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.

How to Make Key Lime Cookies
- Prep: Preheat the oven to 375 degrees F. Line two baking sheets with parchment paper or silpats.
- Dry Ingredients: Combine the flour, baking soda and salt in a bowl.
- Wet Ingredients: In the bowl of stand mixer, cream the butter and sugars until light and fluffy. Then beat in the egg, key lime juice and vanilla until smooth.
- Combine: Slowly add the flour mixture to the wet ingredients and mix until just combined.
- Stir: Add the white chocolate and key lime zest to the dough and use a wooden spoon to stir them in.
- Scoop: Use a cookie scoop or spoon to drop spoonfuls of dough onto the prepared baking sheets.
- Bake: Bake the cookies for 8-9 minutes and be sure to not overbake them.
- Cool: Let the cookies cool on the cookie sheet for a few minutes and then move them to a wire cooling rack.
Keep scrolling through the post down to the recipe card to see all these instructions in full detail.

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.

Variations
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.

Lime lovers unite! I love lime in desserts! Whether it be lime cheesecake, key lime pie, or torta de limão, I am there for it! These white chocolate key lime cookies are the perfect combination of vibrant lime and creamy white chocolate! They taste incredible and the texture is muah! Yummmmmm!

Petunia
I wish recipes would stop claiming to be key lime when they’re just using regular limes. There’s a HUGE difference in flavor between key limes and regular limes.
Sweet Basil
Hi Petunia! You can definitely use key limes in this recipe. I actually prefer it with key limes. They are often hard to find here and quite a bit more expensive so I like to provide an alternative!
Annelie Zingmark
These cookies are sooo good! Everyone loved them! I wanted a little more lime taste so I had lime icing on top of them. Delicious!!
Oh Sweet Basil
Hi Annelie! That is perfect! I’m always for more citrus flavor! So glad you enjoyed them!
Peggy
Limes vary by a lot. How much lime juice do you use? The recipe does not specify.
Can’t wait to try this recipe..
Sweet Basil
Hey Peggy! It ends up being about 1 Tablespoon of lime juice. You’re going to love this one!!
Brad
I love this recipe, thanks alot. ,I use Ghirardelli whit bars and bake 9 min and 10 min , high alttitude ,also made it with lemon instead and was awesome ,like lemon cake
Sweet Basil
Thank you so much for the feedback Brad!
Megan
I made these today…they are very yummy! Really the flavor is great. But, they spread and were too cakey. Did not look like the picture at all. I did not add too much flour, or overmix; I experimented with oven temperature and refrigerating the dough and the texture was still off. Thank you for the recipe though, I like to try new things 😉
Sweet Basil
Oh darnit! We’ve made them a ton and they always turn out. What fat did you use, butter, margarine or shortening?
Megan
I used unsalted butter. Seems like when I stray from my tried-and-true recipes, I get cakey cookies. Happened with the cookie recipe on the back of the Imperial margarine box too when I needed sweets in a hurry. Luckily my kids are not picky like their mama 😉
Sweet Basil
shoot, I’m so sorry. I would just recommend creaming the butter and sugar longer, or use a little less lime juice as maybe I’m heavier handed with the flour. We actually love to skip lime in this recipe and use chocolate chips. It’s delicious!
Laura
can I ask you all something without appearing to be rude in any way ?
you all are saying .. you love or can’t buy “key limes” … that’s leaving me confused …
I always thought that “key lime” meant kiwi and lime … but I see the recipe doesn’t call for kiwi …
so, what exactly IS key lime ?
and someone mentioned the “bottled stuff” … bottled lime juice or something else ??
please someone let me know, these cookies look and sound amazing !!
thank you !!!
Sweet Basil
Hey Laura,
Key limes are like little baby limes in size. They taste a little bit different from a normal lime, but not enough to really tell a difference. Since they are mostly in Florida and that area they are hard to find out west, but in the juice isle, by lemon juice they often have bottled key lime juice so I use that or normal limes.

Sarah
I want to make these cookies and am wondering if you used actual key limes (as implied in the title), or regular limes (as implied in the ingredients list). Of course if you have ever worked with key limes, you know there is a big difference between the flavor and size of the two. Thanks!
Sweet Basil
Hi sarah, I have such a hard time getting Key Limes here in Utah. They are either sold out or not sold at all. I had to use limes a few times to perfect this recipe, after the first time using key limes. So annoying, but since the recipe turned out so yummy I just put the limes. That first batch was awesome with key limes though. I wish I could get my hands on freshies, but maybe next time I’ll see how the bottled stuff goes.
Rosemarie
I think that Sarah was trying to find out — as I am — about the quantity of lime juice and zest to use in the recipe. Key limes will obviously yield a lot less juice and zest than regular limes — and boy are they a pain to juice! I am fortunate that not only do I live in Florida, I have a key lime tree in my back yard! Since I’m making these cookies now and don’t have time to wait for a reply, I’m going to use 6 key limes instead of 2. Thanks for the recipe — I’ll let you know how they turn out!
Rosemarie
Update — the cookies turned out great! My boyfriend loved them. However, next time I think I’ll use a bit more key lime juice.
Sweet Basil
Thanks Rosemarie! I love when people take the time to come back with updates. We’ve found that the zest can help pull more flavor without changing the texture so maybe we will try it now with more zest!
Sweet Basil
Oh, you are so lucky! Key limes are so hard to find around here that anything using lime is called key lime just because we can’t get it. I’ll get experimenting though
scrambledhenfruit
I love anything lime flavored- these cookies look so good! With a tall glass of iced tea, they'd hit the spot. 🙂
