4 Ingredient Peanut Butter Fudge

So before my friends stage an intervention over my love of all things fudge and specifically peanut butter fudge I HAVE to share this recent version with you.

It really doesn’t get much easier than my classic four-ingredient fudge recipe. Butter, peanut butter, powdered sugar and a dash of vanilla. For ease of making and amazing richness, you will be hard-pressed to find a better one.

While I have been making this specific peanut butter fudge recipe for over 10 years now, it is fun to mix it up sometimes with other ingredients. Hence the Oreos.

The beauty of this 4 ingredient peanut butter fudge recipe is not only is it easy but it is easy to scale. Just want a small batch, cut it in half. Making treats to share during the holidays go ahead and double it. It is not a finicky recipe in that regard.

Side note – if you watch the above video for the peanut butter fudge it was made with a HALF recipe for this fudge. The recipe can easily be halved or doubled or multiplied however you like.

As pictured in the video, the fudge should be firm and almost crumbly when mixed together and pressed into the pan. It should not be liquid at all.

This simple four-ingredient recipe is made with real butter. (5 ingredients with the Oreos.) The results can’t be guaranteed if you choose to substitute margarine or another butter alternative. The fudge might be greasy and might not even set up without the original ingredients.

Microwave Directions

Combine the peanut butter, butter, and vanilla in a glass bowl and melt in the microwave for 90 seconds. Stir to combine, it should come together very quickly and be smooth and creamy. Slowly add the powdered sugar a cup or so at a time. Stir to combine thoroughly.
Chop the Oreos into quarters and fold into the fudge, reserving a few for on top. Use your hands if necessary to mix the cookies through the fudge.
Grease an 8-9″ pan with butter or line with parchment. Transfer the fudge mixture to the pan and press into the pan. Top with remaining Oreos. Chill for at least 4 hours before cutting. Store in an airtight container in the refrigerator.

Stovetop Directions

Best Fudge Recipes

You can’t ever have too many fudge recipes, especially during the holidays.

White Chocolate Pretzel Fudge is a salty, sweet, and crunchy treat that I love including on candy and cookie platters to share with friends. Chocolate Covered Oreo Fudge was inspired by the fudge-covered Oreos that became popular a couple of years ago and we all found it so much better than anything from a box.

Peppermint Marshmallow Fudge practically sings with Christmas cheer. It’s the ultimate holiday fudge recipe but my kids enjoyed it so much that I can see myself making it anytime the craving hits even if it’s the middle of July!

For something a little different on your holiday baking list, how about trying this M&M White Chocolate Fudge or this Cookies and Cream Fudge? I think white chocolate and vanilla fudge varieties look so pretty, especially with bits of candy or cookies mixed in!
