I love this time of year! The holiday season means spending time with family and, of course, lots and lots of great holiday eats.
Between Thanksgiving, Christmas, and New Year’s Eve we have a lot of occasions to celebrate coming up, so I will be making lots of yummy holiday treats to share with family.
Homemade fudge has always been one of my favorites, but this year I wanted to try a homemade fudge recipe with a new and exciting twist.
My husband and I love Coca-Cola® and Diet Coke®. In fact, I am sipping on a Diet Coke® as I write this post. So, I thought, what would be better than a fudge made with my favorite soda — Coca-Cola®!?

And I couldn’t be happier with how the fudge came out. This tasty Coca-Cola® fudge is basically like a sweet little slice of heaven, like the double fudge Coca-Cola cake from Cracker Barrel. I can’t wait to share it with my family and friends this holiday season.
I have found that Coca-Cola® Mini Cans, available at Sam’s Club, are the perfect size for making Coca-Cola® Fudge.
Coca-Cola® Mini Cans and Sprite® Mini Cans are also absolutely adorable, and the perfect size for when I am craving a soda.
On my last trip to Sam’s Club I picked up Coca-Cola® Mini Cans along with a variety of other great beverages to serve my guests this holiday season.

To give my guests the greatest variety of beverages, I like to stock up on Coca-Cola®, Sprite®, Gold Peak® Sweet Tea, Dasani®, and Diet Coke® at Sam’s Club. By shopping at Sam’s Club I get a great value on beverages for holiday entertaining.
Plus, Sam’s Club offers Club Pickup which is perfect for busy mamas like me. After ordering online, Sam’s Club has everything ready for me to pick up as soon as I arrive. I will definitely be taking advantage of this time-saving service throughout the holiday season.

If you love sweet treats, you are going to love this Coca-Cola® Fudge.
Begin by gathering your ingredients.
For this fudge recipe you will need:
- Coca-Cola
- marshmallow creme
- granulated sugar
- evaporated milk – make sure that you do not grab a can of sweetened condensed milk by mistake. They are not the same thing and only evaporated milk will work for this recipe
- semi-sweet chocolate chips
- butter – salted or unsalted butter work for this recipe
- walnuts – Not a fan of nuts? Feel free to leave them out.
How to Make Coca-Cola® Fudge
This section shows you how to make the recipe with step-by-step photos and instructions. For the full printable recipe, see the recipe card below.
Grab an 8 x 8 inch baking pan and line it with parchment paper and a light coating of non-stick spray.
Next, melt butter in a large pot over medium heat. Once the butter has melted, add the sugar, evaporated milk, and Coca-Cola®. Stir continuously until it comes to a full boil. This will take some time, so you might want to do yourself a favor and have an extra Coca-Cola® or Diet Coke® handy so that you can enjoy a Coke while you stir.

Once the mixture comes to a full boil you will need to cook it while it boils for 5 minutes. So, set a timer for 5 minutes and continue stirring constantly. (Are you enjoying that arm workout yet?!)

After 5 minutes, remove the pot from heat and add chocolate chips and marshmallow creme, stirring until the chocolate has melted and the texture is uniform and smooth. Stir in the walnuts.
Pour the mixture into an 8 x 8 inch pan and sprinkle with remaining walnuts.

Place fudge in the refrigerator for 2 hours or until set. Once chilled, pull the ends of the parchment paper to lift the fudge out of the pan and onto a cutting board. Slice into bite-sized pieces and enjoy!

Recipe Tips
- Get all of your ingredients measured out and ready to go before you start making your fudge. Because once you begin you will be glued to the stovetop and stirring constantly.
- A candy thermometer is the best way to know when your fudge is ready. If you have one, use it to make sure the fudge reaches between 234 and 240°F before removing it from the burner. If you don’t have one, use the 5-minute boil method listed in the recipe.
- If you want to make a double batch and use an entire jar of marshmallow cream and an entire Coca-Cola mini can (or 1 cup of soda), you can do so using two 8-inch pans. However, I would recommend that you cook the two batches separately.

Note: Original recipe updated on December 21, 2021 to be halved and made in an 8-inch square pan
Some readers were having trouble getting their fudge to set using the original recipe (in a 9×13 inch pan) so we retested the recipe and did some troubleshooting. We found that it was easier to get the fudge to set up properly when the recipe was halved, likely because the amount of time needed to boil and stir the liquid works better when there is less liquid and it can get hotter in those 5 minutes.
However, if you want to make twice as much fudge and use the entire jar of marshmallow cream and an entire Coca-Cola mini can (or 1 cup of soda), you can use two 8-inch pans and cook the two batches separately to ensure that your fudge sets.
Why didn’t my fudge set up and become firm? I followed the recipe exactly, it’s been in the fridge for 10 hours. I went to cut into it to try a piece and it’s a gooey consistency. Actually need to spoon it out of the baking dish. So disappointed, I hope someone can help me with where I went wrong.
Oh no! I am so sorry to hear that your fudge didn’t set 🙁
In the past I have had trouble getting fudge to set when I didn’t boil it long enough or at a high enough temperate. The fudge really has to come to a good, strong, rolling boil — boiling so well that even as you stir it, it is still boiling strong. Then continue to boil it, while stirring, for 5 minutes.
I hope you are able to give it another go — it really is a delicious fudge!
This does not set up. a bit waste of time and money.
If you use a wooden spoon to stir with, sometimes, when making puddings and/or candy it will not set up.
Well I just put a pan in the fridge.
I am definitely worried about it because it seems runny. I definitely did a rolling boil for 5 min with a little over and it doesn’t look like the consistanty of the many many pans of fudge I have made.
I had the same issue with it not setting up, and that was after reading the other notes. I made sure it was at a full rolling boil before I started the timer. Very disappointing.
Mine came out well 🙂 Thanks for receipe!
After reading from those that their fudge didn’t set, I was wondering if the weather has anything to do with how well the fudge sets. I have heard that weather does affect some candies.
Did NOT set up. I understood the directions and followed them precisely: bring to FULL boil, stir 5 min., etc.
I made this fudge and went off the exact recipe except I didn’t have marshmallow creme so I made my own. The fudge didn’t set at first and I was rly disappointed and so I looked up ways to make it harden. I tried to reboil mine for much longer this time and it worked. The consistency was wayyy thicker and it hardened on the spatula I used to stir it while it was boiling. So if yours didn’t set, try boiling it again until it is thick.
😒 Mine didn’t set either. I am getting ready to “re-boil” to see if thar works…stay tuned…
Okay, I went wrong. What appeared to be a mini Koch was actually 12 oz and not 8 oz. Getting ready to tackle take three…. I love fudge and Diet Coke too much to quit!
