Wash hands with soap and water for 20 seconds. Preheat oven to 350 o F. Line a baking sheet with parchment paper.
Place the coconut oil and chocolate chips in a microwaveable bowl. Microwave on high for 40 seconds, takeout and stir. Microwave additional 15 seconds until melted. Now add in flour, sugar, salt and vanilla, mix until a dough is formed.
Break an inch of the dough. Now on a floured surface roll the dough so it becomes a rope shape.
Turn the rope into a U shape. Then crossover the two ends so that they overlap each other, twice.
Take the two ends and flip them over to the bottom making a pretzel shape. Then press the ends gently. Place the cookie on the prepared baking sheet. Repeat from step 3 until all the dough is used.
Now pour the milk in a bowl and brush the cookies with it.
Sprinkle with the rock sugar. Bake for 20 minutes. Take out and let them cool for a few minutes, enjoy!
