Key Lime Fudge Bars

All the flavors of a bright and zesty key lime pie, in the form of homemade fudge! This recipe for Key Lime Fudge Bars is seriously citrusy, and so addictive!

Two key lime fudge bars on a square white plate.

In the last year or so I have developed an annoying tendency.

I have become one of those people who is convinced they have a life-threatening illness.

With every headache I convince myself that I have a brain tumor and wonder when my tumor  grows if I will become a major genius like John Travolta did in Phenomenon.

With every ache in my knee I am doing research online on who is the best knee replacement surgeon in my area.  Or really the whole country because no expense can be spared when I am in need of a life changing surgery.

My knuckles have been aching lately and I have convinced myself that I have Rheumatoid Arthritis.  My husband laughed at me and said yeah, you’re 36…sometimes things just start to ache a little.

He doesn’t feed into my paranoia.  Instead of playing along and acting concerned he just tells me to go for a walk and drink a glass of water.  Like fresh air and H2O are gonna solve my problems.  Ridiculous.

Watching Grey’s Anatomy also does not help, because there are some crazy medical situations that arise on that show only fueling my internal self diagnosis arsenal.

So the other day to get my mind off the cutting-edge eyeball transplant surgery that I will most certainly need, I decided to make fudge.

Of the key lime variety.

At least my brain is working.

I will warn you, though.  This stuff is basically crack-fudge.  I’m not kidding.  The chance of you having high blood sugar after making and inevitable eating the entire pan is imminent.  Real talk.

First make a yummy shortbread crust.  Kind of unconventional for fudge, but trust me on this.

A lined baking pan filled with a crumb crust.

Then melt some white chocolate.  I always use a double boiler for white chocolate because I am not a good microwaver.

White chocolate chips in a glass bowl.

While that’s melting, zest a few limes…

Two limes that have had their zest removed.

Then mix your melted chips, sweetened condensed milk and Key Lime juice together. Stir in your zest…

Lime zest is added into a bowl of fudge ingredients.

Now, if you are feeling fancy, reserve 1/4 cup of the white chocolate mix and tint it green to swirl in to the fudge.

Spread the uncolored mixture evenly over the crust and then swirl in the tinted.

Pop it in the fridge and let it set up for about 2-3 hours.

Cut it up when you’re ready to serve…

Out of control good.  I wouldn’t steer you wrong.

  1. This looks scrumptious and I cannot wait to make it. I will need to find gluten free shortbread cookies, first, though. In that vein, I am curious as to how this would turn out using other citrus fruits. imagine, lemon fudge, orange fudge, grapefruit fudge……..I may give those a try after I make the lime version……I LOVE THIS WEBSITE!!

    yum, I must try this. And I always think the worst when I am sick. And lord help me when I have surgery, or in the hospital. Last time when I had a twisted bowel I was thinking open surgery and weeks of recovery. I was out in a few days, no surgery just lots of pain meds, but in my mind I was going to be in for at least a week, miss Christmas and you know, the worst. It’s just in our nature I guess. Oh and I cannot microwave white chocolate to save my life, I cannot figure out how to get the power to 50% ( I could look at the manual, but I never think of that when I am doing it) But I am way to lazy to use a double boiler, so lumpy chocolate it is for me.

    Whooooaaaaa- this looks super yummy. Isn’t the internet a great thing… for googling every ache and pain we have??? I totally diagnosed that I had gallstones that way… but I too am obsessed with the idea that something else is going on in every nook and cranny of my body!!

  4. This is too funny because I am the same way. I web md every little ailment and I always have either cancer or a stroke. Then I freak out even more because I’m sure I will die and leave my kids without a mom! My husband doesn’t get it…he just laughs at me even more:-) I’m pretty sure this awesome fudge is the cure all for my “sicknesses”!!!!
