Preheat oven to 350 degrees F. Line a large baking sheet with parchment paper.
In a large mixing bowl, combine cake mix, eggs and melted butter. Beat until well mixed. Batter should be sticky and thick. Roll into 1-inch balls and place on prepared baking sheet.
Bake for 6-8 minutes. Let cool on baking sheet 5 minutes before removing to a wire rack to cool completely.

In a medium bowl, whisk corn syrup, butter and vanilla. Stir in pecans, chocolate chips and coconut flakes. Spread frosting over tops of cooled cookies.
For drizzle:
In a small bowl, melt chocolate chips. Stir until smooth. Drizzle over tops of frosted cookies. Place in refrigerator to set completely.
