Rocky Road Brownies

If you're someone who believes that brownies should never be boring, then you're in for a treat. I’ve always had a soft spot for gooey, chocolate-packed desserts, but when I first made these Rocky Road Brownies, I knew I had hit gold. The blend of fudgy chocolate, fluffy marshmallows, and crunchy nuts is the kind of decadence that instantly satisfies any sweet tooth. And yes, they’re every bit as indulgent as they look.

This recipe has become my go-to for parties, potlucks, or even just a cozy night in. It’s one of those bakes that people talk about long after the last square has vanished. You get that rich, deep chocolate flavor, a chewy center, melty chocolate chips, and surprises of soft marshmallow and roasted nut in every bite. Whether you’re baking for a crowd or just to treat yourself, these brownies never disappoint.

Why You’ll Love This Rocky Road Brownies Recipe

These brownies strike the perfect balance between chewy and gooey, with bursts of texture thanks to toasted nuts and pillowy marshmallows. They’re as satisfying to eat as they are to look at, with a glossy top and irresistible pockets of melty chocolate. Plus, you only need basic pantry ingredients, and everything comes together in one bowl with minimal fuss.

They’re also incredibly customizable, which makes them perfect for various dietary preferences or whatever you happen to have on hand. Whether served warm with ice cream or cold from the fridge, they’re just downright addictive.

What Kind of Marshmallows Should I Use?

Mini marshmallows work best here since they melt just enough without completely disappearing into the batter. If you only have large marshmallows, just chop them into smaller pieces. I also recommend using fresh marshmallows—stale ones won’t melt properly and may ruin the texture.

Options for Substitutions

• Nuts: Traditionally, rocky road includes walnuts or almonds, but you can swap them for pecans, hazelnuts, or even peanuts. For a nut-free version, try crushed pretzels for added crunch.
• Chocolate: While semi-sweet chocolate chips are a classic choice, feel free to mix in dark, milk, or even white chocolate chips for variation.
• Marshmallows: Vegan marshmallows can be used as a substitute if you're avoiding gelatin.
• Flour: You can try using a gluten-free 1:1 baking flour to make the recipe celiac-friendly.

Step 1: Preheat and Prep

Start by preheating your oven to 350°F (175°C). Line an 8x8-inch square baking pan with parchment paper, letting the edges hang over the sides for easy lifting later. Lightly grease the parchment with butter or cooking spray.

---

Step 2: Melt Butter and Mix with Sugars

In a large microwave-safe bowl, melt the butter. Stir in both the granulated and brown sugar until fully combined and slightly cooled. This step is crucial for that shiny top layer on your brownies.

---

Step 3: Add Eggs and Vanilla

Beat in the eggs, one at a time, followed by the vanilla extract. Whisk thoroughly to create a glossy and smooth mixture. This builds the base structure of your batter.

---

Step 4: Sift in Dry Ingredients

Sift the flour, cocoa powder, salt, and baking powder directly into the bowl. Fold gently until just combined. Don’t overmix, or you might end up with cakier brownies.

---

Step 5: Fold in Chocolate Chips and Nuts

Add the chocolate chips and chopped nuts. Fold until evenly distributed. This step ensures you get a melty, crunchy surprise in every bite.

---

Step 6: Layer and Add Marshmallows

Pour half the batter into the prepared pan. Sprinkle a generous layer of mini marshmallows, then top with the remaining batter. Lightly smooth the top with a spatula. Press a few extra marshmallows and chocolate chips on top for visual appeal.

---

Step 7: Bake

Bake in the center of the oven for 30 to 35 minutes. The center should be just set, and a toothpick inserted in the middle should come out with moist crumbs (not wet batter). Don’t overbake, or you’ll lose that fudgy center.

---

Step 8: Cool and Slice

Let the brownies cool completely in the pan—at least 1 hour. Use the parchment to lift them out and slice into squares. Clean your knife between cuts for neater edges.

How Long to Prepare the Rocky Road Brownies

Preparation Time: The prep takes about 15–20 minutes. That includes melting the butter, mixing the ingredients, and layering the batter with marshmallows and nuts. It’s straightforward and quick, especially if you’ve pre-measured your ingredients.

Baking Time: These brownies typically bake for 30 to 35 minutes. Let them cool for at least 1 hour before slicing to let them set properly. From start to finish (including cooling), you’re looking at just under 2 hours.

Tips for Perfect Rocky Road Brownies

• Use room temperature eggs for better emulsification.
• Don’t overmix the batter once you add flour—it can lead to cakey brownies.
• Sprinkle extra marshmallows and chocolate chips on top before baking for that irresistible rocky road look.
• Use a metal pan instead of glass to avoid overbaking.
• Let them cool completely before slicing for clean, sharp edges.

Watch Out for These Mistakes While Cooking

• Overbaking: It’s easy to bake too long. Pull them out when the center still has moist crumbs.
• Using stale marshmallows: They don’t melt properly and can ruin the gooey texture.
• Cutting too soon: The brownies need time to cool and firm up.
• Using too much flour: Always spoon and level your flour. Too much can make them dense.
• Under-mixing the sugar and butter: This can lead to a gritty texture and a dull top.
