These buttery, flaky, and crumbly key lime cookie balls are incredibly easy to make, eat, and share. And they are the perfect afternoon treat.

And like the Chai Spiced Cookies, these cookies are just as easy to prepare. You’ll just need five simple ingredients to make these wonderfully sweet and lightly tangy cookies.

The subtly tart lime flavors are balanced with a sweet coating of powdered sugar.

During the fall and winter months, I love making lots of fun cookies. Just like the Strudel Cookies, the Key Lime Cookies are great because they also work great as a summer cookie recipe.

And if you make the key lime cookies in the summer, enjoy them with some of your favorite delicious cold iced tea.

These cookies are so easy to make, chances are you don’t even have to go shopping.

Tips and Tricks

LIMES. Finding good, juice, and properly ripened limes are key for making great key lime cookies.

POWDERED SUGAR. Did you know that powdered sugar, confectioner’s sugar, and icing sugar all the same thing?

I don’t have powdered sugar. can I use regular sugar instead?

For this recipe, you need powdered sugar. But what happens if you don’t have any powdered sugar in your pantry. Don’t panic.

You can easily make your own powdered sugar!

How To Make Powdered Sugar

Use a high-speed blender like the Nutribullet or a small food processor. Combine one cup of cane sugar with 1 teaspoon of cornstarch and blend until the sugar dissolves into a fine powder.

Add a small amount of cornstarch (tapioca or potato starch works, too) to prevent the sugar from clumping.

Ingredients

Instructions

  • Preheat the oven to 350° Fahrenheit. Cover a large baking sheet with parchment paper and set aside.
  • Blend butter and powdered sugar in a stand mixer (*see notes) at medium speed until the texture is fluffy.
  • Add lime juice and lime zest and combine well.
  • Combine corn starch and flour. While the mixer is running, begin to slowly add the flour/cornstarch mixture to the dough.
  • Once everything is well combined, remove the dough and shape with your hands in a large ball.
  • Chill for 30 minutes
  • Cut the dough in half and form little 1-inch dough balls. Place the dough balls onto the baking sheet and bake for 20 minutes.
  • Place the hot cookies on a cooling rack and dust with powdered sugar.

Notes

*If you don’t own a stand mixer you can use a hand mixer instead. I have never tried it, but I think you could also use a food processor to blend your ingredients. 
**Use the flat beater attachment if you are using a kitchenaid. 
If you are wondering if you can make the key lime cookies ahead of time. The answer is a YES!
As long as you store the cookies in an airtight container, you can store them for up to 2 weeks. 
If you choose you can also freeze the cookies.  If you choose to freeze them, don’t sprinkle them with powdered sugar until after you have defrosted them.
