What You’ll Need For Easy Microwave Fudge

Peanut butter and Reese’s means twice the peanut butter flavor in every bite. Scroll down to the recipe card at the bottom of the post for exact amounts.

  • Butter: You can use salted or unsalted butter. If using unsalted, add 1/4 teaspoon salt.
  • Peanut Butter: Use standard creamy peanut butter.
  • Vanilla Extract: It helps round out the flavors but feel free to skip it.
  • Powdered Sugar: Don’t use granulated sugar or the fudge will turn out grainy.
  • Reese’s Peanut Butter Cups: You can use all full size cups, mini peanut butter cups or a mixture of the two!

What Type of Peanut Butter is Best for Fudge?

Both smooth and chunky peanut butter are great for this easy peanut butter fudge recipe. The only difference is the texture they’ll add. Smooth peanut butter gives the fudge a creamy texture, whereas chunky adds texture regardless of whether your add-ins are crunchy. Avoid natural peanut butters because the oil and peanuts will separate over time and the texture will not be the same.

  • Prep: Lightly butter a baking dish and line it with parchment paper or aluminum foil.
  • Heat and Stir: Microwave the butter and peanut butter until the butter melts. Stir and heat it again.
  • Combine: Stir the vanilla extract and powdered sugar into the butter mixture until smooth. The mixture will thicken and lose its sheen.
  • Assemble: Spread the peanut butter mixture into the prepared pan and top with Reese’s cups. Or you can add half the fudge mixture, followed by a layer of Reese’s cups, and top with remaining fudge and Reese’s cups.
  • Chill: Pop fudge into the fridge to chill until the mixture is firm. Cut it into 1″ pieces and enjoy.

Tips for Success

Any easy peanut butter fudge recipe can be taken to the next level with a fruit jam swirl or chopped mini pretzels.

  • Let it chill: The more you let the fudge chill, the less chances you have of it being melty and sticky when you slice it or serve.
  • Add a base: You can add a layer of graham crackers or wafer cookies along the bottom of the baking dish and pour the fudge on top. When it sets, you have a cookie-fudge combo.
  • PB&J Fudge: Microwave 1/4 cup strawberry or blackberry jam to make it runny. Swirl it into the fudge mixture and let it set for a touch of fruitiness.
  • Use more add-ins: Chopped mini pretzels, peanuts, pecans or mini chocolate chips are great ways to add more flavor and texture to each bite.
  • Add a drizzle: Use salted caramel sauce or chocolate sauce to add a sweet drizzle right before refrigerating the fudge. It’ll make it extra pretty!
  • Choose the right baking dish: The larger it is, the more spread out the fudge will be. Stick to an 8×8″ baking dish for a thicker fudge, or double the recipe if using a 9×13 pan.

How To Store Microwave Peanut Butter Fudge

Cut strips of parchment paper and place them between the pieces of this homemade peanut butter fudge to keep them from sticking.

  • On the counter: Place the fudge in an airtight container for up to 2 weeks. Store it away from direct heat to keep it from melting. This method isn’t great if the area where you live is warm and humid.
  • In the fridge: Refrigerate it in an airtight container for up to 3 weeks. Keep it away from strong-smelling foods like onions.
  • In the freezer: Wrap each piece in plastic wrap and place it in a freezer-friendly bag or container. Freeze for up to 3 months. Thaw it on the counter to room temperature before digging in.

FAQs

What is the secret to perfect 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 didn't my microwave fudge harden? ›

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.

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.

How do you thicken microwave fudge? ›

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 make fudge creamy and not grainy? ›

How to Fix Grainy Fudge. If, despite your best efforts, your fudge is grainy when you go to transfer it to your pan, never fear! You can fix it. Just place the fudge mixture back in a saucepan on the stovetop with about 1½ cups of water and slowly melt the fudge to a smooth liquid.

Should you stir fudge while it's cooking? ›

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.

Can I 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 microwave fudge grainy? ›

Fudge usually behaves this way when it's not cooked to a high enough temperature (due to oversight or a faulty candy thermometer). 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.

Why won't my 3 ingredient condensed milk 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. Heat in 30-second bursts in the microwave, stirring well between each to ensure everything is melting evenly.

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

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.

When to stop beating fudge? ›

Once the mixture has cooled enough, use a wooden spoon or an electric hand mixer to beat the fudge until you see the very first signs of the mixture shifting from glossy to matte. Believe yourself when you think you see them! If you over-mix the fudge it will set in your pot.

Why is my microwave fudge not setting? ›

You didn't cook it long enough. Fudge needs to be heated to the "soft ball" stage. It is salvageable, but you'd have to be very careful of sugar crystallization.

What makes fudge firmer? ›

Monitor the Temperature with a Candy Thermometer

If you end up with soft fudge that turns into a puddle in your hands or hard fudge that is a bit reminiscent of a crunchy candy, improper temperature is likely to blame. If you don't heat your fudge to a high enough temperature, you'll end up with a soft product.

Will powdered sugar thicken fudge? ›

How to thicken your fudge? If your fudge it noticeably thin, you may want to add more chocolate. If you are out of chocolate, you can also add 1/4-1/2 cup of powdered sugar. This, however, can make the fudge very sweet.

What gives fudge its firm texture? ›

Tiny microcrystals in fudge are what give it its firm texture. The crystals are small enough, however, that they don't feel grainy on your tongue, but smooth. While you ultimately want crystals to form, it's important that they don't form too early.

What makes fudge moist? ›

Monitor the Temperature with a Candy Thermometer

If you end up with soft fudge that turns into a puddle in your hands or hard fudge that is a bit reminiscent of a crunchy candy, improper temperature is likely to blame. If you don't heat your fudge to a high enough temperature, you'll end up with a soft product.

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!

How to prevent fudge from being grainy? ›

Prevent Graininess Before It Starts

The most common reason for graininess is because you began beating or stirring it while the fudge was still cooling. It's best to wait until it's cooled to somewhere around 110 to 113 degrees to begin stirring.
