Whip butter with sugars and vanilla until light and fluffy, about 1 minute. Mix in all dry ingredients including chocolate chips until completely combined. Dough should be moist and slightly crumbly. Roll into desired sizes and shapes. Place on baking sheet lined with waxed paper. Store in refrigerator until ready to coat in chocolate. (If you want to keep them plain, refrigerate them 30 minutes or so until they are hard and can retain their shape and transfer them to a ziploc bag.)Melt chocolate wafers in microwave or over double boiler. Drop dough balls one by one into melted chocolate. Drizzle chocolate over dough to coat and using a spoon, remove chocolate covered balls, attempting to remove any excess chocolate in the process. Place on waxed paper and chill in the refrigerator until firm. Store in an airtight container on the counter or in the fridge for up to 5 days.
