This Rocky Road Brownies recipe is FANTASTIC! Do not be tempted to use a brownie mix —these really are SO much better! The base is thick and fudgy, topped with ooey gooey marshmallow and a perfect chocolate fudge frosting. YUM! I left the nuts our for my no- nut-loving family (crazy boys) and the brownies were still great, but personally I LOVE the nuts in this recipe and would suggest using them. This recipe makes a lot so it is the perfect treat to share at a gathering. This recipe comes from my sweet neighbor and friend Helene P, who is an excellent cook. They are a family favorite of theirs and I can see why! They can easily be made a day ahead of time and will still be wonderful! Trust me when I say—these are awesome!!

I just wanted to come back and do an update since I made these. I baked mine in a 9×13 pan for the listed time and they came out perfect. The brownie part of these are to die for! Really, really good. The whole combination is fantastic.

HI Kerri,
That is not a silly question! I iwll tell you that the pan I use for this recipe is my Pampered Chef Stoneware rectangular bar pan. It is perfect. I have never doubled it because this recipe already makes a lot! If you are baking for a crowd and you double it then, yes use a 1/2 sheet pan. That should work great!

Sonia,
Yes you do melt the butter and chocolate for the frosting. I will note that in the recipe! Thank you for bringing that to my attention!

This is probably a silly question… recipe calls for 15″ x 12″ pan, and a 1″ deep cookie sheet to double the recipe. I haven’t had much luck finding a 15″ x 12″ pan. Is your 15 X 12 pan a cake pan? When say a 1″ deep cookie sheet, do you mind elaborating on the dimension of the cookie sheet? Are you perhaps referring to a 1/2 sheet pan?
Thanks!

I can’t wait to try these! I was, literally, searching for this recipe just a few days ago. It’s been years since I had these brownies and couldn’t find the recipe. One of my favorite combinations. I think I might add peanuts.
