This delicious peanut butter fudge is made with a boiled mixture of sugar and milk, marshmallow creme, peanut butter, and vanilla. It’s a creamy fudge with loads of peanut butter flavor. I add about 1 cup of chopped walnuts, but you can feel free to omit the nuts. Or add chopped peanuts or pecans to the fudge mixture.

What if I don’t have a candy thermometer?

You can get a pretty good idea of temperature by testing small amounts of the candy mixture in cold water. Here’s how:

  • Drop about 1/4 teaspoon of the mixture in cold water.
  • With your fingers, coax the candy together form a soft ball. If it doesn’t form a ball, continue cooking and check again after a few minutes.
  • The soft ball should form easily, and when lifted from the water, it should flatten slightly.

Tips

  • Before making the fudge, grease the pan lightly and line it with buttered plastic wrap or foil. Leave some overhang on each side of the pan. This will make it easier to lift the whole block of fudge out of the pan when it’s time to cut and serve.
  • Corn syrup helps discourage crystallization and graininess in fudge. If you don’t have corn syrup, add 1/4 teaspoon of cream of tartar. Or wash down the sides of the pan with a pastry brush dipped in hot water until the sugar has completely dissolved.
