Ingredients

To create about 24–30 cookies, gather the following ingredients:

For the Cookies:

• 1 cup (226g) unsalted butter, softened
• 1 cup (200g) granulated sugar
• 2 large eggs
• 2 tablespoons fresh key lime juice
• 1 tablespoon key lime zest (around 4–5 key limes)
• 2¾ cups (345g) all-purpose flour
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ¼ teaspoon salt

Optional Glaze:

• 1 cup powdered sugar
• 1–2 tablespoons key lime juice
• Extra lime zest for garnish (optional)

Step-by-Step Instructions

Step 1: Prep Your Ingredients: Before starting, zest and juice your key limes. If you can’t find key limes, regular limes work well too, though the flavor will be slightly less intense. Also, preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

Step 2: Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This usually takes 2–3 minutes with an electric mixer on medium speed.

Step 3: Add Wet Ingredients: Add in the eggs one at a time, mixing well after each addition. Then pour in the key lime juice and zest. The mixture may look slightly curdled—this is normal due to the acidity from the lime juice.

Step 4: Mix Dry Ingredients Separately: In another bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry mixture into the wet mixture, mixing until just combined. Be careful not to overmix, as that can make the cookies tough.

Step 5: Shape and Bake: Using a cookie scoop or spoon, drop rounded tablespoons of dough onto your prepared baking sheets, spacing them about 2 inches apart. Bake for 10–12 minutes, or until the edges are lightly golden. The centers may look slightly underdone, but they’ll set as they cool.

Step 6: Cool and Glaze: Let the cookies rest on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. If using the glaze, whisk together the powdered sugar and key lime juice until smooth, then drizzle or spoon it over cooled cookies. Finish with a sprinkle of lime zest for an extra pop.

Tips for Success

1. Use Fresh Key Lime Juice: Bottled juice can be convenient, but freshly squeezed key lime juice gives a brighter, more natural flavor.
2. Zest Before Juicing: Always zest your limes before cutting and squeezing them. It’s much easier this way.
3. Don’t Overbake: These cookies are meant to be soft and chewy. Overbaking can make them dry and cakey.
4. Chill the Dough (Optional): For thicker cookies, chill the dough for 30 minutes before baking.
5. Make It Your Own: Add white chocolate chips, shredded coconut, or crushed graham crackers for a creative twist.

Serving and Storing

These cookies are best served fresh, but can be stored in an airtight container at room temperature for up to 5 days. They also freeze well—just let them cool completely and freeze them in a single layer before transferring to a freezer-safe bag.
