Scoop the ice cream into the Ninja Creami pint. Use a spoon to create a hole down the center of the ice cream. Pour the milk into the hole, along with the instant coffee and hot cocoa powder.
Place the pint into the Ninja Creami basket, cover, and secure in the Ninja Creami according to manufacturer directions.
Press "milkshake" and the Ninja Creami will process the ingredients for a couple of minutes.
Once the processing stops completely, remove the basket and pour the contents evenly divided into two large glasses.
Optional: Top with whipped cream, chocolate sprinkles, and chocolate-covered espresso beans.
