Line a baking sheet with parchment paper and set aside.
Using a spoon, mix applesauce, coconut sugar, maple syrup and vanilla extract together in a mixing bowl.
In a separate bowl, stir together oat flour, cocoa powder and salt.
Add the dry ingredient mixture to the wet ingredient mixture, and stir until combined.
Fold in 1/3 cup chocolate chips.
Use a small cookie scoop (I recommend a #50 or #60 disher) to scoop out dough and form into balls with your hands. Place dough balls onto parchment-lined baking sheet (makes approximately 10-12 dough balls).
Place in freezer for 10 minutes.
While cookie dough bites are in the freezer, make the chocolate drizzle by combining 1 tablespoon chocolate chips and coconut oil in a small, microwave-safe bowl. Microwave in 15 second intervals, stirring between each one, until chocolate is smooth. Set aside until ready to use.
Dip a small spoon into the melted chocolate and using a back and forth motion, drizzle a line of chocolate across the top of each cookie dough bite. Repeat going in the other direction.
Place cookie dough bites in the freezer for 10 more minutes.
Keep cookie dough bites refrigerated in an airtight container for up to five days. They can also be kept in an airtight container in the freezer for up to 2 weeks.
