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!

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).
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.
