Common Questions
How long do I let fudge sit?
This microwave peanut butter fudge recipe just requires about one hour in the fridge to harden before you serve it.
Can I add toppings to this 2 ingredient peanut butter fudge recipe?
You certainly could! For example, some sprinkles could add a really fun pop of color!
Can I make this fudge with any frosting?
I avoid making my peanut butter fudge recipe with either cream cheese or whipped frostings. The fudge just doesn’t taste the same with those kinds of canned icing.
You can pretty much use any brand of frosting though so feel free to use whatever one you like or have on hand!
How do I double this easy PB fudge recipe?
This recipe is super simple. It’s a 1-to-1 ratio of peanut butter and icing. So however much icing you want to use, just use that much peanut butter to balance it out.
If you want to simply double the recipe you’ll need to use 32 oz of peanut butter and 32 oz of icing.
Storage suggestions
The best way to keep fudge fresh for as long as possible is to keep it in an airtight container at room temperature. This will help to prevent the fudge from drying out before you’re finished with it.

Will this set if not refrigerated? I don’t care for cold fudge! Thanks!
Don’t want to rate it. Haven’t made it. So, if I must, I’ll give it one star.
I don’t know the answer to that. I always refrigerate because I like mine chilled. Thanks!
If you choose the sugar free Pillsbury frosting, this is 16 servings at 9 SmartPoints per serving
Does the fudge come out easily or do ou recommend using butter in bottom of container???
I have never buttered the pans. I have done it in glass and plastic and the fudges comes right out when cut. Thanks
My roommate made this with a coconut pecan frosting. Great taste but way too soft when set. It wasn’t whipped so not sure what went wrong. Will try other flavors.
I tried it with the coconut pecan icing too and it was a fail! I think there is a lot more oil in this frosting, so it won’t set. The peanut butter and vanilla is always a win. Thanks for stopping by!
Wow. I’m really in trouble now. I mean seriously, 2 ingredients? There’s no reason NOT to have this in my house at all times! Totally loving this!
I tried to make this fudge with sugar free frosting and peanut butter. It did not ever firm up. I guess it’s the sugar free frosting.
Sorry to hear that! I have never tried the sugar free.
I just made this with chocolate icing. I tried it before it fully hardened and I it tasted more like icing than peanut butter and chocolate. So microwaved more peanut butter and put it as a top layer.
. If it doesn’t turn out, it’s because I modified the recipe and will try the actual recipe. 🙂
Let me know how it turns out. I am not a fan of the chocolate icing. The flavor is just off for me. The white & peanut butter will always be my favorite. Thanks

I just encountered this recipe and made it with Peter Pan and Betty Crocker Triple Chocolate Fudge frosting. then I had an epiphany. If this works with peanut butter, why stop at just the most common nut butter. How would this turn out with cashew butter, or almond butter, or… wait for it… pistachio butter? I think this requires extensive research.
I just made this tonight and it is unbelievably good. I used natural and smooth peanut butter and buttercream frosting. I was concerned that the oil sitting on top of the peanut butter would prevent the fudge from setting so I poured it off (it amounted to less than a tablespoon). I was still concerned that it might not set, as this type is quite runny even at room temperature, so I added a tablespoon of unsalted butter to the peanut butter before heating it up and then stirred it thoroughly into it. This brand of natural peanut butter is also a bit grainy but once mixed and set it added a nice contrasting texture to the overall creaminess of the fudge. By far the best that I have ever made and I have made peanut butter fudge successfully with more complicated methods but don’t think I will bother after trying this one. Too easy and too good.
Awesome! Thanks for all the tips for those wanting different options.
I am thinking of making this with half Peanut Butter & Co. White Chocolate Wonderful peanut butter and half Dark Chocolate Dreams peanut butter along with frosting (undecided on the flavor, not sure which would taste best with the combination of the two flavors ). What do you think Michelle?
Peanut Butter happens to be an obsession of mine, I really can’t get enough of it. I love fudge, but I have never had Peanut Butter Fudge before. This is something I just gotta try! 🙂
I hope you enjoy it! Thanks for stopping by!
I made it with coconut pecan icing ….. Delicious
I wanted to make just a little bit of this so I used a 1/2 cup of each. It turned out great!
Great to know! I definitely need smaller batches so I don’t overeat it!
I just made this with caramel frosting and the peanut butter…in the fridge now… Looking forward to tasting it!!
May be a silly question, but do you put Plastic Wrap just to lay on top of the fudge?
I usually have mine in plastic or glass dish that has a seal or cover. Plastic wrap would be a great idea. I can’t wait to hear how it tastes. Thanks for stopping by!
This is a great and very easy fudge. However, I don’t understand about not using cream cheese icing.
I made this 2 times at Christmas to give for gifts and that is what I used. VERY GOOD
Good to know. Maybe the brand of frosting I used, made the difference. I had a hard time getting the creamed cheese or fluffy frosting to set correctly.
What size pb did u use with frosting?
Hi, it’s the 16 oz jar. I’ll update the recipe. Thank you!
I have a big jar of pb, what’s the ratio of cups for the pb amount?
I would use 2 tubs of frosting for one large jar of peanut butter.
Recipe says 1 tub. Well 2 tubs be to much?
You would have to double the peanut butter if you double the tubs of frosting. THANKS
Also, how well does this keep at room temperature? StillTasty.com suggests it should be kept refrigerated because of the frosting. I’m thinking about giving it as gifts this Christmas, but I’m not sure what the best way to store it, transport it, and give it is. If it melts too easily, I’m thinking about giving it frozen to keep it from spoiling during Christmas dinner. Does it freeze well?
I have frozen the fudge and when it thaws it has been fine. I would definitely refrigerate after it cools.
Has anyone ever tried doing this with sugar-free frosting (made with Splenda)?
I have never tried it with the sugar free frosting. If you try it please let me know how it turns out.
Yes I did use the sugar free icing and it works good too. I try to find the lowest grams of sugar in peanut butter. but I also used almond butter too. I also tried a bag of sugar free chocolate bits in it too. Excellent.
@Arnona Bogner,
Im make the icing peanut butter fudge can i also use chocalote chips
I would definitely try it with the chocolate chips.
