Ingredients

The beauty of this Easy Peanut Butter Fudge lies in its uncomplicated yet flavorful ingredients. A mere four components come together to create a symphony of taste and texture. Let's take a closer look at what makes this recipe so effortlessly delicious.

  • Unsalted butter - serves as the rich and creamy base of the fudge. It provides a smooth texture and a subtle, buttery flavor without the risk of the fudge becoming overly salty.
  • Creamy peanut butter - is the star of the show, responsible for the flavor and achieving that melt-in-your-mouth goodness.
  • Vanilla extract - adds depth and enhances the overall flavor profile of the fudge.
  • Powdered sugar - the sweetening agent and also contributes to the fudge's texture. The powdered sugar combines seamlessly with the other ingredients, creating a sweet and decadent "dough" that sets the foundation for the fudge.

Even if you're a novice in the kitchen, you'll be amazed at how effortlessly this peanut butter fudge comes together. Follow these simple steps, and you'll soon be relishing in the delight of your own homemade masterpiece.

  1. Butter the pan and line it with parchment paper for easy removal.

  3. Stir in vanilla and powdered sugar for a smooth, delectable dough.

Storage Tips for Your Peanut Butter Fudge

While the temptation to devour this delightful creation might be strong, knowing how to store it properly ensures lasting freshness. Store in an airtight container at room temperature for up to one week. If you're in a warm climate, you may need to store in the fridge.

Gifting Peanut Butter Fudge

Personalizing peanut butter fudge for gifting is a wonderful idea. Here are some creative ways to add a personal touch:

  • Packaging: Use decorative boxes, jars, or cellophane bags to present the fudge beautifully.
  • Add-ins: Customize the fudge by folding in extras like chopped nuts, dried fruit, or even chocolate chips to create unique flavor combinations.
  • Decorate: Drizzle melted chocolate on top, sprinkle crushed nuts, or dust with cocoa powder for an extra visual appeal.
  • Gift Tags: Attach personalized gift tags with a handwritten note or the recipe, sharing the joy of your homemade creation.

Can I Freeze Peanut Butter Fudge?

Yes, you can freeze peanut butter fudge for longer storage. To do so:

  1. Wrap Well: Ensure the fudge is well-wrapped in plastic wrap or aluminum foil to prevent freezer burn.
  2. Airtight Container: Place the wrapped fudge in an airtight container for added protection.
  3. Label: Clearly label the container with the date to keep track of freshness.
  4. Thawing: When ready to enjoy, allow the fudge to thaw in the refrigerator to maintain its texture.

Note that freezing may slightly alter the texture, so consider freezing smaller portions for easier thawing and consumption.

Can I use salted butter instead of unsalted butter?

While you can use salted butter, it's recommended to stick with unsalted butter in this peanut butter fudge recipe. Using unsalted butter allows you better control over the overall saltiness of the fudge. If you opt for salted butter, expect a saltier tasting fudge.

Peanut Butter Fudge

Only 4 ingredients and 4 minutes to make this wonderful peanut butter fudge. Doesn't get better than that!

Prep Time6 minutes mins

Cook Time4 minutes mins

Total Time10 minutes mins

Course: Candy, Dessert

Cuisine: American

Keyword: easy peanut butter fudge, microwave peanut butter fudge

Servings: 64 1-inch pieces

Calories: 77kcal

Author: Nikki Gladd

Ingredients

  • 1 cup unsalted butter , plus additional for greasing pan
  • 1 cup creamy peanut butter
  • 1 teaspoon pure vanilla extract
  • 1 lb powdered sugar (or about 3 ¾ cups), unsifted

Instructions

  • Butter the bottom and sides of an 8- x 8-inch pan, and then line the bottom and sides of the pan with a sheet of parchment paper. (The butter helps the paper stick to the pan.) Lightly butter the top of the parchment paper, as well.

  • Combine the 1 cup butter and peanut butter in a large microwave safe bowl, cover with plastic wrap and microwave on full power for 2 minutes. Carefully remove the bowl from the microwave, uncover and stir with a rubber spatula or wooden spoon. Recover and microwave on full power for an additional 2 minutes.

  • Remove the bowl from the microwave. Carefully stir in the vanilla and powdered sugar until evenly combined. The mixture may become a little crumbly at first, but continue to stir until the ingredients are smooth and a nice "dough" forms.

  • Pour the mixture into the prepared pan and spread into an even layer, pushing to fill the corners. Place an additional square piece of parchment paper directly on the surface of the fudge and use your hands to smooth the top.

  • Refrigerate at least 2 hours. Once chilled, transfer fudge to a cutting board by lifting the sides of the parchment paper. Use a large knife to cut into 1-inch cubes.

  • Store in an airtight container at room temperature for up to 1 week.

Notes

Be careful when measuring the powdered sugar. 1 lb (or 16 oz) of powdered sugar is equal to 3 ¾ to 4 cups. Do not think in terms of liquid measurement where 16 ounces equals only 2 cups.

FAQs

What is the trick to making 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).

Why is my fudge not setting in the microwave? ›

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.

Why did my peanut butter fudge not get hard? ›

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.

Why is my 3 ingredient fudge not setting? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.

How do you make fudge creamy and not grainy? ›

Why is my microwave fudge grainy? ›

Graining can be caused by stirring the fudge mixture during the cooling process or not adding enough fluid to dissolve the sugar. The trick to fixing graininess is to melt the sugar crystals to give them another chance at setting properly.

Can you fix 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).

Why is my fudge so runny? ›

Another key part of a successful fudge texture is when you stir the mixture. Stirring the sugar and milk during the initial stages of cooking allows the sugar to dissolve. However, once the mixture comes to a boil, it's time to put the spoon down.

What makes fudge softer? ›

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. Conversely, if the cooking time is too brief and there is not enough evaporation, too much water will remain and the fudge will be too soft.

Why won't my microwave fudge set? ›

The most common culprit behind unset fudge is inaccurate temperature control. If the sugar mixture hasn't reached the correct temperature, your fudge won't set. Ensure you use a reliable candy thermometer and follow temperature guidelines meticulously to achieve the desired consistency.

How do you make homemade fudge firmer? ›

How do you beat fudge? ›

When the fudge cools to 110 degrees F/43 degrees C, beat the mixture vigorously with a wooden spoon until it's no longer glossy. Then you can stir in the nuts, or any other extra flavorings, and transfer it to the cooling pan. Adding Butter to Fudge | Photo by Meredith.

How to prevent fudge from being grainy? ›

Prevent Graininess Before It Starts

Can you beat fudge in a stand mixer? ›

Pour the mixture over the chocolate, being sure to shake, not scrape, the mixture from the pot. Set aside to cool for 10 to 12 minutes. (This prevents a grainy consistency.) Using the clean wooden spoon or a standing mixer on low speed, stir or beat the mixture until the chocolate is completely melted and incorporated.

What is the ball method fudge? ›

According to most recipes, the ingredients of fudge are cooked to what is termed in kitchen parlance the soft ball stage, that point between 234 and 240 °F (112 and 115 °C) at which a small ball of the candy dropped in ice water neither disintegrates nor flattens when picked up with the fingers.
