I’m not a huge fan of pie.  A good berry pie certainly has a place in my heart, but to be frank, I tend to snub my nose at any other flavor of pie.  I just do not gravitate towards cake’s flakey cousin.  Pie is a second rate dessert in my humble opinion.  It’s good in a pinch but only if it’s cherry or berry pie.  Otherwise, a slice is not worth the calories.

The only pie that actually comes close to being in the top tier of my dessert classification is key lime pie.  Boy do I love a good key lime pie.  Nothing makes me smile quite like a key lime pie that is so tart your mouth puckers upon first bite.  It has to be cool, creamy and smooth.  And it must be made with fresh, tangy key limes.  That kind of pie is worth any amount of calories!

These sugar cookies have everything I love about key lime pie.  They are delicately sweet but have an abundance of key lime flavor.  The sugar cookies are so soft and tender and topped with the creamiest frosting.  Each bite practically melts your mouth.  The citrusy green flecks of fresh key lime zest peak out from both the sweet frosting and the buttery sugar cookies for a taste reminiscent of a tartly good key lime pie!

The only real issue I see with these key lime sugar cookies is that they are so irresistably good, you cannot stop eating them!  If you make them bite sized as I did, then self control just goes right out the window!  Trust me, I speak from experience.

If you are a fan of key lime pie, then my friends, these sugar cookies are for YOU!

    These look so good and I love tart and key lime pie! I’m not a big baker, why is shortening added to the buttercream frosting?

    • It’s personal preference, I like to cut the buttery taste. I like the way shortening sets up when I frost the cookies too.
