This Old Fashioned Peanut Butter Fudge recipe is packed with peanut butter flavor! It’s smooth and creamy, and only has five ingredients.
Nothing says the holidays like a batch of fudge! This Old Fashioned Peanut Butter Fudge is a recipe I’ve adapted from a 1976 Pennsylvania church cookbook.
The secret to this foolproof fudge recipe is marshmallow creme (a.k.a. marshmallow fluff). It gets stirred in with the peanut butter to make the creamiest fudge.
What I love about this recipe is that it only has 5 ingredients. It’s a truly easy way to make homemade candy for the holidays, and this batch will feed a crowd. I love giving it away to friends and neighbors.

Top tips
- You’ll need a candy thermometer for this recipe. Fudge can be temperamental, but a thermometer will ensure the best results.
- Don’t use natural peanut butter (the drippy kind) for this recipe. Use a regular variety of peanut butter like Skippy or Jif.
- I recommend lining the 13×9-inch pan with parchment paper. This way, you can just lift out the fudge for easier slicing.
Ingredients
- We’ll cook sugar and evaporated milk (NOT sweetened condensed milk) together to create the base of the fudge.
- Use a regular peanut butter, like Skippy or Jif (NOT a drippy kind and NOT a natural variety).
- Marshmallow creme makes for the creamiest fudge!
- Salt balances out all the sweetness.
How to make old fashioned peanut butter fudge
Place the sugar and evaporated milk in a large, heavy-bottomed saucepan. Place the pan over medium heat.
Bring the mixture to a rolling boil, then reduce the heat slightly and cook until the mixture reaches 235°F on a candy thermometer, about 8–12 minutes.
Watch the mixture closely, as it will have a propensity to boil over if the heat is too high.
Once it reaches 235°F, immediately remove it from the heat. Stir in the peanut butter, followed by the marshmallow creme, until smooth.
Pour the mixture into a 13×9-inch dish lined with parchment paper and let cool completely. This will take about 4 hours at room temperature or 2 hours in the refrigerator.
Once the peanut butter fudge is completely cool and set, lift it out of the pan using the parchment paper, and slice into 1-inch or 1½-inch squares.
Tips for slicing the fudge
To get clean cuts each time, run a knife under hot water and wipe dry with a kitchen towel. Slice the fudge.
As the knife gets little bits of fudge on it, repeat the process of running it under hot water and wiping dry. This will get you the nicest looking pieces of fudge.
Make it ahead
Old Fashioned Peanut Butter Fudge is great for making ahead! Store it in a covered container either at room temperature or in the refrigerator.
For best results, serve it within one week of making it. It’ll keep in the fridge for several weeks, but may dry out slightly as the weeks go on.
How to store fudge
Storage depends on how you like to enjoy the fudge! If you prefer a softer fudge, keep it at room temperature. If you like a slightly firmer texture, keep it in the refrigerator.
Either way, store it in a covered dish, with pieces of wax paper or parchment paper in between layers so it doesn’t stick together.
You can also freeze fudge for up to 3 months. Wrap it well in plastic wrap before transferring to a covered dish or freezer bag for freezing.
