These Copycat Crumbl Key Lime Pie Cookies taste just like a slice of pie, but in cookie form. They are so easy to make and even better than the real deal!

Key lime pie is a classic dessert. But why wait until you can get your hands on that first slice when you can make cookies better yet a copycat version of Crumbl Cookies.
We’ve recently got a Crumbl Cookies in my small town and had to run over there the day they were open to give them a try. Came home with a variety pack of cookies for the whole family to try and were hooked with each first bite. The key lime pie cookies were my absolute favorite so you know I had to brainstorm how to make a copycat version of them.
It took me several tries but I think I nailed it with this copycat recipe. These cookies are perfect for when you want something sweet and tart, or if you just want to impress your friends with an absolute dream of a cookie. Give this recipe a try and let me know what you think!
Recipe Tips
- Use real butter, not margarine or shortening.
- If you don’t have or can’t find key lime juice, you can substitute for lime juice. They taste will be a bit different and not as tart.
- Don’t have graham cracker crust? Can use regular graham crackers, just make sure they are finely crushed. A food processor works good in doing so.
- Store leftovers in the fridge in an airtight container for up to four days. To freeze: put in an airtight container and store in freezer for up to one month. Allow to thaw overnight in the fridge before consuming.

THIS recipe has 4 cups flour and 3 cups of Graham cracker crumbs I’m a baker it cannot possibly be right that it only makes 16 cookies they would have to be the size of a pie is it a misprint I was thinking of making this but that is really throwing me off

Crumbl cookies are pretty big and thick so that is right and not a typo. You could make them smaller to get more cookies if needed.

When scooping the cookies, how much are you scooping into one cookie? Are you using a measuring cup or a cookie scoop?
Alison
About a 1/2 cup size.
