3 ingredient peanut butter fudge is rich, creamy and delicious. Best of all, it is super simple to make. You don’t need a candy thermometer, just a microwave or a double boiler.

If you are a peanut butter lover, this is the treat for you. It takes just a few minutes to put together and the resulting fudge taste great!

This microwave peanut butter fudge is beyond easy to make. It is super creamy, not at all grainy and perfectly peanut buttery.

A lot of fudge recipes use sweetened condensed milk, white chocolate chips and peanut butter. We use peanut butter chips instead to give the fudge even more fabulous peanut butter flavor.

Ingredients

Sweetened condensed milk is the rich creamy base for this fudge. The liquid gold is a good start towards something delicious in this super easy recipe.

For the peanut butter, you will want to use a classic jar of peanut butter. I wouldn’t use homemade or the natural peanut butter that you have to stir.

You want to make sure it incorporates nicely and the homogenous peanut butter will mix in nicely without worrying about the oil rising to the top. Plus it adds a little extra salt and sugar to the mix.

Now add a bag of peanut butter chips. They help the mixture firm up and give you that melt in your mouth fudge texture.

Just melt everything together in a microwaveable bowl or a double boiler and you are well on your way to a tasty treat. If using the microwave, cook the mixture in short bursts to keep from scorching it. As soon as the chips are able to be stirred smooth, it is done cooking.

If you use a double boiler, just be sure to keep the water and steam out of the fudge mixture. Be sure to wipe the bottom of the bowl before you pour it into the prepared pan.

Tips and Tricks

Lining your pan with foil is not absolutely necessary, but it allows you to lift out the block of fudge to cut it into cleaner squares. If you want to serve it straight from the fan, feel free to skip this step.

The easiest way to line the pan with foil is to smooth it over the bottom of the pan first. Then turn pan over, and gently fit shaped foil into pan.

When fudge is cooled completely, lift out of pan by the foil. Then just peel off the foil and cut into pieces.

Feel free to add chopped nuts or candy, such as peanut butter cups, to the mixture before spreading in pan. We love making chocolate Easter egg Peanut butter fudge, but chunks of Reese’s peanut butter cups would be amazing as well.

Add a festive touch to this peanut butter fudge by sprinkling with holiday-colored sprinkles before the fudge sets. Or add a sprinkling of coarse sea salt on top of the fudge to enhance the sweet and salty finish.

Pour the fudge directly into cookie cutters or cute tins to make an easy gift. Or add it to Christmas cookie trays as a smooth peanut butter candy addition.

There are so many different ways to take this easy peanut butter fudge recipe and turn it into something fabulous by adding a few simple optional ingredients. Though I think it is hard to beat the smooth texture of the original recipe, in my opinion it is the perfect treat.

Storing your fudge

Fudge should be stored in an airtight container. It holds well on the counter at room temperature and will last there for at least a week.

For longer storage, put your airtight container in the refrigerator for up to 3 weeks.

We like a nice creamy peanut butter fudge, so we use creamy peanut butter. If you like a little bit of texture, feel free to try crunchy peanut butter.
Use a standard peanut butter, not the kind you have to stir before using.
