Rocky road ice cream is loaded with marshmallows and nuts, nestled in a dreamy chocolate base! It’s the perfect summertime treat.

My kids are always clamoring for ice cream, no matter the season. Lucky for them I love making it, so it’s a rare day we don’t have a batch in the freezer.

The latest batch is this fantastic rocky road ice cream. I don’t buy rocky road, but making it at home has turned it into a family favorite!

It starts with a smooth, egg-free chocolate custard and is finished off with the addition of marshmallows and peanuts. 

If you love chocolate ice cream, you’ll want to give this one a try!

What is rocky road ice cream?

There are varying stories about how rocky road ice cream was invented in the United States. 

It is derived from the rocky road candy that originated in Australia, which features milk chocolate, nuts, marshmallows, and other ingredients such as coconut.

The ice cream was reportedly invented by William Dreyer in 1929 and was given the name “rocky road” after the stock market crash to bring a smile to customers during the Great Depression.

In the early days the ice cream was hard to produce due to the addition of the mix-ins, but thanks to electric ice cream machines it’s easy to do at home!

How to make rocky road ice cream

Before you can make ice cream, place the canister of your ice cream maker in the freezer for at least overnight, or until completely frozen.

I usually put mine in the freezer the day before I want to make ice cream. If it isn’t cold enough, the ice cream won’t churn properly. 

Keep it frozen while you prepare the custard.

Gather your ingredients:

  • Heavy cream (also labeled as heavy whipping cream)
  • Cocoa powder, preferably Dutch process
  • Granulated sugar
  • Semisweet or bittersweet chocolate, broken into pieces
  • Milk (I use 2% but you can use whole if you like; I don’t recommend skim for ice cream)
  • Pure vanilla extract
  • Salt

You’ll also need mini marshmallows and peanuts, but not until later.

In a saucepan, combine cream, cocoa powder, and sugar. Bring to a gentle boil, whisking to melt sugar and combine ingredients. 

Once boiling, remove from heat and whisk in chocolate to melt completely. 

If needed or desired, transfer the mixture to another container for the refrigerator. Keep whisking while you add the milk, vanilla, and salt. The mixture should be uniform in color with only a few (if any) flecks of chocolate)

Cover the ice cream mixture and place in the refrigerator for a minimum of 2 hours to chill completely. 

You can make this in advance and churn when you’re ready. I like to make the ice cream base at night and then churn it the next day, so we have fresh ice cream ready for an afternoon snack!

When you’re ready to churn, place the frozen bowl into your ice cream machine. Give the ice cream base one final whisk and pour it into the bowl. Freeze according to manufacturer’s instructions.

In the last minutes of churning, add the mini marshmallows and nuts. I add in batches so it does not clog the machine; keep a spatula nearby in case you need to help push the ice cream back down.

You can enjoy rocky road ice cream right out of the machine as soft-serve, or transfer it to an airtight container and freeze until more solid.

What kind of ice cream maker should I use?

My favorite ice cream maker is a Cuisinart 2-quart ice cream maker. This is just the right size for most recipes, especially those with mix-ins.

Smaller ice cream machines can overflow during churning if there is too much liquid added, so if you have a 1-quart machine keep an eye on it while it churns.

This recipe is not for the ice cream makers that require ice. However, those are great for those who need a larger capacity, as they make about 4 quarts of ice cream.

You can also use an ice cream bowl for the Kitchen Aid, if you have one.

Recipe Substitutions

Marshmallows – If you like, you can swap the mini marshmallows with marshmallow cream or fluff. This will give your rocky road ice cream a lovely swirl of marshmallow throughout! 

Make sure to warm the marshmallow fluff slightly so that it is easier to spoon into the ice cream. You don’t want it hot; just a few seconds will do.

Nuts – This rocky road recipe uses peanuts, but you can swap in other nuts as well! 

Try it with sliced or slivered almonds, walnuts, or cashews. Chopped pecans would also be delicious. Make sure any nut you use isn’t too large so they mix in easily.

You can also add chocolate chips if you like, but I prefer to leave them out.
