Key Lime Pie Lasagna Recipe Ingredients

How to Make This Key Lime Pie Lasagna Recipe

For the Crust

STEP ONE: Preheat the oven to 350°F. Generously spray a 9×13-inch glass baking dish with nonstick cooking spray. Set it aside.

STEP TWO: Using a small mixing bowl, stir together the graham cracker crumbs, melted butter, and granulated sugar until well combined.

STEP THREE: Evenly press the crust into the bottom of the prepared baking dish. Bake for 6 minutes, then allow the crust to completely cool before adding the second layer.

For the Cheesecake Layer

STEP ONE: Using a medium bowl and a handheld mixer on medium-high speed, beat the cream cheese for 30 seconds to 1 minute, until smooth.

STEP TWO: Add the vanilla and beat just until combined.

STEP THREE: Add the powdered sugar and mix on low speed until well incorporated.

STEP FOUR: Fold in the whipped topping.

STEP FIVE: Evenly spread the cheesecake over the completely cooled crust. Cover tightly and chill in the refrigerator.

For the Key Lime Layer

STEP ONE: Using a 2 to 3-quart heavy-bottomed saucepan on medium-high heat, whisk together the granulated sugar and cornstarch.

STEP TWO: Whisk in the lime juice, melted butter, and slightly beaten egg yolks.

STEP THREE: Continuously whisk the ingredients until they begin to simmer and thicken.

STEP FOUR: Remove the saucepan from the heat. Cover the saucepan and chill the key lime custard in the refrigerator for 2 hours, or until completely chilled all the way through.

STEP FIVE: Once the key lime mixture is completely chilled, fold in the whipped topping and 2 to 3 drops of green food color.

STEP SIX: Evenly spread over the cheesecake layer.

STEP SEVEN: Evenly spread the second 8-ounce tub of thawed whipped topping over the key lime layer. Cover tightly with plastic wrap and chill in the refrigerator for 6 hours to overnight.

STEP EIGHT: Just before serving, slice eighteen 1½-inch x 3-inch long servings. Evenly sprinkle the graham cracker crumbs and lime zest.
