Prepare the oven: Preheat the oven to 360°F. Lightly grease a 9-inch pie pan with butter or oil.
Mix dry ingredients: Sift the flour, cornstarch, salt, and baking soda into a bowl. Set aside.
1 teaspoon cornstarch, ½ teaspoon baking soda, ½ teaspoon salt, 1 ½ cups all-purpose flour
Cream the butter and sugars: Beat the butter and sugars on medium speed for 3 minutes until the texture is creamy and fluffy.
½ cup unsalted butter, ⅓ cup granulated sugar, ½ cup packed brown sugar
Add wet ingredients: Mix in the egg and vanilla until fully combined.
1 large egg, 1 teaspoon vanilla extract
Combine and mix: Gradually add the flour mixture to the wet ingredients and mix until just combined. Be careful not to overmix. Fold in the chocolate chips.
1 ½ cups chocolate chips
Assemble the pie: Press the batter into the prepared pie pan and top with ¼ cup of additional chocolate chips.
1 ½ cups chocolate chips
Bake the pie: Bake for 20-25 minutes until the top is golden brown but still soft in the center. After 15 minutes of baking, cover the pie with aluminum foil to prevent over-browning.
Cool and serve: Remove the pie from the oven and let it cool on a cooling rack. Serve warm or at room temperature with whipped cream and caramel sauce.
