This simple method for making homemade fudge takes only 15 minutes to throw together, and it calls for just five basic ingredients. This fudge is smooth, creamy and sweet, and it’s packed with peanut butter flavor. Because of its high butter content, fudge is best stored in the refrigerator, and it’s easiest to cut into squares after it’s been thoroughly chilled. The fudge can be served directly from the fridge, but for optimal creaminess, let it sit at room temperature for a half hour. While this recipe calls for an 8-inch-square pan, a 9-inch-square pan or rectangular pan with a similar volume works, too.

Easy Peanut Butter Fudge Recipe (2)

Preparation

  1. Step

    1

    Grease an 8-inch-square pan with butter. Line the bottom with parchment paper, then grease the paper.

  2. Step

    2

    In a medium saucepan, combine the butter and peanut butter. Cook over medium-low heat, stirring often, until melted and smooth, 3 to 4 minutes. Do not let the mixture come to a simmer. Off the heat, stir in the vanilla and salt.

  3. Step

    3

    Scrape the peanut butter mixture into a large bowl. Gradually add the confectioners’ sugar a few spoonfuls at a time, whisking until the sugar is fully incorporated after each addition. After all the sugar has been added, mix well with a rubber spatula until smooth.

  4. Step

    4

    Transfer the mixture to the prepared pan and smooth the top. Cover with plastic wrap, pressing the plastic to the surface of the fudge. Chill for at least 2 hours, until set. Use a knife to cut the fudge away from the pan, then lift the parchment paper to remove it. Cut into 1-inch squares. Store fudge, covered, in the refrigerator for up to 5 days or freeze for up to 2 months (see Tip).

Tip

  • To freeze, wrap individual pieces with parchment or wax paper. Wrap again with aluminum foil, then store in a resealable freezer bag. (You can also wrap the whole sheet of fudge before slicing, wrapping as you would with individual pieces.) Defrost fudge overnight in the refrigerator.

50 servings in 8x8 pan. Lol.

Perfect peanut butter fudge recipe! Yes, it calls for “not natural” pb but let’s keep it in perspective. You’re making fudge…with a cup of butter and 3 cups of confectioners sugar. The PB is the least of your concerns.

Lisa

When recipes like this call for smooth peanut butter, not natural, they mean Jif or Skippy or even Justin's. Something that is smooth and does not separate (no stir). And, NYT does have a peanut butter/marshmallow recipe: https://cooking.nytimes.com/recipes/2815-fudge. If that doesn't suit, the Jif recipe for same is pretty great: https://www.jif.com/peanut-butter/recipes/peanut-butter-fudge.

I really hate the gunk that goes into “not natural” peanut butter. Does anyone have advice for substituting natural peanut butter (just peanuts and salt) into this recipe?

Nuts to you!

I added chopped pecans, about a 1/2 C or so at the end. Forgot the vanilla. Melt-in-your-mouth delicious.

Lynn

Would appreciate peanut butter brand suggestions. That’s difficult, legally, I suppose. Some are called “peanut butter spreads”. I wish NYT would publish a really good marshmallow peanut butter fudge recipe. Lost mine.

DKW

An 8x8 pan would yield 64 one-inch squares. 9" pan would, of course, give us 81 shallower pieces.

Ghee is butter, a dairy product.

Awful

I thought this recipe was disgusting. You might as well eat a cold stick of butter dipped in confectioners sugar with PB2. I couldn’t get it out of the pan without it crumbling into a million pieces. Complete waste of ingredients and time as it went straight into the bin after I tasted it.

Drew Right

Mine turned out grainy. Could this be a result of not sifting sugar?

Gale

I love peanut butter and eat it by the spoonful from Trader Joe's "green label" (creamy unsalted) jar. However, I bought some JIF for our puppy and he doesn't like peanut butter. SHOCK, but since I had some "not natural" it was easy to combine with the other 4 ingredients to make this delicious, EASY fudge. I cut my pieces larger so there were not 50, but 25 pieces- not too large and not too small. I'll be making this again... and riding more miles!

Colorado Cook

Dad, Jillian and I liked this. Tastes like the inside of a Buckeye. A bit too buttery for me but not sure if the recipe works with reduced butter amounts. Would make again for gifts or parties.

terry

I used 1/2 creamy and 1/2 chunky peanut butter (Skippy). Very tasty and easy to make. Store in fridge for firmer texture in zip lock bag.

Christine

You can make this a little bit better if you add a little bit of melted chocolate on the top of it. It makes it taste like a Reese’s Cup.

Karen B

I had a hard time breaking up all the tiny lumps of conf sugar, and toward the end I applied my hand mixer, which quickly did the job. The fudge turned out well and left me wondering why the whole mixing process couldn’t have been left to the mixer.

Sophia

This was legitimately so good and super easy. I know the reviews seem really conflicting but I have no idea why people were saying it was bad. The texture was almost perfect and taste was amazing!

Drew

Mine crumbled as well.

David Holmes

So the peanut butter is not supposed to be natural? What is "unnatural" peanut butter?"

Heather

hom*ogenized / i.e. that which is smooth at room temperature and doesn't need to be stirred. Natural peanut butter is made of just peanuts and salt generally, and doesn't work well for many baking recipes.

Ann

too sweet

Dale (she/her)

Whoa - I closed my exercise ring whisking in all the powdered sugar. LOL. I would plan for more than 15 minutes for this recipe to get it all folded in. The pre-fridge tasting tells me this is going to be divine.

Angelica

From our Thanksgiving crowd not one person ate more than one because they taste just like frozen butter, the peanut does not come through. Plus, they don't look appealing.

Loz

It's not true fudge but totally delicious and much easier it make. I used crunchy Skippy peanut butter and it worked well

FAQs

What is the secret to good fudge? ›

Tips for Making Fudge

What causes peanut butter fudge not to harden? ›

The amount of time you cook fudge directly affects its firmness. Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.

How do you keep peanut butter fudge from being grainy? ›

It is also important to prevent stray sugar crystals from "seeding" your mixture and bringing crystals out of your supersaturated solution prematurely and creating a grainy fudge - people usually control for this in one of three ways: by buttering the sides of the cooking pan, by briefly covering the boiling mixture so ...

Why did my peanut butter fudge turn out crumbly? ›

Candy that isn't cooked long enough will end up too soft; overcooking makes fudge crumbly or hard. High-quality fudge has many small crystals. If the process of crystallization begins too early, fewer crystals form and they become much larger.

Is evaporated milk or condensed milk better for fudge? ›

Evaporated milk doesn't have sugar added. The sweetened condended milk is needed as no extra sugar is added to the fudge. If evaporated milk were used then the fudge would not be sweet enough and also would still be too soft unless the fudge is frozen.

Can you fix peanut butter fudge that didn't set? ›

OPTION 3) Sieve together some powdered sugar and cocoa powder, and gradually work this into your unset fudge until it reaches the consistency of dough, then roll out and cut into squares, or shape into balls and then roll in powdered sugar (roll the balls in icing sugar, not yourself).

What is the secret to smooth fudge that is not gritty? ›

Once a seed crystal forms, it grows bigger and bigger as the fudge cools. A lot of big crystals in fudge makes it grainy. By letting the fudge cool without stirring, you avoid creating seed crystals.

Should I stir fudge while boiling? ›

Stir the ingredients to dissolve the sugar until the mixture comes to a boil. If your recipe uses milk, stirring will keep the mixture from curdling. But once it reaches about 236–238 degrees F/113–114 degrees C (the "soft-ball" stage), do not stir it or even shake the pan.

Why is my peanut butter fudge gooey? ›

If the humidity was too high, it would come out sticky and gooey and there was nothing you could do about it.

How long do you boil fudge to get to soft ball stage? ›

How long does it take to make fudge:
  1. about 18 min to reach boiling.
  2. about 40 minutes to reach soft ball stage.
  3. 60 minutes to cool.
  4. 28 minutes to beat in a KitchenAid (your time for this may vary)
  5. 4 hours to set.

Can you remelt grainy fudge? ›

Pour the fudge back into your pan, and add about a cup of water to it, along with a tablespoon or two of evaporated milk, whipping cream, or whatever cream you're using. Some people skip the water and just add cream to the mixture to reheat.

What to do if peanut butter fudge doesn t set? ›

I generally heat my syrup up to 235° F and let carry-over do the rest of the work. If it's overcooked (resulting in grainy fudge) or undercooked (resulting in poor setting) all you really need to do is add a bit of cream, reheat the fudge to the target temperature, and let it set again.

What happens if you overboil fudge? ›

Too cooked

This fudge was cooked to a temperature of 118 °C (244 °F). At this temperature, the sugar is too concentrated and there is not enough water left to form syrup around sugar crystals. The result is hard and brittle fudge.

Why does my fudge crack when I cut it? ›

There are 2 reasons that fudge will crumble: overcooking & having an undissolved sugar crystal in the mixture. That undissolved crystal will cause the dissolved sugar to recrystalize (think rock candy).

What makes high quality fudge? ›

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).

Do you stir fudge while it is boiling? ›

Brush the sides of the pan with a wet brush at the beginning of cooking to dissolve sugar crystals stuck to the sides. Never stir the mixture during cooking or sugar could crystallize again. The mixture may seize and become grainy. Use a candy thermometer or conduct a cold water test to check if the fudge is done.

What gives fudge its firm texture? ›

The key to creamy, luscious fudge is controlling crystal formation. If the sucrose (table sugar) crystals are small, the fudge will feel creamy and smooth on your tongue. But if the crystals are large, the fudge develops a crumbly, dry, or even coarse texture.
