My dad makes one similar to this one, without the bourbon, but it sounds like a nice addition:
Chocolate Chip Bourbon Pecan Pie
Courtesy of Michele's Pies in Nowalk, Conn.
1 10" piecrust
3 large eggs, room temperature
¾ cup sugar
1 ¼ cups dark corn syrup
½ tablespoon pure vanilla extract
1 tablespoons bourbon
3 tablespoons unsalted butter, melted and kept warm
1 ½ cup chopped pecans
¾ cups semi-sweet chocolate chips
Preheat oven to 350
Place the eggs, sugar, corn syrup, vanilla and Bourbon in a bowl and mix. Scrape the sides and bottom of the bowl at least two times while mixing. Add the warm butter. Mix well. Combine the pecans and chocolate chips and sprinkle them on the bottom of the pie shell. Pour the filling over the nuts and chips.
Place the pie on the baking sheet on the bottom shelf of the 350 degree oven and bake it for 30 minutes. The edges of the filling will rise, but the middle will still be a little bouncy. However, the pie will continue to bake after it is removed from the oven. To set up and have it firm enough to slice, give the pie 2 to 3 hours of cooling at room temperature, or a half hour of cooling at room temperature and an hour in the refrigerator.
