Preheat your oven to 350°F (175°C).

Lightly grease a 9-inch pie dish.

In a large mixing bowl, melt the butter and combine with brown and granulated sugars using an electric mixer on medium speed for about 2 minutes.

Add eggs one at a time, whisking well after each addition, and stir in vanilla extract.

In a medium bowl, whisk together flour, baking soda, and salt.

Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined.

Gently fold in the semi-sweet chocolate chips and any optional ingredients.

Spoon the cookie dough mixture into the greased pie dish and smooth the top.

Bake for 35 to 45 minutes until the edges are golden brown and the center is set but slightly soft.

Cool in the pie dish for 15 to 20 minutes before serving.
