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.

    Oh my gosh. As usual – this looks freaking amazing. My son would LOVE this! And if it makes you feel any better – whenever I complain about anything, my husband always tells me, in a very monotone voice, “You better get your affairs in order. ”
    And he’s a doctor.
    Humph.

  2. Nothing like watching a medical show where someone goes into the ER for a headache and ends ups dead by the end of the show. Yeah, I had to stop watching those shows too!

    This fudge looks amazing! Keep the goodness coming! Love your “That’s What She Said” blog too. You guys crack me up!!!

  3. Aimee @ ShugarySweets

    I made key lime fudge last year, and you’re right, it’s crack-fudge! This makes me want to make some right now. Love that citrus!

  4. I had a brain tumor (mostly) removed last November and I can assure you that I did not become a genius. Nor do I bear any resemblance to John Travolta. Possibly one of the other sweathogs, though. 🙂

  5. I cannot watch ANY medical show for fear, I too, have that condition. You are not alone in your paranoia. Mine became ridiculous once I had kids! But nothing like some Spring-y fudge to put you in a brighter disposition! Thanks for sharing it!

    Don’t get me started on self diagnosis. I have brain tumors REGULARLY. Stupid Derek Shepard.

    This fudge needs to happen in my life NOW.

  7. Also I once convinced myself I had a prostate and then of course prostate cancer because webmd told me it was a possibility.
