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.

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.

  • 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.

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.

    These are the bomb and I think it’s the first recipe I’ve tried from Pinterest that actually looked like the photo – YAY! 🙂 Seriously though, these are so delicious. They’re crispy but chewy and just simply divine. We had zero self control and devoured them. Thanks for the great recipe!

  2. Loved this recipe, just wish the lime flavor was a bit stronger. Used fresh lime juice. Would it be stronger with key west lime juice in the bottle?

  3. 5 stars
    Absolutely love these. It’s a special occasion cookie and I’m planning to share on Mother’s Day tomorrow with friends. This is the second time I have made them. Thank you so much for sharing.

  4. With the lime zest on top (in pictures) do you put that on as soon as they come out of the oven? It doesn’t mention within recipe.

    1. From the recipe: “Divide the dough using a 2 oz ice cream scoop, leaving 3-inches apart to allow for spreading. (A regular size ice cream scoop is 4 oz)”

  5. 5 stars
    Loved the cookies! Great texture and wonderful flavor. We added lime frosting to half. Either way a winner! Thank you for sharing it. This is a fan favorite!

  6. 5 stars
    These cookies were delicious! The only downfall for me was not much of a lime flavor. I used key lime juice- next time I may add more but very tasty nonetheless!!

  7. I want to make these cookies! I am not a big fan of coconut but do like the taste and texture much better toasted. Has that nutty flavor. Could toasted be used and if there is an issue during the chilling process could the toasted coconut be added just before baking?

    1. That’s a great question, I make these cookie just as written. I would think lightly toasted may work however keep in mind, it will cook further while the cookie is baking.

    1. I make this recipe just as written. If you try it, come back and comment with changes you made for gluten free.

  8. The title says Key Lime but the recipe calls for just lime juice. If I use real key lime, should I use the same amounts or is it more bitter?

    1. Use the same amount. The reason is, some people find it hard to locate key limes. please feel free to make these cookies with either.

      1. If you followed the recipe, they should be the same. If you’d like them flatter, flatten them out slightly on the pan prior to baking. When doing so they may take less time to bake so keep an eye on them.

      1. Hi there, hubby hates coconut can I just omit it or do I need to adjust other measurement ingredients in some way, would like to substitute walnuts or macadamia nuts.

      2. You can omit it but, it will change the texture. Adding nuts is fine, of course.
