Coated in a deliciously sweet and buttery brown sugar syrup, these walnuts in syrup are just waiting to top your next old-fashioned ice cream sundae.
If you’ve ever had an old-fashioned ice cream sundae, chances are you’ve experienced these decadent walnuts in brown sugar syrup. One of our local spots still serves a decadent nut sundae that includes a big scoop of old-fashioned vanilla ice cream topped with a generous helping of walnuts in syrup. It is absolutely delicious. My mother was over the moon when a friend gave her this recipe because they’ve always been her favorite part of getting ice cream.
So, what do you need to make my walnuts in syrup recipe? Chopped walnuts, of course, brown sugar, light corn syrup, milk, butter, and vanilla. They really couldn’t be easier to make either. All you’re going to do is bring the syrup to a boil, remove it from the heat, and then stir in the vanilla and walnuts. That’s all there is to it! They’ll be ready for your homemade ice cream sundae in a flash, which will make everyone happy.
Also known as wet walnuts, walnut syrup, or simply walnut topping, they are easy to make and keep in your fridge all summer long. Simple, old-fashioned treats are the call for the day!
- Chopped walnuts (or chopped pecans)
- Brown sugar (dark or light brown sugar works)
- Light corn syrup
- Milk (whatever milk you have on hand)
- Salted or unsalted butter
- Vanilla extract
How to Make Walnuts in Syrup
Place brown sugar, syrup, butter, and milk into a large saucepot over medium heat.
Bring just to a boil while stirring constantly.
Allow to boil for five minutes, still stirring, then remove from heat.
Stir in vanilla and walnuts and then allow them to cool.
Once cooled, transfer to a mason jar or the container of your choice and store them in the fridge.
They will be good for several weeks to a few months when stored properly in the fridge.
Walnuts in syrup are amazing when served on top of all sorts of treats!
Try them on a cake, cheesecake, yogurt, or whatever else you can come up with.
But make sure you have them on a dish of your favorite vanilla ice cream! Enjoy!
As mentioned, when stored in an airtight container in the fridge, your walnuts will last for a month or two (funny how mine seem to disappear so much sooner though…).
- For extra flavor, toast the walnuts for a few minutes in the oven or air fryer before adding them to the syrup.
- Another way to make them extra tasty is to include 1/2 teaspoon of your favorite dried spice, whether that’s pumpkin pie spice, apple pie spice, ground ginger, or ground cinnamon.
- For a kick, add a pinch of cayenne pepper.
- Adapt this recipe and use any nut you like, including chopped pecans, almonds, hazelnuts, or even a mixed nut syrup. How delicious does that sound?
What’s the difference between walnuts in syrup and pecan pralines?
The main difference between walnuts in syrup and pecan pralines is that the walnuts are always served in syrup. Pralines are typically served as individual pieces.
What can you use besides corn syrup?
Walnut syrup is often made with maple syrup, but a rarer option is brown rice syrup.
Besides ice cream sundaes, how else can you serve walnuts in syrup?
Here are some other serving suggestions:
- Enjoy them with a slice of homemade pound cake, vanilla cake, or cheesecake.
- Serve them over yogurt, pancakes, waffles, or oatmeal for breakfast.
- Enjoy them with a decadent chocolate brownie in a mug.
By the way, take your ice cream sundae to the next level and swap vanilla ice cream for chocolate ice cream, and add some hot fudge sauce on top.

OH i have hunted for this recipe for years. We used to get a “Maple Walnut” topping on sundaes at Baskin Robbins, and it was so good. I tried putting walnuts in maple syrup and it is good, but just not quite right. I will make this, and then I’m thinking I might try maple syrup in place of the corn syrup…how bad could it be? Thanks much!
The ingredient list reminds me of pecan pralines, except milk instead of cream. Will definitely be making this soon, for my ice cream. Tell your mom thanks for sharing!
10/10 on the scale of crunchy-nutty-sweet chewy syrupiness!
I could bathe in this, but it’s gonna get eaten over ice cream. Thank you for another delicious recipe!
Just finished making this. I had to take a bite before it could cool off. Delicious. Thanks for the recipe. Nut sundaes are one of my favorites.
Years ago (and I mean years ago LOL!) for my first job, I worked at our local Dairy Queen. We served Pecan Sundaes and I always wondered how they made the pecan topping! The Pecan Sundaes were one of our best sellers when we had them. The lady who was the night manager always made up the toppings for the sundaes and banana splits, so I never knew just how it was done. NOW I know! Thank you so much for sharing this recipe.

Oh wow!! I have never seen this recipe! These are my favorites on ice cream. I can not wait to try this! Thank you!
I’m so glad, Pam! You’re going to love it! (and my Mama said to tell you that they are way cheaper to make than they are to buy) 😉
Looks great, Christy! My version is much quicker and easier: I just cover walnuts in any old cheap pancake syrup. The ones with a higher sugar content are best, I usually use Aldi’s. I’m sure yours taste better, but if you’re in a big hurry…
I do the same way you do. Tastes like Smuckers walnuts in syrup.
I’m all about a shortcut when needed! Thank you for the tip!
Never heard of this & had to try it……Fabulous!! So good! However mine did curdle. What did I do wrong Christy??
I’ve never heard of this before, but I bet my butter-pecan-loving-husband would go for this! Putting it on the menu…
oh goodness, now you’re gonna make me make pecans in syrup. I love me a good butter pecan ice cream!
