Key Ingredients in Key Lime Cookies

• Butter, Eggs, Oil, and Sugar: I am using salted butter here, and blending it with canola oil, 2 eggs, and both white and brown sugar. The dough for these cookies comes together like a brownie recipe might, where you mix wet ingredients all at once, and then mix in the dry ones.
• Vanilla Extract: All good cookie recipes include a little bit of this. Always choose pure vanilla extract over any imitations.
• Flour, Cornstarch, Baking Soda, and Salt: The dry ingredients. Cornstarch is added to give the key lime pie cookie “crust” a crisp yet chewy texture.
• Graham Cracker Crumbs: This recipe uses finely ground graham crackers to replace what would typically be more flour, to make little graham cracker crust cookies for our key lime filling. The best way to make graham cracker crumbs is in a food processor.
• Key Lime Pie Filling: To fill the crusts, we’ll blend together heavy whipping cream, softened cream cheese, sweetened condensed milk, sour cream, and fresh lime juice. Don’t stress about looking for key limes. Regular lime juice is perfect.
• Garnishes: Each cookie is topped with fresh whipped cream, graham cracker crumbs, lime wedges, and lime zest.

How to Make Crumbl Key Lime Pie Cookies

1. Get Ready: Preheat the oven to 325°F/165°C. Line a sheet pan with parchment paper, and lay out the mini tart pans on it.
2. Make the Cookie Dough: In the bowl of a stand mixer, add the butter, sugar, brown sugar, oil, vanilla extract, and eggs. Beat until the mixture becomes light and fluffy. Then add the flour, 1 ½ cups of graham cracker crumbs, cornstarch, baking powder, and salt to the bowl. Beat again on medium speed until everything is combined into a dough.
3. Coat in Crumbs: Pour the remaining 1 cup of graham cracker crumbs into a shallow bowl. Create ¼ cup sized balls of dough, and roll each ball into the graham cracker crumbs before placing it in one of the tart tins.

3. Shape the Cookies: Use the flat bottom of a cup or measuring cup to flatten the balls of dough into the din, pushing deep enough to create a cavity. If you’d rather not use the tins, do the same thing, but shape the dough into a pie crust shape with your fingers. If you find that the cup is sticking to the dough, dip it in graham cracker crumbs.
4. Bake: Bake for 12-15 minutes or until lightly golden. Remove from the oven and let cool on the cookie sheet while you make the filling.

5. Make Key Lime Filling: Start by whipping the heavy whipping cream in a stand mixer until it has reached stiff peaks. Scrape the whipped cream into another bowl and set aside. Then add the softened cream cheese and beat it on medium-high until smooth. While the mixer is running, slowly stream in the sweetened condensed milk. Next, add the lime juice and beat for a couple more minutes until smooth and creamy. Finally, fold the whipped cream into the filling.
6. Fill and Garnish: When the cookies have cooled, scoop the filling into each cookie creating a mound. Garnish with a thin wedge of lime, lime zest, a small star of whipped cream, and a sprinkle of graham cracker crumbs.

Recipe Tips

• I can’t recommend any substitutions for this recipe, since it is a copycat recipe and each of the ingredients is chosen to make the cookies taste and feel a certain way.
• You will need 5-6 limes for this recipe. Zest 2 or 3 limes and save the zest for garnish before you juice the limes for the filling. You’ll need additional limes to cut into wedges. 
• If you want to add whipped cream to your cookies, it’s best to do this just before serving. Fresh whipped cream will melt after a bit of time in the fridge. You can also make a stabilized whipped cream or use premade whipped topping.
• You can prepare these cookies ahead of time. Make the shells and store them in an airtight container on the counter, and then make the filling, and store it in a zipper bag in the fridge. When you’re ready, snip off a corner of the bag and fill the cookies up.
• The 4-inch baking tins that I used can be purchased in a package of six. Since this recipe makes 18 cookies, you’ll want to bake in three batches or pick up a few packages of mini tart tins.
