Next, in a medium pan, stir together the sugar and the milk. Over medium-low heat, bring the mixture to a boil.

Continue to boil for 2 ½ minutes, stirring continuously to prevent sticking.

  1. Tried the easy pb fudge recipe and it was absolutely delicious. Now wonder if there is an easy chocolate fudge that is that easy and delicious

  2. Just made it, had to scrape the pan out afterwards. For taste testing of course. ☺ It’s super smooth and not at all gritty on the tongue. It’s setting very well too.

  3. My grandmas passed down recipe is the same except we use a full cup of peanut butter and we use water instead of milk. It’s been a family favorite forever! I just made a pan.

  4. Just made a batch of the yumyum

  5. Just made a batch of the yumyum
    Just like I use to make as a kid perfect

  6. This was so easy and so, so delicious!! I’ve previously made fudge with the stress of figuring out the soft-ball stage, and I loved that this had the same results without any of that! Thank you 🙂

  7. Great recipe!! I followed the directions exactly but mine was overcooked so it is a bit dry and crumbly. However that could be the pan I’m using or heat level. It’s still delicious.  Next time I will cut 30 seconds off the boiling time.

    • Next time it starts setting up too quickly in the pan just add a tablespoon or 2 of milk. Keep stirring it and adding until its smooth. When its the consistency of cake icing pour it into the pan to set up.

  8. I made this fudge. It is quick and easy. It is, however, magic fudge because it has vanished!!  I melted milk chocolate and poured it on the top just for fun and everyone loved it. 

  9. Damn good!!!!

  10. I made it, its delicious, thankyou, I would love a chocolate one also

  11. I made this one for the first time and my go-to one (powdered sugar, butter, and peanut butter) as well. I am bringing them both to work and have a peanut butter fudge taste test. Excited to see the results.

  12. I just made a batch and it is awesome. This will be put in my recipe box! Thank you!

    • Wow, so good and so easy. This is the second batch I’ve made in 2 days. :). Any update on an easy chocolate fudge like this fudge?

  13. Oh my, absolutely delicious, so easy my husband did it, only problem, he now considers himself a Chef.

  14. Tried this for National Peanut Butter Fudge day on Nov 20. Sooo easy and soooo good. I halved the recipe easily and now hope we still have some left for tomorrow! Thanks for an easy recipe.

  15. good…just not the best fudge recipe….I like the recipe on the back of the “KRAFT Marshmallow cream Jar much  better….Its so much more creamier(Sorry)…and I prefer to add  chopped walnuts or pecans.

  16. I just made this recipe and it turned out so good! Everybody loved it so I’ll be making a double batch next! Thanks so much!!

  17. Just made this but substituted egg nog for the milk. Turned out really good!!

  18. Can this be made with Splenda?

  19. This is the exact recipe my nana (great grandma) and I made together when I was little. She passed when I was 15 and now I’m 22. I never had the recipe written down, but my mom knew it by heart. The first time I made it alone my mom was in the phone with me telling me exactly what to do. Every following time I always missed something or didn’t cook long enough, or something. My mom passed when I was 18 and I still never had the recipe written down. I want to thank you so much for posting this. It is exactly as it should be and it is the exact recipe. I have finally made it again and it is right. My nana always over cooked it a bit and I will too but that’s because it’s just so dang good. I’d rather it crumble that need a spoon!!!

  20. This is like the fudge my Mom made, I make, and my Daughter now makes. We use larger quantities so it’s easy to remember. 3 cups sugar, 1 cup cream, 1 cup peanut butter.  Boil 3 minutes take off heat add 1 tsp. Vanilla, beat and pour in buttered pan. Delicious 

  21. I add about two tablespoons of better and used evaporated milk , turned out really good.

  22. SO GOOD

  23. My family is having it now!!!!!

  24. All my life I’ve made old fashion fudge,never made peanutbutter fudge. I thought I’d give it a try… Fabulous. Everyone loves it & so easy. Thank you

  25. Tasty and easy to make . Thanks !

  26. I’m out of milk is sweet condensed milk too sweet to use instead ?

  27. It is cooling as I type. Looks like and tastes like it will be amazing. What really surprised me was that clean up was a breeze as well…

  28. Second time in my life I’ve made fudge, it’s cooling now❤️ Clean up a breeze and quick and easy. Had everything on hand! Licking the spoon tells me it’s going to be great. Hope it sets up ok. Nothing is mentioned about refrigeration ?

  29. How long does it take it to harden..? It’s been in the fridge for a few hours at this point and it is very bendy.
    The fudge came to a super duper slow boil, so I am not sure if I started the “2.5 minute” timer at the right time. If I messed up or whatever, can I place it in the freezer to harden in, or will it get messy when I take it out?

  30. How will it turn out without the vanilla? My husband has an allergy but loves peanut butter anything

  31. It was more like taffy in a way when I tried it. Did I do something wrong?

  32. I made for the 1st time. Was not as dry as I like. Everyone liked it. I Read to boil it l9nger for dryer fudge. I will boil longer next time, ty all for nice reafing. Was so eady. My chocolate is just a bag of chocolate chips [toll house] 1 can condenced milk tsp vanilla. Melp & pour in dish. Very creamy and yummy ♡

  33. I just got done making it! The 2nd time in two weeks! It is so good! Thanks for such an easy and good recipe!

  34. I don’t know why this appeared in my inbox today…lol Sounds delicious! My question is, can I use chunky peanut butter? I really have a thing for chunky peanut butter and since my mom always put nuts in her oh so chocolately fudge…make sense? Makes me drool thinking about it!

  35. This was the first time I made peanut butter fudge and this recipe was great. It turned out delicious and good. Thank you for posting the recipe

  36. I loved it thank you so much.

  37. I’ve been making it for years. I use half and half instead of milk and I cup of peanut butter. I butter the container instead of spray. it is always a huge hit.
