Melt the semi-sweet chocolate in a microwave safe dish at 30 second intervals, stirring between each, until melted.
Transfer the melted chocolate to a large mixing bowl. Stir in the powdered sugar, corn syrup, extract, rum and salt until smooth.
Fold in the vanilla cookie crumbs until it is evenly mixed. Cover and chill for 1-2 hours.
Using a 1tablespoon cookie scoop, roll into balls. Immediately while still tacky, roll the balls in your desired toppings. You’ll need about 1 cup total- so ½ cup of two or ¼ cup of 4 toppings.
Transfer them to an airtight container and keep chilled until ready to serve.
When serving, take them out of the fridge for about 15 minutes to let them soften a tad.
