Line the bottom and sides of a 9 x 9-inch baking pan with two crisscrossing pieces of aluminum foil, leaving an overhang on each side.
Combine the sugar, evaporated milk, butter, salt, and marshmallow cream in a heavy medium-sized saucepan over medium heat. Stirring constantly, bring the mixture to a boil and cook for 5 minutes.
Remove the saucepan from the heat and add the white chocolate chips, stirring until melted. (You may need to return the pan to low heat to melt the chips completely.) Add the bourbon and vanilla. Stir in the pecans.
Pour the mixture into the prepared pan and allow it to cool to room temperature, about 1 hour. Transfer the pan to the refrigerator and chill for 1 hour.
Using the ends of the foil as handles, lift the fudge out of the pan. Cut the fudge into 1-inch pieces.
