Key Lime Pie Cookie Ingredients

For The Cookies

Butter-You will want to make sure your butter is softened so that it can cream together with the sugar.
Granulated Sugar
Brown Sugar-Using both types of sugar creates the perfect chewy texture and will help keep your cookies moist.
Eggs
Vanilla–A big heaping helping of vanilla gives these cookies a great kick of flavor!
Flour-Plain old AP flour.
Graham Cracker Crumbs-These are going to give your cookies the perfect graham cracker crust flavor.
Baking Soda
Baking Powder
Salt-Just a pinch really balances out the sweetness and brings the flavors together.

For The Frosting

Cream Cheese- This recipe uses blocks of cream cheese. Technically you could use the tubs as long as it still equals 16 ounces.
Sweetened Condensed Milk
Lime Juice-My favorite brand is Nellie & Joe’s. The flavor is AMAZING! It can be found on the juice isle of most grocery stores. You can use fresh though if you prefer.
Powdered Sugar

For Garnish

Whipped Cream- A dollop of whipped cream right on top really adds so much to the overall flavor of the cookie.
Lime Slices- This is totally optional but adding a small lime slice makes the final product so adorable!

How to make this Key Lime Cookie Recipe

Start by preheating the oven to 350 degrees.In a stand mixer or a bowl with a hand mixer, cream together the butter and sugar. Add the eggs and vanilla and mix again until light and slightly fluffy.
Add the flour, graham cracker crumbs, baking powder, baking soda and salt and mix again until the dough just comes together. The dough will be a very dry dough, you’ll have to pack it together for it to stick together.
Portion the dough into 12 1/2 cup pieces of dough. Roll each portion into a ball and place 6 balls onto a cookie sheet. Press down on each dough ball and flatten them just a bit.
Bake for 12-15 minutes until the cookies start to brown slightly.
Right after you take the cookies out of the oven, use the bottom of a cup, gently press down on the center of the cookie creating an indentation for the pie filling.Allow the cookies to cool completely.
While the cookies are cooling, make the filling by beating the cream cheese until smooth. Add the sweetened condensed milk and mix again until thoroughly combined.
Finally add the powdered sugar and lime juice. Remember, you can always add more powdered sugar or more lime juice to get your desired tanginess.
When your filling is finished and your cookies are completely cooled, scoop the filling into the center of each cookie and spread.
Cool the cookies in the fridge and top with whipped cream and a fresh lime slice right before serving.

Can I use lime juice instead of Key lime?

Absolutely! Key limes are very small and you’ll need a lot of them to be able to get significant juice out of them. Feel free to use either key lime juice or lime juice.

What is the difference between lime and key lime?

The main difference is the size and color. Key limes are smaller and darker in color. Key limes do have a slightly sweeter taste, but most of the time it isn’t super noticeable.
