I’d like to make a case for eating peanut butter fudge year-round. It takes minutes to make, there’s no need for an oven, and well, doesn’t everyone have a jar or two of peanut butter in their pantry?

Why is Peanut Butter Fudge the Best?

Peanut butter fudge is my favorite fudge flavor of all, which says a lot coming from a girl who loves her chocolate. Now, if you offered me a chocolate candy bar or a spoonful of peanut butter, I’d take you up on the chocolate. But if you offered me chocolate fudge or peanut butter fudge? Completely different story. (I feel like I need to thank you for offering me fudge in this hypothetical scenario, heh).

Not to smack-talk chocolate fudge (especially considering I have an excellent Chocolate Fudge recipe), but peanut butter fudge has more depth, it’s not as one-note. You will not tire of peanut butter fudge. This fudge will have you wanting more. It is addicting. I make no apologies, you’ve been warned.

Easy Peanut Butter Fudge

The best thing about this peanut butter fudge? How delicious it is. The second best thing about it? How easy it is to make.

I’m convinced that the instant pot is the simplest way to make homemade fudge. There’s no need for a candy thermometer. You don’t have to stand by the stove or by the microwave and stir. You just pour some ingredients into a pot, pressure cook, and mix.

While testing this recipe, I made several batches and played around with different ratios, and you know what? The peanut butter fudge was good every time, but this recipe, as written, is the best. It’s the right amount of creamy and peanut buttery and (white) chocolatey.

How to make Peanut Butter Fudge in an Instant Pot:

First, we make sugar syrup: mix water and sugar and pressure cook. Easy!

Add butter, peanut butter, white chocolate chips, and vanilla extract. Mix.

Slice and enjoy!

What Size Instant Pot?

All of the recipes on my website are tested using a 6 quart instant pot – I have not tested this recipe in a different sized pot as the surface area is different and will affect the temperature of the sugar syrup.

Can I Make this in an 8-Quart?

As I mentioned above, I have only tested this recipe in a 6 quart. However, some readers have experimented with this recipe and have reported that they’ve been able to successfully make this fudge in an 8 quart by doubling the recipe – you can read through the comments at the end of my post to see what readers have to say.

I’ve made this twice and it has worked perfectly both times. I have an 8-qt pressure cooker, so I just double the recipe and it works just fine. Not only is it easier than making it on the stovetop, it is sooo yummy. This is my new favorite peanut butter fudge recipe.

“Hi Ashley I made this peanut butter fudge last night. I subbed the white chocolate chips for Ghiraradelli white chocolate melting wafers. I have an 8 quart instant pot and doubled the recipe. It came so creamy and delicious. Thank you for such a great recipe!”


How to Store Peanut Butter Fudge:

I store fudge in an air-tight container in the fridge for 2-3 weeks, or in the freezer for a few months.

This fudge stores well in the freezer. In unrelated news, I have been spending a lot of time standing by the freezer. 😉

    Alright Ashley. You’ve crossed over to evil with this recipe. I’ve only had my instapot for about a week now and only because one day I ventured down to the kitchen and the wife had bought and brought it home So far, I’ve made two of your dinner recipes and both were excellent keepers. The fudge is dangerous because it is so easy and so good. Not quite sure I operated the instapot correctly but the end product was certainly delicious. Thanks again. Your recipes are 3 for 3 for excellence and keepers all.

    I stumbled upon this recipe last you (THANK GOODNESS). By far the best peanut butter fudge I’ve ever made. This year made regular with white chocolate chips but also made a couple batches with milk chocolate and it’s equally as good….decisions decisions. Hope it lasts long enough to make it to the neighbors.

    I doubled the batch in my 6 qt IP and it’s deliicous! Although, the color of my peanut butter fudge was light-colored and not the color of the recipe. How do you get the golden color?

    • Ashley - My Heart Beets says

      Debi, that’s so great to hear! Thanks for letting me know how much you liked this recipe 🙂 As for the color, is it significantly lighter? Maybe it has to do with how dark the peanut butter is? I’m not sure, hopefully another reader can chime in.
