Why You’ll Love This Easy Peanut Butter Fudge Recipe
- Extra peanut buttery flavor!
- Creamy and soft
- Only 4 ingredients
- SO easy, 10-minute microwave recipe
- Beloved by family and friends for YEARS and YEARS!
Ingredients
- Smooth peanut butter – regular, smooth peanut butter is the best option for making this fudge! Stay away from natural peanut butter.
- Confectioner’s sugar – confectioner’s sugar (AKA powdered sugar) is the base for fudge! I use less confectioner’s sugar than most peanut butter fudge recipes. You end up with a rich peanut buttery taste and soft, creamy fudge.
- Salted butter – I use salted butter so you don’t need to add salt too. You can add in ½ teaspoon salt if you’re using unsalted butter.
- Vanilla extract – vanilla extract adds flavor.

My Pro Tip
Tips for Making the BEST Easy Peanut Butter Fudge
- Stay away from natural peanut butter.
- If you don’t have a sifter, you can simple add in unsifted sugar and work the lumps out by heating the mixture according to the steps above.
- If you’d like to make a pretty design on top of your fudge, refrigerate the prepared pan of fudge for a few minutes until it just starts to set. Then use a spatula to make a pretty swirl design, and place your fudge back in the fridge to finish setting!
- Run a knife under hot water to slice peanut butter fudge with ease.
- If you like your peanut butter fudge soft, enjoy at room temperature. If you like your peanut butter fudge more dense, enjoy chilled.
FAQs

Hi there, can I add toasted pecans to fudge without worrying that it wonโt harden? Thanks๐ค
Hi Nancy,
Yes, that shouldnโt be a problem! ๐

I made fudge for the first time! Thank you. Fudge I am given is always too sweet and not peanut buttery enough. This was sooo perfect. I am making another batch tomorrow.

I love this recipe, it’s easy, simple and delicious. I gave my neighbors some and now at least once a week I have one or more of my neighbors come to me with peanut butter, powder sugar and the other ingredients and ask if I can make my delicious peanut butter fudge. It’s a big hit in my neighborhood, I don’t mind making it for them cuz I get more fudge that way. Delicious Delicious Delicious can’t wait to make it at Christmas time and give it out as gifts to friends and family
Hi Cindy,
Your review made me so happy! Thanks so much for letting me know. Merry Christmas!
Grace
So easy to make! I have a question! Instead of adding melted chocolate chips could I just use cocoa powder and if yes, how much?
Hi Lydia,
Hmmm, I’ve never thought of that! I’d imagine you can use cocoa powder! Sprinkle the cocoa powder over the surface of the peanut butter fudge. Use a toothpick, skewer, or knife to create swirls by gently dragging it through the cocoa powder and peanut butter fudge mixture. This will create a marbled effect. I’d start with 1/4 cup and if you want more, keep increasing a tablespoon at a time.
I hope this helps!
Grace
Thank you! I won’t do the marble effect but I will stir it in that way the taste of the cocoa powder isn’t bitter just sitting on top. I’ll let you know how it turns out! Thanks for your recommendation! Merry Christmas! ๐
Mixed in, I warn you that the texture of the fudge might change! I just don’t want to lead you on and then have the fudge not set correctly. If you try it, let me know how it goes! Merry Christmas to you as well ๐
