Place a piece of parchment paper on a baking sheet.

Using a cookie dough scoop, scoop out and roll cookie dough into about 12 balls. Place balls onto prepared baking sheet and place in refrigerator to chill for about 30 minutes (or up to 4 hours).

While the cookie dough balls are chilling, place one color of candy melts in a large microwave-safe bowl and microwave on 50% power for 45 seconds. Stir and continue heating at 50% power in increments of 15 seconds until candy melts are completed melted. Be careful not to overheat. Add 1 tablespoon of shortening and stir until combined.

Using a fork or toothpick, dip cookie dough balls one at a time in the melted wafer candy melts. Tap fork gently on bowl to remove excess. Place dipped balls back onto baking sheet to dry.

Follow step three to melt the second color of candy melts. Place melted wafers into a pastry or Ziploc bag. Cut off a tiny piece of the bag to create a small hole. Drizzle over cookie dough balls and add sprinkles immediately, if desired.
