Ingredients You’ll Need
It truly doesn’t get simpler than this: just a handful of essential ingredients, each playing a part to create cookie magic. Don’t skip or swap – every element here is chosen for a reason, ensuring those perfect zesty shortbread bites that everyone will be reaching for!
- Unsalted Butter (1 cup, softened): The heart of any shortbread – gives the cookies their tender, rich crumb and delicate flavor.
- Powdered Sugar (1/2 cup for dough, 1/4 cup for dusting): Dissolves smoothly into the dough for a subtle sweetness, and adds a final touch of melt-in-your-mouth magic when dusted on top.
- Granulated Sugar (2 tablespoons): Helps create that signature crumbly but light texture, and adds a little extra sweetness.
- Fresh Key Lime Juice (2 tablespoons): The star of the show; gives the cookies their unmistakable zesty punch.
- Key Lime Zest (2 teaspoons): Intensifies the lime flavor and adds gorgeous little flecks of color throughout each cookie.
- Vanilla Extract (1/2 teaspoon): Rounds out the citrus notes with comforting warmth.
- All-Purpose Flour (2 cups): The backbone of the cookie, bringing that classic shortbread body and structure.
- Salt (1/4 teaspoon): Just enough to enhance every bright, buttery note in these cookies.
How to Make Key Lime Shortbread Cookies for a Zesty Treat
Step 1: Prep Your Oven and Pans
Before you dive into the dough, start by preheating your oven to 350°F (175°C). Cover two cookie sheets with parchment paper – this stops sticking and keeps cleanup wonderfully easy. Now you’re set for shortbread perfection!
Step 2: Cream the Butters and Sugars
In a large mixing bowl, beat the softened butter with the powdered and granulated sugars. The goal is to whip it until it’s pale, creamy, and fluffy – about 2-3 minutes. This step is how you get that classic shortbread melt-in-your-mouth effect and the base for the zesty twist to come.
Step 3: Blend in the Key Lime and Vanilla
Add the fresh key lime juice, plenty of zest, and vanilla extract into your creamed butter mixture. Give it a good mix until everything is evenly distributed. You should smell that gorgeous citrus aroma already wafting up – it’s your promise of zing in every bite!
Step 4: Mix the Dry Ingredients
Sprinkle in the all-purpose flour and salt, gradually, on low speed or gently by hand. Mix just until it all comes together – don’t overwork the dough, or your cookies might be tough. Shortbread dough is magic: as soon as it’s cohesive, you’re done.
Step 5: Shape and Chill
Scoop the dough out and shape it into a log roughly 2 inches in diameter. Wrap it in plastic wrap and chill in the refrigerator for at least 1 hour. This not only develops flavor but also makes it easy to slice perfect, neat rounds for baking.
Step 6: Slice and Bake
When chilled, slice your dough into 1/4-inch thick coins and set them on the prepared baking sheets, spaced an inch apart. Pop them into the oven and bake for 12-14 minutes, just long enough for the edges to sport the lightest golden hue.
Step 7: Cool and Finish
Once baked, let the cookies rest on the sheet for five minutes. Then carefully transfer to a wire rack to cool completely. Finish with a gentle snowfall of powdered sugar on top for that irresistible, photogenic finish. There you have it: Key Lime Shortbread Cookies for a Zesty Treat, ready to impress!
How to Serve Key Lime Shortbread Cookies for a Zesty Treat

If you want to get playful, sandwich two cookies with a swipe of lime curd or creamy vanilla frosting for a truly spectacular treat.
Make Ahead and Storage
Storing Leftovers
To keep your Key Lime Shortbread Cookies for a Zesty Treat irresistibly fresh, store them in an airtight container at room temperature for up to one week. Be sure to layer them with parchment so the powdered sugar stays lovely and even.
Freezing
The dough for Key Lime Shortbread Cookies for a Zesty Treat freezes beautifully. Wrap the dough log tightly in plastic and then in foil, and stash in the freezer for up to two months. Slice and bake straight from frozen, just adding a minute or two to the baking time.
Reheating
If your cookies lose a bit of crispness, pop them in a preheated 300°F (150°C) oven for about 3-4 minutes. Let them cool on a rack, then dust again with powdered sugar. They’ll taste freshly made all over again!
FAQs
Can I use regular limes instead of key limes?
Absolutely! While key limes have a slightly more floral, tart edge, regular Persian limes do a fine job standing in. The cookies will still be delightfully zesty and refreshing, though you might notice a subtle difference if you’re a true key lime aficionado.
Do these cookies spread much as they bake?
Nope! Thanks to the chilled dough and the sturdy shortbread base, Key Lime Shortbread Cookies for a Zesty Treat hold their shape beautifully. The edges might crisp up a touch, but you’ll still end up with the perfect round cookies every time.
Can I make Key Lime Shortbread Cookies for a Zesty Treat gluten-free?
You can definitely substitute your favorite 1:1 gluten-free flour blend. The texture may be slightly different, but these cookies are pretty forgiving and will still pack plenty of that signature citrus punch.
Why do I need to chill the dough?
Chilling is the secret here! It prevents spreading and makes the dough easier to slice, helping you get those tidy, bakery-style rounds. Plus, this resting time lets all the zesty flavors meld perfectly.
How can I intensify the lime flavor?
Try rolling your still-warm cookies in a mix of powdered sugar and even more fresh lime zest. This gives a double burst of citrus at first bite and looks especially pretty. Or serve with a small bowl of lime curd for dipping!
