Step‑by‑Step Instructions for Key Lime Cookies
Step 1: Prepare Ingredients
Begin by zesting and juicing 8 key limes, ensuring to capture all the vibrant citrus goodness. Next, chop ¾ cup of gluten-free graham crackers into small pieces that will add delightful crunch to your Key Lime Cookies. Set these ingredients aside to incorporate later into the cookie batter.
Step 2: Mix Dry Ingredients
In a medium mixing bowl, whisk together 2 cups of gluten-free flour, 1 teaspoon of baking powder, and ½ teaspoon of kosher salt. This dry mixture will form the base of your Key Lime Cookies. Make sure to blend them thoroughly, so the baking powder and salt are evenly distributed for a perfect rise during baking.
Step 3: Cream Butter and Sugar
Using an electric mixer, cream together ½ cup of unsalted butter (or a vegan baking stick) and 1 cup of granulated sugar in a large bowl. Beat this mixture on medium speed until it becomes light and fluffy, which should take about 3-5 minutes. This step is key for adding richness and ensuring your cookies have a delightful texture.
Step 4: Combine Ingredients
Gradually mix in ½ cup of sweetened condensed milk, along with the zest and juice of the key limes. Continue to blend everything until fully incorporated. You’ll notice a smooth, creamy batter forming, enriched with the fragrant essence of key lime, ready to be transformed into delicious cookies.
Step 5: Incorporate Dry Mixture
Gently fold the dry ingredient mixture into the wet ingredients using a spatula, mixing just until combined. Be careful not to over-mix as this can affect the tenderness of your Key Lime Cookies. After the dough is formed, softly fold in the chopped graham crackers for that added crunch.
Step 6: Chill Dough
Cover the cookie dough with plastic wrap and refrigerate it for at least 1 hour. Chilling the dough is crucial as it helps prevent the cookies from spreading too much while baking. This time allows the flavors to meld, resulting in wonderfully tender cookies.
Step 7: Preheat Oven
Once the dough is chilled, preheat your oven to 325°F (160°C). While the oven heats, scoop the dough and form it into discs, flattening them slightly. For a fun twist, roll the edges in a mix of key lime zest and sugar to enhance the cookies' vibrant flavor.
Step 8: Bake
Line a baking sheet with parchment paper and place the cookie discs on it, ensuring they are spaced apart. Bake the cookies for about 8 minutes, or until the edges turn a beautiful golden brown. This indicates they are perfectly baked, soft in the center, and deliciously chewy.
Step 9: Cool & Glaze
After baking, let the cookies cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This cooling period helps them set perfectly. Once cooled, top each cookie with graham cracker chunks and drizzle the cream cheese glaze over them, enhancing their charm and flavor.

Make Ahead Options
These Key Lime Cookies are perfect for meal prep, allowing you to savor their zesty delight even on the busiest days! You can prepare the dough up to 24 hours in advance by covering and refrigerating it, which helps the flavors meld beautifully. For longer storage, shape the unbaked cookie dough into discs and freeze them for up to 30 days; just make sure to wrap them in plastic wrap to prevent freezer burn. When you’re ready to enjoy your cookies, simply bake from frozen for an extra minute or two. You'll get the same tender, chewy texture and refreshing flavor, making your dessert experience just as delicious with minimal effort!

Key Lime Cookies Recipe FAQs
How do I select ripe key limes?
Absolutely! When selecting key limes, look for ones that are small, smooth, and firm, with a vibrant green color. They should feel heavy for their size, indicating juiciness. Avoid any limes with dark spots or wrinkles, as these can indicate over-ripeness or spoilage.
What is the best way to store Key Lime Cookies?
These cookies perform best when stored in an airtight container at room temperature for up to 3 days. Keep them away from direct sunlight to maintain their freshness. If you want to keep them longer, refrigerate them in a sealed container for up to 5 days; this can actually enhance their flavors!
Can I freeze the cookie dough for later use?
The more the merrier! You can definitely freeze your unbaked Key Lime Cookies dough. Simply wrap it tightly in plastic wrap and place it in a freezer bag. It will stay fresh for up to 30 days. When you’re ready to bake, just thaw in the refrigerator overnight and proceed with the baking instructions as normal!
What do I do if my cookies spread too much during baking?
Oh no, that can happen sometimes! To avoid excessive spreading during baking, make sure to chill your dough for at least 1 hour. If this happens, you can reduce the baking time slightly or make sure to scoop your dough into taller mounds instead of flattening them too much before baking.
Are Key Lime Cookies safe for those with allergies or dietary restrictions?
Very much so! These cookies are gluten-free, nut-free, and eggless, making them a great option for various dietary needs. However, always check your ingredients, especially the graham crackers and sweetened condensed milk, to ensure they meet your specific dietary requirements. If you have concerns about cross-contamination, consider using certified gluten-free products.
How long do Key Lime Cookies remain fresh after baking?
Typically, you can expect these cookies to remain delicious for about 3 days at room temperature. If stored properly in an airtight container, they retain their delightful chewiness and zesty flavor. For the freshest taste, I often recommend enjoying them within the first couple of days!
