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.

When I was a little girl, my grandmother's sister used to make a big batch of peanut butter fudge every year during the holidays. I hadn't thought it was possible for anything to taste that good! It felt like I'd died and gone to a sweet, peanut-buttery heaven where I danced among unicorns and fluffy white clouds.

I 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.

So when I came across this super easy peanut butter fudge recipe in a family cookbook years later, I was shocked to say the least.

  • There were only four simple ingredients!
  • Only one pot!
  • And the instructions were only two sentences long!

I was so excited to know it was that simple to replicate the fudge I'd fantasized about for so many years. Sure enough, the batch I made came out every bit as delicious as the one from my grandma's sister, and now I knew I could have my favorite fudge whenever my heart desired.

Soon I became famous amongst my friends for this delightful peanut butter fudge. And, just like my great aunt, I never let on how easy it was to make.

Just a container of marshmallow fluff (or marshmallow creme), some good old fashioned creamy peanut butter, milk, and sugar. The secret's out, and I can't wait for y'all to make this yourselves.

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 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.

Question…. Mine has been in the fridge for most of the day and it hasn’t hardened yet any suggestions on what I did wrong??


Friday 14th of October 2022

Hmm, I am not sure, I've never had that happen.. Did you measure the ingredients correctly? Perhaps let it simmer for a few minutes next time to let it thicken/evaporate?

I followed this recipe exactly, and had my phone time me for exactly three minutes, but the fudge was dry and crumbly. The sugar and milk mixture was boiling to a foaming froth for the three minutes, so I'm thinking it was too hot for the three minutes? It began getting hard immediately when putting in the marshmallow creme and peanut butter. Any suggestions?
