I’m not exaggerating when I say this Peanut Butter Fudge is one of the best fudges I’ve ever tasted. Rich, creamy, over-the-top fudge that is so easy to make, you might laugh.

Creamy Peanut Butter Fudge
My brother tasted this creamy fudge at my house years ago and called us the very next night for the recipe. He couldn’t stop thinking about it and needed to make it right away.
I gave him the recipe and he couldn’t believe this was all there is to it. With just four ingredients, this is one of the best peanut butter fudge recipes I’ve ever tasted, and it is also beyond simple to make.
I’ve been making this fudge recipe now for over 10 years now and it’s a solid keeper. Without fail, everyone who tastes it requests the recipe immediately.
Recipe for Peanut Butter Fudge
I was so excited to find Alton Brown’s recipe for Peanut Butter Fudge almost ten years ago and it’s become a family and friend favorite over the years.
It is an awesome way to impress someone with a gift that takes just minutes to put together. I can’t think of anyone who likes peanut butter and wouldn’t be excited to receive a box full of this during the holidays.
Put this recipe on your Christmas treat list now and skip the baking! It’s perfect to snack on while you’re wrapping gifts or for enjoying next to a crackling fireplace with the ones you love.

Peanut Butter Fudge
With all the attention we give chocolate fudge, I think the goodness of peanut butter fudge gets overlooked.
Don’t get me wrong, I love all kinds of chocolate fudge from Chocolate Almond Fudge to this Chocolate Covered Oreo Fudge and everything in between.
Peanut butter fudge brings images of childhood to mind, noses pressed up against confectionary cases, selecting the perfect square fudge to bring home.
The simple combination of sweet, creamy, and salty remains a favorite for kids and adults alike.

Easy Peanut Butter Fudge
The secret to making peanut butter fudge with the right consistency is in the powdered sugar. It dissolves into the fudge smoothly without any grittiness at all.
You can melt everything in the microwave or on the stove-top. However you make it, it’s dangerously easy. Your kids are likely to start requesting this fudge regularly.
Thankfully, this is a recipe that’s easy enough for them to learn how to make on their own! Plus, with no stovetop cooking required, you can teach them to make this fudge without fear of burn accidents.
This fudge is delicious just as is but is also a great canvas for adding mix-ins and toppings as well. I layer it with my 5 Minute Chocolate Fudge recipe to create Buckeye Fudge–a treat all of us found irresistible!

Peanut Butter Fudge Recipe
- Combine the peanut butter, butter, and vanilla in a glass bowl and melt in the microwave for 90 seconds.
- Stir to combine, it should come together very quickly and be smooth and creamy.
- Slowly add the powdered sugar a cup or so at a time. Stir to combine thoroughly.
- Grease an 8-9″ pan with butter or line with parchment. Transfer the fudge mixture to the pan and press into the pan.
- Chill for at least 4 hours before cutting. Store in an airtight container in the refrigerator.

PLEASE NOTE: The video for this recipe was made with a HALF recipe for this fudge. The recipe can easily be halved or doubled or multiplied however you like.
As pictured in the video, the fudge should be firm and almost crumbly when mixed together and pressed into the pan. It should not be liquid at all.
This simple four-ingredient recipe is made with real butter. The results can’t be guaranteed if you choose to substitute margarine or another butter alternative. The fudge might be greasy and might not even set up without the original ingredients.

How to Make Microwave Fudge
Kitchen Tip: I use these bowls and this spatula to make this recipe.
This recipe uses a microwave method for melting the ingredients together. While I’m not usually a fan of microwave cooking, nothing beats being able to melt baking ingredients to the perfect consistency in just moments.
It only takes 90 seconds of cook time to soften the peanut butter and butter to the right consistency, plus a few seconds of mixing. Add the powdered sugar to the other ingredients and mix well until the powdered sugar dissolves.

If you don’t happen to be a fan of the microwave, or don’t have one, you can easily melt the butter and peanut butter in a double boiler on the stove top.
It will just take a few minutes longer. Heat the mixture over low-medium heat and stir well to combine before adding the powdered sugar.
I love this fudge cut into 1-inch squares to make it easy to share. This fudge pairs beautifully with an ice-cold glass of milk, a hot cup of coffee or a mug of tea!

Easy Fudge Recipes
There are so many terrific fudge recipes that my family loves. The 5 Minute 5 Ingredient Chocolate Fudge I linked above has become everyone’s go-to recipe and it’s a favorite all year long.
I’ve used that basic recipe as the foundation for tons of different variations on chocolate fudge and it’s the one I find myself coming back to the most often.
White Chocolate Caramel Fudge has been a huge hit as well and I highly recommend you add it to your holiday baking list.
Give this Vanilla Walnut Fudge a try next time you’re in the mood for an easy fudge recipe that doesn’t use chocolate or peanut butter. Cranberry Macadamia Nut Fudge is another treat that’s perfect for the holiday season.
If you like this Creamy Peanut Butter Fudge, you might also enjoy this White Chocolate Peppermint Fudge from Real Housemoms.
I like to create gift bags or boxes with a few different kinds of fudge in them to give as gifts to friends and family throughout the holidays.
These fudge recipes are so easy to pull together that making two or three different kinds at once is a cinch. Fudge also makes a fantastic teacher or hostess gift!

Ok, Mary – you have gotten me with two more fudge recipes that I think I would love…I'm such a peanut butter lover and it is kind of funny how simple this recipe is. All the better!!
I'd rather cook things on top of the stove, how do the directions change?
Easy as can be. I'll add stove-top directions to the recipe. Thanks!
You can add 1/3 milk to this recipe and it makes an awesome cake icing.
I made peanut butter fudge last year and it was soooo good… this sounds even easier than the one I made…. guess I better try this one this year 🙂
Looks delicious Mary. As I got older, my sweet tooth waned significantly, but in my youth, I just loved peanut butter fudge, especially my grandmas.
You know I love this – how brilliant! It looks amazing and is perfect to share 🙂
Yummy, I love the tiny little bite sized pieces!
Hi Mary!! Can this go into the freezer? Thanks~~
Yes, you can freeze fudge, Billie.
Mine was crumbly…what did I di?
You possibly added to much sugar and made it too dry.
Try the Old Fashioned 3 Ingredient Peanut Butter Cookies best I ever had
Can you give me the recipe for the three ingredient for fudge
3 cups peanut butter chips
1 can condensed milk
1 teaspoon vanilla
Micro in dish for 1. 1/2 minute. Stir till chips melted. Add vanilla and nuts (opt) pour into lined sq. 8 X 8 dish , cool n frig till hard.
You can make fudge same way . And use white chips to make other flavors .
Absolutely the smoothest, creamiest best peanut butter fudge I have EVER tasted and I made it! I used the stove top method, total time maybe 10 minutes (including clean up) and it is sitting in the fridge right now! Thank you!
I made this today and it was delicious!!
I made this tonight and OMG it just melts in your mouth.
My daughter and I made these for her office (her first job!) cookie/candy exchange tomorrow. We wrapped each one in a sliver of wax paper and twisted the ends like toffee..they looked adorable! She made them by herself and was so pleased with the way they turned out. Thanks for sharing this super easy recipe, Mary.
Isn't this recipe the best? I have a similar one I make too! Peanut butter is my favorite! YUM!
Hi, I tried the stove-top directions but the powdered sugar wouldn't incorporate and the butter separated, what did I do wrong Mary?
That's very strange. Did you stir the butter and peanut butter together until it was creamy before taking it off the stove and adding the sugar?
It was my first time making fudge, I didn't take it off the stove when I added the sugar…
Oh my goodness, Sonya! That's MY fault. I didn't think to mention that in the stove-top version. (In the microwave one, the bowl is out of the microwave when you stir in in.) Darn it!! I'll correct it now. I'm so sorry about that!
Mary I made this but i doubled the ingredients. i let it sit in the fridge for six hours but it is still very soft. How do i get the fudge to become more firm ???
The recipe calls for a cup of butter that is 2 sticks and I find that to be to much I tried the recipe today and I plan to use I stick of butter next time
I did it also with two sticks and it does not work it’s way to buttery so I added more powdered sugar and had to soak up the butter oozing out of the fudge.
Hope it turns out ok
I agree two sticks is too much butter. I made it both ways and the one stick of butter in my opinion is much better.
It should be firm enough to slice by now, Nicole. Hopefully it firmed up overnight.
Just tried the peanut .butter fudge. It is so good!
This looks so good. Thank you for sharing.
This is great just the way it is-But have you thought about adding chopped pecan pieces. I would if I had teeth.LOL.
Family loved it thanks for another wonderful recipe!
This is so addictive. I made it the other night and in about 2 days I ate most of it.
I've got an easier one. A tub of vanilla cake frosting and a jar of peanut butter. Microwave 2 min and stir, pour in a greased square cake pan. Chill. It's the best I ever ate.
I have made this many times! Best and easiest ever!
