This key lime cookie recipe transforms a classic pie flavor into irresistible stuffed cookies - the ultimate summer treat that balances tangy lime with creamy cheesecake filling in every bite.
I discovered this recipe last summer when looking for something different to bring to a beach picnic. The first batch disappeared in minutes, and now they're requested at every gathering from May through September.
Ingredients
- Cream cheese: Delivers that signature cheesecake filling texture look for full-fat varieties for the richest flavor
- Key lime juice and zest: Provide the essential tangy flavor fresh is always best but bottled works in a pinch
- Butter: Creates that perfect crisp-yet-tender cookie texture always use unsalted for better flavor control
- Combination of white and brown sugars: Adds complexity and moisture to the cookie base
- Vanilla extract: Balances the tartness of the lime with its warm flavor
Step-by-Step Instructions
- Prepare the filling:
- Create your key lime cheesecake filling by thoroughly mixing softened cream cheese with powdered sugar until completely smooth. Add the key lime zest and juice, being careful to avoid the bitter white pith when zesting. The filling should be creamy but firm enough to scoop.
- Freeze the filling:
- Scoop teaspoon-sized portions of filling onto parchment paper and freeze for at least 45 minutes until solid. This crucial step ensures your filling stays intact inside the cookies while baking and creates that perfect pocket of creaminess.
- Make the cookie dough:
- Cream together the butter, sugars, and lime zest until light and fluffy this typically takes 3-4 minutes of mixing to incorporate air for the perfect texture. Add the egg, vanilla, and lime juice, beating until just combined for a tender cookie.
- Add dry ingredients:
- Gently mix in the flour, baking soda, and salt just until no dry streaks remain overmixing will result in tough cookies. The dough should be soft but not sticky to the touch.
- Stuff the cookies:
- Scoop cookie dough into balls and create a small indentation in each. Press a frozen filling ball into each indentation, then carefully wrap and seal the dough around the filling. Ensure no filling is exposed to prevent leaking during baking.
- Bake to perfection:
- Bake one sheet at a time at 350°F for 9-12 minutes until the edges are just set and slightly golden. The centers will look slightly underdone but will continue cooking as they cool.

I especially love using local honey as a drizzle on these cookies right before serving. My grandmother taught me this trick during a summer visit to Florida, and the floral notes of the honey elevate the lime flavor in an unexpected way thats become my signature touch.
Storage Solutions
These cookies stay fresh in an airtight container at room temperature for up to 3 days, though the texture will soften over time. For longer storage, you can refrigerate them for up to a week, which actually enhances the cheesecake-like quality of the filling. If you want to freeze them, layer between parchment paper in a freezer-safe container for up to 3 months. Let them thaw overnight in the refrigerator before serving.
Ingredient Swaps
If youre in a pinch, regular limes work beautifully in place of key limes just know the flavor will be slightly less intense. For a dairy-free version, vegan cream cheese and plant-based butter substitute well, though the filling may need extra freezing time. White chocolate chips make a delicious addition to the cookie dough for extra sweetness, while toasted coconut can be folded in for tropical flair. For gluten-free friends, a cup-for-cup gluten-free flour blend works perfectly in this recipe.
Serving Suggestions
These cookies shine when served slightly chilled, which highlights the contrast between the cookie and filling. For an elegant dessert platter, dust them with powdered sugar and serve alongside fresh berries and mint sprigs. They pair wonderfully with iced tea or a citrus-infused sparkling water on hot days. For special occasions, sandwich vanilla ice cream between two cookies for an extraordinary ice cream sandwich, or crumble them over lime sorbet for a deconstructed key lime pie experience.

Frequently Asked Questions
- → Can I use regular limes instead of key limes?
Yes, regular limes can be substituted for key limes in this recipe. The flavor will be slightly different as key limes tend to be more aromatic and tart, but regular limes will still create a delicious cookie.
- → Why do I need to freeze the cheesecake filling?
Freezing the cheesecake filling makes it easier to handle when assembling the cookies. It helps prevent the filling from spreading during baking and ensures you get that distinct creamy center surrounded by cookie.
- → How do I properly measure flour for these cookies?
For best results, either weigh your flour using a kitchen scale or use the scoop and level method. The dough should be slightly more crumbly than typical cookie dough, but not dry. Using too much flour will result in dry cookies.
- → Can I make these cookies dairy-free?
Yes! The recipe notes that vegan cream cheese can be used for the filling. Just be sure to substitute dairy-free butter in the cookie dough as well for completely dairy-free cookies.
- → How should I store these cookies?
These cookies are best enjoyed fresh, but can be stored in an airtight container in the refrigerator for 3-4 days. They can also be frozen in a ziplock bag and thawed in the refrigerator when you're ready to enjoy them.
- → Why is it important to avoid the lime pith?
The white part of the lime (pith) is very bitter. Including it when zesting would make your cookies extremely bitter and affect the overall flavor negatively.
