Key Lime Pie Cookies
Buttery, soft-baked cookies packed with bright citrus flavor and a creamy graham cracker crunch that tastes just like your favorite summer pie.
Imagine biting into a soft, chewy cookie and getting hit with that unmistakable zing of fresh key lime, followed by a rich, creamy sweetness and the warm crunch of graham cracker. These Key Lime Pie Cookies are everything you love about a classic key lime pie, packed into a handheld treat that disappears from the cookie jar faster than you can say 'one more.' The edges are ever so slightly crisp, the centers stay pillowy and tender, and the lime glaze on top adds just the right amount of tang to make your taste buds sing.
These cookies are perfect for warm-weather gatherings, potlucks, bake sales, or any time you want to bring a little sunshine to the table without firing up a whole pie crust. They come together in under an hour, and unlike pie, you can pop them in a bag and take them anywhere. They're just as welcome at a casual backyard barbecue as they are on a fancy dessert tray at a summer bridal shower.
I first made these on a whim during a hot July afternoon when I had a whole bag of key limes sitting on my counter and zero motivation to make an actual pie. One batch in, and my family was hooked. Now they're a regular request at every gathering, and I always make a double batch because the first one never makes it to the party.

Step-by-Step Instructions
Prep Your Workspace
Preheat your oven to 350 degrees Fahrenheit and line two large baking sheets with parchment paper or silicone baking mats. Set them aside while you prepare the dough. Pull your butter, cream cheese, and eggs out of the fridge at least 30 minutes ahead of time so everything is genuinely at room temperature, which helps the dough come together smoothly without overmixing.
Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt until evenly combined. Stir in the graham cracker crumbs so they are fully incorporated into the flour mixture. Setting this aside now means you can add it all at once later without overworking the dough.
Cream Butter and Sugars
In a large mixing bowl using a hand mixer or a stand mixer fitted with the paddle attachment, beat the softened butter, granulated sugar, and brown sugar on medium-high speed for about 3 minutes. You want the mixture to look pale, fluffy, and noticeably increased in volume. This step is important because it builds the light, tender texture of the final cookie, so don't rush it.
Add Cream Cheese and Wet Ingredients
Add the softened cream cheese to the butter mixture and beat for another minute until fully blended and smooth. Scrape down the sides of the bowl, then add the whole egg, egg yolk, vanilla extract, key lime juice, and key lime zest. Mix on medium speed until everything is combined and the batter looks slightly curdled, which is completely normal at this stage. The flour will bring it all together.
Combine Wet and Dry
With the mixer on low speed, gradually add the flour and graham cracker mixture to the wet ingredients. Mix just until no dry streaks remain. Be careful not to overmix at this point, as that can lead to tough, dense cookies. The dough will be soft and slightly sticky, which is exactly what you want.
Portion the Cookies
Using a medium cookie scoop or a heaping tablespoon, portion the dough into balls roughly 1.5 inches in diameter and place them about 2 inches apart on your prepared baking sheets. If the dough feels too sticky to handle, refrigerate it for 15 to 20 minutes before scooping. Gently press each ball down just slightly with the palm of your hand to help them spread evenly during baking.
Bake to Golden Perfection
Bake the cookies for 11 to 13 minutes, rotating the baking sheets halfway through, until the edges are just set and the centers look slightly underdone. They will firm up as they cool, so pulling them out while the center looks a little soft is the key to that pillowy texture. Avoid overbaking, as these cookies can dry out quickly past the 13-minute mark.
Cool the Cookies
Let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire cooling rack. This resting time helps them finish setting up without falling apart. Allow them to cool completely before glazing, usually about 20 to 25 minutes. Glazing warm cookies causes the icing to run right off and pool at the bottom.
Make the Key Lime Glaze
While the cookies cool, whisk together the sifted powdered sugar, fresh key lime juice, key lime zest, and a pinch of salt in a small bowl. Start with 2 tablespoons of juice and add more a little at a time until you reach a thick but pourable consistency, similar to a slow drizzle. You want it to coat a spoon and hold its shape for a moment before flowing.
Glaze and Garnish
Once the cookies are fully cooled, use a spoon or a small squeeze bottle to drizzle or spread the glaze over each cookie. Immediately sprinkle a small pinch of graham cracker crumbs and a little extra lime zest on top of each glazed cookie before the icing sets. The garnish adds texture and makes them look bakery-worthy with almost zero extra effort.
Let the Glaze Set
Allow the glaze to set at room temperature for about 15 to 20 minutes before stacking or storing the cookies. The glaze will firm up to a soft, slightly matte finish. If you're in a hurry, you can place the glazed cookies in the refrigerator for 10 minutes to speed things up.
