Easy Peanut Butter Fudge Recipe

I don’t know if I’ve ever confessed this before, but peanut butter isn’t my favorite ingredient. I enjoy an occasional peanut butter treat, like Peanut Butter Bars or Peanut Butter Rice Krispie Treats but there are other flavors I prefer. I will admit though to loving a good, chewy peanut butter cookie!

This fudge though? This is good enough to change my opinion on peanut butter desserts.

The creamy peanut butter fudge combined with an occasional chewy marshmallow and crunch of peanuts…oh my!

I’m usually all about covering my peanut butter desserts with melted chocolate, folding in chocolate chips or finding some other way to add chocolate to the treats.

Not this time. The peanut butter and marshmallow stand on their own.

My kids agreed that this spin on peanut butter fudge is made extra delicious thanks to all the marshmallows you fold in! We polished off the whole pan within a day. . .and I’m already craving it again.

No candy thermometer needed. You don’t need to be some kind of candy making genius. Follow the steps and you’ll be just fine.

Ingredient Notes

Ingredients needed to make fluffernutter fudge.
  • Heavy Whipping Cream– be sure to use the full fat cream, don’t substitute with evaporated milk or half and half here.
  • Butter- for best results, we use unsalted butter and add in kosher salt. This allows us to control the amount of salt, as each brand of salted butter varies.
  • Marshmallow Cream– this gives the fudge it’s soft texture. Use our homemade marshmallow fluff for delicious results.
  • Peanut butter- Choose a shelf stable peanut butter when making fudge, Jif and Skippy are perfect.

How to Make Fluffernutter Fudge

Here’s how to make your own addictively scrumptious homemade peanut fudge.

  1. Prep the pan. We like to use parchment paper, but foil will work too.
  2. Set aside white chocolate, peanut butter, and marshmallow cream in a bowl.
  3. Heat it up. Bring sugar, butter, and cream to a ROLLING boil and stir continuously for 4 minutes (set your timer)!
  4. Remove from heat. Quickly pour hot mixture into the large mixing bowl with the other ingredients. Mix for one minute, until smooth.
  5. Fold in mini marshmallows and peanuts. Pour fudge into prepared pan and let it set for 3 hours, until hardened.
  6. Serve. Cut into bite sized pieces.

Tips and Tricks

  • Mini marshmallows are my preference.  They melt much more quickly than full sized marshmallows and you want the unmelted ones small enough to bite into! If you can’t get miniatures, use full size marshmallows and chop them into bite sized pieces before proceeding with the recipe.
  • Variations: I think this fluffernutter candy is delicious all on its own. If you’re like I usually am and can’t resist adding chocolate to everything, you could certainly top this with a layer of melted dark chocolate! White chocolate would taste great on top of this fudge too if you’re so inclined.
  • Storing: I keep this in an airtight container at room temperature. If your house runs warm you might want to store it in the refrigerator instead.
