Ingredients and Substitutions
- Unsalted Butter - Melted butter makes these brownies soft and dense.
- Granulated Sugar - Light brown sugar works well if you do not have granulated sugar.
- Dry Ingredients - All-purpose flour, cocoa powder, and salt are needed. Cocoa powder is the prime source of chocolate in the brownie batter.
- Toppings - These rocky road brownies are topped with semi-sweet chocolate chips, mini marshmallows, and chopped walnuts. Marshmallow fluff is a great substitute if you do not have mini marshmallows on hand. One jar is more than enough. Regarding the nuts, you can use chopped almonds or cashews instead of walnuts.
Preheat the oven to 350° F. Grease and line an 8X8-inch baking pan with parchment, and set aside.
Whisk together the slightly cooled melted butter and granulated sugar in a medium-sized bowl. Whisk well for 1-2 minutes. Add the eggs and vanilla extract, and whisk for an additional 2-3 minutes until light in color.
Whisk together the flour, cocoa powder, and salt in a small bowl. Carefully fold the dry ingredients into the egg mixture until well incorporated. Fold in ⅓ cup of the semi-sweet chocolate chips.
Pour the batter into the prepared pan, and spread it out evenly. Bake for approximately 20 minutes or until set.
Immediately after pulling out the baked brownies, sprinkle the top surface with the mini marshmallows, chopped walnuts, and the remaining ⅓ cup of semi-sweet chocolate chips. Bake for an additional 2 minutes or until the marshmallows have softened and the chocolate chips are gooey.
Allow the brownies to cool for at least 1 hour before serving. Serve at room temperature or warm.
- Sift your dry ingredients. - Cocoa powder tends to clump up. Sift all of the dry ingredients (flour, cocoa powder, and salt) together before adding them to the egg mixture.
- Grease and line the baking pan. - Because of the multitude of toppings on these rocky road brownies, they are sticky and will stick to the pan. For easier and cleaner slices, line the pan with parchment in addition to greasing with baking spray. Simply pull the parchment up on both sides of the brownies and transfer it to a cutting board.
- Instead of the chocolate chips on top, use a chocolate ganache. - Make a small batch of ganache and drizzle it over the marshmallow-nut layer.

Do you use Sweetened Coca Powder or Unsweetened?
Melissa, I apologize, I missed this comment. This recipe uses unsweetened cocoa powder.
Delicious! I added some instant coffee crystals with the vanilla extract to punch up the chocolate. I used a Dutch cocoa, beautiful and dark. I made a small batch by halving the recipe and baked it in a bread pan. Otherwise I would be tempted to run amok with all those wonderful brownies in the house.
Eli, I love the addition of the instant coffee crystals. I am so happy to hear that you enjoyed this recipe. Thank you for the positive review!
