Pro tip
Add the vanilla wafers to a food processor. Pulse a few times to break them up, and then process until it forms fine crumbs.
Add the cocoa powder, salt, sweetened condensed milk, rum, and vanilla.
Process until well-combined.
Roll the mixture into slightly heaping 1-tablespoon-sized balls. Roll in sprinkles or any coatings you like!
