Do you need a quick and easy dessert this holiday season? Of course you do! That’s why you’re here! And we have this creamy and dreamy Peanut Butter Fudge that is the answer to your easy dessert woes. We’ve all had chocolate fudge, so take a walk on the wild side and bust out some peanut butter. It’ll be the best decision you’ve made all day. And fair warning: You may need a second batch because this will disappear fast!

Only Four Ingredients!

Yes, oh yes this is the easiest recipe to make because there are only four ingredients. They’re common, household ingredients that you already have on hand, pinky promise. Let’s take a look at what they are:

  • Salted Butter – We love using salted butter, but if you have unsalted, don’t worry. You can still use it and add a pinch of salt at the end!
  • Peanut Butter – Any brand of peanut butter will work, just make sure it’s not natural. Natural peanut butter won’t mix or melt well in this recipe. We also recommend using smooth peanut butter, but if you’d like your fudge with a little texture, use crunchy peanut butter.
  • Powdered Sugar – You definitely need to make your fudge sweet, and powdered sugar is the way to do it! It also helps to build the structure of the fudge.
  • Vanilla Extract – A splash of vanilla is essential in any sweet treat. It brings all the flavors together in perfect harmony.

A Microwave Fudge Recipe

Not only are minimal ingredients required, but this fudge can be made in the microwave. Yes, you read that right… THE MICROWAVE. No official cooking required. Just make sure that you have a microwavable bowl on hand, and that you melt the ingredients in 30 second increments and stir in between. This will ensure a smooth, velvety texture to the fudge.

How to Make Peanut Butter Fudge

Making this fudge is incredibly easy… You could do it with one hand behind your back! We don’t really recommend doing that, but it could be done. Ha! Let’s see how to make this fudge, shall we?


  1. Line a 9×9 baking dish with parchment paper or wax paper and grease lightly. Set aside.
  2. In a large bowl, melt peanut butter and butter together in the microwave until smooth.
  3. Stir in vanilla and powdered sugar until thick and smooth. Pour mixture into prepared dish, smooth the top and cool in the fridge until firm.
  4. Cut into squares and serve.
  5. Store in an airtight container. Left at room temperature, fudge is good for two weeks. Refrigerate to extend it another week.

That’s it!

How to Freeze Fudge

If you’re looking to make this peanut butter fudge recipe ahead of time, you can certainly freeze it!

Freeze. Wrap in plastic wrap then store in a freezer bag for up to two months! Freeze the fudge in a block and then cut in squares after thawing.

Bring to Room Temperature. Simply let it thaw on the counter for a couple of hours or until soft enough to cut into squares.
