The Easiest Creamy Peanut Butter Fudge Whips Up In Minutes!
Chocolate gets all the attention when it comes to fudge, but I am not joking when I say that this recipe for peanut butter fudge is not only incredibly simple, it is the BEST combination of salty, sweet, and creamy!! And you don’t even need an oven or stovetop to make it, which means this is a perfect treat to make in the summer when you don’t want to heat up the kitchen.
My family is absolutely addicted to this ultra-easy, ultra-creamy peanut butter fudge. And as a side note, from personal experience, if you leave the fudge out on the counter for too long you simply won't have any left over!
But it’s also a great gift around the holiday season - make several batches and wrap them with a pretty bow for friends and family! This creamy fudge is the perfect addition to your holiday baking!
All you need is four ingredients and a microwave! Yep - you read that right. Delicious fudge made in the microwave. It doesn’t get any easier!
- Sweetened Condensed Milk - This is the best choice for fudge, as it won’t curdle when cooked at a high temperature and has a sweet, caramelized taste.
- White Chocolate Chips - These rich and creamy white chocolate chips are the base of many fudge recipes!
- Creamy Peanut Butter - Use your favorite brand! However, the natural brands will not be quite as creamy as Jif, Skippy, or their generic brand equivalents.
- Vanilla Extract - Be sure to use real vanilla for the best taste, as this heightens all of your ingredient flavors.
- Dry Roasted Peanuts - These are completely optional, but add extra peanutty flavor and a wonderful crunch to your fudge.
🔪 Step-by-Step Instructions
Start out with some quick prep of lining your baking pan, then gather ingredients. Toss everything directly into a microwave-safe dish and voila! You'll have fudge ready to set in no time!
- Choose your baking pan - a 9x13 is perfect for this recipe, but use an 8x8 if you like thicker fudge. Cover the entire pan with parchment paper (edges should hang over the side of the pan), for super easy clean-up and removal of the chilled and set fudge slab. *If the paper isn’t fitting well into the pan, you can crumple it a few times and stretch it.
- Take a medium-sized, microwave-safe bowl and combine all of the ingredients, including 2 cups white chocolate chips, 14 ounce can of sweetened condensed milk, ½ tablespoon of vanilla extract, ½ cup of creamy peanut butter, and the optional 1 cup of roasted peanuts.
- Heat the combination of ingredients on high in the microwave, stopping every 30 seconds to stir. Do this until everything is melted and smooth, approximately 1- 1 ½ minutes. *Small pieces of white chocolate will dissolve with stirring.
- Pour the entire mixture into your prepared baking pan and smooth the top with a spatula.
- Place the fudge in the refrigerator to chill and set completely, which will take at least an hour. Remove the pan and cut the fudge into one-inch squares for serving.
*Note that if you use a smaller pan for thicker squares of fudge, the cooling and setting time can take longer.
This creamy, decadent fudge goes great with a hot cup of coffee or tea or a big glass of milk!
🥡 Storing & Reheating
Your microwave peanut butter fudge will keep in the refrigerator in an air-tight container for up to three weeks - but it surely won’t stay around that long! Also note that your fudge can pick up flavoring from other refrigerated items.
So, yes, it is best to store the fudge in an airtight container. Place sheets of parchment paper between the layers and store at room temperature for up to 1-2 weeks.
Keep the fudge tucked away in a pantry rather than on the countertop. If your fudge gets a bit mushy or soft, you can place it out for an hour or two to firm up again.
If you make several batches and want to freeze some, you can wrap the entire block of fudge in cling film, or cut it into pieces and wrap them individually. Then place in a freezer-safe plastic bag to keep it fresh for up to three months.
To thaw, simply remove from the freezer and place in the refrigerator until soft.
Fudge that doesn't set up after cooling, but isn't grainy, didn't reach a high enough temperature while cooking the fudge. Return your fudge to a microwave-safe bowl and add 1 ½ cups water. Heat until melted again and the water is fully combined with your fudge. Double-check the fudge temperature using a candy thermometer. Once it is between 235-245 degrees F (113-118 degrees C) it has reached the 'soft ball' stage that fudge needs for setting correctly.
Stirring too much during cooling allows the sucrose molecules to form crystals (basically forming sugar crystals). Resist the urge to stir and simply transfer the fudge to your prepared pan, spread, and refrigerate to set.
Microwave Peanut Butter Fudge
- 14 ounces sweetened condensed milk (1 14 ounce can)
- 2 cups white chocolate chips
- ½ cup creamy peanut butter
- ½ tablespoon vanilla extract
- 1 cup dry roasted peanuts (optional)
- prepare either an 8x8 baking pan (for thicker fudge pieces) or a 9x13 baking pan with a sheet of parchment paper. Leave the parchment paper overhanging two sides to be your handles for easy removal of the set fudge. *Parchment paper can be crumpled up and stretched, repeating a few times to make it fit into baking pans easier.
- In a medium-sized mixing bowl combine all of the ingredients including the 14 ounce can of sweetened condensed milk, 2 cups of white chocolate chips, ½ cup of creamy peanut butter, ½ tablespoon of vanilla extract, and the optional 1 cup of dry roasted peanuts.
- Heat the ingredients on high power in 30-second increments. Stir between each heating until fully melted, about 1 - 1 ½ minutes.
- Transfer the melted fudge mixture into your prepared baking dish and smooth the top using a spatula.
- Chill the microwave peanut butter fudge in the refrigerator for at least an hour, or until fully set. Remove from the pan and cut into approximately 1-inch squares for serving.
Store your fudge in an airtight container in the refrigerator for up to 2-3 weeks. To freeze your peanut butter fudge, wrap either your cut pieces or the whole slab tightly in plastic cling film. Place the wrapped fudge into a freezer storage bag and freeze for up to 3 months. Thaw frozen fudge in the refrigerator until soft enough to serve.
