Preheat your oven to 350°F (175°C). Grease your 9-inch pie dish lightly with non-stick spray or butter to prevent sticking.
In a mixing bowl, combine 1 cup of melted unsalted butter, 1 large egg, 1 cup of packed light brown sugar, and 1 teaspoon of vanilla extract. Whisk until combined. Gradually add in 1 ½ cups of all-purpose flour and ½ teaspoon of salt, mixing until a dough forms.
Press the dough evenly into the bottom and up the sides of the prepared pie dish. Make sure to create an even layer. Bake the crust in the preheated oven for about 10-12 minutes, or until it’s lightly golden. Remove from the oven and allow to cool slightly.
While the crust is cooling, mix together 10 ounces of sweetened condensed milk and 4 to 5 ounces of salted caramel sauce in a bowl until well combined. Stir in the 1 cup of sweetened shredded coconut, ensuring it’s evenly coated.
Pour the coconut and caramel filling over the cooled crust, spreading it out evenly. Sprinkle 1 cup of semi-sweet chocolate chips on top of the filling.
Return the pie to the oven and bake for an additional 15-20 minutes, or until the filling is set and the top is golden. Remove from the oven and let it cool completely.
Once the pie has cooled, melt ½ cup of semi-sweet chocolate chips in the microwave or using a double boiler. Drizzle the melted chocolate over the top of the pie for that beautiful finishing touch.
Slice into the pie and serve it as is, or with a scoop of vanilla ice cream on the side. Enjoy the delightful layers of flavor and texture in this Samoas Cookie Pie!
