to admit I'm human and it happens more times than I'd like to admit.

I'm actually going to take out the chocolate chips divided, probably not paying attention when I was writing it up, most likely. And I would agree with you on mixing the toppings before broiling for a few minutes.

Thanks again and I'm so happy that you enjoyed it :)
