I believe almost each of us has one recipe that identifies us. For my mom, it was Nordy Bars and this Almond Roca Recipe for my Nana. For my friend Anne, it is her Aunt Barbara’s Old-Fashioned Fudge.

This recipe uses marshmallows, but if you need a recipe that uses marshmallow creme, check out our Fantasy Fudge recipe.

How to Prevent Grainy Fudge

Heating the ingredients too quickly over high heat will produce a grainy fudge that is dry and will be crumbly. To prevent this from happening, heat consistently over medium heat and pay attention to the instructions when it directs you to stir the ingredients (and for how long).

Allow the sugar to fully dissolve before it comes to a rolling boil to prevent grainy, gritty, and crunchy fudge.

Updated for fall 2022: I have used Costco’s organic sugar for years to make this fudge. But in fall of 2022, they changed the formula or something and the sugar will no longer dissolve completely in this recipe.

After four ruined batches, I can no longer recommend Costco’s organic sugar for this recipe.

Additionally, using lower-quality chocolate which contains a lot of filler can produce a grainy fudge. When I used vegan marshmallows to make this chocolate fudge recipe for a vegetarian friend, I did notice the texture was drier than normal.

How Long Does it Take For Christmas Fudge To Set?

This easy fudge recipe will be completely set within 45 minutes under normal kitchen conditions. Warmer kitchens or climates may impact the cooling time. That being said, many people I know prefer eating the fudge warm before it has fully cooled. To each their own!

Pro Tips/Recipe Notes for Old-Fashioned Fudge

  • Use a lightweight but large(ish) saucepan. The first time I made this I used an enameled cast iron dutch oven and it was bonkers awkward and heavy to pour the fudge one-handed. I now use this saucepan.
  • I have tried using vegan marshmallows and while it turned out ok, the texture was not as creamy as traditional marshmallows.
  • Top it with Dehydrated Marshmallows for a fun and crispy surprise topping.
  • Need to use up some of the leftover evaporated milk? Try Slow Cooker Hot Chocolate or Cinnamon Pancakes. Or, just do like we do…and make another batch of fudge. 🙂

  1. Wow, I was given these as a gift and the only complaint is that I had to split them up so I could enjoy them for longer 😂. I have never had fudge that is so smooth and so delicious. Thank you to the gift giver and, now, for the recipe so I can now make them and share the yumminess!5 stars

  2. Made this recipe today and it is absolutely DELICIOUS!!! It was much better than I was expecting. I will definitely be making this again 🙂 5 stars

    1. I’m so glad you loved it so much, Shannon! I always made fudge in December, and now I think you’ve inspired me to also make it a summer dessert. 🙂

  3. This was the first time I had ever made fudge and the process was very easy with your instructions. Came out great and had lots of positive feedback from those we gifted it to. Thanks for a great recipe!5 stars

  4. Do you think this is gluten free? I was making treats for friends when I remembered that they only eat gluten free. I’m wondering if marshmallows are gluten? I’m clueless about special diets. 

    1. Marshmallows are gluten-free as are chocolate chips. I’d double check your own ingredients on your brands to make sure, but you should be fine for this recipe.

  5. Easy and so creamy and good! Thank you! We did a test batch and are going to be making more to share with teachers. There is debate at our house is over if I should put crushed up peppermint sticks or sea salt on it. 🙂5 stars
