Prepare all the ingredients.
In a mixing bowl, mix the butter, sugar, and lime zest until a paste forms.
Add the lime juice and salt.
Add the flour and gently mix until you have a uniform dough.
Shape the dough into a log and wrap it in plastic wrap. While it is still wrapped, gently roll it on the work surface to even out its thickness, and trim the ends. Refrigerate for about 20 minutes, or until firm enough to slice.
Remove the plastic wrap and cut it into rounds about 5 to 7 mm thick.
Arrange the cookies on a baking sheet lined with parchment paper, leaving a little space between each one.
Bake in an oven preheated to 350 °F/180 °C for about 10 to 15 minutes, or until the edges begin to brown slightly. Remove them from the oven and let the cookies cool completely.
Icing: Mix the powdered sugar with the lime juice. If necessary, gradually add a little more juice until you have a thick icing that’s easy to spread.
Using a spoon, place a small amount of icing on each cooled cookie and spread it out.
Finish by adding the lime zest.
Serve once the icing has set. Enjoy!

FAQ ❓

How should I store lime shortbread cookies with icing?

To keep lime shortbread cookies with icing crisp and flavorful, wait until the icing has dried completely before storing them. Then place the cookies in an airtight container, preferably in layers separated by parchment paper. At room temperature, they usually retain a good texture for about 5 to 7 days, as long as they are kept away from heat, moisture, and direct sunlight. Avoid storing them in the refrigerator, as the moisture can soften the cookies and affect the icing. If the weather is very hot, choose the coolest, driest spot in the kitchen. An important tip: never store the cookies while they are still warm, as steam trapped in the container will spoil their buttery texture.

How can I make the icing on lime cookies dry faster?

The icing will dry best if it is made to a firm consistency and applied in a thin layer. After icing the cookies, leave them on a wire rack or a surface lined with parchment paper in a dry, well-ventilated place. Depending on its thickness, the icing may start to set in about 30 minutes, but it’s best to wait a few hours before stacking or storing the cookies. Avoid putting them in the refrigerator to speed up the process, as condensation can make the icing damp or sticky. If you’re using a simple icing made with powdered sugar and lime juice, adding the liquid gradually helps you achieve a coating that dries more easily.

Can I substitute another citrus fruit for the lime in shortbread cookies?

Yes. Shortbread cookies can be made with different citrus fruits, allowing you to create variations without changing the overall character of the recipe too much. Lemon offers a delicate aroma and is less tart, while lime provides a more intense, refreshing flavor. Orange and mandarin also work very well, especially when the zest is used to flavor the dough. For a pronounced citrus flavor without adding too much liquid, use finely grated zest from the colored part of the peel. Avoid grating the white pith, which can make the cookies bitter. You can also substitute orange or mandarin juice for the lime juice in the icing, adjusting the amount until you reach the desired consistency.

Why are my lime shortbread cookies hard?

Lime shortbread cookies can become hard if too much flour is added, the dough is overworked, or the cookies spend too long in the oven. Since this type of cookie should have a delicate, slightly crumbly texture, small differences in the proportions can make a big difference. When adding the flour, mix only until a uniform dough forms; do not knead it. It’s also important to keep an eye on the oven: the cookies are usually ready when the edges begin to turn a light golden color. They may still seem a little soft when they come out of the oven, but they will firm up as they cool. For the best results, weigh the ingredients whenever possible and avoid adding extra flour just to make the dough easier to shape.

Can lime shortbread cookies be frozen?

Yes, both the dough and the baked lime shortbread cookies can be frozen. Wrap the raw dough well to prevent it from drying out or absorbing freezer odors. Another practical option is to freeze the shaped, unbaked cookies and bake them later, adding a few minutes to the baking time if needed. Baked cookies can also be frozen, but it’s best to do so before adding the icing, as the topping may change in texture and appearance during thawing. To serve, let the cookies thaw naturally at room temperature while still protected by their wrapping. Once they are completely thawed and dry, add the lime icing for a better finish.

What goes well with lime shortbread cookies with icing?

Lime shortbread cookies with icing pair especially well with drinks that balance their buttery texture and citrus flavor. Coffee, black tea, and green tea are classic choices, while chamomile or lemon balm infusions make for a more delicate pairing. For an afternoon tea spread, the cookies can also be served with fresh fruit, plain cakes, and other small desserts. To vary the presentation, try pairing them with coconut, white chocolate, pistachios, or almonds, using these sparingly so they don’t overpower the lime flavor. For parties and special occasions, the cookies can be decorated with lime zest sprinkled over the icing, creating a simple, fragrant, and visually appealing finish.
