Peanut Butter Fudge Recipe

This peanut butter fudge is a favorite in our home - my husband taught me to make it when we were first got together over 8 years ago!

Over the years it is still our go-to recipe for peanut butter fudge because it's rich, creamy, and smooth.  Make sure to check out my video below for my Peanut Butter Fudge Recipe - it's surprisingly quick and easy!


Making the Fudge

You can either grease a dish with butter so the fudge won't stick or you can line the dish with aluminum foil.  The aluminum foil makes for easier cleanup and it's easier to take out of the dish and cut.

After mixing the ½ stick of butter, 1 can evaporated milk, and the 4 cups of sugar make sure not to burn the mixture or overheat. Simply melt all the ingredients down in the pot.

While the ingredients are melting, combine the rest of the ingredients in a large bowl.

After combining both mixtures together, make sure to smooth out all lumps to create a consistent fudge taste throughout the batch.

The trick to this peanut butter fudge is the soft ball stage. Once the fudge forms a ball when a drip is placed in a glass of cool water, it's ready.  Of course, you can always use a candy thermometer - I've just never had one 🙂

Once it is done, make sure to chill at least 4 hours (I like to let it chill overnight).  That it has time to set.  It's worth the wait.  The result is a delicious, creamy, tasty treat.

This recipe makes up a large batch so it's perfect to cut into small squares and give as gifts in bags, boxes, or on plates.

I'm so confused. Why does the video say condensed milk and the recipe have evaporated? I already bought the ingredients. I hope this turns out okay!

Hi Meghan, It is condensed milk! I have updated the recipe card to reflect the correct changes.
