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.

I tried this today. I modified the amount of sugar to 1/3 cup powdered sugar but did everything else as directed and it’s freaking fantastic fudge. I will make again. Thank you.

can you use sweetened condensed milk? I think I've used it a long time ago and it was terrific

Condensed milk IS amazing but you will need different amounts of ingredients because it is a different thickness and texture and it is very sweet. Try it and try to adjust the other ingredients (no or less sugar, less milk, no or less marshmallow fluff), or look for a peanut butter fudge recipe with that, if that's what you prefer.
