Crumbl Copycat Key Lime Pie Cookies

Crumbl copycat key lime pie cookies are one of those recipes I just had to crack at home and trust me, they turned out even better than I expected. If you’ve ever bitten into one of those oversized, gorgeous Crumbl cookies and thought, “I wish I could make this myself,” you’re in the right place.

I actually got the idea one Saturday afternoon when Isabella and Emma were begging for a dessert run. Instead of packing everyone into the car, I decided to try making them right in my own kitchen. Henry was skeptical at first but after one taste, he was asking for seconds. Now these have become a staple in our house, and I get so many requests to share the recipe!

What You Need to Make These Key Lime Cream Cheese Cookies

Here’s everything you’ll need for this recipe. Nothing too fancy just good, simple ingredients.

For the Cookie Dough:

• 1/2 cup unsalted butter, softened (not warm!)
• 2 tablespoons cream cheese, softened
• 1/2 cup brown sugar
• 1/3 cup white sugar
• 1 large egg
• 1 teaspoon vanilla extract
• 1 3/4 cups all-purpose flour
• 1 teaspoon cornstarch
• 1 teaspoon baking powder
• 1/4 teaspoon baking soda
• 1 teaspoon salt
• 2/3 cup graham cracker crust, crushed (for rolling)
• 3/4 cup graham cracker crust, broken into small chunks

For the Key Lime Filling:

• 6 ounces cream cheese, softened
• 1 tablespoon sour cream
• 1/2 cup sweetened condensed milk
• 1 tablespoon lime zest
• 1/4 cup lime juice
• Lime wedges (for topping)
• Whipped cream (for topping)

Swap tip: Can’t find key limes? Regular limes work just as well. The flavor is still bright and tangy no one will know the difference.

Follow these steps carefully and you’ll end up with bakery-perfect cookies every single time.

1. Preheat your oven to 350°F and line two baking sheets with parchment paper.
2. Cream the butter in a large mixing bowl until smooth. Add the 2 tablespoons of softened cream cheese and cream together until fully combined.
3. Add the sugars and beat on medium speed for about 1 minute until light and fluffy. Scrape down the sides of the bowl, then mix in the egg and vanilla until just combined.
4. Whisk the dry ingredients together in a separate bowl that’s the flour, cornstarch, baking powder, baking soda, and salt. No graham cracker chunks yet.
5. Fold in the dry mix. Pour it into the wet ingredients and mix until about half the flour is incorporated. Then switch to a wooden spoon and gently fold in the graham cracker chunks. Don’t overmix stop as soon as the dough comes together.
6. Scoop and roll. Use a large cookie scoop to make 8–10 big cookie balls. Roll each one in the crushed graham cracker crust, then place 4 at a time on your prepared baking sheet.
7. Make a well. Press a tablespoon into the center of each dough ball to create an indent. Bake for 10 minutes.
8. Re-indent while hot. Pull them from the oven and immediately press the center again using a small glass or measuring cup. This makes the perfect little pocket for the filling. Let them cool completely.

Making the Key Lime Filling

9. Beat the cream cheese in a bowl until soft and smooth. Add the sour cream, sweetened condensed milk, lime zest, and lime juice. Beat again until everything is creamy and well mixed.
10. Fill the cookies. Spoon the filling into the center of each cooled cookie. Don’t be shy pile it on a little!
11. Chill for 2 hours. Pop the cookies in the fridge until the filling is set and firm. This step is important trust me on this one.
12. Top and serve. Right before serving, add a small dollop of whipped cream and a tiny lime wedge on each cookie. That’s the move that makes these look absolutely stunning.

How to Store These Chilled Key Lime Cookies

These cookies need to stay cold to hold their shape, so keep them in the fridge at all times after the filling is added.

Store them in an airtight container in the refrigerator for up to 4 days. Layer parchment paper between cookies so they don’t stick together.

Freezing works too but only freeze the cookie bases without the filling. Once you’re ready to serve, thaw them out and add the fresh filling and toppings. This keeps everything tasting its best.

Tips and Variations for Bakery Style Key Lime Cookies

Want to switch things up a bit? Here are a few ideas that work really well:

• Make them smaller. Use a medium cookie scoop instead of a large one for bite-sized versions. Great for cookie trays and gift boxes.
• Add a drizzle. A light drizzle of white chocolate over the top looks gorgeous and adds a little extra sweetness.
• Skip the whipped cream. If you’re not a big whipped cream fan, a simple sprinkle of crushed graham crackers on the filling looks just as pretty.
• Use store-bought graham cracker pie crust. Crumble it up yourself it gives you that perfect texture without any extra work.

One thing to watch out for: make sure your butter is softened, not melted. Melted butter will make the dough too thin and the cookies won’t hold their shape. Simply put, room temperature butter is the way to go here.
