Easy Peanut Butter Fudge
This easy, creamy peanut butter fudge recipe is the BEST! Only 4 ingredients and 10 minutes of prep time; perfect for the busy holiday season.
Are you a fudge person? Like, a legit fudge person?
Our family doesn’t have a solid fudge tradition; it will show up on cookie trays occasionally, but I don’t have memories of my mom or grandma standing over pots of fudge and stirring, stirring, stirring until it was just right. So I’ve forged my own fudge path, and about 10 years ago, I – a massive peanut butter fanatic – realized that my repertoire was missing peanut butter fudge. I quickly set about righting that wrong.
I love peanut butter fudge because it is infinitely easier than chocolate fudge and, well, it’s peanut butter fudge. What’s not to love? No candy thermometers or intensive stirring required. All you need is butter, peanut butter, a pinch of salt, vanilla, powdered sugar and about 10 minutes. It is so easy, super forgiving, and makes the BEST fudge!
How to Make Easy Peanut Butter Fudge
This recipe is seriously SIMPLE, and don’t we all need a little something simple on our baking to-do list this season? In a word, YES. Let’s get to it!
First, you’re going to combine butter and peanut butter in a saucepan and bring to a boil. As soon as it hits that point, remove from the heat and stir in the salt, vanilla extract, and powdered sugar.
Spread it into an 8-inch square pan, cover with plastic wrap and refrigerate until it has set up, which only takes about an hour.
That’s it! Can you believe it? Seriously the easiest, most failsafe, DELICIOUS fudge on the planet.
Peanut Butter Fudge Recipe Notes
- You can make this in the microwave! Place the butter and peanut butter in a large microwavable bowl; cover with a paper towel and microwave on high for 2 minutes. Stir, microwave for 2 more minutes, then proceed with the rest of the recipe as written.
- If you don’t have an 8-inch square pan, you can use a 9-inch square pan, but the fudge will not be as high.
- The fudge can be stored in an airtight container or in a freezer ziploc bag for up to 3 months.
I think the best part about this fudge might be that it tastes just like the inside of buckeyes (another holiday staple!), except the fudge involves less steps and also less time. But no chocolate, so I guess it evens out!
If you need a peanut butter fudge recipe that does not require milk, that can be made in just 10 minutes and with ingredients you likely already have at home, look no further. This fudge takes little effort and will be a huge hit on all of those gorgeous cookie trays you’re going to build in a few weeks!

Definitely use 2 cups of powdered sugar instead of 4 . That’s way too much
I had never tried Peanut butter fudge until yesterday. My son’s beautiful girlfriend made it and I wanted to eat the whole pan! So glad to see it isn’t too hard and is quick to impress little kids who LOVE peanut butter! Making it tonight.
My nanny’s & great grandma’s
I think you had a typo. 4 cups confectioners sugar is WAY too thick. I think it should be 2.
I had to throw away. It was just a glob. It had way too much confection sugar. Maybe should have used 2 cups instead of 4.
This is just like the recipe I remember from my childhood and have been looking for. Lots of peanut butter so it really tastes like peanut butter. Most have a tablespoon or so of the stuff and just aren’t right. Thanks for putting this online just for me :D
The best. I used the stovetop method. Wouldn’t bother using another recipe from here on out- my go to! One thing I do think is extremely important in any baking but especially something like this that’s so rich and flavor- forward— USE GOOD BUTTER. It’s worth it for the best result. I used Keri gold for mine. Thanks!
Is powered sugar the same as confectioners sugar
I used to make Fantasy Fudge (on back of Marshmellow Creme jar) as a teenager w/ great success. As an adult, it never turns out. The only change I make is to used Guittards dark chocolate chips in place of Nestle’s semi sweet. It does not set and turns out like thicker frosting, so difficult for people to eat w/out getting messy. This year it was very soft, so I Googled and found out soft fudge is because of not getting it to 235-245 degrees w/ a candy thermometer. Growing up I never used a candy thermometer and had success, go figure…… Anyway I added some water per Googles recommendations and reheated for quite awhile to get it to pass the ice water ball test. What happened? It turned into a chocolate caramel which was so sticky I had to throw it out as I couldn’t even work with it to put it into small wax paper wraps. Ugh! What am I doing wrong? Do I have to go back to Nestle’s semi sweet morsels? Thanks.
I made this last night;, it is unbelievably good! I folded in some crushed up peanut butter cookies for a fun crunch.. I’ll be gifting this to everyone this month!
Wow this seems super easy to prepare!! A definite must try!
