Ingredients You'll Need
The beauty of this Key Lime Pie Cookies (Gluten Free) Recipe lies in its simply perfect ingredients. Each one has a crucial role—whether that's infusing brightness, creating the right texture, or adding a creamy richness—resulting in a cookie that's both flavorful and satisfying.
- Gluten free graham cracker crumbs (1 cup, 108g): The base for our cookie's crumbly texture and that classic graham flavor.
- Gluten free 1-to-1 flour (1 ¼ cup, 150g): Keeps this recipe gluten free while giving structure to the cookies; can swap with AP flour if not gluten sensitive.
- Kosher salt (½ tsp): Enhances all the flavors and balances the sweetness perfectly.
- Baking powder (½ tsp) & baking soda (¼ tsp): These leavening agents help the cookies rise just enough without losing their tender crumb.
- Cane sugar (¼ cup, 50g): Adds light sweetness that complements the lime zest beauty.
- Brown sugar (¼ cup, 50g): Brings a slight caramel note and moisture to the dough.
- Key lime zest (1 tbsp): This zest is pure magic, bursting with citrus oils that give the cookies their signature tang.
- Unsalted butter (½ cup, 113g): At room temperature but not fully soft, it delivers richness and tenderness.
- Large egg (1): Binds the dough while adding a bit of lift.
- Fresh key lime juice (1 tablespoon + 2 tablespoon separately): The heart of the recipe’s bright, tart flavors, used both in dough and filling.
- Vanilla extract (1 teaspoon + ½ teaspoon separately): Adds warmth and rounds out the citrusy notes beautifully.
- Full-fat plain Greek yogurt (½ cup + 2 tbsp, 5oz): Lends creaminess and moisture to the filling, making it irresistibly smooth.
- Sweetened condensed milk (⅓ cup): Delivers a luscious, sweet base in the filling that echoes the classic pie’s richness.
- Key lime slices and extra key lime zest: For garnish—adding fresh color and that extra zing on top.
How to Make Key Lime Pie Cookies (Gluten Free) Recipe
Step 1: Whip Up the Key Lime Filling
Start by combining all the filling ingredients in a medium bowl—Greek yogurt, sweetened condensed milk, fresh lime juice, zest, vanilla, and a pinch of salt. Whisk them together until smooth and well mixed. Pop it into the fridge to chill and thicken while you work on your cookies. This step gives the filling time to develop that perfect creamy tang.
Step 2: Prepare Your Oven and Dry Ingredients
Preheat your oven to 350°F and line your baking sheets with parchment paper to keep the cookies from sticking. Then, whisk together the gluten free graham cracker crumbs, gluten free flour, kosher salt, baking powder, and baking soda in a bowl. This blend creates the foundation for your cookie dough, ensuring lightness and structure despite the lack of gluten.
Step 3: Cream Sugar, Zest, and Butter
In a large bowl, mix together cane sugar, brown sugar, and key lime zest. Use your fingers to massage the zest into the sugar to release those aromatic oils—this little trick packs an incredible punch of flavor. Next, add the butter and beat the mixture for about two minutes until it’s fluffy and light. This step ensures the cookies stay tender.
Step 4: Combine Wet and Dry Ingredients
Add the egg, key lime juice, and vanilla extract to your butter and sugar mixture and beat for another minute. It might look a bit loose or uneven—don’t worry, this is just how it should look. Finally, add your bowl of dry ingredients and fold everything together with a spatula until just combined. Don’t overmix—gentle folding keeps your cookies tender and soft.
Step 5: Shape and Create Wells in the Dough
Now for the fun part: scoop 1.5 tablespoons of dough and roll into balls, spacing them at least 2 inches apart on your parchment-lined baking sheets. Use the back of a rounded tablespoon or your thumb to press a deep well into the center of each dough ball—spraying the spoon with a little cooking spray helps prevent sticking. These wells will hold all that luscious filling later.
Step 6: Bake and Re-Shape
Bake your cookies for about 12 minutes. You’ll notice they puff up in the oven, but don’t worry about that. The moment they come out, press the back of your spoon into the center wells again to re-establish the indentation. This step is key to giving your cookies that authentic filled look. Let them cool on the baking sheet for five minutes before transferring to a wire rack.
Step 7: Fill, Garnish, and Enjoy
Once the cookies are completely cooled, spoon about a tablespoon of the chilled key lime filling into each well and spread it evenly with a small knife or offset spatula. For the final, beautiful touch, garnish with a fresh key lime slice and a sprinkle of key lime zest. These treats taste best chilled but are also wonderful eaten right away. Enjoy every tangy-sweet bite!
How to Serve Key Lime Pie Cookies (Gluten Free) Recipe
Garnishes
Beyond the simple fresh key lime slice and zest, you can jazz these cookies up with a tiny mint leaf or a dusting of powdered sugar for an elegant look. A little edible flower could also make them feel extra special if you’re serving guests.
Side Dishes
Pair these cookies with a cup of freshly brewed coffee or a light, citrusy iced tea to complement their tartness. They’re also wonderful alongside a scoop of vanilla bean ice cream for an indulgent dessert plate.
Creative Ways to Present
Arrange your Key Lime Pie Cookies (Gluten Free) Recipe on a sunny platter with tropical leaves or serve stacked with parchment paper between layers for a charming gift. You can even skew one on a decorative stick to create quirky, handheld cookie pops for a party display.
Make Ahead and Storage
Storing Leftovers
Store any leftovers in an airtight container in the fridge. They’ll keep well for up to 4 days, maintaining that creamy filling without drying out the cookie. Just bring them back to room temperature before serving for best flavor.
Freezing
If you want to make these ahead for a special occasion, freeze the cookies without filling for up to 3 months. After thawing, add the chilled filling and garnish to keep everything fresh and vibrant. This way, your Key Lime Pie Cookies (Gluten Free) Recipe stays crisp and creamy at serving time.
Reheating
Since these cookies taste best chilled or at room temperature, reheating isn’t necessary. But if you prefer them slightly warm, pop them in a 300°F oven for 3-4 minutes—just not with the filling. Add the filling after warming to avoid melting or separating.
FAQs
Can I use regular lime instead of key lime?
Absolutely! While key limes offer a unique aroma and tartness, regular limes will still provide that fresh citrus zing. You might find the flavor slightly less intense but delicious nonetheless.
Is there a dairy-free substitution for the Greek yogurt?
Yes, you can swap with a thick coconut yogurt or another plant-based yogurt. Just make sure it’s unsweetened and full-fat to get a similar creamy texture in the filling.
Can I double the recipe for a larger batch?
Definitely! The recipe scales up nicely—just be sure to space the cookies well on your baking sheets to allow them room to spread and rise properly.
Why do I need to press the well twice?
Cookies puff up while baking, filling in the indentation. Pressing the wells again right after baking creates the perfect hollow to hold the creamy filling, ensuring you get that signature filled cookie experience.
Can I make these cookies without sweetened condensed milk?
The condensed milk adds signature richness and sweetness to the filling, but you can try using a mix of evaporated milk and extra sugar as a substitute. Keep in mind the texture and sweetness may vary slightly.

- Preheat Oven and Prepare Baking Sheets: Preheat your oven to 350°F (177°C). Line an extra-large baking sheet (21x15") or two standard baking sheets with parchment paper to prevent sticking and ensure easy cleanup.
- Mix Dry Ingredients: In a medium bowl, combine gluten free graham cracker crumbs, gluten free 1-to-1 flour, kosher salt, baking powder, and baking soda. Whisk until fully blended and set aside.
- Combine Sugars and Zest: In a large bowl or stand mixer bowl, add cane sugar, brown sugar, and key lime zest. Massage the zest into the sugars with your hands to release aromatic oils, enhancing flavor.
- Cream Butter and Sugars: Add room temperature butter to the sugar mixture. Beat with a hand or stand mixer for about 2 minutes until it becomes fluffy and light in texture.

Notes
- For best results with the gluten free graham cracker crumbs, use a brand that is finely ground to achieve a smooth cookie texture.

- Butter should be at room temperature but not overly soft to ensure proper creaming and texture.
- If the dough feels too sticky when shaping, lightly oil your hands or utensils to help handle better.
- Chilling the key lime filling allows it to thicken, making it easier to fill the cookie wells without running.
- Store assembled cookies in the refrigerator to keep the filling firm and fresh.
