Begin by spraying the bottom and sides of a 9-inch springform pan with nonstick cooking spray. This will prevent your pie from sticking and make it easier to remove once set.
In a medium bowl, stir together the finely crushed Oreo cookies and the melted butter. Use a fork to combine them well until the mixture resembles wet sand.
Press the cookie mixture firmly into the bottom and about 1 inch up the sides of the pan. This crust provides the delicious first layer of Turtle Pie. Chill it in the refrigerator while you prepare the filling.
In a medium bowl, combine the chewy caramels and 4 tablespoons of heavy whipping cream. Heat this mixture in the microwave on high for 2 to 3 minutes, stirring every 30 seconds. You want it to be smooth and creamy.
Once smooth, stir in the kosher salt and the chopped pecans. Pour this caramel mixture evenly into the chilled crust and spread it out with a spatula.
In a large bowl, place the chocolate chips and the remaining heavy whipping cream. Heat this mixture in the microwave for about 1 minute and 15 seconds. Stir until the chocolate has melted completely and the mixture is smooth.
Spread the chocolate mixture evenly over the caramel layer, making sure it’s well covered. The contrasting layers create an impressive visual appeal.
Sprinkle coarse sea salt generously on top for that perfect finish. It adds a delightful hint of saltiness that enhances the overall flavor.
Now, chill the pie in the refrigerator for about 2 hours to set. Patience is key as this allows all the flavors to meld beautifully.
When ready to serve, let the pie sit on the counter for about 10 minutes. If using a springform pan, gently remove the sides while the pie is still cold for the best result.
