The first time I pulled a tray of these key lime cookies out of the oven, the whole kitchen was filled with this zesty, sweet aroma I honestly wish I could bottle up. You know that feeling when you’re craving something bright and citrusy, but you want it to be simple, too? That’s exactly how these key lime cookies with lime glaze came to life. I’d been dreaming up a recipe that would capture all the sunshine of a key lime pie—minus the fuss of making a crust or finding a pie plate. These little cookies are soft, buttery, and bursting with tang. Every bite is like a mini-vacation to the Florida Keys (even if you’re just sitting at your kitchen counter in fuzzy socks).
My love affair with key lime goes back to a family trip where we tried every pie from Miami to Key West. But let’s face it—sometimes you just want a handheld treat you can grab on the go. That’s why I started tinkering with this key lime cookies recipe. After a few rounds (okay, maybe more than a few—my neighbors definitely didn’t mind), I found the perfect balance of tart and sweet. The real kicker? That shiny lime glaze on top. It hardens just enough for a satisfying crack, but it’s soft enough to melt on your tongue. And if you’re a Pinterest lover like me, you’ll appreciate how pretty these look on a dessert platter—those little flecks of zest are like edible confetti!
These key lime cookies are my go-to for spring parties, backyard BBQs, or just a Tuesday when I need a pick-me-up. They’re easy enough for beginner bakers and quick enough that you won’t spend your whole day in the kitchen. I’ve tested this recipe more times than I can count, and I can say with total confidence: these are the best tangy dessert cookies you’ll make this year. Whether you’re baking for family, friends, or just yourself (no judgment here), I think you’ll fall hard for this easy key lime cookies recipe with lime glaze.

What really sets this key lime cookies recipe apart? It’s all about the texture and flavor punch. I blend the zest right into the dough for a fragrant burst in every bite, and the glaze isn’t just a drizzle—it’s a full-on lime blanket (because more citrus is always better, right?). I even tested these with regular limes versus key limes, and while both work, there’s something special about the floral, tart notes of true key limes. This is the recipe where you want to go the extra mile if you can.
Honestly, these cookies are the kind that make you pause after the first bite. They’re comforting—familiar but with a twist—and they have that “bet you can’t eat just one” effect.

(Don’t say I didn’t warn you!)
Ingredients Needed for Easy Key Lime Cookies with Lime Glaze
This key lime cookies recipe keeps things nice and simple—no oddball ingredients or expensive specialty items. Here’s what you’ll need for both the cookie dough and the tangy lime glaze:
For the Cookie Dough
- All-purpose flour (2 cups / 240g) – Gives structure and that perfect, tender crumb.
- Cornstarch (2 tablespoons / 16g) – Makes the cookies extra soft and melt-in-your-mouth.
- Baking powder (1 teaspoon / 4g) – A little lift so they don’t end up flat.
- Salt (½ teaspoon / 3g) – Balances the sweetness and brightens the lime flavor.
- Unsalted butter (½ cup / 113g, room temperature) – For rich, buttery flavor; I use Kerrygold when I want to splurge.
- Granulated sugar (1 cup / 200g) – Sweetens and helps the cookies brown nicely.
- Egg (1 large, room temperature) – Helps bind everything together.
- Key lime zest (1 tablespoon / about 2 key limes) – Adds intense lime aroma and flavor; regular limes work if needed.
- Key lime juice (3 tablespoons / 45ml, freshly squeezed) – Gives the cookies their signature tang. Bottled key lime juice can be used, but fresh is best.
- Vanilla extract (1 teaspoon / 5ml) – Just a touch for warmth.
For the Lime Glaze
- Powdered sugar (1 cup / 120g, sifted) – Makes a silky-smooth glaze.
- Key lime juice (2-2.5 tablespoons / 30-37ml) – For that extra hit of citrus on top.
- Key lime zest (1 teaspoon, optional) – Sprinkle on top for a pop of color and flavor boost.
Ingredient Notes & Substitutions
- If you can’t find key limes, regular Persian limes will do. The flavor is slightly less floral, but still plenty tangy.
- For gluten-free cookies, swap the all-purpose flour with your favorite 1:1 gluten-free baking mix (I like King Arthur’s).
- Want to make it dairy-free? Use vegan butter (like Earth Balance) and double-check your powdered sugar is vegan.
- If you love coconut, try swapping ¼ cup of flour for unsweetened shredded coconut for a tropical twist.
- No fresh limes? Bottled key lime juice works in a pinch, but zest is a must for real flavor.
Most of these are pantry staples—honestly, the only thing I ever need to grab is the limes. If you’re a true citrus fan, keep a bag of key limes in your fridge—they last a good while and make everything taste brighter.
Equipment Needed for Easy Key Lime Cookies
- Mixing bowls: At least two—one for dry ingredients, one for wet. Glass or stainless steel works best (I find plastic sometimes holds on to citrus oils).
- Electric mixer: Handheld or stand mixer makes creaming butter and sugar much easier. I’ve made these by hand in a pinch, but your arm might get tired!
- Microplane or fine grater: For zesting the key limes—seriously, a good zester is worth every penny. If you only have a box grater, use the smallest holes.
- Measuring cups and spoons: Accurate measuring helps with cookie consistency. Digital kitchen scales are even better if you’ve got one.
- Baking sheet: Lined with parchment paper or a silicone mat for easy cleanup and even baking.
- Cookie scoop (optional): For uniform cookies, but you can use a tablespoon and your hands if needed.
- Wire rack: For cooling and glazing—otherwise, the glaze can get a bit soggy underneath.
If you don’t have a mixer, a sturdy wooden spoon and some elbow grease will work. I’ve even used a fork to cream butter in a small batch! For the baking sheet, plain aluminum is fine, but if you have a light-colored one, it helps prevent over-browning on the bottom.
Maintenance tip: If you use a microplane for zesting, rinse it right away—dried zest is stubborn. And if you’re buying new tools, don’t break the bank; budget-friendly sets do the trick just fine for this recipe.
How to Make Easy Key Lime Cookies with Lime Glaze
-
Prep Your Ingredients (5 minutes):
- Bring butter and egg to room temperature for easier mixing and fluffier cookies.
- Wash and zest the key limes first, then juice them. (Trust me, zesting after juicing is nearly impossible.)
-
Mix Dry Ingredients (2 minutes):
- In a medium bowl, whisk together 2 cups (240g) all-purpose flour, 2 tablespoons (16g) cornstarch, 1 teaspoon (4g) baking powder, and ½ teaspoon (3g) salt.
- Set aside. This blend keeps cookies tender and helps them hold their shape.
-
Cream Butter and Sugar (3 minutes):
- In a large mixing bowl, beat ½ cup (113g) unsalted butter with 1 cup (200g) granulated sugar on medium speed for 2-3 minutes, until light and fluffy.
- The mixture should look pale and airy—proper creaming is key for a soft texture.
-
Add Egg, Zest, and Flavorings (2 minutes):
- Beat in 1 large egg, 1 tablespoon key lime zest, 3 tablespoons (45ml) key lime juice, and 1 teaspoon vanilla extract until well combined.
- Don’t worry if it looks a little curdled—the flour will bring it all together.
-
Combine Wet and Dry Ingredients (2 minutes):
- Gradually add the dry ingredient mix to the wet ingredients, beating on low speed or stirring by hand.
- Stop as soon as the flour disappears—overmixing leads to tougher cookies.
- The dough should be soft and slightly tacky, but not sticky.
-
Chill the Dough (20 minutes):
- Cover the bowl with plastic wrap and refrigerate for at least 20 minutes.
- This helps prevent spreading and gives you thicker, chewier cookies.
- If you’re in a rush, 10 minutes in the freezer works in a pinch.
-
Preheat Oven and Shape Cookies (5 minutes):
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Scoop out dough by rounded tablespoons (about 1 ounce/28g each) and roll into balls.
- Place 2 inches apart on the baking sheet.
-
Bake (10-12 minutes):
- Bake for 10-12 minutes, until edges are just barely golden and centers look set but still soft.
- Don’t overbake! The cookies will firm up as they cool.
- If some cookies spread unevenly, gently nudge them back into shape with a spoon right out of the oven.
-
Cool (10 minutes):
- Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before glazing.
- Warm cookies may melt the glaze too much, so patience pays off here.
-
Make the Lime Glaze (2 minutes):
- In a small bowl, whisk together 1 cup (120g) powdered sugar and 2–2.5 tablespoons (30–37ml) key lime juice until smooth and pourable.
- If too thick, add a few drops of juice at a time; if too thin, add more sugar.
-
Glaze and Garnish (5 minutes):
- Spoon or drizzle glaze over cooled cookies.
- Top with extra lime zest while glaze is wet for a pretty finish and extra zing.
-
Let Set and Enjoy!
- Allow glaze to set for about 15 minutes before stacking or serving (if you can wait that long).
- Store in an airtight container at room temperature.
Tip: If you’re baking on a hot day, chill your shaped dough balls for 5 extra minutes before baking to keep the cookies thick and chewy.
Cooking Tips & Techniques for the Best Key Lime Cookies
- Use fresh key lime zest and juice: The flavor is way more intense than bottled juice alone. A microplane makes zesting a breeze.
- Chill the dough: I used to skip this step, but trust me—it’s what keeps your cookies thick and prevents them from spreading into pancakes. The difference is night and day.
- Don’t overwork the dough: Mix just until the flour is gone. Overmixing = tough cookies. (I learned this the hard way after my first batch came out dense and dry!)
- Watch the bake time: Pull the cookies as soon as the edges are barely golden. They’ll look a little underdone in the center, but they’ll set up as they cool. Overbaked cookies lose their soft, chewy magic.
- Glaze on a wire rack: Place parchment or wax paper under the rack to catch drips and make cleanup a snap. Glazing while cookies are fully cooled is key to that lovely sheen.
- Troubleshooting spreading: If your cookies spread too much, your butter may have been too soft or the dough too warm. Chill longer next time, or try baking a test cookie first.
- For stronger lime flavor: Add a few drops of pure lime extract to the dough or glaze. Don’t go overboard—a little goes a long way!
- Batch baking: If you’re doubling or tripling the recipe, only bake one tray at a time for even results, or rotate trays halfway through the bake time.
Honestly, my first time making these, I impatiently skipped chilling and ended up with flat, crispy cookies. Now, I always chill—even if it means an extra 15 minutes. It’s worth it for that soft, pillowy texture!
Variations & Adaptations for Key Lime Cookies
- Gluten-Free: Substitute a 1:1 gluten-free baking flour blend (like Bob’s Red Mill or King Arthur) for the all-purpose flour. I’ve tested this, and the cookies stay just as soft and flavorful.
- Dairy-Free: Use vegan butter and check that your sugar and powdered sugar are dairy-free. The flavor stays bright and the texture is nearly identical (I’ve even made these for a dairy-allergic kiddo in our neighborhood).
- Coconut Lime: Swap ¼ cup (30g) of flour for unsweetened shredded coconut. The coconut adds chewy texture and a tropical flavor that pairs perfectly with the lime.
- Meyer Lemon or Orange: Out of limes? Try Meyer lemon or even orange zest and juice for a different citrus twist. The cookies will be sweeter and less tart, but still absolutely delicious.
- Key Lime Sandwich Cookies: Double the glaze recipe and use it as a filling between two cookies for a decadent treat.
- Nutty Crunch: Add ½ cup (60g) finely chopped macadamia nuts to the dough for a bit of crunch and a nod to tropical desserts.
- Allergen-Friendly: For egg-free cookies, use a flax egg (1 tablespoon ground flaxseed mixed with 2½ tablespoons water, let sit 5 minutes). The cookies hold together well!
My personal favorite? The coconut-lime version. I tried it on a whim when I had leftover coconut in the pantry, and it’s become a new family favorite—especially with a sprinkle of toasted coconut on top.
Serving & Storage Suggestions
These key lime cookies are best served at room temperature, when the glaze has set and the cookies are perfectly soft. Arrange them on a platter with extra lime zest sprinkled over for a pop of color—they’re as pretty as anything you’d see on Pinterest! For a more elegant presentation, stack in a tiered dessert stand or nestle in cupcake liners for a party tray.
Pair with iced tea, lemonade, or a light sparkling wine for a refreshing treat. They also make a great addition to brunch buffets, dessert bars, or as a sweet surprise in lunchboxes.
- Storage: Keep cookies in an airtight container at room temperature for up to 4 days. The glaze stays shiny and the cookies remain soft.
- Freezer: Freeze unglazed cookies for up to 2 months. Thaw at room temp, then glaze fresh before serving.
- Reheating: No need to reheat, but if you want a just-baked feel, pop a cookie in the microwave for 6-8 seconds (glaze might get a bit sticky, but still tasty!).
- Flavor note: The lime flavor gets even brighter on day two as the glaze soaks in. Honestly, they may taste even better the next day—if they last that long!
Nutritional Information & Benefits
Each key lime cookie (with glaze) comes in around 110 calories, 4g fat, 17g carbs, and 1g protein. They’re lower in sugar than most bakery cookies, and you can cut the glaze if you want to trim it down further. The real highlight is the vitamin C from the key lime juice and zest—little boosts of antioxidants in every bite.
This recipe is nut-free as written and can be adapted to be gluten-free or dairy-free. Be cautious if you have egg allergies (see flax egg substitution above). I love that these cookies feel indulgent but are lighter and brighter than heavy, buttery treats. For me, they’re a sweet way to enjoy a little sunshine—no guilt attached.
Conclusion
If you’re searching for the ultimate tangy dessert, these easy key lime cookies with lime glaze are exactly what you need. They’re a little sweet, a little tart, and totally irresistible. The kind of cookie that disappears from the plate way too fast! I adore this recipe because it reminds me of family vacations, sunny days, and the simple joy of baking something beautiful and bright.
Feel free to put your own spin on them—add coconut, swap in different citrus, or double up the glaze if you’re feeling extra zesty. I’d love to hear how yours turn out! Leave a comment, share with your friends, or tag me in your Pinterest recreations. Happy baking, and may every bite bring you a bit of Florida sunshine!
Frequently Asked Questions About Easy Key Lime Cookies
Can I use regular limes instead of key limes in this cookie recipe?
Yes! Regular limes work just fine if you can’t find key limes. The cookies will be slightly less tart and floral, but still delicious and tangy.
How do I get the most juice out of small key limes?
Roll the limes firmly on the counter before cutting and juicing. You can also microwave them for 10 seconds to loosen up the juice inside. It’s a tiny extra step, but it makes a big difference!
Can I freeze the dough instead of baking all at once?
Absolutely. Scoop dough balls onto a tray, freeze until solid, then transfer to a freezer bag. Bake straight from frozen—just add 1-2 extra minutes to the baking time.
Why did my cookies spread too much in the oven?
If your dough was too warm, the cookies will spread more. Always chill the dough before baking, and make sure your butter isn’t melted or too soft.
How long will these cookies stay fresh?
Stored in an airtight container at room temp, they stay soft and tasty for up to 4 days. For longer storage, freeze unglazed cookies and add the glaze after thawing for best results.
