In This Recipe

My partner’s mom makes peanut butter fudge on what seems like a weekly basis. I’m not sure how she can consume so much of it. She has a dedicated baking pan just for this peanut butter fudge and there’s always a tub of it in the fridge.

But when I emailed her asking for the recipe, she didn’t know how to give it to me. Like most recipes of hers, she free-forms it, adding peanut butter until the batter “looks and feels” right.

It looked like I'd need to head into the kitchen and do some experimenting!

The Secret to Easy Peanut Butter Fudge

The one thing she did casually mention was that she uses marshmallows in her peanut butter fudge, something I'd never thought about. When I make fudge, I often use the old-fashioned method, which requires cooking the sugar to a soft-ball stage of 238°F. It’s fussy and always put me off of making fudge.

But since the sugar in marshmallows has already been cooked and turned into a candy, using them to make the peanut butter fudge seemed like an easy and totally acceptable cheat.

And easy it was! This easy peanut butter fudge recipe is a snap to make and super smooth. So easy that I’m fearful I’ll end up like her, making this easy peanut butter fudge on a weekly basis. I can feel my waistline expanding already.

The Best Peanut Butter for Fudge

I use smooth peanut butter in this fudge, but if you prefer a little texture, feel free to use the same amount of chunky peanut butter in its place.

You'll get the best results if you stick with commercial brands of peanut butter (Jif, Skippy, Peter Pan). Natural peanut butter has a tendency to separate, and it can sometimes interfere with how the fudge sets up. (If you do want to try using natural peanut butter, just make sure it's very well-stirred and the oil is well incorporated.)

Subs and Additions to Peanut Butter Fudge

  • Substitute coconut milk for a non-dairy version of this fudge
  • Make chocolate peanut butter fudge by drizzling melted chocolate over the top, or sprinkling chocolate chips on top right after smoothing out the fudge in the pan and gently pressing them in.

How to Store Peanut Butter Fudge

Store this fudge in an airtight container. The fudge keeps for about a week at room temperature or 2 to 3 weeks refrigerated.

To freeze, wrap the chilled fudge in plastic wrap and then transfer to a freezer storage bag. Freeze for up to a month and thaw in the fridge.

Mini vs. Regular Marshmallows

You need marshmallows for this recipe, but there's wiggle room with the size of the marshmallows.

  • 10 miniature marshmallows is the equivalent of 1 regular marshmallow. Substitute 60 miniature marshmallows for the 6 regular-sized ones in this recipe.
  • 4 regular marshmallows are the equivalent of 1 jumbo marshmallow. Substitute 1 1/2 jumbo marshmallows for the 6 regular-sized ones in this recipe.
  • You cannot substitute marshmallow creme for the marshmallows. Marshmallow creme doesn't have any gelatin, and this recipe requires the gelatin for the fudge to set.

How to Package Peanut Butter Fudge for Gifts

Homemade fudge makes a thoughtful gift. These tips will help you package it for gift giving.

  • Wrap cooled and then refrigerated fudge tightly in plastic wrap so it does not dry out.
  • Add a layer of parchment paper around the plastic wrap. It will look nicer when the recipient opens the box.
  • Put the fudge in an appropriately sized box. You can buy candy boxes at a craft store that will work well as gift boxes.

To send the fudge, you'll need two boxes—one for boxing up the fudge and one to place that box, or boxes, of fudge in.

  • Use packing material so the box that the fudge is in does shift in the shipping box.
  • If you're shipping during warmer months, you'll need frozen gel packs or dry ice and an insulated shipping container or the fudge may melt.
  • If you're shipping during colder months, you can mail the fudge without the assistance of a cold pack or dry ice.

Freezing Peanut Butter Fudge

This fudge freezes well, so it's a convenient, crowd-pleasing treat to make ahead of a party. Make it in batches as written; we don't recommend doubling the recipe.

To freeze, cool the fudge completely and wrap in one large piece in plastic wrap. Place the wrapped fudge in a freezer safe zipper bag. Defrost in the refrigerator.

You'll get the best results if you stick with commercial brands of peanut butter (Jif, Skippy, Peter Pan). Natural peanut butter has a tendency to separate, and it can sometimes interfere with how the fudge sets up.

Have your lined baking pan ready to go before you start and work fast once you remove the saucepan from the heat. As the fudge starts to cool, it can become difficult to work with.

Ingredients

  • 1/2 cup whole milk

  • 6regular-sized marshmallows, certified gluten free if needed

  • 3/4 cup (150g) sugar

  • 3/4 cup (165g) light brown sugar

  • 2 teaspoons vanilla extract

  • 1/2 teaspoon kosher salt

  • 1 1/2 cups (420g) smooth peanut butter (notnatural peanut butter, see Recipe Note)

Method

  1. Prepare the baking pan:

    Lightly spray an 8 x 8-inch baking pan with cooking oil. Line with parchment paper.

  2. Warm the milk and marshmallows:

    Place the milk and the marshmallows in medium pan. Turn the heat to medium low and gently heat the milk. Stir constantly until the marshmallows have melted. If the milk starts to foam up too much, reduce the heat.

  3. Stir in the sugars, followed by the remaining ingredients:

    Once the marshmallows have melted, add both sugars and continue to cook on medium low heat while stirring until the sugars have dissolved and the liquid is smooth. Add the vanilla, salt, and peanut butter. Stir until smooth and incorporated into the batter.

  5. Cool overnight:

    Let the fudge cool to room temperature in the pan, then chill in the fridge overnight.

  6. Cut the fudge:

    The next day, lift the fudge from the pan using the parchment paper and cut into 1-inch squares.

    Store in an airtight container. The fudge keeps for about a week at room temperature or 2 to 3 weeks refrigerated.

FAQs

What is the secret to good fudge? ›

How to Make Fudge. The trick to good homemade fudge is to cook the ingredients to the right temperature to form a sugar syrup, and cool the mixture properly so the texture of the fudge turns out smooth and firm, but soft enough to cut. Here's how to make fudge on your stovetop and in your microwave.

Why won t my peanut butter fudge harden? ›

Fudge Didn't Set

If your fudge turned out super sticky, or it didn't set as it cooled, it probably never got hot enough. This mistake is super easy to avoid if you use a candy thermometer and cook the fudge to the temperature specified in the recipe (usually between 234 and 239°F).

Why is my peanut butter fudge dry and crumbly? ›

If your fudge is tough, hard, or grainy, then you may have made one of several mistakes: You may have overcooked it, beaten it too long, or neglected to cool it to the proper temperature. Don't throw out the whole pan, because you may be able to melt the fudge down and try again.

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.

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.

Why is my 3 ingredient fudge not setting? ›

Why won't my 3 ingredient fudge set? This often happens when the condensed milk and chocolate chip mixture isn't hot enough to start. Everything must be completely melted before it is transferred to the pan to cool.

What happens if you boil fudge too long? ›

If there is too much evaporation, when the cooking time is too long, there will not be enough water left in the fudge and it will be too hard.

Do you refrigerate fudge to set? ›

The ratio of chocolate to condensed milk needs to be just right, otherwise you might end up with fudge that is too soft or too hard. Do not freeze the fudge to set it. Best way is to just be patient for a couple hours and set it in the fridge. If your fudge hasn't set, then you've gone wrong somewhere else.

Why is my peanut butter fudge chewy? ›

If the fudge is very soft and slightly chewy then it is possible that it did not quite cook to soft ball stage and next time the mixture should be cooked to a slightly higher temperature (soft ball is 112-116c/235-240F and a sugar or candy thermometer can help).

Can you fix grainy peanut butter fudge? ›

The solution? A fudge do-over. Even though it set up properly, I threw it back into a saucepan with about 1 1/2 cups of water and gently heated the mixture to dissolve the fudge into the water. From there, I pretty much re-did the whole cooking process.

What temperature should fudge be cooked at? ›

Cook until the correct temperature

Confectionery experiments have shown that the ideal cooking temperature for fudge is around 114 to 115 °C (237 to 239 °F).

Can you reboil fudge that hasn't set? ›

How can you fix soft fudge? Put it in a microwave safe bowl that is large enough that it won't boil over. Reheat it to the boiling point and cook for about 3 more minutes. Then you can beat some powdered sugar into it if this doesn't make it set.

How to fix oily peanut butter fudge? ›

One of the most common problems that arises making this delicious treat is when the fudge ends up overly oily. Fortunately, fixing the issue is fairly simple. Put the greasy mix back into a pot, add a few tablespoons of water, and stir the fudge on a low heat. Once this new mixture is complete, rebake the fudge.

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.

Why did my fudge turn out like taffy? ›

If the temperature is too low, the fudge will be too soft and sticky, and if it's too high, it will turn into a hard, crumbly mess. The ideal temperature to cook fudge is between 232-234 degrees F (111-112 degrees C).

What makes fudge so good? ›

It's the size of sugar crystals that makes the knees of fudge lovers buckle…the smaller the crystals, the less they are perceived on the tongue and the more the fudge tastes smooth and creamy. Cooking, and beating after cooking, is the key to successful fudge.

What does cream of tartar do in fudge? ›

Cream of tartar is used in caramel sauces and fudge to help prevent the sugar from crystallizing while cooking. It also prevents cooling sugars from forming brittle crystals, this is why it's the secret ingredient in snickerdoodles!

What keeps fudge from getting hard? ›

If fudge is left unwrapped or accidentally put in a cold area/refrigerator then the result can be hard fudge. It is possible (but not guaranteed) to reverse this process by wrapping up your fudge in several layers of clear wrap. This allows the moisture to re-permeate into the fudge & make it soft again.

How do you describe high quality fudge? ›

High-quality fudge tastes smooth and creamy because it contains small sugar crystals. It has a deep brown color and a satiny sheen. Poor-quality fudge tastes grainy because it contains large sugar crystals.
