Recipe for Peanut Butter Fudge

This fudge recipe has become my go to fudge recipe due to how quickly the fudge sets, I typically do still wait a couple hours before slicing it, but it seems to be nearly complete and set after about an hour. Fudge in an hour, that’s amazing!! Also, unlike many other fudge recipes, this one does not require a ton of stirring or attention to the exact temperature of the mixture. I enjoy making this recipe with creamy peanut butter, it produces a smooth and creamy texture that is perfect. But sometimes it is fun to mix it up and use a crunchy peanut butter, who doesn’t love a little crunchy in their fudge? No matter how you choose to make this fudge the results you will achieve a nothing less than fudge perfection!

How to make Peanut Butter Fudge

Prep

Prepare an 8X8 (or 9X9) square pan with buttered foil. To do this, cut a piece of foil that is slightly larger than the pan and then spread softened butter on the foil with a spatula or by placing your hand in a plastic bag like a glove and using your fingers to spread the butter on the foil. Press the foil into the pan, butter side up. The foil should come at least most of the way up the sides.

Making the Fudge

Next, in a medium saucepan, bring the sugar and milk to a boil over medium heat, stirring occasionally. Boil for 2 1/2 minutes.

After the 2 1/2 minutes, remove the mixture from heat and add the peanut butter and vanilla extract, stirring until smooth.

Set and serve

Proceed to pour the fudge mixture into prepared pan and let set for about 1-2 hours in the refrigerator before slicing and serving.

To slice, just remove the entire foil from the pan and fold the edges down flat. It is so much easier to slice and serve this way than trying to do it while it is still in the pan!

Serve and enjoy!

Easy Peanut Butter Fudge Recipe FAQ

What kind of peanut butter is used in Peanut Butter Fudge?

I always make this recipe with regular creamy peanut butter and it works perfectly for achieving that smooth, fudgy texture. If you like a bit of crunch and texture, I think that crunchy peanut butter would work really well in this recipe too. Use a regular peanut butter like Jif or Skippy for best results – I have found that more natural peanut butters (the ones where the oil is separated out) usually don’t work as well in baking, most likely because they tend to be a little bit runnier.

Why is my peanut butter fudge not setting?

If your fudge isn’t setting, double check that you added the full 2 cups of sugar to the pan. Make sure you brought the fudge to a full boil before starting your 2:30 timer.

Why is my peanut butter fudge dry and crumbly?

Make sure you didn’t overcook the fudge to avoid it getting dry. The best way to avoid this is by setting a timer when you’re cooking the milk and sugar.

What ingredient makes fudge hard?

Milk and sugar boil together to make a type of candy, which, when combined with the peanut butter, cool and harden to make the fudge.

What causes peanut butter fudge to be grainy?

You can stir the sugar and milk while they are cooking to make sure all the sugar granules dissolve and avoid grainy fudge.

Why is my peanut butter fudge oily?

Oily fudge happens most often as a result of the type of peanut butter used to make it. Natural peanut butters tend to be more separated, resulting in oily fudge. I recommend using basic Jif or Skippy to make this fudge recipe.

Storing Easy Peanut Butter Fudge

Does homemade peanut butter fudge need to be refrigerated?

Peanut Butter fudge should NOT be refrigerated as it tends to dry out the fudge.

Can you freeze fudge?

Yes! Freezing fudge is easy. Just double wrap it in plastic wrap or parchment paper, then store it in an airtight container. Will stay fresh for 3 months. Thaw and cut into squares to serve.

FAQs

Why is my peanut butter fudge not getting hard? ›

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 use unsalted butter in fudge? ›

Butter is added in the final stages to add flavor and smoothness and inhibit large crystal formation. Use unsalted butter so you can add a small amount of salt (¼ teaspoon per stick of butter) to the sugar/liquid mixture. Salt tends to stabilize the mixture and keep it from foaming as much.

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

What is butter fudge made of? ›

Sugar, Glucose Syrup, Full Cream Condensed Milk, (Milk, Sugar, Lactose), Non Hydrogenated Vegetable Fat (Palm, Palm Kernal Oil), Salted Butter (4%) (Butter, Salt), Fondant (Sugar, Glucose Syrup, Water), Salt.

Can you fix fudge that didn't set? ›

OPTION 1) Depending on how runny it is, you can either use it as a frosting for cakes, or a sauce for ice-cream. OPTION 2) Freeze it overnight. Cut it into squares. Cover each square thickly in melted chocolate, ensuring no part of the fudge is exposed.

What happens if you use regular butter instead of unsalted? ›

You can definitely use salted butter and unsalted interchangeably. If a recipe calls for unsalted butter and additional salt, just use a little less of the salt that the recipe calls for. That's the only tweak you need to make!

What is a substitute for salted butter? ›

Substitutes for Salted Butter

Salted butter differs from unsalted because it's preseasoned with (you guessed it) salt. So for 1 cup of salted butter, trade 1 cup margarine or 1 cup shortening plus ½ teaspoon salt; ⅞ cup vegetable oil plus ½ teaspoon salt; or ⅞ cup lard plus ½ teaspoon salt.

Can I use salted butter instead of unsalted for fudge? ›

Choose the right butter – You can use salted or unsalted butter, though using salted gives it a bit of contrast, like salted caramel. If you'd prefer to enjoy the richness of chocolate, choose unsalted butter. Don't over-stir the fudge.

How do you make fudge creamy and not grainy? ›

It's not brittle or crumbly, at least not unpleasantly so. By cooling the fudge prior to agitation (like in the recipes included in this article), on the other hand, you'll get much smaller, finer sugar crystals and a finished fudge with a smooth, creamy texture.

Why is my peanut butter fudge dry and crumbly? ›

Follow the recipe to a tee when cooking the sugar

However, it's important to bring the sugar to the exact right temperature. If it doesn't boil, your fudge will end up too mushy, and if it cooks for too long, you'll end up with a dry, crumbly mess.

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 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 is traditional fudge made of? ›

Fudge is a dense, rich confection typically made with sugar, milk or cream, butter and chocolate or other flavorings. The base for fudge is boiled until it reaches the soft-ball stage (135 to 140 degrees F), then stirred or beaten as it cools to minimize the formation of sugar crystals.

Does fudge need parchment paper? ›

Use the size recommended in your recipe, otherwise a larger pan produces thinner pieces of fudge, and a smaller pan produces thicker pieces. To keep the fudge from sticking to the cooling pan, line it with non-stick foil or parchment paper, or coat it with cooking spray, butter, or a neutral oil.

How do you fix runny peanut butter fudge? ›

Bring the fudge back to a boil with 1–2 US tbsp (15–30 ml) of cream. If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream.

How long does it take for fudge to go hard? ›

Pour Fudge into Prepared Pan
