Yes, you can taste the rum in Grandma’s Rum Balls! They’re an easy, no-bake cookie that everyone will love.
Every Christmas, my grandma made old fashioned Rum Balls. And everyone LOVED them. They’re packed with chocolate, walnuts, and of course, rum!
One taste sends me right back to Christmas at Grandma’s, when rum balls were served on a platter with Snowballs and Chocolate Shortbread Squares.
Grandma’s ancestors were from Germany, so this recipe is likely German.
Here’s a look at grandma’s typewriter-written recipe:
I refined the recipe only slightly, adding clarification for ingredients and instructions. Read on for how to make them!

Choosing the rum
These old fashioned Rum Balls get get their name from the addition of ⅓ cup of rum. I used Bacardi White Rum, which is about $12 for an entire bottle. You can definitely taste the rum, so don’t purchase a super cheap variety.
Choose whatever rum you like. If you’t not a rum drinker, I recommend getting Bacardi—it’s good without being overly expensive.
Ingredients
- Semi-sweet chocolate chips make these balls extra chocolate-y. You could also use dark chocolate chips or bittersweet chocolate chips.
- You’ll need granulated sugar both for the rum ball mixture and for rolling the balls.
- White rum is best for this recipe. Avoid anything labeled spiced rum.
- Grandma’s recipe calls for walnuts. Pecans work, too! Make sure they are finely chopped.
How to make rum balls
Start by placing the vanilla wafers in the bowl of a food processor
. Process until the wafers are in fine crumbs. Alternatively, place the wafers in a large zip-top bag, seal, and crush the wafers using a rolling pin or meat mallet.
If you’re using a food processor, you can also use it to chop the walnuts into very small pieces. Otherwise, a knife and a cutting board work great for chopping the walnuts.
Next, microwave the chocolate chips in 30 second intervals until melted. Stir in between each 30 second interval so the chocolate chips melt evenly.
Stir in the sugar, rum, and corn syrup. Tip: when measuring the corn syrup, spray the tablespoon with cooking spray—the corn syrup will slide right out!
I use an oil mister
that I refill with vegetable oil. It’s way cheaper than buying cooking spray, and you know exactly what’s in it.
Then, stir in the vanilla wafer crumbs and walnuts. Refrigerate the mixture for 30 minutes.
When you’re ready to roll the rum balls, place ⅓ cup of granulated sugar in a shallow dish. Scoop the dough into 1 inch pieces, roll with your hands until round, and roll in the sugar.
I find that a cookie scoop/ice cream scoop with a release lever is the easiest way to scoop out the dough. I have this cookie scoop
, which I fill about halfway with dough to create 1 inch balls.
If the dough is too firm to scoop, let it sit at room temperature for 15 minutes, then try again. It will continue to soften as it sits.
Rolling the balls
White sugar is a very traditional topping for Rum Balls. That’s what Grandma used, so that’s what I prefer.
You could also roll them in cocoa powder, powdered sugar, very finely chopped coconut, or chocolate sprinkles.
After rolling, they are ready to serve.
I love that this is a no-bake recipe. That’s a big plus when there’s a lot of Christmas cooking/baking going on!
Rum Balls: Frequently Asked Questions
Instead of white rum, try using bourbon to create bourbon balls!
I don’t recommend using spiced rum for this recipe. It has spices added such as anise, allspice, and ginger. White rum has a very mild flavor and no spice, which is best for rum balls.
To crush vanilla wafers, place them in a large zip-top bag and seal the bag. Pound the bag with a meat mallet or rolling pin to crush the wafers. It might take a few minutes, but they will turn to crumbs eventually!
To make rum balls that are nut-free, simply omit the nuts. You do not need to change anything else about the recipe. It will yield fewer rum balls but they will still be really delicious.
The answer to this question is up to you! The recipe calls for ⅓ cup rum, and it makes 42 rum balls. Each rum ball contains approximately ⅓ of a TEASPOON of rum. I ate them as a kid, and I turned out ok, I think! 😉
You would have to eat a LOT of rum balls to feel the effects. 🙂 Each rum ball contains approximately ⅓ of a teaspoon of rum.
Storing and freezing
Storing Rum Balls depends on how you would like to eat them. They will be slightly softer at room temperature, or firmer when refrigerated.
Whether you keep them on the countertop or in the refrigerator, place them in an air-tight container before storing. The Rum Balls will keep in the refrigerator for up to 1 month or on the countertop for 1–2 weeks. They may keep longer but I haven’t been able to keep them around long enough to find out! 🙂
You can also freeze these. Place them in an air-tight container or freezer storage bag, and freeze for 1–2 months. Defrost them for 3–4 hours on the countertop at room temperature.

Terri says
Made these for our ladies cookie exchange and they turned out great. I tripled the recipe and let me tell you mixing them and rolling them out is a serious workout. I measured the dough balls for consistency so about .45-.50 ounces each makes a perfect sized ball and resulted in about 120 rum balls. I rolled them in Caster Sugar for a very nice looking finish.
Kate Shungu says
I’m so glad to hear this, thanks, Terri!
Myrna says
What if they don’t hold together when forming the balls
Kate Shungu says
Hi Myrna,
Were the chocolate chips melted completely? And were all the ingredients added as written? I’m a little bit at a loss—I’ve made these dozens of times and haven’t had that happen.
Kristina says
Can these be made ahead and frozen?
Kate Shungu says
Yes! I have some in my freezer right now. 🙂 Put them in something to protect them (like a freezer bag) and then thaw at room temperature overnight. Hope you enjoy them!
Longe says
These are seriously addicting!
Corey says
Is this a spiced rum or white rum?
Kate Shungu says
White rum!
Gartner says
Malibu balls are chilling in the fridge (no Bundy rum on hand ??). Made the mistake of trying to mix a double batch in the TM5. The mixture was a little too heavy to blend so I dropped it out onto the pastry mat and kneeded the mixture like dough. Blended quickly and was processed in half the time it normally takes me.
Nancy Anderson says
Is the sugar in this recipe powdered or granulated? Want to make these. They look delicious.
Kate Shungu says
Hi Nancy! It’s granulated sugar. I’ll update the recipe now so there’s no confusion—thanks!
Nancy A says
Thanks!
Kate Shungu says
Hi Shannon, thanks for your comment! Did you measure them after you crushed them? If so, I wonder if the brand of wafers makes a difference. Just guessing here—I’m curious as to why you needed a whole extra cup!
Fran says
Will they come out ok if I skip the corn syrup?
Kate Shungu says
Hi Fran! Unfortunately, the rum balls won’t stick together without the corn syrup. I haven’t experimented with any other sweeteners to know if you could substitute honey or agave. If you try it, let me know!
Diana says
Is the two cups of vanilla wafers before or after they are crushed?
Kate Shungu says
Hi Diana, they are measured after they are crushed.
Jeanette says
I can’t use nuts of any kind, would I have to increase the vanilla wafers for consistency? Or sub chocolate chips.
Kate Shungu says
Hi Jeannette! You can just leave out the nuts. The recipe won’t yield as many rum balls, but they will still taste amazing! I haven’t tried it, but I suspect mixing in 1 cup of mini chocolate chips would be delicious, too (don’t melt them with the other chocolate chips, just mix them in whole). You do not need to increase the vanilla wafers if you leave out the nuts. Happy baking!
Andrea says
How long can you store in an airtight container? If I send them in a military care package overseas would they still be okay to eat after 2-3 weeks?
Kate Shungu says
Hi Andrea, I’m honestly not sure! I *think* that they would still be good after 2–3 weeks. I’ve kept them as long as a week and they tasted the same and still had the same consistency. Thank you for you and your loved one’s sacrifice to serve our country. <3 Happy holidays to you!
Meghan says
If no one in my family likes walnuts, what substitute would you suggest?
Kate Shungu says
Hi Meghan, you could use pecans instead!
Meghan says
Thank you! Also, are the vanilla wafers like the round cookies or the rectangular crispy ones?
Kate Shungu says
The round ones! Nilla wafers or a similar version.
