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.

Club Size Beverages from Sam's Club

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.

Pouring Coca-Cola into Fudge

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?!)

Bring Coca-Cola Fudge mixture to a boil

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.

Coca-Cola Fudge with 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.
  • 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.

Ingredients
 

  • 6 Tablespoons butter
  • 1 ½ cups granulated sugar

  • ½ cup Coca-Cola or ½ Coca-Cola Mini Can
  • 1 cup semi-sweet chocolate chips
  • ½ 7 ounce jar marshmallow cream
  • ½ cup and 2 Tablespoons chopped walnuts divided

Instructions

  • Prepare an 8 x 8 inch pan with parchment paper and a thin layer of non-stick spray. Set aside.
  • Melt butter over medium heat in a large saucepan.
  • Once the butter has melted, add sugar, evaporated milk, and Coca-Cola. Bring mixture to a full boil, stirring constantly.
  • When it has reached a full boil, cook for 5 minutes while it boils, stirring constantly*. The mixture should thicken slightly. If it does not, stir and boil for another 1-2 minutes. 
  • Remove pot from heat and add chocolate chips and marshmallow cream. Mix well until the texture is smooth.
  • Stir in ½ cup walnuts.
  • Pour fudge mixture into pan and sprinkle with remaining walnuts.

Notes

*A candy thermometer is the absolute 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 a candy thermometer, use the 5-minute boil method above.
Store your coke fudge in an airtight container in the fridge. Enjoy chilled or at room temperature.
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.

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.

  1. Did NOT set up. I understood the directions and followed them precisely: bring to FULL boil, stir 5 min., etc.

  2. 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.

  3. 😒 Mine didn’t set either. I am getting ready to “re-boil” to see if thar works…stay tuned…

    1. 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!

  4. 5 minutes is not enough time. You have to continue cooking until it comes to a soft ball stage 240 degrees.

  5. I am trying to see if I can adapt this recipe to make white chocolate Mountain Dew fudge for my brother. I like your recipe because I always use marshmallow creme in my fudge, but I saw some other recipes said to reduce the soda down first. You are going to be boiling it anyway, so it seems like maybe the order doesn’t matter. I am always the person who gets super frustrated when people leave comments saying they TOTALLY altered the recipe, so I totally apologize, but if you have any ideas for me, I’d appreciate it!

    1. Oh I love this idea! To be honest I am not sure how Mountain Dew would work with the recipe. If you do decide to give it a try please let me know how it comes out!

  6. Boiled 12 minutes and it never thickened. Letting it cool now.
    Maybe it will magically set up.

  7. My mother made this fudge but without Coke for years when I was a child and her mother before her. I have her recipe but not her patience.

  8. You do not have to use the coke. I do however love coca cola myself (non paid) but would recommend drinking at least full 12 Oz can while making the fudge! 🥰 Maybe more even. Make fudge per recipe above with no coke. Go by recipe on Marshmallow cream carton🤣, yes, it’s on there or go by this one except boil about 7 minutes until soft boil stage. remove from heat, immediately aff chocolate or peanut butter chips. when chips are melted add marshmallow creme. Add 1 top vanilla. lastly add nuts if desired. spread on wax paper and refrigerate if desired. Delicious!! THEN ENJOY ANOTHER 12 OZ COCA COLA AND LEAVE THE MINATURE ONES FOR THE LIGHT WEIGHTS! COST MORE MONEY PER OUNCE FOR MINIS ALSO!!😇😇😇😇
