First, you’ll lightly spray an 8×8 dish with non-stick cooking spray.

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.

  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. this was good…however, theres a recipe using “Kraft marshmallow cream that is 10 times better!
    Lots more “creamy……instead of Milk, there is evaporated milk used instead.
    You can find this recipe on the back of the “Kraft Jet Puffed Marshmallow cream jar…This can “easily be used with “Semi sweet chocolate OR substitute “crunchy peanut butter(or plain)

    Not overly sugary like most fudge recipes and so much more “creamier”.
    I live in Michigan where people travel “miles ” for “Mackinaw Island Fudge”…After trying “this Fantasy fudge using Marshmallow creme…I have NEVER bought fudge.All my family and friends “request this for Christmas…Try it!

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