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.

made them today and while a very simple recipe I must have messed up somewhere because they are very crumbly. They still taste great and they will be eaten and enjoyed I just wish I knew what I did wrong. I’m thinking I over mixed because when I took the boiling mixture off the stove I had the peanut butter and fluff in a bowl already weighed out but it just wasn’t really melting with the sugar/milk mixture but it was combining. Would maybe slightly warming up the peanut butter and fluff before adding it into the sugar milk mixture help? It is winter where I am maybe they were just colder than they normally would be. I also used lactose free milk, it was still whole milk though so idk if lactose is important or not.

How do I storage this, I don't have to leave it in the fridge do I?

Since it is made with milk, I recommend keeping it out no longer than half a day before storing it in the fridge, then taking out a few pieces and letting them come to room temperature before serving, or up to a day. But please consult with the latest food safety recommendations and your healthcare providers because everyone's stomach has different sensitivities.

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.

Is it a rolling boil for 3 minutes?

A gentle boil, make sure to stir constantly so the bottom of the milk doesn't burn onto the pot.
