01 - In a large mixing bowl, combine the vanilla wafer crumbs, chopped pecans, powdered sugar, and cocoa powder. Stir until evenly distributed.
02 - In a separate small bowl, whisk together the bourbon, light corn syrup, and vanilla extract until well blended.
03 - Pour the wet mixture into the dry ingredients and stir thoroughly until a sticky, cohesive dough forms and no dry pockets remain.
04 - Using your hands, roll tablespoon-sized portions of the dough into 1-inch balls, pressing firmly so they hold together.
05 - Roll each ball in powdered sugar, coating generously on all sides. Gently shake off any excess.
06 - Arrange the coated balls on a parchment-lined baking tray and refrigerate for at least 2 hours to allow the flavors to meld and the texture to firm up before serving.
