In a large bowl, mix together the crushed vanilla wafer crumbs, ground pecans, confectioners sugar, and baking cocoa until well combined.

In a separate small bowl, whisk together the dark rum, honey, and water until fully blended.

Stir the rum mixture into the dry crumb mixture thoroughly, ensuring all parts are evenly combined to form a cohesive, sticky dough.

Roll the mixture into approximately 1-inch balls using your hands to shape each one tightly.

Roll each ball in additional powdered sugar or sprinkles to coat them evenly for added flavor and decorative effect.

Place the coated rum balls on a tray and chill in the refrigerator for at least 30 minutes, or until firm and set, ready to serve.
