Peanut Butter Fudge Ingredietns
  • Peanut Butter – A creamy store-bought peanut butter works great for this recipe or Jif Peanut Butter was what my grandma used. You could possibly use a crunchy peanut butter but, I have never tried it with nuts.
  • REAL Butter – Salted or unsalted butter will work. We typically have salted butter in our house so, that is what we used for this recipe. Do not use something like margarine.
  • Corn Syrup
  • Sugar – NOT Confectioners sugar (powdered sugar) like other fudge recipes use.
  • Evaporated Milk – NOT sweetened condensed milk.
  • Vanilla

Of course, you could always use Homemade Peanut Butter for this fudge recipe too!

How to make Easy Peanut Butter Fudge

Fudge ingredients in a pan.

Once you’ve gotten all your ingredients around, making Homemade Peanut Butter Fudge is quite quick and easy. To make a batch of this fudge you will want to have a candy thermometer or take a peak at this post on What Soft Ball Stage is.

  1. Mix Sugar, Corn Syrup and Evaporated milk in large pan and cook over medium heat. Sir occasionally. Mixture will begin boiling. If it boils close to the top of the pan, reduce the heat slightly.
  2. Continue cooking until mixture reaches soft ball stage (230-240 degrees). You can test for this by seeing if a small amount of the mixture forms a ball while in cold water, but flattens once removed from the water.
  3. When it reaches Soft-Ball stage, remove from heat. Take butter and grease inside of glass baking dish. Add remainder of butter and vanilla extract and stir until butter is melted and incorporated. Add peanut butter and continue stirring until mixture start to lose its’ sheen. Then pour into buttered baking dish and allow to cool.

Substitutions

Can’t find the ingredients for our easy fudge recipe? Here are a couple substitutions you can try:

  • Evaporated Milk – Since evaporated milk is just normal milk that’s had some of the water content cooked out, there are a few easy substitutes. Try using normal whole milk, half-and-half, heavy cream, or some combination of those 3 as a substitute. Note that evaporated milk is a bit creamier than normal milk since some of the water is evaporated, so we’d definitely recommend incorporating some cream.
  • Corn Syrup – We’ve always made our Old Fashioned Peanut Butter Fudge with corn syrup but there’s other options. Instead of corn syrup, you could also use a brown sugar- either light brown sugar or dark brown sugar, depending on how much of that molasses flavor you want in your fudge.

Variations

Looking for ways to change this recipe up? Here are a couple of ideas for making the homemade fudge a bit different:

  • Loaded Peanut Butter Fudge – We normally make our Peanut Butter Fudge with a creamy peanut butter, but maybe you want a little crunch in yours? Outside of using a crunchy peanut butter, you could also mix in some crushed peanuts or any other sort of crushed nuts.
  • Other Nut Butter Fudge Recipes – If you’ve ever looked around your grocery store, you’ve probably noticed all sorts of different nut butters. So many of these could work in our fudge recipe: try making almond butter fudge or cashew butter fudge next!

Storage / Freezing

Storage: Once your fudge is made let it cool on your countertop. If you are in a pinch you could place in the fridge for about 30 minutes. Fudge is best if enjoyed at room temperature. Store the fudge in the fridge for up to 2 weeks in an air-tight container or wrap in plastic wrap. I personally add small piece of parchment paper between layers.

Freezing: You can also freeze this old fashion peanut butter fudge if you need more long-term storage. You will want to wrap in an air-tight container before placing in the freezer. It will last for about 2-3 months when frozen.

Top tip

Instead of buttering your dish, consider lining the pan with parchment paper. This makes it easy to remove the peanut butter fudge from the pan.

  3. I love a good fudge, made many in my day, although never with peanut butter added to the mix, so will have to give this a try.
    Thank you for sharing your links with us at #271 SSPS Linky. See you again next week.

  4. I have a good friend who does not like peanut butter fudge with marshmallow in it so last year for Christmas I made your fudge for her and she loved it, so this year I wanted to make it again for her but discovered I did not save it so I had to do a lot of searching to find your recipe again. I made her the fudge, she loves it. I have made sure I saved your recipe this time. Thank you so much for sharing this.
