In this recipe, I used a 7 1/4" springform pan from Pampered Chef, but you can use any size you have. Just keep in mind that if you are using a larger size, you may need to increase the cookie crust ingredients and your pie will not be as tall as mine. You can always adjust the ingredients by adding another block of cream cheese, 2 Tbsp of key lime juice, 2-3 Tbsp of powdered sugar, and whip up 1 ½ cups of heavy whipping cream for a taller pie OR you can add a layer of sweetened whipped cream on the top! You can also use a regular pie pan or a deep dish pie pan for this recipe.
