Step 1: In a large bowl, combine the finely crushed vanilla wafers, finely chopped pecans, and 1 cup of powdered sugar. Mix well to ensure all ingredients are evenly distributed.
Step 2: In a separate small microwave-safe bowl, melt the unsalted butter. Once melted, stir in the light corn syrup and vanilla extract.
Step 3: Pour the wet ingredients into the dry ingredients. Mix thoroughly with a spoon or your hands until a cohesive, dough-like mixture forms. The mixture should be sticky but hold together.
Step 4: If the mixture is too soft to roll, cover the bowl and refrigerate for 15-20 minutes to firm it up slightly.
Step 5: Place extra powdered sugar in a shallow dish for coating. Roll the mixture into 1-inch balls. Immediately roll each ball in the powdered sugar, ensuring it's fully coated.
Step 6: Arrange the coated pecan pie balls on a plate or baking sheet. Refrigerate for at least 2 hours to allow them to firm up completely before serving.
