Ingredients

Graham Cracker Cookie

  • 1 box vanilla cake mix {15.25 ounces}
  • ¼ cup light brown sugar {packed}
  • 1 ¼ cup graham cracker crumbs
  • ½ cup butter {melted}
  • 2 eggs

Key Lime Cheesecake Frosting

  • 16 ounces cream cheese {softened}
  • 14 ounces sweetened condensed milk
  • ½ cup key lime juice {or lime juice}
  • ¼ cup powdered sugar

Topping

  • ¼ cup whipped topping

Instructions

  • Preheat the oven to 350°.

Graham Cracker Cookies

  • In a medium bowl combine the vanilla cake mix, brown sugar and graham cracker crumbs. Whisk to combine the dry ingredients.
  • Add the melted butter and eggs to the dry ingredients and mix using a hand held or stand mixer until you have a thick dough.
  • Use a ¼ measuring cup to measure out dough and form each dough mound into a large disc. Place 6 onto a silicone mat {or parchment} lined baking sheet. Bake for 9-11 minutes or until set. Remove from the oven and use the bottom of a drinking glass to make an indentation into each cookie. Allow the cookies to cool completely on the baking sheet. Continue until all of the dough is baked.

Key Lime Cheesecake Frosting

  • Once the cookies have cooled, combine the softened cream cheese and sweetened condensed milk in a medium bowl with a hand held mixer until smooth. Add key lime juice and powdered sugar, continue to mix until you have a creamy filling.
  • Add the filling to a piping bag or spoon the filling into the indentations of each cookie. Sprinkle the top of the filling with a few additional graham cracker crumbs.
  • To finish the cookies, add whipped topping to a piping bag, fitted with the star attachment {or a zipper bag} and pipe a bit of whipped topping in the middle of each cookie. Add a wedge of lime and serve.

Notes

  • Purchase graham cracker crumbs from the supermarket and save yourself time. They are in the same section as the pie filling and ready made pie crusts.
  • Instead of juicing key limes, use key lime juice from a jar.  It is available for purchase at most major grocery stores.
  • Add a teaspoon of regular lime zest to the frosting for a special touch.It gives the cookies a deeper lime flavor and looks gorgeous!
Store- The best way to store Crumbl Key Lime Pie Cookies is in the refrigerator. They should be in a single layer and will stay fresh for up to 4 days.
Freeze- You can freeze Key Lime Pie Cookies for up to 3 months. I would suggest freezing the cookies and then filling them with the key lime filling after defrosting for the freshest and best texture.
