Inspired by rocky road ice cream- rocky road brownies! This recipe takes the classic ice cream to a whole new level with fudgy brownies, almonds, and gooey marshmallows baked on top. Easy to make in one bowl in less than one hour!
Confession time- I never actually tried rocky road until about a year ago; crazy right?! Although, I knew once I tried it that I needed to develop these rocky road brownies.
The base of these brownies is my s'mores bars, which is one of my favorite recipes for summer! The gooey marshmallow layer is baked onto the brownies, then sprinkled with more almonds and even more melted chocolate.
why you'll love these rocky road brownies
- These brownies taste just like rocky road ice cream (minus the ice cream) in brownie form! Although I highly recommend serving them with a scoop of vanilla or chocolate ice cream on top while they're still warm!
- This recipe requires less than 10 ingredients and can be made in one bowl, no stand mixer is required. It's very similar to my mint brownies!
ingredient notes & substitutions
Mini marshmallows: I tested these rocky road brownies with both mini marshmallows and large marshmallows, and found that the mini ones work best.
Semi-sweet chocolate chips: You can use dark chocolate chips instead. I don't recommend using white or milk chocolate chips because they will make the brownies too sweet.
Dutch-processed cocoa powder: This recipe calls for unsweetened Dutch cocoa powder for a rich chocolate flavor. You can substitute it with regular cocoa powder if needed.
Feel free to substitute the almonds with your favorite nuts like walnuts, peanuts, or a combination. You can also top them with homemade marshmallows!
Line a metal square 8x8 baking pan with parchment paper on all four sides. Then preheat the oven to 350 F/180 C.
Step 1: Whisk the wet ingredients. In a large bowl, whisk the brown sugar, granulated sugar, eggs, egg yolk, and vanilla extract together until combined.
Step 2: Stream in the chocolate mixture. Whisking constantly, slowly stream in the melted butter and chocolate chips into the bowl. Mix until just combined.
Step 3: Fold in the dry ingredients. Use a rubber spatula to gently fold in the flour, cocoa powder, espresso powder, and salt until just combined.
Step 4: Bake! Pour the brownie batter into the prepared baking pan and sprinkle the chopped almonds over the top. Bake the brownies in the preheated oven for 33-40 minutes.
Step 5: Add the marshmallows. Pull the pan out of the oven and sprinkle the miniature marshmallows over the top of the brownies. Return to the oven and bake for 2 minutes longer (watch them carefully!) until they look puffy and lightly golden brown.
Alternatively, use a kitchen torch (my preferred way!) to lightly toast the marshmallows.
Step 6: Cool and cut. Cool the pan of brownies on a wire rack until completely cool before cutting. Drizzle them with melted chocolate and more sliced almonds if desired.
Serve warm with a scoop of ice cream. Enjoy your rocky road brownies!
expert baking tips
- Use a kitchen scale. Baking with a scale is much more accurate than cup measurements. To convert this recipe, click the "metric" button next to the ingredients title on the recipe card. If you do not have a scale, use a spoon to fluff the flour first, then spoon it into your measuring cup.
- Cut when cool. I know it's impossible to wait, but the brownies will fall apart if cut into when still warm.
- Enjoy warm. I think all brownies are better served warm! Once cut, gently warm them in the microwave and serve with ice cream if desired for the ultimate treat.
- Use a metal pan. Glass or ceramic pans retain heat differently and will need to bake at a different temperature or will need the bake time adjusted.
storage & freezing
Store leftover brownies in an airtight container at room temperature for 2-3 days.
You can freeze the baked brownies in an airtight container for up to 1 month!
Rocky Road ice cream is a chocolate-based ice cream that is packed with marshmallows pieces and almonds!
Definitely! I recommend cutting them into 4-5 smaller pieces and they should melt just like the mini ones.
Yes! Follow the instructions on the box for baking and mixing.
I have not tested this recipe with gluten-free flour, but I often hear readers have success using a 1:1 ratio like Bob's Red Mill Gluten-Free Flour!
Run a sharp knife under hot water then liberally spray or oil it (canola oil works best). In between cuts, run the knife under hot water and wipe it clean before re-oiling it. This should keep the marshmallows from sticking to the knife!
