Preheat the oven to 350°F and generously grease a 9 inch pie dish, making sure the sides are well coated.
Whisk together melted butter, brown sugar, and granulated sugar until smooth, then add eggs one at a time and stir in the vanilla.
In a separate bowl, whisk flour, baking soda, and salt until evenly combined.
Gradually stir the dry ingredients into the wet mixture just until no dry flour remains.
Fold in the chocolate chips and any optional add ins gently.
Spread the dough evenly into the prepared pie dish and smooth the top.
Bake for 35 to 45 minutes until the edges are golden and the center is slightly soft, covering loosely with foil if browning too fast.
Cool for 15 to 20 minutes before slicing and serving.
