Coconut Key Lime Bars


I am a Muppet Show baby.  I watched it faithfully when I was a kid.  Truth is, there wasn’t much else on.  My favorite characters were Beaker and the Swedish Chef.  I had a soft spot for their unintelligible speech.  I wasn’t into dialogue back then.  What stands out for me most from those Muppet show days (other than John Denver) was the skit where Kermit the Frog has a stomach ache.  Apparently if you mix lime and coconut and drink it all up-you get a terribly upset stomach.  To this day, I love that song!  I disagree, however, with the notion that one cannot combine coconut and lime.  That’s simply NOT true.

Coconut Key Lime Bars

I combine coconut and lime all the time.  Take these cookies for example.  Coconut+key lime+ white chocolate=a crunchy, tropical deliciousness= happy belly.   Ok, so technically limes and key limes are not the same things.  Perhaps key limes are a slightly more subtle citrus and  therefore is easier on the digestive tract?    All I know is I love coconut, I love key lime, why not combine the two?
Coconut Key Lime Bars
Most people think of pie when they think of key limes.  I do love a good key lime pie.  But I love discovering other ways to bake with my favorite zesty fruit.   These bars are so easy, especially since the base is your favorite yellow cake mix.   The hardest part baking these bars was juicing those slippery little key limes.  I found myself pursing my lips every time I squeezed a lime.  And the more I thought about it, the more I pursed.   I guess you had to be here.  You could use bottled key lime juice, but I don’t recommend it.  I think the fresh juice, well, tastes fresher!
So there you have it, I put the lime in the coconut and I ate it all up!

  1. I’m one of THE biggest key lime fans on the planet! I never use bottled — I buy them whenever I see them, juice them, and freeze it to use whenever a craving strikes! Coconut and lime is a favorite flavor combo — I just posted a coconut-lime baked donut this week! Love the sound of these bars!

    • I never thought about freezing the juice! That is a fantastic idea!

  2. These look amazing! Lime and Coconut are pretty much my fav combo! YUMMY!

  3. I love lemon bars, so I’m thinking these are a delightful twist on those! And I totally agree, lime and coconut go together perfectly well. Hence the song, “Put the lime in the co-co-nut”! LOL

    • You will love these if you love lemon bars! The key lime is pretty mild.
