- 3 cups all-purpose flour

How to Make Key Lime Cookies
Whip up a batch of these incredibly easy, yet astonishingly delicious key lime cookies, perfectly tangy and sweet. In under 20 minutes of prep and about 10-12 minutes of baking per batch, you'll have delightful cookies that are bursting with bright citrus flavor and have a wonderfully tender, slightly chewy texture. They're the ideal make-ahead treat for any gathering or just a delightful afternoon indulgence.
Step-by-Step Instructions
- Cream the butter and sugar: In a large mixing bowl, beat the softened unsalted butter and granulated sugar together with an electric mixer on medium speed until light and fluffy, about 3-4 minutes. This creaming process incorporates air, which is crucial for cookie texture.
- Add wet ingredients: Beat in the room temperature eggs, one at a time, until well combined after each addition. Next, stir in the fresh key lime juice, key lime zest, and vanilla extract. The mixture might look slightly curdled at this point, which is normal.
- Combine dry ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking powder, and salt. This ensures the leavening and salt are evenly distributed throughout the dough.
- Combine wet and dry: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix at this stage, as it can lead to tough cookies.
- Chill the dough: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes, or up to 2 days. Chilling the dough makes it easier to handle and prevents the cookies from spreading too much during baking, ensuring a cleaner shape.
- Preheat oven and prepare baking sheets: Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper to prevent sticking and ensure even baking.
- Scoop the dough: Roll the chilled dough into 1-inch balls. You can use a cookie scoop for uniform size. Place the dough balls about 2 inches apart on the prepared baking sheets.
- Bake the cookies: Bake for 10-12 minutes, or until the edges are lightly golden and the centers are still slightly soft. The cookies will continue to set as they cool on the baking sheet.
- Cool the cookies: Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This is important for them to firm up.
- Prepare the glaze: While the cookies are cooling, whisk together the powdered sugar and 2 tablespoons of key lime juice in a small bowl until smooth. Add more key lime juice, a teaspoon at a time, if a thinner glaze is desired. Stir in the optional key lime zest if using.
- Glaze the cookies: Once the cookies are completely cool, dip the tops into the key lime glaze, or drizzle the glaze over the tops using a spoon or piping bag. Let the glaze set completely on a wire rack.

Storing and Reheating Tips
For optimal freshness, ensure your completely cooled key lime cookies are stored in an airtight container at room temperature. They will stay deliciously fresh for up to 5 days. If you find you have more cookies than you can enjoy within that window, you can also freeze them. For freezing, place the cooled cookies in a single layer on a baking sheet and freeze until solid, then transfer them to a freezer-safe bag or container. They can be stored in the freezer for up to 3 months. To enjoy frozen cookies, simply let them thaw at room temperature for about 30 minutes. Reheating is not generally recommended as it can alter the cookie's texture, but if you prefer a slightly warm cookie, you can warm them in a low oven (around 200°F or 95°C) for a few minutes, though this is best done just before serving.
