I have had many interesting experiences with candy making.  I have cooled fudge so fast that it was literally frozen to the sides of my bowl.  I have cooked caramels too hot so that when I poured them into my pan, they became rock hard, there was no way to get them out and I had to throw the entire pan away!  I have tried many different candy thermometers, testing candy for doneness using the “ice water test” and wanted to kick and scream once or twice when my fudge crystallized and was as enjoyable to eat as sand.  However, through my years of trial and error, I have had some successes and learned a few tips too.

The last couple of years have been more successful for me and so this year I was anxious to try a new fudge variation.  This Peanut Butter Cup Fudge is a Reese’s lover’s dream.  It is chocolatey and sweet, but also has robust peanut butter flavor.  Also, this was my first time trying this recipe and it was successful so that is a win in my book.

Here are a few tips that have helped me with making fudge:

  • Only stir the hot mixture at the beginning until the sugar as dissolved.  After that, you can stir it a few times, but not constantly.
  • When the fudge is cooling (before you beat it) DO NOT TOUCH IT!  Just set a timer for 10 minutes and tie your hands behind your back until that timer goes off.
  • Trust your instincts.  If the recipe says beat until “no longer glossy”, trust your eyes and as soon as the fudge looses it’s sheen, turn that mixer off and get it into a well-buttered pan.
  • Fudge freezes very well.  I wrap mine in wax paper, place it into a resealable freezer bag and take out small amounts when I want to serve it.  Just take it out of the freezer an hour before you want to enjoy it.
  • Be patient.  The disasters that happen in the kitchen make for good stories and it makes the successes that much sweeter :).


Peanut Butter Cup Fudge

Prep Time: 1 hour, 30 minutes

Cook Time: 20 minutes

Dense chocolatey fudge with the irresistible flavor of peanut butter is topped with chopped peanut butter cups
