Marshmallow Fluff Never-Fail Fudge has always been a hit in my home.

Fluff Never-Fail Fudge

It probably helps that Marshmallow Fluff is a New England tradition that my mom, born in the southern Boston area, carried into my family’s Florida home. (And I’m so thankful!)

Have no idea what all the fuss over Marshmallow Fluff is?

Well, before I start sharing my favorite fudge recipe, let’s take a trip to New England and see what makes this wicked good marshmallow cream so, well… wicked good!

Nuthin’ But The Fluff

Fluff marshmallow cream was first sold in 1920 by 2 World War I veterans named H. Allen Durkee and Fred L Mower:

  • They bought the Marshmallow Fluff recipe for $500 from a man named Archibald Query, who invented it in 1917 but had a difficult time getting his sugar-based confection off the ground during an era of wartime rations.
  • Durkee and Mower built a very successful door-to-door business selling their Marshmallow Fluff throughout New England, and by 1927 were advertising their delicious white cream in Boston newspapers.
  • The popularity of their brand spread in the 1930s as Marshmallow Fluff ads took to the radio and promotional efforts reached hundreds of thousands of homes.
  • When Durkee-Mower joined forces with Nestle in 1956, the brand became a nationwide hit. What helped fuel the popularity of Marshmallow Fluff?
  • As the 1950s rolled on, the delicious, easy-to-make Marshmallow Fluff Never-Fail Fudge recipe was printed in magazines such as Ladies Home Journal.
  • The Fluff fudge recipe combined the famous marshmallow cream and Nestle’s chocolate bits, lifting sales for both halves of that delectable dynamic duo.
  • The family of Marshmallow Fluff recipes grew in 1966 when the Rice Krispies Marshmallow Treat recipe was published. The simple, delicious Rice Krispies marshmallow bars were an instant hit and is still popular all these years later.

But what makes Marshmallow Fluff stand a puff above the other marshmallow creams you’ll probably find in your local grocer’s sugar aisle?

Durkee-Mower says they use a “batch-whipping process,” which they claim is the only marshmallow cream still made that way. Batch-whipping makes a smooth, fluffy product that is as fun to look at as it is to eat.

Fellow natural-foods fans like me will also be glad to know Marshmallow Fluff contains no artificial preservatives.

The Marshmallow Fluff Never Fail Fudge Recipe

There are too many tasty Marshmallow Fluff recipes around these days to count. But I can easily tell you which is my favorite: Marshmallow Fluff Never-Fail Fudge.

I don’t consider myself a chef by any stretch of the imagination, but I can tell you that Never-Fail Fudge is about as easy to make as its name would suggest.

Almost as easy, that is!

You see, I’ve made a few blunders over the years making Fluff Never-Fail Fudge. I blame it not on the fudge recipe but rather on my being loosey-goosey with the preparation process.

The Fluff fudge recipe is really simple, and it requires a short list of ingredients — many of which you probably already have in your kitchen.


Here’s what you’ll need to make a tasty batch of Never-Fail Fudge:

  • 7-1/2-ounce jar of Marshmallow Fluff
  • 2-1/2 cups of sugar
  • 1/4 cup of butter or margarine (I say go for the butter!)
  • 5 ounces of evaporated milk
  • 1/4 teaspoon salt
  • 3/4 teaspoon of vanilla
  • 12 ounces of semi-sweet chocolate pieces
  • Optional: chopped walnuts or other flavorful additions

The first 5 ingredients should be combined into a large pot (I use a 3-quart pot) over low heat.

Stir the contents until everything is well blended, and then turn the heat up to moderate, letting the blend boil for about 5 minutes. Candy experts would tell you to let the fudge mixture get to soft ball stage, but at this point I’m not that culinarily attuned!

Once the mixture has boiled for 5 minutes, remove the fudge mix from the heat and immediately add the vanilla, chocolate bits, and chopped walnuts (or other tasty modifications if applicable), blending everything thoroughly.

Let the fudge cool in the pan for at least 2 hours (or 45 minutes to 1 hour in the refrigerator).

Cut into slices, and enjoy!

4 Tips For The Tastiest Marshmallow Fluff Fudge

I’ve made Never-Fail Fudge so many times now that I’ve also stumbled over making the fudge more than once, too.

Fluff Never-Fail Fudge

Here are 4 personal tips that I’ve learned from trial and error:

  1. When the recipe says you should be “stirring constantly,” they aren’t joking! One time, I left the boiling pre-chocolate fudge mixture unattended in the pot for about 15 seconds to answer a phone call. By the time I came back, I had already smelled the tale-tell odor of caramelizing sugar. Surely enough, I scalded the mixture and left it with an irreversible burnt flavor.
  2. I used to go a little over-the-top with adding the vanilla. If a recipe called for a teaspoon of vanilla, I would add a teaspoon and a third — or a teaspoon and a half. I once added a bit too much vanilla to a batch of Marshmallow Fluff Fudge. As you’d guess, it tasted like it was spiked with alcohol. The fudge tasted way off and I didn’t even want to touch the rest of that batch.
  3. Make sure the chocolate bits are well stirred, because you don’t want to leave chunks behind. You’ll want to avoid streaking of the chocolate, too. One time when I was in my 20s I got impatient stirring the chocolate fudge mix. What ended up happening was the chocolate fudge set up unevenly in the pan. This affected the texture and flavor of the fudge, and it was a total loss.
  4. Some people grease their fudge pans, others use wax paper. I prefer buttering the pan simply because it’s a little cheaper and it eliminates the risk of wax paper chemicals leaching into the fudge.
