How to make 2 Ingredient Peanut Butter Fudge
Unlike most quick & easy versions of fudge, like my Cookies 'n Cream White Chocolate Fudge, this easy recipe doesn't use marshmallows or marshmallow creme to thicken it.
- Melt peanut butter and frosting together in the microwave and stir until smooth.
- Pour the fudge mixture in to the pan lined with parchment paper or aluminum foil for easy removal.
- Refrigerate until firm. Cut into squares.
Hint: Line the pan with parchment paper, wax paper, or aluminum foil to easily lift out the chilled fudge. This makes it so much easier to cut into even squares and prevents a sharp knife from cutting into your pan.
Can I make this fudge without a microwave?
Yes. You can still make this fudge if you don't have a microwave. Stir the peanut butter and frosting together in a medium-size saucepan. Heat over medium-low heat, stirring constantly, until smooth and both melt.
Substitutions & Variations
There are so many different flavors of fudge to make with this basic 2-ingredient fudge recipe! These are just a few I thought of in minutes.
- Chunky Peanut Butter Fudge- Trade out the creamy peanut butter for chunky peanut butter.
- Chocolate-Peanut Butter- Use chocolate frosting instead of vanilla.
- Chocolate-Peanut Butter Swirl- Use chocolate frosting with peanut butter and dollop extra peanut butter on top immediately after pouring into the pan. Drag the tip of a table knife through the dollops to create swirls.
- Candy Bar Peanut Butter- Chop your favorite candy bar such as Butterfinger, Hershey milk chocolate bar, or Reese's cups and press them into the top of the fudge after pouring.
- Cookie Fudge- Coarsely crumble chocolate chip cookies and stir in before pouring and/or press into the top of the fudge.
- Birthday Cake- I don't know about you, but I'd love my birthday cake flavor to be peanut butter! So, why not stir in a tablespoon or two of sprinkles.
- Chocolate Covered Buckeye Squares- At my Holiday Cooking Show, someone suggested coating pieces of fudge in chocolate to resemble Reece's peanut butter cups.
I tried to figure out a way to make a PB & J version of this fudge but it was a little messy. Let me know if you solve this dilemma!
Not all tub frostings are the same! I tested this recipe with many brands and I found the best ones for this recipe were Betty Crocker and Aldi store brand. Other brands had a higher water content which didn't provide a smooth texture.
Also, do not use "whipped" frosting. Extra air has been incorporated into the frosting and will also give an undesirable texture.
- Microwave or saucepan
- Spatula. I prefer this one to reach to the bottom of the peanut butter jar.
- Parchment paper (optional)
Does peanut butter fudge need to be stored in the refrigerator?
While this fudge needs to chill in the refrigerator at least 1 hour to set up initially, it does not have to be refrigerated for storage. It stays firm on the counter.
Does 2-Ingredient Peanut Butter Fudge make good holiday gifts?
Absolutely! Not just for holidays, but year round food gifts. I make this easy sweet treat recipe for my husbands clients all the time. They fit perfectly in gift boxes, stack nicely in gift bags and looks impressive as a slab of fudge wrapped in plastic wrap and placed in a gift bag.

I'm so glad you are going to try it! Yes, it's crazy easy and no one will know it took you 5 minutes to make!
Hi there, living in South Africa our ingredients are not the same, what substitute can I use for the frosting..
Hello from around the world! So happy you landed on my site. The crazy, magical way this 2 ingredient recipe works is the combination of the two working together. While I don't have a substitution for these two ingredients to work so easily together, I do have another simple easy fudge recipe that still doesn't require a candy thermometer. It's Cookies n Cream White Chocolate Fudge. It uses sweetened condensed milk and marshmallows to thicken the fudge. You can leave out the cookies if you just want white chocolate fudge. Here's the direct link.https://gritsandgouda.com/cookies-n-cream-fudge-2/ I hope this helps!
