Root Beer Float Fudge

Root Beer Float Fudge: soft, sweet fudge with a root beer and vanilla swirl

When I was pregnant with my first child I had an addiction to root beer floats. I was also addicted to gyros and fat french fries, but those I couldn’t make at home every night! It’s hard to believe that was over 14 years ago. Man, I’m old. Just the reality of that makes me want to grab another bite of these fudge pieces.

I can’t even begin to describe how delicious these taste. One, because I’m a horrible writer…two, because you just have to try them to understand how unique they are! If you eat them cold you may even convince yourself, just a little bit, that you are eating the crunchy part of a root beer float (you know the ice cream with the frozen root beer crystals, yum)!

Root Beer Float Fudge: soft, sweet fudge with a root beer and vanilla swirl

These were a huge hit in my family. So much so that I’m not sure I should ever make them again. I ate way more than my share, more than several people’s share. Ahhh, but it was so good. And it brought me back to being pregnant with my oldest child. And for just a moment I felt young again. Until I opened my eyes and realized I had 8 loads of laundry to do,  dog puke on the carpet to clean up, and 18 extra pounds on my hips.

Root Beer Float Fudge

Root Beer Float Fudge


  • 3 cup granulated sugar
  • ยพ cup unsalted butter
  • 1 cup heavy cream
  • pinch of salt
  • 3 cup white chocolate morsels
  • 1ยฝ cup marshmallow cream
  • 3 tsp root beer concentrate (I use McCormicks)


  1. In large saucepan, heat sugar, butter, salt and cream until combined. Bring to a boil and stir continuously for 4 minutes.
  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.
  3. Pour half of mixture into a parchment paper lined 13x9 baking dish. To remaining fudge, whisk in root beer concentrate. Stir until combined. Pour over white fudge. Using a knife, swirl the two together. Refrigerate 4 hours or overnight. Cut into bite size pieces and enjoy. Tastes great cold!

  21. 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!

    Sweet Stella’s

  42. Who’d have thought you could make root beer float fudge?!?! You are a genius! I am pinning this! Thank you! So excited to try these!

  43. 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!

  44. Kathryn

    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!

  45. 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!!!

  46. Kathryn

    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.

  47. 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!

  48. Kathryn

    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 ๐Ÿ™‚

  49. 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!!

  50. haha! Jennifer- I’m so glad you enjoyed it. Good info on the flavorings. I’ve only used the McCormicks!

  51. Anonymous

    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.


  52. These look so good! Why can’t I have you as a neighbor?? ๐Ÿ™‚ And I’ve never heard of root beer concentrate, where have I been?!

  53. Stacey

    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!

    • 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!

      • Stacey

        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!!!

  54. Jen

    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!

  55. Karen

    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. ๐Ÿ™‚ 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!

  56. 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!!!

  57. Beverly

    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?

  58. Teresa

    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!!

  59. angela

    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!

  60. 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!

    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.

  65. bobbie

    I used watkins brand of rootbeer consentrate. This consentrate is also dark brown but didn’t turn the fudge color brown.

    How would I stop myself from eating the whole cup?
