Instead of butter can you use margarine?

This was so fast and easy just what I was looking for me and my mom made it together thank you.

Great, great recipe. Only need a few ingredients and that is what I love plus the recipe is delicious. I whip this up in minutes when that sweet tooth hits! Easy, few ingredients, tastes great. What more do you need? Definitely recommend!

Thank you so very much!! Easy,fast and delicious!! I have tried to make peanut butter fudge for years! I have always failed. This is the best recipe ever! Hats off to the chef!!

Came out great. For those saying it was grainy, try stirring every so often while you are heating the sugar and when it starts boiling. Make sure you work fast once you start mixing as it sets quick!

I add 1/4 stick butter and a few marshmallows while it's boiling, I also add a full cup peanut butter it makes the fudge firmer.

It was SUPER easy to make I had been looking for awhile for an easy fudge recipe and it turned out DELISH!!!

Love this one and it is so easy added a little more peanut butter. My family loved it.

I first saw this recipe on here maybe 2 years ago. Since then this has become the thing I am known for and I have to bring it to every family get together or people get mad at me! Haha! Sometimes I add mini marshmallows or marshmallow cream, but if I am out of those I just add an extra tablespoon of milk at the beginning and that gives it the creamy texture! Love this recipe!!

Very good! :p

Just made the peanut butter candy! It was so easy and so tasty. I'll make this again. Thanks.

This is by far the best p'nut butter fudge I have ever made... It is perfect... I only added two diced marshmellows... And I used my 100% lactose free milk... Thank you so very much... Carol from Georgia

I read all the comments before I made this, I added a tablespoon of marshmellow creme. This was so easy to make and it tastes sooo good!!!

Very good recipe. Quite sweet, but very peanut buttery. For those who had problems with it being grainy, do not stir the sugar/milk mixture while it boils. Also don't scrape the sides too much. Gently brush down the sides of the pot with a damp pastry brush or spatula. Simply scraping the sides into the pot will cause the mixture to seize and will crystallize, ruining the whole batch.

Just made this, was very easy to make. Hubby will be surprised, he loves peanut butter fudge. Hope it is good.
