This Rocky Road Brownies Recipe is a fudgy and gooey recipe, which is made with miniature marshmallows and semisweet chocolate chips. It’s the ultimate comfort food recipe, ready in about an hour.
Rocky Road Brownies Recipe Ingredients
- ½ cup (1 stick) unsalted butter, cut into pieces, plus more for pan
- 1 bag (12 ounces) semisweet chocolate chips
- ½ cup granulated sugar
- ½ cup packed light-brown sugar
- ½ teaspoon salt
- 2 large eggs
- ¾ cup all-purpose flour, (spooned and leveled)
- 1 cup miniature marshmallows
- ½ cup chopped nuts, such as cashews, pecans, or walnuts
How To Make Rocky Road Brownies
- Prep Oven and Melt Chocolate: Preheat your oven to 350°F (175°C). Butter an 8-inch-square baking pan and line it with parchment paper, leaving an overhang on two sides. Butter the parchment. In a heatproof bowl set over a pot of simmering water, combine the butter and 1 cup of the chocolate chips. Stir occasionally until everything is melted and smooth, about 3 to 5 minutes.
- Mix the Batter: Remove the chocolate mixture from the heat. Stir in the granulated sugar, brown sugar, and salt. Add the eggs and stir until combined, then fold in the flour until just incorporated.
- First Bake: Spread the batter evenly into the prepared pan. Bake for 30 to 35 minutes, until a toothpick inserted into the center comes out with moist, fudgy crumbs attached.
- Add Toppings and Final Bake: Remove the brownies from the oven and immediately sprinkle the remaining chocolate chips over the top, followed by the marshmallows and chopped nuts. Return the pan to the oven and bake for about 5 more minutes, until the chocolate is shiny and the marshmallows are puffed and slightly toasted.
- Cool and Slice: Let the brownies cool completely in the pan on a wire rack. Once cool, use the parchment paper overhang to lift the entire slab out of the pan. Cut into 16 squares and serve.

Recipe Tips
- How to get a gooey marshmallow top? The short, second bake at the end is the key. It perfectly melts the marshmallows and lightly toasts them without burning, creating that classic gooey rocky road texture.
- How do I know when the brownie is done before adding toppings? The toothpick test is your best friend. You want the toothpick to come out with moist, fudgy crumbs, not wet batter. If it’s clean, the brownies are slightly overbaked.
- Can I use a different type of nut? Absolutely. While the recipe suggests cashews, pecans, or walnuts, chopped almonds or peanuts would also be delicious.
- How to get clean cuts? It is essential to let the brownies cool completely before slicing. The melted marshmallow topping needs time to set. For extra-clean squares, use a large, sharp knife and wipe the blade clean between cuts.
What To Serve With Rocky Road Brownies
These decadent brownies are a treat on their own, but they are even better with:
- A tall glass of cold milk
- A scoop of vanilla bean or chocolate ice cream
- A drizzle of warm caramel sauce
How To Store Rocky Road Brownies
- Room Temperature: Store the brownies in a single layer in an airtight container at room temperature for up to 3 days. The marshmallows can become a bit sticky, so placing parchment paper between layers can help.
- Freeze: These brownies freeze well. Wrap them individually in plastic wrap and place them in a freezer-safe bag for up to 3 months. Thaw at room temperature.

FAQs
Yes, you can. For the best result, use kitchen scissors to cut the large marshmallows into smaller, quarter-sized pieces before sprinkling them on top. This will help them melt more evenly.
The second bake time is very short and specific. Leaving them in for even a minute or two too long can cause the marshmallows to burn rather than toast. Keep a close eye on them during that final 5-minute bake.
Of course. If you have a nut allergy or simply don’t prefer them, you can omit the nuts entirely for a delicious chocolate and marshmallow brownie.
