There is nothing quite like a phenomenal brownie. At least, not in my humble estimation. Also, I would argue that to qualify as an extraordinarily good brownie, one must have ample chocolate frosting.

And nuts. Yes, definitely nuts. Then something to take it over the top. Would you like to know what drives these rocky road brownies to be a remarkable home run? Why it's the marshmallow layer... obviously.

Brownie Rocky Road

Our rocky road brownies are made on a cookie sheet, which is code for "invite your friends over" or "get your stretchy pants on," because this recipe makes a bunch. 

I love that I always have some leftover to share with friends. 

Here is a simple pictorial, but scroll down for a full video if you are a visual person.

Rocky Road Brownie Recipe

Six photos in a collage showing detailed steps of how to make rocky road brownies.

Top Left - Preheat your oven to 350 degrees. Blend together melted butter and cocoa until smooth. Gradually add in flour and sugar. Add in eggs and vanilla and mix until just combined. Your batter will be thick.

Top Right - Pour batter into a greased cookie sheet. You may need to use a spatula to get it flattened out to all the edges. Bake for 18-25 minutes or until a toothpick comes out mostly clean.

Middle - Remove brownies from oven and quickly cover evenly with the entire back of mini marshmallows. Return to oven for 2-3 minutes.

Bottom Left - Marshmallows should be soft and melty and kind of spread together. Do not spread with a spatula.

Bottom Right - Let brownies cool completely while you make the frosting. Once cooled, frost directly over the top of the marshmallow layer and top with chopped pecans.
