Frosted Lime Sugar Cookies are sweet and tart cookies topped with lime buttercream frosting. A twist on the classic Southern pie became a simple and delicious cookie recipe.

Lime sugar cookies are soft and chewy with a dollop of buttercream frosting to dress them up. They’re as sweet as the pie that inspired them!

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 tell you he loves them, and so do I. These cookies turned out to have all the lime flavor from the inspired pie minus the extreme tartness of the limes that one would expect to have.

They are incredibly balanced, soft, and addictive, as evidenced by my hubby inhaling three before acknowledging my existence. While I’m not the most significant critical lime pie fan, I love these lime cookies and devoured almost just as many as my husband.

Why key limes make great desserts

  • Key limes are known for their unique flavor and acidity, which makes them excellent for creating delicious desserts. Here are a few reasons why key limes are great for desserts.
  • The flavor of key limes differs from regular limes because they are more intense and aromatic, giving desserts a refreshing and vibrant taste. Their tart and tangy flavor is distinct and adds a special touch to various sweet treats.
  • Key limes have high acidity, which is beneficial in desserts as it balances the sweetness. The tartness effectively complements rich ingredients like cream and butter, resulting in a more complete flavor. In addition, the zesty and vivid flavor note provides an extra boost to the taste.
  • Key limes can be used to make various desserts, such as pies, tarts, bars, cakes, cookies, and more. They go well with ingredients like graham cracker crusts, whipped cream, meringue, coconut, and chocolate, allowing for various dessert options.

Cookie Baking Tips!

Can you freeze sugar cookies?

All cookies can be frozen, but it is best to wrap them individually and only do this once they have cooled completely. Another way to freeze them is to stack them in layers in a Ziplock or container, separating the layers using parchment paper. I love individually wrapping them, as I feel they taste better. Do not freeze after frosting.

How long will cookies stay fresh in an airtight container?

Properly stored, freshly baked cookies will last for about 2 to 3 weeks at average room temperature in an airtight container. It is best to frost before serving.

Can you freeze the dough?

This cookie dough can be easily frozen, but it is best if you portion the dough beforehand. Scoop the cookies like you were going to bake them and place them on parchment paper. Then, wrap the parchment paper in plastic wrap or store them in an airtight container.

Before you bake, preheat the oven, following the cookie recipe’s suggested temperature. Place the cookies on a baking sheet lined with parchment paper, 2 inches apart. The only thing you will need to change is adding an extra 1-2 minutes to the baking time for the frozen dough.

    2. 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! 🙂

    3. Can you give me more exact measurements for the lime juice? I just juiced 8 key limes and then read I was to use the juice of one lime. Whoops!
