How to Cut Fudge:

When preparing to serve your fudge, we recommend following these steps to cut your fudge properly.

  • Remove Fudge – When we are ready to cut fudge, I like to remove from the pan. If you lined your pan with parchment, it should be easy to remove.
  • Warm Knife – We like to run our knife under hot water and then dry. A warm knife makes the best cuts.
  • Sharp Knife – Place fudge on a cutting board and with a sharp begin cutting the fudge the size you prefer.
  • Cold Fudge – Make sure you cut the fudge when it is cold. Cold fudge cuts easily so we do not let your fudge get to room temperature.

Frequently Asked Questions

Why is my Peanut Butter Fudge grainy?

Often this happens when fudge is allowed to cool without stirring.

How to store?

Fudge can be stored in an airtight container for up to 1 week. If storing on a tray, cover with plastic wrap.

How to Freeze Fudge?

You can also freeze fudge. This is perfect for holidays or special occasions when you need to make things in advance to save time later. It will last in the freezer up to two months.

If you freeze your fudge, you don’t need to thaw it before serving. It’s actually delicious frozen.

Tips for Easy Peanut Butter Fudge Recipe:

  • Use creamy peanut butter and not natural peanut butter. The recipe will not turn out the same if you try to use natural peanut butter. Natural can separate and this will cause the recipe not to stay together or set.
  • After spraying the pan with cooking spray, don’t skip the part about also lining with parchment paper. It makes it so easy to remove the fudge from the baking dish and clean up is a breeze.
  • Make sure to keep the fudge in an airtight container. This will help the fudge stay nice and fresh.

    This fudge was very easy to make! It also was super delicious and tasted similar to the peanut butter in the Halloween/Easter egg Reese’s (the holiday Reese’s are the best Reese’s in my opinion!) Definitely worth a try!

  4. Stephanie says:

    Why can’t natural peanut butter be used? I make my own peanut butter & want to use it. And it doesn’t separate so that that nasty oil collects on the top.

      You can, It will just have a different texture.
