Blend everything but the cookies and whipped topping in a blender. Taste and adjust as you'd like, adding more sweetener or more cacao powder if needed.
Pour into ice an ice cube tray or mold and freeze until solid.
When ready to make, add the cubes to a blender and blend, scraping down the sides often, until a super thick shake forms. You may need to add a little drizzle of milk to get things moving along.
Add some melted chocolate drizzle to a glass and pour in the frap. Top with coconut whipped cream and crushed cookies. Enjoy!
Notes
You can also add crushed cookies or chocolate chips in the frap!
