Variation ideas:

  • Nut Butter. Peanut butter can be substituted with another type of nut butter.
  • Crunchy Peanut Butter. Use crunchy peanut butter instead of creamy for a different texture in the fudge. It will not be as smooth but gives it a new flavor in the peanut butter layer.
  • Frosting. Substitute vanilla frosting for the chocolate frosting to make Peanut Butter fudge. This tastes so amazing.
  • Nuts. Add nuts to the fudge mixture either on top or mixed in. Walnuts or pecans would be delicious in this recipe.
  • Mix-ins. You can add candy or add-ins to change the flavor. Mini M&M’s, reece’s pieces, mini marshmallows and peanut butter chips would all be delicious.
  • Extract. You can add 1 teaspoon vanilla extract to the fudge if you prefer.
  • Topping. Sprinkle the top of the fudge with sprinkles, nuts or candy. Try different color sprinkles for holidays, birthday parties and special occasions during the year.
  • Shapes. Use cookie cutters to cut the fudge into shapes instead of slicing into bars. You can do hearts, stars, Christmas trees or anything you like.

Pro Tips

  • If you prefer fudge to be harder, put in the freezer for 30 minutes. This should help it to harden.
  • Fudge is best enjoyed at room temperature. I would suggest taking it out of the fridge a few minutes before serving.
  • Don’t try to cut the fudge into squares too early. It needs time to set or it will be hard to cut and messy.
  • Try using a plastic knife to cut the fudge into squares. It will give you nice clean lines. Make sure to wipe the knife with a napkin if any residue remains so all the slices will be clean.
  • You can cut fudge into any size you prefer. It is so sweet and rich so a little goes a long way. I like to cut the fudge into very small pieces.


How to store fudge?

Place inside an airtight container in the fridge. I also like to use parchment paper in between the fudge to prevent it from sticking.

It will keep up to a week in the refrigerator. When you are ready to serve this, allow the fudge to come to room temperature before eating.

Can you freeze fudge?

Fudge can easily be frozen if you need to make this in advance. I love doing this for holidays, parties and more.

Just put the fudge inside an airtight container and put in the freezer. I also like to use the wax paper in between the layers when freezing.
You can freeze fudge up to 3 months in the freezer. It is best to let this thaw overnight in the fridge when ready to serve.

I often make extra to have some for the freezer. It is perfect when you need a last minute gift.

It is also really nice when you want a little something sweet. You can grab a few squares from the freezer.

    Thanks for the recipe, Carrie. I just have one question. If the peanut butter is combined with the chocolate, why doesn’t it make the fudge look lighter in color. It’s not that important, just wondering. Thanks.

    1. Carrie says:

      It is just the peanut butter/ chocolate ratio. If there was more peanut butter, it would lightening it up more.
