Fudge is one of my favorite holiday treats. When I was growing up, my grandma would spend endless hours in the kitchen making peanut clusters, fudge, divinity, peanut brittle and cookies.

Working from home with three young girls doesn’t exactly give me enough time to do the same, so I’m simplifying. I made foolproof slow cooker fudge and I’m so excited to share it with you!

I am a fan of all the sweet treats for the holidays. (Well… all year long but that’s a story for another day!) There’s just something about the fragrance, the warm kitchen, and the traditions that I love sharing with my little girls.

It takes just a few minutes to make this white chocolate fudge in your slow cooker. You’ll be so glad you did!

Frequently Asked Questions

Why isn’t my fudge hardening?

This is generally because your fudge wasn’t cooked to a high enough temperature. Depending on your crockpot, it could take up to 1.5 hours to hit a high enough point!
To ensure you’re getting it hot enough to set up, buy a candy thermometer. The ideal temperature for fudge is generally between 237 to 239 °F.

Does fudge need to be refrigerated to harden?

Crockpot fudge can benefit from time in the fridge to fully set up if you don’t feel it’s quite hard enough! Place it in your fridge (in your lined or grease pan) for up to two hours to harden a little further.

Tips

  • “Why isn’t my fudge setting up properly?” In most cases, your fudge mixture needs be cooked a little longer, to a higher final temperature. If this happens to your fudge, you can reheat it with a little more evaporated milk, bringing it back to a boil.
  • All crockpots are different. If you feel like your melted fudge mixture isn’t getting hot enough, move it to the stove!
  • If you grease your pan, allow it to sit five minutes before cutting and serving for easy removal.
  • My favorite baking spray makes it so easy!
  • Another option for easy fudge removal is to line your baking pan with parchment or wax paper, with some extra hanging over the sides, make it so easy to pop out.
  • Worried about getting the temperature right? Try a candy thermometer to ensure it’s hot enough, if you don’t want to wait for the skimming process.

How to Store

  • At Room Temperature – store in an airtight container for up to 2-3 weeks. Fudge is best stored at room temperature, as the refrigerator can create moisture and condensation which will lead to separation.
  • Refrigerate – You can refrigerate your white chocolate fudge for up to four weeks. Wrap it airtight because it can dry out faster in the cold air.
  • Freeze – Cut into slices and wrap with aluminum foil to keep it airtight before bagging. Freeze for up to six months.

How to Serve

  • For the holidays, make it festive with sprinkles! You can mix them in while the mixture is warm, just note that your fudge will pick up a little of the pretty color, but swirl beautifully!
  • Or, you can top the White Chocolate Fudge with sprinkles just after you pour it into your dish.
