Ingredients
  

Crust

  • cups finely crushed graham crackers
  • ½ cup salted sweet cream butter, melted
  • 3 tablespoons granulated sugar

Cream Cheese Layer

  • 10 ounces cream cheese, softened
  • cups powdered sugar
  • cups whipped topping, thawed
  • teaspoons vanilla extract

Key Lime Pie Layer

  • cups granulated sugar
  • ¾ cup fresh key lime juice
  • ½ cup salted sweet cream butter, melted
  • tablespoons cornstarch
  • 5 egg yolks, slightly beaten
  • cups whipped topping, thawed
  • 3 to 4 drops green food coloring

Topping

  • 2 cups whipped topping thawed
  • 2 tablespoons finely crushed graham cracker crumbs, optional garnish
  • 1 tablespoon freshly lime zest, optional garnish

Instructions
 

Crust

  • Preheat the oven to 350°F. Generously spray a 9x13-inch glass baking dish with nonstick cooking spray. Set it aside.
  • Using a small mixing bowl, stir together the graham cracker crumbs, melted butter and granulated sugar until well combined.
  • Evenly press the crust into the bottom of the prepared baking dish. Bake for 6 minutes, then allow the crust to completely cool.

Cheesecake Layer

  • Using a medium-sized mixing bowl and a handheld mixer on medium-high speed, beat the cream for 30 seconds to 1 minutes, until smooth.
  • Add the vanilla and beat just until combined.
  • Add the powdered sugar and mix on low speed until well incorporated.
  • Fold in the whipped topping.
  • Evenly spread the cheesecake over the completely cooled crust. Cover tightly and chill in the refrigerator.

Key Lime Layer

  • Using a 2 to 3-quart heavy-bottomed saucepan at medium-high heat, whisk together the granulated sugar and cornstarch.
  • Whisk in the lime juice, melted butter and slightly beaten egg yolks.
  • Continuously whisk the ingredients until they begin to simmer and thicken.
  • Remove the saucepan from the heat. Cover the saucepan and chill in the refrigerator for 2 hours, or until completely chilled all the way through.
  • Once the key lime mixture is completely chilled, fold in the whipped topping and 2 to 3 drops of green food color.
  • Evenly spread over the cheesecake layer.
  • Evenly spread the second 8-ounce tub of thawed whipped topping over the key lime layer. Cover tightly and chill in the refrigerator for 6 hours to overnight.
  • Just before serving, slice eighteen 1½-inch x 3-inch long servings. Evenly sprinkle the graham cracker crumbs and lime zest.

Notes

  • If you need to crush your graham crackers, you can toss them in the food processor or crush them in a Ziploc with a rolling pin until they are fine crumbs.
  • Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your crust as the suggested baking time approaches.
  • Make sure the cream cheese is at room temperature so that you don’t end up with lumps in your creamy mixture.
  • If you want a deeper shade of green, increase the green food color drops to 3 to 5.
