Root Beer Float Fudge

Root beer float meets root beer candy in this fudge recipe! With white chocolate and marshmallow cream, Root Beer Float Fudge is a sweet treat you won’t be able to resist.

When I was pregnant with my first child I had an addiction to root beer floats. At least once a day, I poured myself a big glass of cold root beer and topped it with a (more than generous) scoop of vanilla ice cream.

I was also addicted to gyros and french fries, but those I couldn’t make at home every night! After that pregnancy I stopped craving root beer floats quite so often but I still love them, especially on a hot day.

Root Beer Concentrate

When you put root beer concentrate into a creamy white chocolate fudge, you get a root beer candy that tastes identical to a root beer float.

The layer of vanilla fudge on top of the fudge flavored with root beer does an amazing job mimicking the “float.”

I can’t even begin to describe how delicious these taste but, since you’re hear to read about this recipe, I suppose I should at least try.

Okay, so you know the crunchy part of a root beer float? It’s when the root beer sticks to the ice cream and forms crunchy little bits of root beer flavored ice crystals.

If you eat this fudge cold, it tastes like that.

In a sea of chocolate, vanilla and peanut butter fudge recipes, this Root Beer take stands out from the crowd. The flavor is an unexpected surprise when you bite into a piece of this fudge.

Ingredients Needed

To make this root beer candy you need: 

  • White chocolate chips
  • Marshmallow cream – Also called “marshmallow fluff”
  • Heavy cream
  • Sugar
  • Butter – Unsalted is preferred. If you only have salted, add a bit less additional salt to the fudge recipe.
  • Root beer concentrate – I used McCormick’s brand found near the extracts in the baking aisle at my grocery store.
  • Salt

How to Make Root Beer Float Fudge

STEP 1. In large saucepan, heat sugar, butter, salt and cream until combined. Bring to a boil and stir continuously for 4 minutes.

STEP 2. Remove from heat. Quickly stir in white chocolate and marshmallow. Whisk in vigorously until smooth, be patient this will take a couple minutes. Using an electric mixer yields best results.

STEP 3. Pour half of mixture into a parchment paper lined 13×9 baking dish. To the remaining fudge, whisk in root beer concentrate. Stir until combined.

STEP 4. Pour the root beer fudge over  the layer of white fudge. Using a knife, swirl the two together. Refrigerate 4 hours or overnight. Cut into bite size pieces and enjoy.

Storage Tips

After cutting this fudge into squares, keep it in the fridge until you’re ready to eat it. I LOVE the way it tastes when it’s cold. . . it feels so much more like a root beer float.

However, fudge CAN be stored at room temperature if desired.

Can you make fudge without an electric mixer?

You do not need a mixer for this fudge recipe but it does make it easier. If you’re not using an electric mixer, you’ll need to whisk very vigorously to combine the white chocolate and marshmallow cream into the butter and sugar.

If it seems like it’s not combining well, keep going! It sometimes takes a few minutes. You want to combine it until the fudge texture is silky smooth.

Comments & Reviews

  1. This has now become a staple in my Christmas treat making. Everyone loves it, and the recipe is foolproof. For the second year in a row, it was requested as a birthday treat by the son of one of our good friends, whose birthday is in June. Thank you so much for sharing your genius with the rest of us. You make me look good. 😁

  2. The picture and recipe looks delectable! However, there’s a fail in mentioning how the milk chocolate is flavored with the root beer consentrate. The rootbeer consentrate isn’t what contributes to the rootbeer color as the fudge’s top layer. When I made this recipe, I made the white chocolate fudge as instructed. Then I made chocolate fudge and mixed the rootbeer consentrate into the chocolate fudge.

  3. I can’t wait to try these! Oddly enough I too craved root beer and root beer floats when I was pregnant with my oldest! Thanks for sharing!

  4. Where can I find McCormicks Root Beer Concentrate? I looked at my local grocery store, and couldn’t find it. Maybe I was looking in the wrong aisle? Can’t wait to try it! Thank you!

    1. I’m not sure where you live, but I find it in the baking section (near the vanilla extract). I find it at my local Meijer and Kroger. Maybe see if McCormick.com has a product locater?

  5. Thank you for another great recipe! I made 2 batches of this, 1 for a bake sale and the other for family and gifts. I can’t believe how much this taste just like a root beer float. I can’t wait to try more of your recipes!!

  6. I have LorAnn Root Beer Flavor 2 dram size bottle/ says Highly concentrated flavor… what do you think about using this and how much would you suggest?
    could we not use some brown coloring if we don’t get the color from the flavoring?

    1. I’ve never used that brand, so I’m not sure what to suggest. As for food coloring, you have to make sure you use candy coloring because your chocolate would seize with regular food coloring.

  7. These look so delish…and my boyfriend saw my re-pin of these and immediately said I had to make them lol. Thanks so much for sharing!!!

  8. This was so funny to read, it was like reading the story of my life. I was also addicted to Root Beer Floats during my first pregnancy. I would “drink” mine with a spoon (I liked to make them thick) and loved to skim those ice crystals off and eat those. 🙂 Now I feel an urge to run out to the store for some chocolate chip ice cream and some A&W root beer! lol ….. will definitely try this fudge (something else I love to eat). Thanks!

  9. This fudge was delicious! I think though next time I will add just a bit more root beer. I did not get McCormick’s though it smelled like root beer, was %100 pure root beer extract, but I didn’t get the dark color. The top layer was barely a darker ivory and the root beer flavor was a little too faint. None the less, it was very tasty and everyone else loved it too. Thank you!

  10. I made this tonight but mine did not look like the picture. I followed the instructions exactly but mine did not have the pretty brown color. Also, you could taste the sugar grain. I mixed it until it was very smooth. Do you have any suggestions to help me improve it for the next time?
    Thanks for your awesome blog!

    1. Hi Stacey,
      Couple things. First, I use McCormick Root Beer Flavoring. It’s a very dark color. Most other brands are not as dark, so that could have been why your brown is different?? Which brand did you use?
      Also, did you boil for the full time, at a rolling boil? I know some stovetops vary in heat, there shouldn’t have been any sugar grain once boiled. Maybe next time add a minute or two onto your boil time.
      Hope this helped!

      1. Thanks for the ideas….I will try those. I did not use Mc Cormick’s. I’m going to try again because my kids liked it even with grainy texture…lol. I will let you know how it goes. BTW, I love your blog!!!

  11. These look so good! Why can’t I have you as a neighbor?? 🙂 And I’ve never heard of root beer concentrate, where have I been?!

  12. We just finished our batch – it’s delicious! But my root beer layer isn’t brown, it’s white – so we don’t have the pretty effect. I just looked at my bottle of extract – it’s Watkins. Maybe that’s the difference? Next time, we’ll toss in a drop of brown food coloring.


  13. Aimee, I have made five batches of this and it is HEAVEN. This will be my go to dessert for EVER now! I made a batch with the Watkins concentrate and it was not as flavorful I thought and the lightness just made me feel that it wasn’t as RootBeer-y… I also used the extract, but mistake, so you’re right McCormicks is the way to go. My honey lives in Georgia and I sent him half a batch of these and he begged for more. Glamour magazine has their “engagement chicken”… I think this is engagement fudge! Thank you SO MUCH for sharing this!!

  14. We used Watkins, and I don’t think it was that dark. That may be the downfall. We thought maybe it wasn’t enough, because it seems like 3 teaspoons isn’t enough to color half of that recipe. Maybe we will try the McCormick next time we try. I hope that makes the difference! The fudge in the picture is so pretty! Thank you for trying to help me figure this out 🙂

  15. I used McCormick Root beer concentrate, it’s a dark brown liquid, so it naturally colored the fudge. Was your concentrate brown or clear, I guess that would make a difference!

  16. It wasn’t that it wouldn’t swirl. The half that I added the rootbeer concentrate to just stayed white, so it’s all one color. I’m not sure what I did wrong. It’s like the concentrate didn’t make the half brown.

  17. Kathryn, I use concentrate as well. I’m assuming when you say it wasn’t swirled, was it just a brown color from the concentrate?

    I separated half the white fudge out before adding the concentrate, thus when I poured the brown fudge over the white I swirled them together. Hope that helps!!!

  18. We tried your recipe today! I have a question. We didn’t get the two different colors with ours. We used rootbeer concentrate, because we couldn’t find extract. Is that the reason for the color difference? It tastes excelent, but I would love to have that swirled effect. Any help you could give would be outstanding! Thanks!

  19. Aimee – do you mind if I share this recipe on my blog (I’ll be sure to attribute it to you, of course!)? I made it to send to my mom who’s in hospital and she loved it! It’s such a great idea!

  25. Oh, yum! I love root beer! Wish you were my neighbor just to get a taste. I’m afraid what would happen if I made these…I might eat them all!

    I would love it if you linked up to my Hi-5 Friday party.

  26. i craved root beer during pregnancy too, sooo weird. And so did my sister in law. Whoa, I wonder if there’s some wives tale to this… Anyway, these look AMAZINGLY delish!!! We love fudge, all kinds!

  30. I am on a root beer kick right now! I just had homemade root beer (at a restaurant) last weekend and that is all I am thinking about. Where do you buy the extract? Is that just a Walmart? I will have to start looking around for it!

  31. Holy cow, this looks awesome. Fudge and me, we’re the best of friends. I’ll definitely be giving this a try! Thanks!

  32. I just made this last night for my mom, who loves root beer and needs a pick-me-up – she goes into the hospital this week and I know these will brighten her day!

  33. This recipe looks amazing! Join in on the fun and come over to Cast Party Wednesday tomorrow to share this tasty recipe with us.
    I hope to see you there!

  34. I cracked up when I read the first sentence of this post, because I, too, had an addiction to root beer floats with my first child. She is only three, though, so not quite in the distant past. I cannot wait to try these! I have everything except the root beer extract, so I’m adding it to my grocery list. This recipe sounds worth the splurge!

  35. Wow yum! Sounds so good….maybe cause I’m 3 months pregnant haha. Gonna try these. Could I use Root beer concentrate instead of extract? Found you at Tasty Tuesday, check my lil blog out: www.mykidsdinner.blogspot.com

    1. Hi – I made these last night and my rootbeer 1/2 came out beige. Is there a secret to getting it brown like the picture? They are amazing though!! Thanks!

      1. Some brands of root beer flavoring are clear. I used McCormick which is a brown colored flavoring. That’s my only secret 🙂

        1. I just finished making these with Watkins root beer extract, which is brown, but it came out mostly beige too :/ I’ll have to use McCormick’s next time!

  36. Just stoppin’ by from Tasty Tuesday and I must say that fudge looks divine! I’m sure it’s very tasty and one I’m going to bookmark and make sometime. Thanks for sharing!

  37. are you kidding me with this! YUM! and what a brilliant idea!

    I would love it if you would share this and/or any other projects you have been up to at Tuesday Talent Show at Chef In Training Tomorrow! Plus there is going to be a fun giveaway too! Thanks so much and I hope to see you there!
