  5. The recipes I saw said 9×13. This is way too big and ended up with very thin fudge. Fudge should be chunkier. I wish I had used a square pan!

  6. I reuse the empty frosting tubs by cutting a strip of gift wrap and wrap it around the tub. Fill it with fudge and replace the lid stick a bow on top and you have a perfect gift for teacher or neighbors.

    1. Yes, it does! My friend just used this recipe for a potluck at work and I brought some home with me unrefrigerated and hours later, it’s still set and tastes AWESOME.

    Spousal Unit loves PB fudge. I looked around serveral months ago found regular type recipe and THIS one! I loved the idea. Quick and easy. I’ll be darn, he loved this one better than regular fudge! I’m making things for Easter,, he asked for That one fudge. I looked thought my recipes folder couldn’t find it. Googled. Thank goodness! Found it.. Why I am writing… I realized, I just bought a standard can of icing.. However much that measured out. Again.. There were no complaints. 🙂 thanks for sharing this.

  28. I’m trying to make this fudge I feel stupid but how many cups would it be for a pound of frosting.

  31. This can definitely be made with you’re own homemade icing. It’s not that hard… I think if you’re super busy then the can is a good idea, it’s ok now an then. All families need’s are different!!
    Thank you for posting!

    This was so easy and so good! I made it three times over the holidays. I made it with chocolate frosting too, but prefer the vanilla. I can’t believe how great it turns out! Thanks for sharing.

  34. We ice our chocolate cake with this recipe (use a little less pb) and everyone thinks it homemade icing. It’s so good and fudgey.

  36. I just made this and can tell it will be creamy and delicious, I make chocolate fudge often and would like to try a chocolate version of this without peanut butter, any suggestions ? Thanks

  37. Susan, I am a health freak when it comes to food. People think I’m nuts for not owning a microwave. So I do agree with you in terms of the stated ingredients. However, that doesn’t mean that substitutions can’t be made. I make them ALL the time (natural for processed/artificial, etc.).
    I think this is a great recipe. Especially in today’s world when so many people have very little time on their hands. It is SO easy to make this with natural ingredients. Fudge being made from scratch doesn’t mean it’s anymore \wholesome\ than this recipe.
    As I was reading it I was thinking, \substitue w all natural peanut butter (the kind that needs sturred), and simply make own icing from all natural ingreds. If anything, making it this way will give many more flavor options.
    I substitute ingredients for natural ALL the time. Don’t let a recipe’s ingredients stop you from making it if it’s proven to be wonderful and easy to make.

  42. To me, food is supposed to be wholesome and nourishing, even if it’s a sugary treat. Canned frosting is full of chemicals that are not food! Making fudge from scratch takes a bit longer, but it’s worth it.

  44. I would like to caution you against heating either one of these products in the plastic containers in which they are purchased. Read about BPAs for yourself. Just Google!

    I made this over the weekend and was phenominal! I made it with the Pillsbury chocolate fudge frosting. What was even better after I cut it I froze it so I wouldn’t have easy access to it…however it was amazing frozen it was exactly like a peanut butter cup. One a side note, Jif does not make a 16.3 oz, I looked at the store and did not find one, so I went to the website and they make a 12 or 18 oz so I used the 18 oz. Thanks for the recipe!

    This recipe can also be made easier by leaving the peanut butter and the frosting in their original package, microwaving each for one minute, and then pouring both into a mixing bowl. By microwaving them in their original package you eliminate digging the cold product out. The heated product simply pours out. I also use cream cheese frosting instead of vanilla. Just peel the lid off and microwave, its that easy! Mix together in mixing bowl, pour into 13×9 pan, and refrigerate till firm.
    This is the best and easiest peanut butter fudge recipe I’ve ever seen!!

  50. Let me add another one….heat 1 tub frosting until melted thoroughly, add one bag chips. Stir to melt, and pour into a 9×9 square pan. Any flavor frosting, and flavor chips. Sets perfectly every time, sprinkle with nuts (or sprinkles) if you want!

    BIG hit for teachers gifts ! I got a 2 pack of holiday square plastic containers at the dollar store. I made 1 batch vanilla frosting with peanut butter and a 2nd batch chocolate frosting with chunky peanut butter frosting….cut into squares and layered in the container. Very easy and o so good! Also, my sister did cream cheese frosting with the peanut butter. There is so many combinations its mind boggling. But, they all work !

  57. This is in regards to the comment from Kati Mora in regards to making the fudge, I belive the recipe called for chocolate or vanilla prepared frosting and not pudding, or this maybe a different recipe she is commenting on. Just thought I would give may comment

    1. Thanks for keeping an eye out Pat! Definitely meant to say frosting in my comment – not pudding. I don’t think pudding would work quite as well in the fudge making process. 🙂

  59. I was just thinking about PB fudge over the weekend as I made regular fudge. Thanks for the easy recipe! Now I just have to find premade frosting. 🙁

  60. I love having fudge on occasion – especially when there is peanut butter involved. And I’m glad you mentioned using chocolate pudding instead of vanilla – chocolate + peanut butter is definitely one of my favorite flavor combinations.
