White Chocolate Key Lime Cookies

Satisfy your sweet tooth with these delicious White Chocolate Key Lime Cookies. Made with a zesty lime flavor and creamy white chocolate chips, these cookies are the perfect treat for any occasion.

A while back the hubby and I were trying to decide on dessert for the evening. We kept going back and forth about what we wanted. Then our dear friends stopped by and voted for trying out a new cookie, Key Lime Cookie. I actually really liked them. I would have liked a touch more lime in mine, but everyone else liked them as they were so I guess go with the majority vote.

Now I’ve circled back to this cookie recipe and updated it. You know I added more lime this time around, but feel free to dial it back if you want a more subtle lime flavor. This is the best key lime cookies recipe!

What Do I Need to Make Key Lime Cookies?

There are no surprises here! Just your typical cookie making ingredients plus come fresh lime juice and zest and white chocolate. That’s all you need! Here is your ingredients list…

  • Flour: just regular all purpose flour
  • Baking Soda: acts as a leavening agent to give the cookies their rise
  • Salt: enhances all the flavors
  • Butter: unsalted butter is preferred and you want it softened
  • Sugar: adds sweetness
  • Brown Sugar: adds additional sweetness and deeper rich flavor
  • Egg: gives the cookies structure and binds all the ingredients together
  • Vanilla Extract: adds flavor
  • Limes: you definitely need fresh limes for the zest and juice, either regular limes or key limes work great
  • White Chocolate Chips: or white chocolate chunks work great too

The measurements for all the ingredients can be found in the recipe card at the end of the post.

Can You Use Regular Limes Instead of Key Limes?

Key limes are smaller and are more sour and a little bitter compared to regular limes. They are commonly used in baking because of their bold flavor, but you can use regular limes in place of key limes for this recipe.

Tips for the Best Cookies

  • Don’t overmix the cookie dough after combining the wet and dry ingredients. Stop mixing as soon as everything is combined. Overmixing will result in tougher cookies.
  • Don’t press down the dough before baking. These cookies will be thick and chewy.
  • Don’t overbake the cookies. They are perfect when they are just starting to get golden around the edges. Let them cool for a few minutes on the baking sheet to finish baking.

I’m obsessed with the combination of white chocolate and citrus flavors. There’s just something magical about the brightness of the citrus with the comforting creaminess of vanilla white chocolate chips. So of course I’ve had to try similar flavor combinations with lemon and orange flavor! Try our orange creamsicle cookies and our glazed lemon cookies!

If you want to go on a flavor adventure with this key lime cookie recipe, add 1/2 teaspoon of coconut extract to this recipe and 1/2 cup of coconut flakes. That’s a special shout out to all my coconut lovers out there!

How Long Will Key Lime Cookies Keep?

Properly stored, freshly baked cookies will last for about 2 to 3 weeks at normal room temperature.

Crisp cookies should be kept in a container with a loosely fitting lid.

Soft cookies should be stored in an airtight container.

How Long Can You Freeze Key Lime Cookies?

Stored correctly, most cookies will keep for 3 months in the freezer.

Cooled cookies should be placed on a baking sheet in the freezer for 1-2 hours.

Once cookies are frozen, transfer to heavy duty freezer bags.
