Once you try this fudge recipe, you will never want to make it any other way. I have tried making my grandma’s old fashioned peanut butter fudge recipe many, many times only to be disappointed that it didn’t turn out the way I remember her fudge, so creamy and so good. Mine always turned out gritty, crumbly and overcooked. Even using a candy thermometer, I was never happy with the end result. This recipe doesn’t have a boil time or temperature to reach, and doesn’t use granulated sugar so no more gritty, overcooked texture.
This fudge melts in your mouth and only takes just a few minutes to make. Made with the same ingredients as my peanut butter ball recipe, it is essentially no fail!

Storing Peanut Butter Fudge
There is nothing more nostalgic than a Christmas tin full of peanut butter fudge. My grandma’s would always have a tin of their famous fudge on the dessert table for Christmas and in my opinion, there is no better way to store it! You can keep the fudge in an airtight container on the counter for 1-2 weeks. Layer the fudge with parchment between each layer.
Fudge can be stored in the fridge for 2-3 weeks and in the freezer for up to 3 months in an airtight freezer safe container. Be sure to layer with parchment and thaw in fridge before serving.
