Key Lime Sugar Cookies

Key Lime Sugar Cookie – a key lime sugar cookie and lime buttercream – A classic Southern pie made into a simple and delicious cookie.

My husband is originally from the South, Louisiana to be exact. Since I’ve met him, I’ve been introduced to crawfish, jambalaya, gumbo, and his favorite… key lime pie. His preferred version comes from his mom, who knows his craving for super bold flavors, rendering this favorite pie a bit too powerful for the rest of us – unless we’re willing to walk around with puckered faces until the citric acid wears off.
These Key Lime Sugar Cookies are my attempt to turn his favorite pie into a cookie. And let me just tell you he loves it and so do I. These cookies turned out to have all the flavor from the inspired pie minus the tartness of the limes that one would expect to have.
These Key Lime Sugar Cookie are incredibly balanced, soft, and addictive as evidenced by my hubby inhaling three before acknowledging my existence. And while I’m not the biggest key lime pie fan, I really love these cookies and devoured almost just as many as my husband.

So looking for a twist on a classic Southern pie or just a cookie that everyone will ewe and awe over – try these Key Lime Sugar Cookies. An easy recipe for a soft, chewy sugar cookie with a punch of lime.

      I would love to see what you come up with, too! I wonder if there is a way to make them gluten free but keep the essence of the recipe? I know my daughter would love to enjoy these with rest of us, because they look divine! :)

    Hi, I’ve never been to your blog, but I found these cookies and tried them. They are really delicious, and the icing recipe is good as well (that usually falls short of the cookie quality in recipes, but not this one). It adds the limey flavor. I made icing designs on them (but with only 1/4 of the icing recipe, we like less in our family). Thank you! I needed a way to use spoiling key limes (you don’t hear that often).

      Thank you so much for taking the time to comment. You made my day! I truly appreciate it and so happy you enjoyed these cookies as much as we have. Hope to see you around the blog more! xo San
