Amazingly Easy Peanut Butter Fudge

This old fashioned peanut butter fudge recipe is light and creamy, and amazingly simple! No one would ever guess that it only requires four ingredients, one pot, and a few minutes of cooking time.

Easy peanut butter fudge

Every time I make this peanut butter fudge, I feel like I'd died and gone to a sweet, peanut-buttery heaven where I danced among unicorns and fluffy white clouds.

So I am sharing this super easy peanut butter fudge recipe from a family cookbook.

This fudge recipe is the best because:

  • There are only four simple ingredients!
  • It's made in only one pot!
  • And the instructions are only two sentences long!

So if you've always envisioned the peanut butter fudge-making process as being something complex, requiring candy thermometers and special sugars, and perhaps a little bit of fairy dust... let me show you how easy it is to make peanut butter fudge!

Best Peanut Butter for Peanut Butter Fudge:

As much as I love natural peanut butter, you don't want to use it in this recipe. Stick with traditional creamy peanut butter (I almost always use Jif).

Fudge making tip:

The fudge-making process works best if you put the marshmallow fluff and peanut butter into bowls (as pictured above) before adding them to the milk/sugar mixture. That way you can add them quickly and make sure everything melts together without separation.

My daughter and I tried this recipe and it did not do right. We followed recipe as directed and before we could get the candy out of the pot it set up and it was so crumbly . we had to trash it

I'm sorry to hear that! Without being in your kitchen to see what went wrong, the only thing I can ask is to double check that you got all the ingredients (full fat peanut butter, whole milk, etc) and amounts correct, as well as making sure that all the steps were followed to completion (bringing to a boil, stirring constantly for 3 full minutes, etc). I hope you give this another try!

This is just like the peanut butter fudge that my Great Aunt Elsie used to make for my cousins and me!! Delicious and it sent me back in time 50 years!! Ha! :)

I made this fudge last night, and it’s very creamy and tasty! I only had marshmallows, so I just weighed out 7 oz., and stirred them in before the peanut butter, until they melted.

I love this recipe and it is so easy and delicious but I have been cutting back on the sugar and carbs and I was wondering if you could use allulose sweetener in place of the sugar. It's the only sugar substitute that me and my family have found that actually tastes like regular sugar and my husband and kids are very picky about the taste lol
