Key Ingredients for Best Homemade Rocky Road Brownies

See recipe card below for full list of measurements, ingredients, and instructions.

Semi-Sweet Chocolate Chips

These give the brownies a luscious, melty chocolate base and add gooey richness to every bite. For best results, melt part of the chips into the batter for fudginess and reserve some for topping. You can use dark chocolate chips for a deeper flavor, but milk chocolate may make the brownies extra sweet.

Mini Marshmallows

Classic to the rocky road flavor, mini marshmallows create those signature gooey, toasty pockets on top. Sprinkle them on during the last few minutes of baking so they melt just enough without burning. Large marshmallows can work if cut into smaller pieces, but avoid marshmallow fluff-it won't hold its shape.

Chopped Walnuts or Pecans

Toasted walnuts add that irresistible crunch and a bit of savory balance to the rich chocolate. Pecans are a delicious alternative if you prefer their slightly sweeter, buttery taste. For a nut-free version, swap out for toasted sunflower seeds or leave them off altogether.

Unsweetened Cocoa Powder

A few spoonfuls of cocoa powder make your brownies extra chocolaty and give them a deep chocolate flavor. Use natural or Dutch-process-both work here. If you swap in Dutch-process, the finished brownies may be darker and more intense.

Real Butter

Butter adds richness, moisture, and a tender crumb to the brownie base. Use unsalted butter to control the salt level, and make sure it's completely melted before using. Margarine or vegan butter can work in a pinch but may change the flavor slightly.

Instructions for Best Homemade Rocky Road Brownies

See recipe card below for full list of measurements, ingredients, and instructions.

Prep Your Pan and Oven

Preheat your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving a bit of overhang for easy lifting. Lightly grease the parchment for extra insurance against sticking.

Melt Chocolate and Butter

In a microwave-safe bowl, combine butter and ½ cup chocolate chips. Microwave in 20-second bursts, stirring between each, until melted and smooth. Let it cool slightly so you don't scramble the eggs.

Whisk Together Wet Ingredients

In a large bowl, whisk the melted chocolate mixture with sugar until it looks glossy. Crack in the eggs, one at a time, whisking well after each. Stir in the vanilla for added depth.

Add Dry Ingredients

Sift in flour, cocoa powder, salt, and baking powder. Gently fold the batter with a spatula just until combined-don't overmix or your brownies will be cakey instead of fudgy!

Fold in Toppings

Gently fold in half of the remaining chocolate chips and half of the nuts. Pour the batter into your prepared pan and smooth the top.

Bake

Bake for 22-25 minutes, until the center is just set and a toothpick comes out with a few moist crumbs. Pull the pan out of the oven.

Add Marshmallows and Finish Baking

Quickly scatter the mini marshmallows, remaining chocolate chips, and remaining nuts evenly over the top. Return to oven for 5-7 more minutes, until the marshmallows are puffed and lightly golden.

Cool, Slice, and Serve

Let the brownies cool completely in the pan for cleaner slices. Use the parchment to lift them out and cut into squares. Enjoy the gooey, crunchy goodness!

Recipe Variations

Peanut Butter Rocky Road

Love peanut butter? Swirl ⅓ cup creamy peanut butter into the batter before baking for a rich, nutty twist. Or sprinkle chopped peanut butter cups on top along with the marshmallows!

Nut-Free Version

Skip the nuts and replace them with extra chocolate chips or even pretzel pieces for salty crunch. This is great for allergy-friendly parties or school lunches.

Vegan Rocky Road Brownies

Substitute melted coconut oil or vegan butter for the butter, flax eggs for eggs, and use dairy-free chocolate chips and vegan marshmallows for a completely plant-based treat.

Gluten-Free Option

Swap the all-purpose flour for a gluten-free 1:1 baking blend-no other changes needed! Your brownies will still be rich and chewy.

Extra-Chocolatey Variation

Stir in dark chocolate chunks or use a mix of semi-sweet and bittersweet chips for a deeper chocolate flavor. You can even add a dusting of cocoa on top before serving.

Serving Suggestions

Serve your Rocky Road Brownies with a cold glass of milk, a scoop of vanilla ice cream, or fresh berries for contrast. For a party platter, garnish with extra toasted nuts and a drizzle of chocolate sauce for extra wow factor!

Storage and Reheating

Store leftover brownies in an airtight container at room temperature for up to 3 days. For longer freshness, keep them in the fridge for up to a week. To reheat, warm individual brownies in the microwave for 10-15 seconds-just enough to melt the chocolate and soften the marshmallows. For freezing, wrap cut brownies tightly in plastic wrap and store in a freezer-safe container for up to 2 months. Thaw at room temp before enjoying.

Frequently Asked Questions About Best Homemade Rocky Road Brownies (FAQ)

Q: Can I use a boxed brownie mix for this recipe?

A: Yes, you can use your favorite boxed mix as the base and add the rocky road toppings for a time-saving shortcut!

Q: What kind of nuts work best in rocky road brownies?

A: Walnuts and pecans are classic, but almonds or hazelnuts are also great. If nut allergies are a concern, simply leave them out or add crunchy seeds instead.

Q: Why do my brownies turn out cakey instead of fudgy?

A: For fudgy brownies, avoid overmixing, measure your flour carefully, and bake just until set. Overbaking or extra flour leads to a cake-like texture.
