Whether you’re making it for the holiday season or any other time of year, you’ll love how easy it is to make this creamy sweet treat!

It’s such an easy microwave peanut butter fudge recipe you’ll find yourself making it often. And that’s okay. There’s nothing wrong with treating yourself to some yumminess when you want it.

Quick and Easy Peanut Butter Fudge

You have a wide variety of choices of how you want to make your peanut butter fudge. I’ve made several of them, and I can honestly say this way blew my mind.

Even the easiest fudge from my recipe box had at least 3 ingredients … until now.

I have to admit that my expectations were low when I first decided to give this recipe a try. Then I tasted it.

Whoa. I can honestly say this is one of my favorites—and that’s based on the flavor.

The fact that it’s so easy and has so few ingredients is a bonus.

A friend of mine told me about this recipe and said I needed to share it on my blog. She also mentioned that this recipe has been circulating for decades.

I wonder why I never knew about it before.

Although I followed the basic recipe she told me, I adjusted a few of the steps. That’s because I thought it should be easier.

And it was. It turned out great the first time I made it—something that doesn’t always happen.

2-Ingredient Peanut Butter Fudge Ingredients

As the name implies, you only need 2 ingredients—a can of ready-made vanilla frosting and 2 cups of peanut butter.

I used creamy peanut butter, but I’m sure the crunchy version would be delicious … just crunchier. Obviously.

I wanted more of a melt-in-your-mouth texture, and that’s exactly what I got.

For exact measurements of each ingredient and full directions, go to the recipe card at the bottom of the page. You can even print out the card by using the “print” button.

If you want to try different flavors, go for it. I’ve heard that chocolate frosting mixed with the peanut butter is delicious.

I might try that next. But in the meantime, I’m going to savor what I have left of this one.

How to Make 2-Ingredient Peanut Butter Fudge

Since this is such an easy fudge to make, you don’t need much equipment.

Basically all you need are a 9” x 9” pan, a microwave-safe bowl, a big stirring spoon, and a microwave.

If you want thicker fudge, use a smaller pan. Keep in mind that the thicker the fudge the longer it takes to set—but only by an hour or so.

First, you can either line a pan with foil or grease the bottom of the pan. I chose to use foil because that makes cleanup so much easier.

Secondly, combine the peanut butter and frosting in your mixing bowl.

Resist the urge to stir it because it will be extremely difficult at this point.

Frosting and peanut butter in a bowl

Stick the bowl in the microwave for 60 seconds. Now stir the contents. It’s had time to melt enough to stir without too much trouble.

Keep stirring until the mixture is smooth and creamy. Make sure it’s well mixed, or the texture will be inconsistent.

Once it’s well mixed, put it back in the microwave for another 60 seconds. Take it out and stir it again.

Next, pour the mixture into the pan. Make sure to scrape all of the goodness out of the bowl because you don’t want to waste a single drop of it.

Final Steps

Put the pan in the refrigerator in a level spot if you want consistency in the thickness of the fudge. Years ago, I had a tilted fudge pan, leaving one side thick and the other side thin.

Now resist the urge to “check on it.” The fudge will be just fine if you leave it alone for a couple of hours.

If you struggle with the temptation, find something else to do, like a long walk through the neighborhood or a bike ride. Then you’ll be able to justify having an extra piece once it’s ready.

Finally, remove the pan of fudge from the fridge.

If you used foil to line the pan, you can lift it out by grasping the edges of the foil. That also makes it easier to cut.

You can cut the fudge into squares or rectangles as big or as small as you want.

I like smaller squares because then I can reach for “just one more piece” without feeling too guilty. Yeah, I know that’s flawed thinking.

Can this be frozen, to keep some for later?


Tuesday 3rd of August 2021

Hi Jaci. Yes, you can freeze it. Just make sure to let it cool first. Cut it into the size pieces you want and wrap them in plastic wrap or aluminum foil. Then put them in an airtight container before freezing. I think it should good for up to a couple of months.

Thank you, Martha! It is wonderful because it's delicious and easy to make!

Is there any way this recipe will make vanilla fudge?


Sunday 11th of October 2020

Hi Mary. I don't know how you can do that because part of the texture of the fudge comes from the peanut butter. I make a white chocolate fudge that might work for you. Here's a link:

Hi I just wondered should this be kept in fridge? Will it get too soft & pieces lose shape if left out of fridge? Thanks


Saturday 26th of September 2020

Hi Sandy. This depends on the temperature of your house. I live in the South, so I keep it in the fridge. If it doesn't get too warm in your house, it's probably fine to leave it out.
