Crush vanilla wafers into crumbs; you'll need 1.5 cups worth. In a medium bowl, add the vanilla crumbs and melted butter. Mix together and then firmly press into the bottom and up the sides of a 9-inch pie plate.
Bake the crust for 10-12 minutes or until golden brown. Allow the pie crust to fully cool.
In a bowl, whisk together the sweetened condensed milk, egg yolks, orange zest, orange juice, and lemon juice until smooth. Pour the pie mixture into the cooled crust.
Bake for 15-20 minutes or until the center has set. Allow the pie to cool to room temperature; then refrigerate for a minimum of 3 hours.
Top pie with whipped cream and garnish with orange zest and slices, if desired. Slice and enjoy!
Notes
For the best flavor, use freshly squeezed orange and lemon juice, along with freshly grated orange zest. Fresh citrus adds brightness and enhances the creamsicle flavor of the pie.
Pre-baking the vanilla wafer crust ensures that it stays crisp and holds its shape when slicing the pie.
To achieve the perfect creamy texture, refrigerate the pie for a minimum of 3 hours, or preferably overnight, before serving. This allows the filling to set completely and enhances the flavors.
