Start by preheating your oven to 350°F. Place your pie crust into a 9-inch pie dish and crimp the edges gently, then set that aside for later.
Whisk the brown sugar and melted (and cooled) butter together in a large bowl.
Add in your eggs and vanilla then whisk again until smooth.
Add your flour and salt to the mixture and mix it until well combined.
Add your chocolate chips and stir them in.
Pour the cookie batter into your prepared pie crust and smooth it out carefully with a rubber spatula on top. Sprinkle more chocolate chips on top if desired.
Bake in the preheated oven for 45-50 minutes or until a toothpick pushed into the center comes out clean. Let cool on a wire cooling rack until ready to serve.
Serve warm or at room temperature.
Notes
Serve warm with vanilla ice cream for the best experience!
