Preheat your oven to 350ºF. Place the unwrapped prepared pie crust on a baking tray + set aside.
In a small sauce pot, melt the butter + 2 oz. chocolate over low heat. Stir until just melted + remove from the heat. Add in the sugar + brown sugar. Stir until combine + they start to melt. Let cool for 5 minutes.
Whisk in each egg, one at a time, until fully incorporated. Mix in the vanilla extract.
Using a rubber spatula or wooden spoon, fold in the flour + salt until full incorporated. Mix in the chocolate chips.
Pour the batter into the prepared pie crust. Bake for 35-40 minutes or until the center is set. Remove from the oven and let cool.
Serve with ice cream, whipped cream or powder sugar - OR add them all! Enjoy!
