Key Lime Cookies
There’s something truly special about the bright, zesty flavor of key lime. It tastes like sunshine and warm weather, instantly transporting me to a tropical state of mind, no matter the season.
I’ve always been a huge fan of classic key lime pie, but I wanted that same sweet and tangy punch in a portable, shareable treat. This recipe for Key Lime Cookies is the perfect answer, marrying the soft, chewy texture of a perfect sugar cookie with that unmistakable citrus zing.
What You’ll Need
Here are the simple ingredients required to make these delightful cookies.
- Flour: All-purpose flour provides the structure for the cookies.
- Baking Soda: This helps the cookies rise and become soft.
- Salt: A little salt enhances all the other flavors.
- Unsalted Butter: Use room temperature butter for the best creamy texture.
- Sugars: A mix of granulated and light brown sugar gives the perfect balance of sweetness and chewiness.
- Egg: One large egg binds the dough together.
- Vanilla Extract: Adds a subtle warmth to the cookie base.
- Key Lime Zest & Juice: The stars of the show! Fresh is always best for the brightest flavor.
- White Chocolate Chips: These add a sweet creaminess that pairs beautifully with the tart lime.
- Powdered Sugar: For making the simple, tangy glaze.
Pro Tips
Over the years, I’ve learned a few things that take these cookies from good to absolutely perfect. Here are my best tips for success.
- Don’t Skip the Chill Time: This dough is quite sticky. Refrigerating the scooped dough for at least 30 minutes is crucial. It makes the dough much easier to roll into smooth balls and prevents the cookies from spreading too much in the oven.
- Use Fresh Key Limes: While bottled juice works in a pinch, the flavor from fresh key lime juice and zest is noticeably brighter and more aromatic. The zest, in particular, holds essential oils that infuse the entire cookie with flavor.
- Watch the Bake Time Closely: These cookies are best when they are soft and chewy, not crisp. Pull them from the oven the moment the edges are set, even if the centers look slightly underdone. They will finish baking on the hot pan. For my oven, 7 minutes is the magic number.
- Glaze Cool Cookies Only: Wait until the cookies are completely cool before adding the glaze. If you drizzle it on while they are still warm, the glaze will melt and soak in rather than setting up as a distinct, tangy layer on top.
Tools and Equipment
You don’t need any fancy equipment for this recipe, just some baking essentials.
| Tool | Purpose |
|---|---|

Substitutions and Variations
Want to change things up? Here are a few tested variations.
- Limes: If you can’t find key limes, regular Persian limes will work. The flavor will be slightly less tart and aromatic, but still delicious.
- Mix-ins: Feel free to omit the white chocolate chips for a simpler cookie. You could also substitute them with macadamia nuts for a crunchy, tropical twist.
- Glaze: For a thicker, frosting-like topping, use less lime juice to create a stiffer consistency.
Make-Ahead Tips
This recipe is great for preparing in advance. You can make the cookie dough, scoop it into balls, and store them in an airtight container in the refrigerator for up to 3 days.
You can also freeze the unbaked cookie dough balls for up to 3 months. When you’re ready to bake, just place the frozen dough on a baking sheet and add 1-2 minutes to the bake time. No need to thaw!
How to Make Key Lime Cookies
Follow these steps for soft, chewy, and tangy cookies every time.
Step 1: Line a light-colored baking sheet with parchment paper. In a small bowl, whisk together the flour, baking soda, and salt.
Step 2: In a separate, larger bowl, use an electric mixer to beat the room temperature butter with the granulated and brown sugars until smooth and creamy.
Step 3: Add the egg, vanilla extract, key lime juice, and key lime zest to the creamed butter mixture. Mix until just combined.
Step 4: Slowly add the dry ingredients to the wet ingredients, mixing on low speed until the dough comes together. Be careful not to overmix. Fold in the white chocolate chips.
Step 5: Use a cookie scoop to drop dough balls onto the prepared baking sheet. Cover and refrigerate for at least 30 minutes.
Step 6: Preheat your oven to 375°F. Once the dough is chilled, roll the scoops into smooth balls and place them back on the baking sheet, about 2 inches apart.
Step 7: Bake for 7-8 minutes. The cookies should look set on the edges but still soft in the middle. Do not overbake. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Step 8: Once the cookies are cool, prepare the glaze. Whisk together the powdered sugar and 1 tablespoon of lime juice. Add more juice, a tiny bit at a time, until you reach a drizzling consistency. Drizzle the glaze over the cookies and sprinkle with extra zest if desired. Allow the glaze to set before storing.

- Pairing Suggestions: These cookies are wonderful with a cup of hot green tea or a tall glass of iced tea in the summer.
- Efficiency Tip: While the cookie dough is chilling, you can wash the mixing bowls and prepare your glaze ingredients. This streamlines the process and makes cleanup easier.
Leftovers and Storage
Store the cookies in a single layer in an airtight container at room temperature. Because of the glaze, it’s best not to stack them. They will stay fresh for up to 5 days.
These cookies also freeze beautifully. Once the glaze is completely set, place them in a freezer-safe container or bag, with parchment paper between the layers. They will keep for up to 3 months. To thaw, leave them at room temperature for an hour.
Frequently Asked Questions
Q1. My cookies spread too much. What went wrong?
Ans: This is usually because the butter was too soft or the dough wasn’t chilled long enough. Ensure your butter is at room temperature (cool to the touch but dents slightly when pressed) and don’t skip the 30-minute refrigeration step.
Q2. Can I make these without an electric mixer?
Ans: Yes, you can. It will take more arm strength, but you can cream the butter and sugar with a wooden spoon or a sturdy whisk. Just make sure the mixture is very smooth and creamy before adding other ingredients.
Q3. My cookies don’t taste very limey. How can I get more flavor?
Ans: For the most intense lime flavor, be sure to use fresh key lime zest and juice. The zest contains the most potent flavor. You can even add a little extra zest to the dough. The glaze on top is also essential for that final pop of tartness.
