This recipe’s charm lies in its simplicity, with each ingredient playing an essential role in creating the perfect Key Lime Cookie. From a tender buttery base to the fresh key lime juice that delivers that signature zing, every element is chosen to highlight fresh, clean flavors with a delightful texture.
- 1 cup all-purpose flour: The foundation of your cookie, providing structure and softness.
- 1/2 teaspoon baking soda: Helps the cookies rise just enough for a tender texture.
- 1/2 teaspoon baking powder: Adds a gentle lift and lightness to the dough.
- 1/4 teaspoon salt: Balances the sweetness and enhances all the flavors.
- 1/2 cup unsalted butter, softened: Gives richness and moisture, making the cookies irresistibly tender.
- 1/2 cup granulated sugar: Sweetness with a bit of bite for the perfect cookie crust.
- 1 large egg: Binds the dough and adds a slight chewiness.
- 1 teaspoon vanilla extract: Deepens the flavor, complementing the lime perfectly.
- 1 tablespoon key lime juice (freshly squeezed): The star ingredient for that fresh, tart zing.
- Zest of 2 key limes: Packs an aromatic punch and bright citrus notes.
- 1/4 cup powdered sugar (for dusting): Adds a delicate sweetness and pretty finishing touch.
How to Make Key Lime Cookies Recipe
Step 1: Preheat and Prepare Your Baking Surface
Start by heating your oven to 350°F (175°C), which is essential so it’s ready to go when your dough is mixed. Line a baking sheet with parchment paper or a silicone mat to prevent sticking and help the cookies bake evenly.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. This combination ensures your cookies achieve the ideal rise and texture without becoming dense or flat.
Step 3: Cream Butter and Sugar
In a large bowl, beat the softened butter with granulated sugar until the mixture becomes light, fluffy, and pale—about 2 to 3 minutes. This step incorporates air, creating a delicate crumb.
Step 4: Add Wet Ingredients
Beat in the egg, vanilla extract, freshly squeezed key lime juice, and lime zest. This combination brings moisture, flavor, and that signature key lime brightness right into your dough.
Step 5: Combine Dry and Wet Mixes
Gradually stir the dry ingredients into the wet mixture, mixing just until combined. Over-mixing can make cookies tough, so be gentle to keep them tender and soft.
Step 6: Scoop Dough onto Baking Sheet
Drop tablespoon-sized portions of dough onto your prepared baking sheet, spacing the cookies about 2 inches apart to allow for slight spreading during baking.
Step 7: Bake to Perfection
Bake your cookies for 8 to 10 minutes, watching for golden edges while keeping centers soft and slightly underbaked. This guarantees a chewy, melt-in-your-mouth texture that’s oh so satisfying.
Step 8: Cool and Dust with Powdered Sugar
Let the cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Once cool, dust with powdered sugar for a charming, lightly sweet finish that also enhances their citrus allure.
How to Serve Key Lime Cookies Recipe
Garnishes
Elevate the presentation with thin slices of fresh key lime or a small sprinkle of additional zest for an extra pop of color and aroma. A light drizzle of white chocolate can also add a delightful creamy contrast if you’re feeling adventurous.
Side Dishes
Pair these cookies with a scoop of vanilla ice cream or a dollop of whipped cream for a refreshing dessert course. They also complement a cup of herbal tea or a chilled glass of lemonade beautifully, making them perfect for brunch or afternoon treats.
Creative Ways to Present
Tray these cookies alongside other citrus-inspired sweets for an eye-catching dessert platter. You can also sandwich two cookies together with a tangy lime-infused cream cheese frosting for a delightful twist that’s perfect for parties.
Make Ahead and Storage
Storing Leftovers
Place cooled cookies in an airtight container at room temperature to keep them fresh and chewy for up to five days. Layer with parchment paper to prevent sticking and preserve their delicate texture.
Freezing
Key lime cookies freeze wonderfully! Arrange them in a single layer on a baking sheet to freeze individually before transferring to a freezer-safe container. They’ll keep for up to three months, ready to thaw and enjoy any time you crave that bright citrus burst.
Reheating
Warm these cookies gently in a low oven (about 300°F/150°C) for 3 to 5 minutes, or microwave for 10 to 15 seconds to bring back their fresh-baked softness. Just be careful not to overheat or they might dry out.
FAQs
Can I substitute regular lime for key lime in the recipe?
Absolutely! While key limes have a unique tartness and fragrance, regular limes can be used with great results, though the flavor might be slightly less intense.
What if I don’t have baking powder on hand?
If needed, you can make a substitute by mixing 1/4 teaspoon baking soda with 1/2 teaspoon cream of tartar for each 1/2 teaspoon baking powder required.
Can I make these cookies gluten-free?
Yes, by swapping all-purpose flour with a gluten-free flour blend designed for baking, you can enjoy these cookies without gluten—just check that the blend contains xanthan gum for proper texture.
Is it important to use unsalted butter?
Unsalted butter is preferred so you can control the salt level precisely; however, if you only have salted butter, reduce the added salt in the recipe accordingly.
How long will the cookies stay fresh?
When stored properly in an airtight container at room temperature, these cookies stay fresh for up to five days, long enough to share with friends or savor over a few afternoons.

Ingredients
Dry Ingredients
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
Wet Ingredients
- 1/2 cup unsalted butter, softened
- 1/2 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 tablespoon key lime juice (freshly squeezed)
- Zest of 2 key limes
For Dusting
- 1/4 cup powdered sugar
Instructions
- Preheat the oven: Set your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper or a silicone baking mat to prevent sticking.
- Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt to combine evenly.
- Cream butter and sugar: In a separate large bowl, beat the softened unsalted butter with granulated sugar until the mixture becomes light and fluffy, which should take about 2 to 3 minutes.
- Add wet ingredients: Incorporate the large egg, vanilla extract, freshly squeezed key lime juice, and lime zest into the butter and sugar mixture, beating until fully combined and smooth.
- Combine wet and dry: Gradually add the dry ingredients into the wet mixture, stirring gently until just combined to avoid overmixing which can make cookies tough.
- Portion the dough: Using a tablespoon scoop, drop dollops of dough onto the prepared baking sheet, spacing each about 2 inches apart to allow room for spreading.
- Bake the cookies: Place the baking sheet in the preheated oven and bake for 8 to 10 minutes, or until the cookie edges turn slightly golden while the centers remain soft to the touch.
- Cool the cookies: Let the baked cookies rest on the baking sheet for 5 minutes to firm up, then transfer them to a wire rack to cool completely.
- Dust with powdered sugar: Once cooled, lightly dust the tops of the cookies with powdered sugar for a sweet, decorative finish.
Notes
- Use fresh key lime juice and zest for the best citrus flavor; bottled juice will not deliver the same brightness.
- Do not overbake; cookies should be soft in the centers to maintain a tender texture.
- The dough can be chilled for 30 minutes before baking if you want thicker cookies.
- Store cooled cookies in an airtight container at room temperature for up to 5 days.
- For a twist, try mixing in white chocolate chips or macadamia nuts for extra texture.
