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!
