Key Limes Versus Persian Limes
What’s the difference between a key lime and a Persian lime most common in the produce department at the grocery store?
- Key limes are smaller and lighter in color than regular limes. The skin is noticeably thinner.
- A bright green key lime will be more tart than a slightly yellow key lime. The yellow hue signifies a more ripe lime as opposed to a “green” key lime. Either will work.
- Key limes tend to have a flavor that’s tart, but not overly acidic compared to lemons, with aromatic floral notes.
Easy Key Lime Coconut White Chocolate Chip Cookies Recipe
I love making cookie dough in advance and baking fresh cookies when we’re ready for them. I’m a kid at heart when it comes to cookies, I find them simply irresistible. To me, warm cookies are one of those small indulgences that make life so sweet. Literally.
Key ingredients you’ll need to make Key Lime Coconut Cookies: (Scroll down for the full printable recipe card.)
- Flour – All purpose flour forms the base of the cookie dough.
- Leavening – Baking soda and salt give lift to the batter.
- Sugar – Granulated sugar for sweetness.
- Butter – Salted or unsalted butter for a rich flavor.
- Whole Eggs – Large eggs bind the cookie dough.
- Key Lime – Both fresh key lime juice or lime extract and key lime zest, give the cookies their signature flavor.
- Chocolate – White chocolate baking chips and sweetened flaked coconut expand the flavor profile.
- Flavoring – Vanilla extract balances the flavor.

How to Make the Best Key Lime Coconut White Chocolate Chip Cookies Recipe
- Heat Oven and Prepare Pans – Preheat oven and lined baking sheet with parchment paper.
- Sift the Dry Ingredients – Sift together the flour, baking soda and salt in a large bowl.
- Wet Ingredients – Cream together the butter and sugar with the vanilla extract, key lime juice (or extract) and zest until light and fluffy. Add the eggs.
- Combine with the Flour Mixture – Lower the speed of the mixer and gradually add the sifted dry ingredients mixing until full moistened.

Kitchen Equipment to Make Key Lime Coconut Cookies
- A stand mixer or a hand mixer.

- Balloon whisk.
- Cookie sheets or baking sheets lined with parchment paper or a silicone mat.

Recipe Variations, Tips and Substitutions
- Key Lime Flavor Alternatives – When deciding which to use, lime juice or lime extract keep in mind that extract has a more concentrated lime flavor. The amount of fresh key lime zest can be increased for a more intense lime flavor, too. Lime extract is available with the other flavorings and extracts on the baking aisle of most grocery stores. Using it will give the cookies a more intense lime flavor.
- Soften the Butter to Make it Easier to Cream – It’s important when making these cookies to allow time for the butter to soften so that it will incorporate evenly with the granulated sugar and eggs.
- Nuts – You can add 1/2-1 cup of macadamia nuts, pecans or walnuts to the cookie dough for crunch.
- Coconut – Shredded coconut gives these cookies a delightfully chewy texture. You could omit it or use coconut extract instead, for a pop of coconut flavor. The texture will change, but the cookies will still be delicious.
- Icing – I don’t typically frost these delicious cookies but you could, if you want. A creamy lime frosting made with powdered sugar and lime juice would be tasty!
Storage and Leftovers
- Cookie Dough Storage – This key lime coconut cookie dough keeps well when chilled in an airtight container in the refrigerator, when starting with the freshest of dairy products. You can store it up to one week in the fridge.
- Make-Ahead Tip – When making the cookie dough ahead of time make sure that the cookie dough is kept tightly covered to keep moisture and air from changing the texture of the dough.
- Thawing – When thawing frozen a tub of cookie dough, it’s advisable to thaw it in the refrigerator so it’s easier to scoop cookies. You may also choose to freeze mounds of dough and in that instance, you can bake the cookies from frozen.
- Storing Baked Cookies – Store baked White Chocolate Chip Key Lime Cookies in an airtight container at room temperature for up to 4 days.

Would you be able to make them into bars rather than cookies do you think? They sound amazing!
Most cookie dough recipes can be adapted to bars, yes. Just adjust the baking time to accommodate bars will take longer to bake.
Look forward to trying these. I have shredded unsweetened coconut on hand. What do you think? Could I use it?
I haven’t tested this recipe using unsweetened coconut. If you try it, let us know how it goes!
It went great. With the white chocolate it was sweet enough
Love it! Made it with gluten free flour, coconut sugar and sugar free white chocolate chips! Healthier & delicious!
Could you use lime extract and key lime juice?
You can use lime extract but I don’t recommend adding extra liquid.
I actually used both & it was great! At first the lime extract tasted too strong in batter, but once cooked they were great!
We tried these and they turned out great! There is a subtle lime flavor if you only use lime juice (I used fresh key lime juice), but I think more juice would make the bottoms of the cookies burn, as the places with white chocolate chips sort of crisped. But these are super fluffy, and even only using 7 oz coconut instead of the called for 10 oz (shrinkflation) was still a TON of coconut, like a fluffy macaroon. Delish! Thank you for this recipe!
I just made these today. Followed the recipe exactly..using key lime extract, but then regular lime zest.
the flavor is amazing. The cookies are flat…and greasy….eek! What did I do wrong..or what can I adjust next time? thanks!
The quality of white chocolate chips across brands aren’t all created equal. They could potentially do that to a cookie, I prefer Ghirardelli myself. Also, did you measure the flour correctly and use a good quality butter? Otherwise, I’ve made these cookie many times and never experienced that, just some possibilities to mention.
Thanks for the feedback. I’ll take all into consideration…it’s a great recipe, and already got rave reviews from friends. Just need to tweak a couple things! thank you.
Maybe butter was too soft?
Mine actually burned at 12 minutes with my gas stov. 10 minutes was better but mine turned out flat as well. Yummy though.
Gas bakes different from electric for sure, glad you enjoyed them!
I add some cornstarch to all of my cookie recipes if it doesn’t already call for it.
We added macadamia nuts.
What to use if you can’t find key limes to make the zest. I have bottled key lime juice but can’t find the actual lime to zest.
You can use Persian limes from the produce department, no problem.
I use regular lime juice and zest. They are more coconut than lime. (very yummy) Would they have a stronger lime taste with keylime? Extract? I’d prefer that. TY
This recipe calls for lime extract for a pop of lime flavor in addition to the zest. If you omitted it, you should try it with the extract for a more concentrated flavor.
Perhaps a tiny bit of lime oil.
Made these for Easter weekend and they were a hit! Made lots of cookies to share with neighbors too. I used the extract and zest of one lime and they were amazing! The dough is very thick but created delicious, beautiful cookies! I made a batch, refrigerated the dough and made more cookies the next day.
Interesting that they are called Keylime cookies but there are no keylimes (or keylime juice) called for in the recipe.
There is both key lime juice and key lime zest called for in this recipe.
I love these cookies, as do my coworkers. The only change I make is using half tsp. almond extract and half tsp. of vanilla. I think the almond helps bring out that limey flavor just a bit more. But overall I’m so glad I found this recipe. They don’t feel as heavy as say a chocolate chip-esq cookie would. Especially in these summer months. 10/10 I share this recipe with anyone who asks. Thank you for all you do!
