Preheat your oven to 350°F (175°C).

Place the 9-inch pie crust into a standard pie plate, crimping or shaping the edges as desired. Set aside.

In a medium mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth and glossy.

Add the egg and vanilla extract, mixing until fully incorporated.

Sprinkle in the baking soda and salt, stirring to evenly distribute.

Gradually fold in the all-purpose flour, mixing just until no dry streaks remain. Do not overmix.

Stir in 1½ cups chocolate chips, reserving a small handful for topping.

Spread the cookie dough evenly into the prepared pie crust, smoothing the top with a spatula.

Sprinkle the reserved chocolate chips evenly over the surface.

Bake for 35–45 minutes, until the edges are set and golden while the center remains slightly soft.

Remove from the oven and allow the pie to cool for at least 20–30 minutes before slicing to set properly.
