Key Lime Pie Fudge

This post may contain affiliate links. Read our disclosure policy.

It is the last day of fudge week and we are ending with a good one.  A while back, I shared a key lime pie fudge from an etsy shop in a Fab Five post. Well, several of you shared links with me to recipes you can make on your own at home. I decided to give it a try.  So the recipe I ended up with has ingredients I use to make my key lime pie. It inclueds key lime juice, lime zest, and sweetened condensed milk.

The base of the recipe is also very similar to the super easy chocolate fudge recipe I shared the other day.

 It uses less butter so you get a really soft fudge.  Because it is so soft, I recommend keeping this one chilled and serving it chilled.  If you want a firmer set on it like the super easy chocolate fudge just up the amount of butter to 1/4 cup.  I also discovered this fudge needs a good amount of chilling time before you cut it. That will give you pretty looking pieces.

I had several people sample all of the fudge recipes I made for fudge  week. The key lime was the favorite one for several people including my hubby who isn’t a key lime pie fan.

You can always go for no graham cracker crust if you want. However, I would definitely up the butter for a firmer fudge if you do that.  I also thought of a fun way to give it as a gift.  Just buy a pre-made graham cracker crust. Or make the crust in a pie plate instead of a 9 x 9 dish.  Then slice it into wedges just like a pie.  Put it in a cute box and you are set.

Last thing is I recommend is using a good quality white chocolate to make this.  At this time of year, many grocery stores sell blocks of chocolate. They packages that have cut up chunks of large bars of chocolate.
Here are a few other fudge recipes I have if you still want more – rocky road fudge and pumpkin fudge.
