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.

Could the peanut butter be substituted for chocolate chips? I made this today with peanut butter and it is so so good! Was hoping to make a variety tray of fudge and I really like this recipe.

Hi Allyson, I'm so glad you like this fudge recipe! I don't think the peanut butter can be substituted for chocolate chips directly, since chocolate chips will be hard when they cool down after being melted, while peanut butter is buttery. You might need to add a little bit more milk or marshmallow creme if using chocolate chips, but I am not sure exactly how much without testing it out myself.

I just made this recipe and this fudge is just so yummy. I used crunchy peanut butter instead of creamy because I like some nuts in my fudge and it turned out perfect. Thank you for a great easy to make recipe.
