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. 

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

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.

    Can you make chocolate covered peanut butter fudge
    With this ?

  2. I added Butterfinger bits to this recipe. Delicious!

  3. Can I use sugar free frosting?

  4. Well I just made this with the vanilla frosting and the peanut butter. I have to say I’m very disappointed in the taste. I’ve made this before but I used the cream cheese frosting and it’s always been a hit and the flavor was great. But I was reading this recipe and I saw where it says “avoid using cream cheese frosting”. So I thought I’d give the vanilla a try. Well, never again.They have absolutely no taste , I’m afraid that there won’t be anyone eating these but me. Other than that they turned out great texture wise. Sorry for the negative comment.

    1. Sorry to hear this. I feel the same way about the cream cheese icing.I think it tastes horrible. I have never had anyone that i have served complain about the taste. It should taste more like peanut butter than anything. Thanks!

  5. Jeanne Stilwell says:

    I made mine with peanut butter and choc. fudge frosting, tasted just like a reeses ,

  6. This doesn’t make fudge. I tried it but still had to run to the store and grab a bag of white chocolate chips in order to get it to ‘set up’ Anyone who had this same problem this one added ingredient will fix the problem completely. 11 ounce bag of Hershey white chocolate morsels and done!

    1. Sorry to hear that. You must have overcooked. I have been making this exact recipe for 20+ years with no problems.

  7. Chris Reise says:

    I wish this page had a link to click that took me directly to the recipe instead of me having to scroll for a year just to find it. Especially when I discovered I tried this recipe before and it turned out like garbage.

    1. I guess you missed the print recipe button right at the top of the page. Oh, you were to busy trying to find things to complain about to see it…

  8. I made a double batch, it turned out perfect. So easy to make. Thank you for the recipe. Do you think if I added some peanut butter whiskey or cinnamon whiskey, it would turn out?

  9. Sharon I. Wells says:

    I ran into some peanut butter morsels mixed with chocolate morsels the other day. I thought I’d try them in my 3 ingredient quick fudge recipe. I bought 2 bags because I needed 3 cups of morsels and 1 can of sweetened condensed milk. I put the 3 cups of peanut butter and chocolate morsels in a microwaveable bowl and then put the can of sweetened condensed milk on the morsels. I did give it a brief stir to help get the milk divided more evenly on the morsels. Then I microwaved the mixture 15 seconds and took out and stirred to mix better. Then I put the mixture back into the microwave for 15 seconds and removed it and completely got it mixed thst time. Then I putvit back into the microwave for another 15 seconds to get it melted enough to pour into 9 by 9 inch pan lined with foil. Set in refrigerator overnight and cut into squares the next morning. Tasted more like reese’s peanut butter cups.
    Microwaving the chocolate morsels only 15 seconds at a time will help to keep from getting dry and hard pieces of chocolate

  10. Can I use a sugar free vanilla frosting?

    1. I have never tried it with sugar free frosting. If I had to guess I think it may not firm up. Let me know if you try it. THANKS!

  11. Has any tried putting chocolate chips on the top of fudge to let melt when done microwaving it?

    1. I have never added the chocolate on top, but I assume it would work after your fudge has hardened a bit. Melted chocolate on top may just sink into the mix. Let me know if it works. Thanks

  12. Pinky Felice says:

    I made this fudge and it’s delicious. I was wondering how long does it last in the fridge. I know it’s just frosting and peanut butter but is there a shelf life.

    1. After about a week it will start to dry out. I have frozen it with luck too. It never lasts more than a few days here though. Thanks!

  13. What if you don’t have a microwave oven? Can I do it on the stovetop? Thanks

    1. You could do it that way! You just need the ingredients to get softened enough to fully combine them!

  14. This sounds wonderful. I’ve lost 90 pounds on WW, but this sounds to dangerous to have around. Might make for holiday give away though. Thanks for the post.

  15. Traci lopez says:

    Can also use chocolate chips with crunchy peanut butter!!!

  16. Traci lopez says:

    I use chocolate chips and chocolate icing with nuts,Awesome!!!!

  17. michelle LaFayette says:

    I hate canned cream cheese frosting. I used per your recipe the reg vanilla. Then threw in a half brick of cream cheese, melted it up and worked really well. Sat it out after it hardened was GONE in an hour. I asked who who killed it, I’m assuming it was the son I never had, His name is notme. He tears up alot of stuff at my house. Thanks for a great easy recipe.

  18. Very smooth and easy to make but I didn’t think it set-up like a traditional fudge does. I don’t think it would hold up outside of the refrigerator (like on a platter).

    1. I’ve never had a problem with it setting up and holding up just fine on a plate or in a gift can.

    Can i make these into fudge balls?
