2 Ingredient Peanut Butter Fudge

2 Ingredient Peanut Butter Fudge is a long time favorite in our house! Over the years I have made this fudge for bake sales, family gatherings and just to have around the house for a special treat. I avoid making the recipe with cream cheese and whipped frosting. The fudge just doesn’t taste the same with those types of canned icings. I have used chocolate icing too, but I really prefer the plain old vanilla. I have been told by others that the cream cheese frosting tastes just fine to them, so it’s probably my dislike for cream cheese in general that makes me think the taste is odd.

2 Ingredient Peanut Butter Fudge

Feel free to experiment with different flavors and tastes. Last fall we tried the maple bacon frosting with peanut butter and it was definitely a favorite around the dessert table.

2 ingredient peanut butter fudge is a family favorite.

This fudge is a perfect Christmas or any time of the year gift. I look forward to sharing it with the mail lady, Sunday School teachers, co-workers and anyone who drops in for a visit. Christmas is all about giving. Even if you don’t have a lot of money to buy for others a special homemade treat is sure to warm someone’s heart.

 Be sure to pin 2 Ingredient Peanut Butter Fudge above or print it below:

2 Ingredient peanut butter fudge only takes 2 minutes to make.

When I mix up this treat, I always have a rubber spatula close by. You’d be surprised at how many extra servings you can scrape from a peanut butter jar or icing container with just a few swopes of a spatula. I’d have to say that the rubber spatula is one kitchen gadget I could not live without.

My fudge is normally made in a 8 x 8 glass pan. I prefer one with a lid for easy storage and transport. I keep my fudge in the refrigerator. The glass pan lets me see what’s inside and is a perfect size for a nice thick piece of fudge.

    I love this recipe! I make it all the time! I have found that the fudge has a much silkier texture if you melt the peanut butter and icing separately, and then mix the two together. I line my glass pan with foil and then just pop out the whole thing to cut into pieces. Thanks for sharing!

            If you microwave too long it will not set correctly. Was it the whipped icing? That will make a difference. Vanilla is my stand by. Sorry it didn’t set. The only thing I can figure out is the frosting might have changed, since companies always update it. Sounds like you have a good ice cream topping if it didn’t get hard. Thanks

      How many oz. of frosting do you use? It seems the tubs are smaller than they used to be and it may not be enough for that much peanut butter.

      I’ve always heard that organic peanut butter had a lot more oils than store bought this why it’s not best to use unless u add powder sugar

    Hey i love your blog! The thing is… I don’t have a microwave (I know it sounds crazy) but, could I just heat the peanut butter and vanilla icing up on the stove top in a sauce pan?

      I am sure a stove top would work. Heat just enough to stir together thoroughly. Be careful not to burn. Good luck!

      i’d be careful with direct heat, maybe try putting the ingredients in a bowl on top of a sauce pan of boiling water – like you would for melting chocolate. (Don’t let the water touch the bowl though)

    i sure wish I had come across your recipe yesterday… 🙁 I saw the same recipe on facebook and thought it would be something quick and easy I could do while the rest of the food was cooking… Only problem is, there was no mention of “not” using whipped or sour cream frosting…. Guess what I grabbed because there was no vanilla frosting left on the shelf? Sigh!!

      Could try to add some melted chocolate pieces into the mixture. Use white or peanut butter chips if making the peanut butter fudge. Chocolate chips for peanut butter and chocolate. half to 3/4 cup of chips could help set the fudge…. You would have to experiment.

        the only suggestion i have about using Nutella is to microwave it for less time. when we took it out of the microwave after the second minute there was an oily liquid separating. it took lots of stirring to get it mixed back it, not certain we entirely succeeded. it is still delicious.

    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 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.

        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?

    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 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. 🙂
