Why This Recipe

This marshmallow fluff fudge recipe shines because it emphasizes simplicity without sacrificing flavor:

  • Many other recipes call for margarine, which may not provide the same creamy richness. Our recipe sticks with butter to deliver a smoother and more indulgent result.
  • Another unique aspect of this marshmallow fluff fudge recipe is how well it stores and holds its texture. This makes it ideal for preparing ahead of time for holidays or special events. While many fudge recipes tend to dry out or become crumbly over time, this one remains soft and creamy for weeks when properly stored.
  • This recipe stays soft and creamy over time thanks to the marshmallow fluff, which stabilizes the fudge, and the rich combination of butter and evaporated milk that locks in moisture​.

Marshmallow Fluff Fudge Ingredients

Marshmallow Fluff Fudge raw ingredients that are labeled

You’ll need:

  • ¾ cup (12 tablespoons) of salted sweet cream butter
  • ¾ cup of evaporated milk
  • 3 cups of granulated sugar
  • 1 (12-ounce) package of semi-sweet chocolate chips (I used Nestle)
  • 2 teaspoons of pure vanilla extract
  • 1 (7-ounce) container of marshmallow fluff (I used Jet-Puffed)
  • ⅔ cup of finely chopped walnuts

Substitutions And Additions

NUTS: You can substitute any chopped nuts for the chopped walnuts in this creamy fudge.

CHOCOLATE CHIPS: You can substitute milk chocolate or dark chocolate chips for semi-sweet chocolate chips in this marshmallow cream fudge recipe.

BUTTER: Do not substitute margarine for butter. Margarine has a high water content.

The fudge may not set properly if you use margarine, and it will not have the texture you are hoping for.

EVAPORATED MILK: You can substitute half and half for the evaporated milk in this easy recipe.

How To Make This Marshmallow Fluff Fudge Recipe

Once you combine the simple ingredients needed to make this sweet treat, spread it in your baking pan and let it chill until it is set. From there, all you need to do is slice and indulge!

STEP ONE: Line an 8×8 square pan with parchment paper, be sure the paper goes up along the sides of the baking dish with a bit of overhang.

The parchment paper makes cleaning up a snap and makes it much easier to remove from your pan when it’s time to slice into squares.

STEP TWO: Add the butter to a 4 to 5-quart heavy-bottomed saucepan over medium heat.

Attach a candy thermometer to the side of the saucepan to keep a more accurate temperature reading.

Allow the butter to melt, then add the evaporated milk and granulated sugar. Stir constantly, even after the sugar melts, until the thermometer reaches 235°F (the softball stage).

PRO TIP: To test the boiling mixture for doneness without a thermometer, drop a bit of it into a bowl of cold water. If it forms a ball that is soft enough to flatten between your fingers, the mixture is ready for cooling – this is called the softball stage.

Remove the saucepan from the heat.

STEP THREE: Quickly stir in the chocolate chips. Add the vanilla and marshmallow fluff once the chocolate chips have melted.

Keep stirring until the marshmallow fluff is completely incorporated. Stir in the chopped walnuts.

STEP FOUR: Carefully pour the fudge mixture into the prepared pan. Tap the sides of the baking dish to release any bubbles.

Allow the fudge to rest for 30 minutes. Chill the fudge in the refrigerator for at least three hours before slicing six rows by six rows.

Keep refrigerated until ready to serve.

This delectable fudge also makes excellent homemade holiday gifts. Add it to a cookie tin along with our eggnog fudge and gingerbread fudge for a trio of treats.

Storage

Whether you’re making it ahead for a special occasion or simply looking to savor it over time, here’s the scoop on storing your fudge:

MAKE AHEAD: Prepare the fudge as directed, then allow it to cool completely in the pan. Once cooled, cover it tightly with plastic wrap or aluminum foil, ensuring there’s no exposure to air.

You can store it at room temperature for up to one week, so it’s ready to enjoy whenever those cravings hit.

IN THE FRIDGE: Store any leftover fudge in an airtight container in the refrigerator for up to three weeks. 

IN THE FREEZER: You can freeze this chocolate marshmallow fudge for up to three months. Allow the fudge to thaw overnight in the refrigerator before serving.

Frequently Asked Questions

How can I make this fudge less sweet?

If you prefer a less sweet fudge, you can try using bittersweet chocolate chips or reduce the amount of marshmallow fluff in the recipe slightly.

Why did my fudge turn out grainy?

Grainy fudge can happen if the sugar crystals don’t fully dissolve during cooking. Ensure you stir continuously and cook over low heat to prevent this issue. Also, avoid using powdered sugar, as it can lead to grainy fudge.

How do I slice chilled fudge easily?

To easily slice the fudge, dip a large sharp flat knife in boiling water, dry it completely, and cut one long slice (the heat will help the blade to glide through).

The sweetness of the marshmallow fluff perfectly complements the richness of the chocolate, and the crunch of the nuts makes this treat irresistible! With a delightfully creamy texture, this marshmallow fluff fudge is going to be a favorite treat any time of the year.

Ingredients
  

  • ¾ cup salted sweet cream butter (12 tablespoons)
  • ¾ cup evaporated milk
  • 3 cups granulated sugar
  • 12 ounces semi-sweet chocolate chips (I used Nestle)
  • 2 teaspoons pure vanilla extract
  • 7 ounces marshmallow fluff (I used Jet-Puffed)
  • cup chopped walnuts

Instructions
 

  • Line an 8×8 baking dish with parchment paper, be sure the paper goes up along the sides of the baking dish with a bit of overhang.
  • Add the butter to a 4 to 5-quart heavy-bottomed saucepan over medium heat. (Attach a candy thermometer to the side of the saucepan to keep a more accurate temperature reading.) Allow the butter to melt, then add the evaporated milk and granulated sugar. Stir constantly, even after the sugar melts, until the thermometer reaches 235°F (the softball stage). Remove the saucepan from the heat.
  • Quickly stir in the chocolate chips. Once the chocolate chips have melted, add the vanilla and the marshmallow fluff. Keep stirring until the marshmallow fluff is completely incorporated. Stir in the chopped walnuts.
  • Carefully pour the fudge into the prepared baking dish. Tap the sides of the baking dish to release any bubbles. Allow the fudge to rest for 30 minutes. Chill the fudge in the refrigerator for at least 3 hours before slicing 6 rows x 6 rows. Keep refrigerated until ready to serve.

Notes

  • The parchment paper makes cleaning up a snap and makes it much easier to remove from your pan when it’s time to slice into squares.
  • To test the boiling mixture for doneness without a thermometer, drop a bit of it into a bowl of cold water.
    If it forms a ball that is soft enough to flatten between your fingers, the mixture is ready for cooling – this is called the softball stage.
  • Score the top of the marshmallow creme fudge with a sharp knife before chilling to make cutting easier.
  • If you are freezing the homemade fudge, wrap the un-cut fudge in wax paper and then plastic wrap or aluminum foil. This can help keep the chocolate from slight crystallization from forming.
