How to Make Key Lime Shortbread Cookies
1. Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper. This prepares your space for those delicious cookies, ensuring they bake evenly and don’t stick.
2. Cream together 1 cup of softened unsalted butter and 1/2 cup of powdered sugar in a mixing bowl until the mixture is light and fluffy. This step adds air to your dough, making your cookies tender!
3. Add in 2 cups of all-purpose flour and 1/4 teaspoon of salt gradually, mixing until just combined. Be careful not to overmix; you want a crumbly yet cohesive dough that comes together beautifully.
4. Stir in 1 tablespoon of key lime zest and 2 tablespoons of key lime juice until evenly distributed throughout the dough. The zest and juice will infuse a refreshing tang into your cookies, making them truly special.
5. Chill the dough in the refrigerator for about 30 minutes. Chilling helps to firm up the butter, resulting in perfectly shaped cookies that hold their form while baking.
Shape and Bake:
6. Roll out the chilled dough on a floured surface to about 1/4 inch thickness. This thickness allows for an ideal bake—crispy edges with a soft center that melts in your mouth.
7. Use a cookie cutter to cut out desired shapes and place them on the prepared baking sheet. Creative shapes can add a festive touch, perfect for any occasion!
8. Bake in the preheated oven for 15-20 minutes or until the edges are lightly golden. Keep an eye on them; you want that beautiful golden hue without overbaking!
9. Cool the cookies on the baking sheet for a few minutes before transferring them to a wire rack. This helps them set properly without breaking apart.
Glaze (Optional):
10. Mix 1 cup of powdered sugar with 1 tablespoon of key lime juice in a small bowl until smooth. This glaze adds an extra layer of sweet-tart flavor that complements your cookies perfectly.
11. Drizzle the glaze over the cooled cookies if desired, creating lovely patterns that make each cookie visually irresistible!
Optional: For extra zing, sprinkle some additional key lime zest on top after glazing.

Tips for the Best Key Lime Shortbread Cookies
- Butter Consistency: Use softened, but not melted, butter to ensure a light and fluffy texture in your cookies.
- Sifting Flour: Lightly sift your all-purpose flour before measuring to avoid compacting it, which can lead to denser cookies.
- Chill the Dough: Don’t skip chilling the dough for 30 minutes; this helps the cookies retain their shape while baking.
- Baking Time: Keep a close eye on the cookies as they bake; overbaking can result in dry shortbread instead of tender, buttery bites.
- Zest Freshly: Fresh key lime zest enhances flavor dramatically; avoid using dried zest for the best taste in your Key Lime Shortbread Cookies.
- Glaze Timing: Drizzle the optional glaze only after the cookies are fully cooled to prevent it from melting away.
How to Store and Freeze Key Lime Shortbread Cookies
Room Temperature: Keep your Key Lime Shortbread Cookies in an airtight container for up to 3 days to maintain their delightful texture and flavor.

Freezer: Freeze your Key Lime Shortbread Cookies for up to 3 months. Layer them between parchment paper in an airtight container to prevent sticking.

Key Lime Shortbread Cookies Recipe FAQs
What kind of butter should I use for the cookies?
For the best texture and flavor, use unsalted butter that has been softened to room temperature. This allows for easy creaming with powdered sugar, resulting in a light and fluffy cookie base.
How should I store the Key Lime Shortbread Cookies?
Once your cookies have cooled completely, store them in an airtight container at room temperature. They’ll stay fresh for up to a week. If you want to keep them longer, consider refrigerating them for up to two weeks.
Can I freeze the cookie dough for later use?
Absolutely! You can freeze the prepared cookie dough after chilling it. Wrap it tightly in plastic wrap and place it in an airtight container or freezer bag. It will keep well for up to three months. When you’re ready to bake, just thaw it in the fridge overnight before rolling out and cutting shapes.
What if my dough is too sticky or too dry?
If your dough feels too sticky, you can sprinkle a little more flour while rolling it out until it’s manageable. Conversely, if it’s too dry and crumbly, try adding a teaspoon of key lime juice or a tiny bit of softened butter until you achieve the right consistency.
How many cookies does this recipe yield?
This recipe yields about 4 servings of Key Lime Shortbread Cookies. Depending on the size of your cookie cutter, you can expect around 16-20 cookies, making them perfect for sharing with family and friends!
Can I substitute any ingredients for dietary considerations?
Certainly! For a dairy-free option, you can use vegan butter instead of unsalted butter. Additionally, if you’re looking to reduce sugar intake, consider using a sugar substitute that measures like powdered sugar for the glaze. Just keep in mind that this may slightly alter the flavor and texture!
