Why I love this Easy Peanut Butter Fudge Recipe

This 5 Minute Peanut Butter Fudge is just what it sounds like – it takes just 5 minutes to cook, and it’s incredibly easy to make, too!

Unlike many fudge recipes, this recipe uses half and half instead of regular milk. This helps add to that rich flavor and creamy texture that I’ve come to love so much about peanut butter fudge!

I also make this Peanut Butter Fudge with Powdered Sugar instead of granulated sugar because you get a smoother fudge.

You don’t need any fancy equipment (other than a hand mixer) to make this deliciousfudge recipe. It’s a really easy recipe, and there’s no candy thermometer required!

All of the ingredients in this recipe are likely already in your refrigerator or pantry!

  • Creamy Peanut Butter – You’ll want to use creamy for best results; I prefer Jif Creamy.
  • Vanilla Extract – I’m a firm believer that you shouldn’t use imitation vanilla; pure vanilla extract (affiliate link) can add so much to a recipe!
  • 8×8-inch Baking Pan – I recommend using one with straight sides to keep everything cohesive, but any 8×8-inch pan will do.
  • Medium Saucepan – I personally like and recommend using a heavy non-stick pan for this recipe because it gets the job done and is a lot easier to clean.
  • Hand Mixer – I love my KitchenAid hand mixer (affiliate link) for quick recipes; my stand mixer is great but not always necessary, and this keeps things easy.

Substitutions for this Easy Homemade Peanut Butter Fudge

Since fudge is a candy, it’s actually very dependent upon the ingredients and process to turn out properly.

I do not recommend substituting peanut butter for another nut butter in this recipe because they can have very different consistencies (almond butter is much thicker and Nutella is much stickier for example). I also don’t recommend using all natural peanut butter. I personally use Jif Creamy for this recipe.

However, you can use salted butter instead of unsalted and you can also use granulated sugar instead of light brown sugar, if desired, just note that you will lose some of that caramelly flavor.

Prepare your pan and the powdered sugar before you start cooking so you can move quickly through the recipe for the best results.

How to make Easy Peanut Butter Fudge

Step 3: Pour the peanut butter mixture into a large bowl with the powdered sugar. Then, immediately whip them together with a hand mixer until smooth. Work fast because the fudge will want to start crusting.

Tips for making Peanut Butter Fudge with Powdered Sugar

1. Do NOT use all-natural peanut butter, as it has a higher amount of oil in it and can cause the fudge to separate. However, you can use crunchy peanut butter if you’d like.

2. Grease your baking pan with cooking spray, not butter. Or line it with parchment paper so you can easily remove the whole pan of fudge.

3. Using powdered sugar over granulated sugar yields a smoother, creamier fudge.

4. If your powdered sugar is lumpy, make sure to sift it or whisk the lumps out of it before adding it to the peanut butter mixture.

5. Make sure that once the mixture comes to a boil, you boil for 1 MINUTE 45 SECONDS ONLY, no more, no less. Like no-bake cookies, this timing is important to the final texture of the fudge, as we want to be able to control the water content of the mixture.

6. In follow up to the last tip, it’s possible that if you’re making this on a day when it’s raining or very humid, the water in the air can impact the final results of the fudge. Generally, it will have a harder time setting and may have a grainier texture.

7. You can mix the fudge mixture by hand when called for, but a hand mixer will help keep things quick and have a smoother end result.

8. Wait until the fudge has cooled to room temperature and fully set before slicing.

How long will Homemade Peanut Butter Fudge last?

Not long because you’ll likely eat it all 😉 but if you want to make it ahead or do have some leftovers, store them in an airtight container for up to 2 weeks in a cool area.

You have to control two temperatures to make successful fudge: the cooking temperature AND the temperature at which the mixture cools before stirring to make it crystallize. Confectionery experiments have shown that the ideal cooking temperature for fudge is around 114 to 115 °C (237 to 239 °F).
