What is in rocky road?

Rocky road is traditionally made up of marshmallows, chocolate, and peanuts (or some other crunchy nut). You’ve probably had this flavor in an ice cream cone or homemade fudge, and I promise you, it’s just as good in these brownies. The marshmallows work to cut some of the richness of the brownies and the peanuts add a much needed crunch.

Ingredients for Rocky Road Brownies

These are some thiccc brownies, so don’t say I didn’t warn you. The brownie base alone is more than enough, but add in the classic rocky road flavor on top and you’re in chocolatey marshmallow heaven. Luckily, they actually don’t require any crazy ingredients! You’ll need:

  • Butter
  • Brown Sugar
  • Eggs
  • Cocoa Power
  • Vanilla Extract
  • Flour
  • Mini Marshmallows
  • Chocolate Chips
  • Peanuts

You probably already have most of these ingredients on hand, and they’re made in one bowl AKA easy cleanup!

Fudgy vs Cakey Brownies?

A question that divides us all. And the great news is that you you don’t have to choose with these brownies, which are both fudgy and cakey.

Fudgy AND cakey?! But how, you ask. With a lot of testing, and many brownies consumed (we’re not complaining), we arrived at this perfect brownie that will please everyone. The eggs and whole wheat flour give the brownies that cakey brownie structure, while the high cocoa and butter content keep them fudgy and moist.

So like, best of both worlds.

How to toast marshmallows in an oven?

To get a good bake on your brownies without totally torching your marshmallows, top the brownies with the marshmallows in towards the end of the bake time. Take the brownies out when they have about 10 minutes left on the timer, sprinkle the topping on top and there you have it! If you want some burnt ones (totally personal preference) we’d recommend using the broiler and keeping your eye on them. If you’re looking for a nice even golden brown, you can just bake them at 350 ° F for about 10 minutes or until they puff up and start to brown.

The high sugar content of marshmallows means they can go up in flames pretty quickly, so keep an eye on them and make sure your rack isn’t too close to the top of your oven.

  • Prep Time: 15 minutes
  • Cook Time: 50 minutes
  • Total Time: 1 hour and 5 minutes
  • Yield: 9 huge brownies 1x
  • Category: dessert
  • Method: oven
  • Cuisine: american


  • 1 1/4 cups salted butter
  • 2 1/2 cups light brown sugar
  • 4 large eggs, room temperature
  • 1 1/2 cups cocoa powder
  • 3/4 teaspoon salt
  • 2 teaspoons vanilla extract
  • 2/3 cup Bob’s Red Mill Whole Wheat Flour
  • 2 cups mini marshmallows
  • 2 cups semisweet chocolate chips
  • 1 1/2 cups peanuts, roughly chopped


  1. Preheat oven to 350°F. Grease and line a 9″x9″ pan with parchment paper and set aside.
  2. In a large microwave-safe bowl, combine butter and sugar. Microwave for 30 seconds, then remove and stir with a whisk. Repeat process 2 more times. Though granules of sugar will remain, the goal is to get the mixture to a glossy finish.
  3. Allow mixture to cool slightly, then add in eggs one at a time, whisking in between each addition. Whisk until the mixture lightens in color slightly.
  4. Add in cocoa powder, salt, and vanilla extract. Fold in flour until just combined.
  5. Pour mixture into prepared baking pan and bake for roughly 45 minutes.Stick a knife inside the center. Once it comes out relatively clean, take the brownies out of the oven. Sprinkle the tops with the marshmallows, chocolate chips and chopped peanuts. Turn your oven to a broil to get the marshmallows to crisp up. Place the brownies back in the oven and cook for another 5 + minutes, until the marshmallows are toasted. Keep a close eye on the marshmallows, rotating the pan to ensure even toasting.
  6. Take the brownies out of the oven and allow to cool before slicing. Enjoy!

Can you use AP flour instead of whole wheat and, if so, would I need to change the quantity? The brownies look delicious.

Hey Pam! You definitely can. You can just swap cup for cup and it should do the trick 🙂
Thank you for your kind words. Hope these turn out well for you.


These look amazing! I may try them. I see you said ok to use AP flour. I do have a white w w flour too. But, will it be ok to use unsalted butter? I never use salted butter in any of my baked goods. I know I need some salt for flavor, so I could add maybe 1/4 tsp. of salt. In a lot of recipes I use, I tend to cut back on the salt. I found if I followed the recipe to the T, it was too much salt. Also big difference between Diamond Crystal and Morton Kosher salt. I use Diamond Crystal:)

Yes you can definitely use AP! And absolutely! Just reduce the salt by 1/4 tsp. Good luck 🙂


Hi! Should we use Natural or Dutched Cocoa Powder in this recipe? Does it matter? Do you prefer one over the other? Thanks!

We love Rodelle’s cocoa powder which is a dutch processed cocoa!


Hi there! Other than whole wheat flour and AP flour, can I use other flour?

Sofi | Broma Bakery

What other kinds of flour do you have on hand? It depends!


Hello! Question, how do you bake these so that the marshmallows don’t become so tough and chewy? I loved the brownie base, but the marshmallow topping was really tough and chewy. It almost felt like I was gnawing on a piece of taffy (not quite, but it was the best way I could think to describe it). I had the brownies under the broiler until the marshmallows were golden brown. Is there a way to make the marshmallows not as chewy?

Hi Natalie! Ugh that is definitely not what you want! You could try broiling them for less time or using a blow torch instead of the broiler!
