Peanut Butter Fudge

I have gotten quite a few requests for peanut butter fudge, so it was time to finally make some! With the holidays here, the more fudge varieties, the merrier! I love to give fudge as gifts, making the pieces into different shapes. It’s also nice to have fudge around for a sweet treat for your guests and yourself! I used creamy peanut butter for my Peanut Butter Fudge, but go ahead and try chunky peanut butter for an extra crunch!

What is a Candy Thermometer?

A candy thermometer, also known as a deep-fry thermometer or sugar thermometer, is used to measure the temperature of a sugar solution. It is definitely an important tool to have when making candy. Just like using a meat thermometer is important for the perfectly cooked meat and measuring cups and spoons are important for measuring ingredients, a candy thermometer has its place in the baking world, for sure! You can find them in most grocery stores and houseware stores. When you use it, just make sure you don’t immerse the thermometer directly into boiling water or let the bulb hit the bottom of the pan. It really is a game-changer, or should I say candy-changer, for your future sugary recipes.

How do you harden Fudge?

Allowing fudge to come to room temperature will solidify it and make it easy to handle. You can also pop it into the refrigerator for a couple of hours or even the freezer for about 30 minutes. Fudge is best consumed at room temperature though, so be sure to take it out a few minutes before you want to eat it.

How to Store Peanut Butter Fudge

If you are planning on eating it within 2 weeks, you can store the fudge in an airtight container. I like to separate the layers with parchment or wax paper. You can also store fudge in the refrigerator for a few weeks. Again, an airtight container with separated layers is best. If you need longer storage, like months, the freezer is the best option. First, I like to tightly wrap the fudge with plastic wrap. Then I place it in an airtight container or freezer-safe plastic bag. Be sure to write the date on it!
