I recently baked this Key Lime Pie Sandwich Cookies Recipe, and they instantly became one of my favorite citrus desserts. The cookies have that classic graham cracker flavor, while the filling is creamy, tangy, and perfectly sweet.
When I took the first bite, it honestly reminded me of a slice of key lime pie—but in cookie form. I love how soft the cookies are with a bright lime filling in the middle. If you enjoy refreshing desserts with a little zing, this recipe is definitely worth trying.

Ingredients
These cookies use simple pantry ingredients, but the combination creates a perfect balance of buttery cookies and creamy citrus filling.
For the Graham Cracker Cookies
- ¾ cup all‑purpose flour – Measure carefully by fluffing and spooning the flour into the cup, then leveling it off. This prevents dense cookies.
- ¾ cup graham cracker crumbs – These give the cookies their signature “key lime pie crust” flavor and light crunch.
- ¼ teaspoon ground cinnamon – Adds subtle warmth that complements the citrus flavor.
- ¼ teaspoon baking powder – Helps the cookies rise slightly and keeps them soft.
- ½ teaspoon baking soda – Provides lift and creates a tender texture.
- ½ cup unsalted butter, softened – Room‑temperature butter blends smoothly with sugar for a creamy dough.
- ½ cup granulated sugar (plus extra for rolling) – Adds sweetness and creates a light crisp coating when the dough balls are rolled in sugar.
- ½ teaspoon vanilla extract – Enhances the flavor of the cookies without overpowering the lime.
- 1 egg yolk – Gives the cookies richness and a soft texture.
For the Key Lime Cream Cheese Filling
- 8 oz cream cheese, softened – The base of the filling that provides smoothness and creamy texture.
- ½ cup powdered sugar – Sweetens the filling while keeping it silky and lump‑free.
- 1 tablespoon key lime zest – Provides intense citrus aroma and flavor.
- 1 tablespoon key lime juice – Adds the signature tart taste that makes these cookies taste like key lime pie.
Note: This ingredient quantity makes about 12 sandwich cookies (24 individual cookies). You can also enjoy similar Garlic Parmesan Roasted Chickpeas Recipe for a savory snack that pairs well with citrus desserts.

How to Make Key Lime Pie Sandwich Cookies Recipe?
These cookies come together quickly and are perfect for beginners. The process involves baking soft graham‑flavored cookies and filling them with a creamy lime frosting.
Step 1: Prepare the Oven and Baking Sheets
Start by preheating your oven to 375°F (190°C). Line baking sheets with parchment paper or silicone baking mats to prevent sticking and ensure even baking. This preparation step also makes cleanup much easier.
Step 2: Cream the Butter and Sugar
In a mixing bowl, beat the softened butter and granulated sugar together until light and creamy. Add the vanilla extract and egg yolk, then mix until the ingredients are fully combined and smooth.
Step 3: Combine the Dry Ingredients
In another bowl, whisk together the flour, graham cracker crumbs, cinnamon, baking powder, and baking soda. Mixing the dry ingredients first ensures the leavening agents distribute evenly throughout the dough.
Step 4: Form the Cookie Dough
Slowly mix the dry ingredients into the wet mixture until a dough forms. At first, the dough might seem crumbly, but continue mixing for about one to two minutes until it comes together into a soft, workable dough.
Step 5: Shape and Coat the Cookies
Roll the dough into small balls about one inch in size. Roll each dough ball in granulated sugar so the outside gets a light sugary coating before baking.
Step 6: Bake the Cookies
Place the dough balls onto the prepared baking sheets and bake for about 6–7 minutes until the bottoms are lightly golden brown. Let them cool on the tray for a few minutes, then transfer to a wire rack to cool completely.
Step 7: Make the Key Lime Filling
In a bowl, beat the softened cream cheese until completely smooth. Add powdered sugar and mix until incorporated, then blend in the lime zest and lime juice for a bright citrus flavor.
Step 8: Assemble the Sandwich Cookies
Spread about one tablespoon of the cream cheese mixture onto the bottom of a cooled cookie. Place another cookie on top to form a sandwich, gently pressing them together before serving.
Additional Tips for Making This Recipe Better
After making these cookies several times, I discovered a few simple tricks that really improve the texture and flavor.
- I always measure flour carefully using the spoon‑and‑level method to avoid dense cookies.
- I like chilling the filling for about an hour if I want it to be thicker and easier to spread.
- I sometimes add extra lime zest because I personally love a stronger citrus flavor.
- I try not to assemble the sandwiches too early; I fill them just before serving to keep the cookies from getting too soft.
