Sweet tooth, this simple recipe was made for you!

The best peanut butter fudge is an easy recipe to make for the Christmas or throughout the holiday season. Okay, let's be honest, it's really great any time of the year.

It’s melt in your mouth delicious. Excuse me while I drool….

Ingredients

You'll only need four simple ingredients to make this peanut butter fudge recipe.

• unsalted butter
• peanut butter - pick whatever brand of peanut butter is your favorite. I like the smooth texture of creamy peanut butter but you can use crunchy peanut butter if you want a different texture. If you have extra peanut butter, try making these chocolate peanut butter brownies.
• vanilla extract
• powdered sugar

Substitutions

In traditional peanut butter fudge recipes, butter plays a crucial role but you can opt for coconut oil as an alternative. It will still have a similar texture and rich flavor.

How to make peanut butter fudge in the microwave

Step #1: Combine the butter and peanut butter in a microwave-safe bowl.

Cook in the microwave in 30 second intervals, stirring in between, until smooth and creamy.

Add the vanilla to the peanut butter mixture and stir.

Step #2: Add the powdered sugar to a large bowl. Pour in the peanut butter mixture.

Stir together until everything is combined and is creamy. 

Step #3: Line an 8x8 square pan with aluminum foil or parchment paper with excess foil or paper hanging off the side.

Spread your homemade peanut butter fudge into the prepared pan smoothing out the top with an offset spatula.

Use the back of a spoon to create a swirled pattern on top of the fudge before cooling.

Refrigerate 2 hours until completely cool and set.

Slice into squares to serve.

Tips and Tricks

Tip: Slice off the edges before cutting into squares for a more uniform look. Then you should probably just go ahead and eat those pieces as a taste test, wink, wink.

Variation

Mix in some chocolate chips to make a peanut butter cup version of fudge. I’m thinking of a backwards Reece’s peanut butter cup, yum!!

How to store leftovers

Store leftovers in an airtight container at room temperature for up to a week.

For longer storage, you can refrigerate the fudge. Make sure it's it's tightly wrapped in plastic wrap to prevent it from drying out or absorbing odors from the refrigerator.
