To make your coffee milkshake, you will need a blender. Into the blender, add the instant coffee powder and milk, or cold brew coffee. Also, add cocoa powder if desired. Finally, add your scooped ice cream to the blender.

Secure the lid, then blend until the mixture is combined.

Take your serving glass and swirl it with chocolate syrup. Then pour in the blended coffee shake, and top with whipped cream and shaved chocolate if desired. Serve the coffee shake right away and enjoy your delicious beverage.
