You will love this Key Lime Cookie Recipe

My husband absolutely LOVES key lime pie! I have spent hours and years trying to bring Key Lime to the next level. Throughout all my attempts and versions, key lime pie remains at the top of his dessert list. There is just something about the combination of sweet and tart that is absolute perfection. 

So when Crumbl came out with a Key Lime Pie cookie, I KNEW that I had to figure out how to make a perfect copycat! And this my friends is it! 

A perfectly sweet graham cracker cookie topped with a deliciously tart cream cheese/key lime frosting, these cookies will knock your key lime loving socks off every time!

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

  1. 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.
  2. 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.
  3. 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. 
  4. Bake for 12-15 minutes until the cookies start to brown slightly. 
  5. 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.
  6. 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. 
  7. 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. 
  8. When your filling is finished and your cookies are completely cooled, scoop the filling into the center of each cookie and spread. 
  9. Cool the cookies in the fridge and top with whipped cream and a fresh lime slice right before serving.

How to store Key Lime Cookies

These cookies need to be stored in the the fridge. They do freeze well, if you want them to last longer! They will stay fresh in the fridge for up to one week and can be frozen for 2 months.

Key Lime Cookie FAQs

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.

How long do key lime pie cookies last?

If stored in the fridge, they will last for up to 5 days. You can freeze for up to 3 months, however.

    My husband says these are the best cookies he ever had. I made a batch for a fundraiser and got asked for the recipe. They are incredible! I love ALL the Crumbl copycat recipes I’ve made from your website, how easy they are with a batch of twelve, and never had an issue with things not turning out. I like that I don’t have to be stingy with frostings and fillings because there’s always plenty. And for anyone reading this, I always weigh my raw batch of dough then divide by 12 to get evenly sized cookies. Yum!!

    My 4 year old and I made these today and they were amazing. We followed your recipe exactly, but used a 1/4 cup of cookie dough for smaller cookies. They were still a great size. Thank you so much!!!

    To freeze these, do you bake and ice completely? Wanting to make ahead a couple days and not sure if I should freeze or if just refrigerated is okay.

    The first batch I made were flat. I followed the recipe. Could have been the weather. They were still yummy. I’ve made the chocolate chip and cosmic brownie and people have raved over them. They actually thought they came from crumble. Thanks for sharing.

    I bake something roe everyone’s birthday at work. I like to make their favorite dessert and will sometimes put my own twist on it. I made these for a co-workers birthday, she loves key lime pie, and they were a MAJOR hit! I measured out 1/4 cup of cookie dough to make smaller cookies and they were perfectly sized for an individual serving.

    Loved this recipe! It makes so many cookies and there’s lots of filling!

    If freezing the uncooked dough, how long will it last in the freezer? How long will the mixture last in the fridge?

    I made these with “flax eggs” as our kids are allergic to eggs, and the cookies turned out AMAZING. Thank you so much for an amazing recipe our whole family can enjoy!!
