What is Rocky Road?

One of several stories is that Rocky Road was originated as a chocolate ice cream with nuts and marshmallows in 1929. The Company chose the name to give people something to smile about in the midst of the Great Depression. It was said to mimic the road that travelers took to reach the goldfields.

Can I make Rocky Road Brownies from a box mix?

Yes! You absolutely can use a boxed brownie mix, baked according to packaged instructions. Finish off with topping and drizzle.

How to apply the chocolate drizzle.

I used a piping bag with the tip cut off and then squeezed the drizzle over the brownies vertically and horizontally. You could also use a reclosable plastic bag with the corner snipped off or dip a fork into the chocolate drizzle and whip it horizontally and vertically across the top of the brownies.

How do you cut Rocky Road Brownies?

Brownies are easiest to cut when completely cooled. We recommend running a sharp knife through hot water and then wiping it dry. Make slices. Repeat running the knife through the hot water, drying it off, and making your cut.

Tips to Make the Best Rocky Road Brownies

1. Almonds, peanuts, walnuts, or pecans can be used as nuts. Lightly roasting them will add depth of flavor.

2. If in a rush use a boxed brownie mix, baked according to packaged instructions. Finish off with topping and drizzle.

3. Use your favorite chocolate chips for this recipe. I used a mixture of dark chocolate chips and semi-sweet chocolate chips when I made our Rocky Road Brownie Recipe, but milk chocolate chips or gluten-free chips, etc will also work.

Storing Leftover Brownies

If you have leftovers, you can keep them in an airtight container at room temperature for a couple of days. I’ve never frozen these brownies. It never lasted that long!
