⭐ Ingredients
For the Brownie Base
-
1 box brownie mix, family-size (18–20 oz), any brand
-
Ingredients listed on the box (usually eggs, oil, and water)
For the Rocky Road Topping
-
1 ½ cups semi-sweet chocolate chips
-
2 tablespoons butter
-
1 cup mini marshmallows
-
1 cup salted peanuts (or walnuts/pecans if preferred)
-
½ teaspoon vanilla extract (optional)
-
Pinch of salt
⭐ Instructions
1. Prepare the Brownie Base
Start by preheating your oven according to your brownie mix instructions — typically 350°F (175°C) for a metal pan or 325°F (165°C) for a glass pan.
Grease or line an 8×8 or 9×13 baking dish with parchment paper. Parchment is ideal because it makes removing the brownies in one solid slab much easier.
In a large bowl, combine your boxed brownie mix with the required wet ingredients. Mix until just combined — overmixing will make the brownies tough instead of fudgy.
Spread the batter evenly in your prepared pan and bake according to package directions. You want the brownies slightly underbaked in the center because they will firm up as they cool and the topping adds additional heat.
