Step 1

Preheat oven to 325°F. Fit piecrust into a 9-inch metal pie plate; crimp edges. Sprinkle pecans and chocolate chips evenly over piecrust.

Step 2

Whisk together corn syrup, granulated sugar, and brown sugar in a saucepan. Bring to a boil over medium-high; boil, whisking occasionally, until sugars are dissolved, about 5 minutes.

Step 3

Whisk together eggs, butter, flour, bourbon, vanilla, and salt in a heatproof bowl. Slowly pour 1/3 cup of the hot corn syrup mixture into egg mixture, whisking constantly until fully incorporated. Whisk in remaining hot corn syrup mixture until smooth. Pour filling over pecan mixture in piecrust.

Step 4

Bake in preheated oven until pie edges are set and begin to puff up, but pie center is still slightly jiggly, 45 to 50 minutes. Transfer to a wire rack; let cool completely to room temperature, about 2 hours. Slice and garnish with whipped cream and chocolate shavings.
