Ingredients
Let’s talk about what goes into these Key Lime Pie Cookies—each ingredient has a role in bringing those zesty, sweet flavors together into cookie perfection.
- All-Purpose Flour: The base of your dough. It creates the soft, chewy texture we love in cookies. It helps hold everything together while allowing the lime to shine through.
- Baking Soda: This little leavening agent gives the cookies that perfect rise and fluffiness, so they’re not too dense. It helps create a light, melt-in-your-mouth texture.
- Salt: A pinch of salt balances out the sweetness and enhances all the flavors, especially that tangy lime.
- Unsalted Butter: Butter makes everything better! It creates a rich, smooth texture and gives the cookies that buttery flavor we all crave.
- Granulated Sugar: This sweetener helps create the cookie’s chewy consistency and the perfect amount of sweetness to balance the tart lime.
- Egg: The egg helps bind the dough together and gives the cookies a soft texture. It also helps with the cookies’ golden color.
- Key Lime Juice: This is the star! Freshly squeezed key lime juice (or regular lime juice if you can’t find key limes) provides that signature tangy citrus flavor that makes these cookies so irresistible.
- Lime Zest: For an extra punch of lime flavor, we’ll add the zest. It adds freshness and makes each bite even more refreshing.
- Graham Cracker Crumbs: These give the cookies that classic key lime pie crust flavor. The buttery, crunchy bits in every bite will make you feel like you’re eating an actual key lime pie.

Instructions
Let’s dive into how to make these irresistible Key Lime Pie Cookies, step by step:
1. Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This ensures that the cookies bake evenly and come out perfectly golden and chewy.
2. Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set this bowl aside for later.
3. Cream the Butter and Sugar
In a separate large bowl, beat the unsalted butter and granulated sugar together until it’s light and fluffy. This should take about 2-3 minutes with an electric mixer. The air you whip into the butter will make your cookies extra tender.
4. Add the Wet Ingredients
Next, add the egg, key lime juice, and lime zest to the butter mixture. Mix until well combined. The lime juice will add that tangy kick we’re all after, while the zest adds depth and freshness to the flavor.
5. Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix—this helps keep your cookies soft and chewy.
6. Add the Graham Cracker Crumbs
Stir in the graham cracker crumbs. This is what gives your cookies that iconic key lime pie crunch! The crumbs should be evenly distributed throughout the dough.
7. Scoop the Dough
Use a cookie scoop or tablespoon to drop dough onto a parchment-lined baking sheet. Space the dough balls about 2 inches apart to give them room to spread.
8. Bake the Cookies
Bake the cookies for 10-12 minutes, or until they’re lightly golden around the edges. They’ll firm up as they cool, so don’t worry if they’re still a little soft in the center when you take them out.
9. Let Cool
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
10. Serve and Enjoy
Once they’re fully cooled, these cookies are ready to enjoy! Serve them with a cold glass of milk, or a hot cup of tea—either way, they’re sure to be a hit!

- Make the Cookies Smaller: If you prefer bite-sized treats, scoop smaller portions of dough and bake for about 8-10 minutes.
- Storage Tips: Store these cookies in an airtight container at room temperature for up to a week. You can also freeze the dough for up to 3 months. Just scoop the dough into balls and freeze them. Bake from frozen—just add a minute or two to the baking time.
