In a saucepan, mix sugar, cocoa, cornstarch and salt together. Mix well.

On medium heat, stir in milk and continue to stir until mixture thickens. It will eventually come to a boil, just keep stirring until pudding thickens.

Once pudding has thickened, add butter and vanilla. Turn off burner and stir for another minute.

Place in a dish and use saran wrap to seal tight. Place in refrigerator for minimum of 1 hour before serving.

For whipped topping, add all ingredients listed under whipped topping section into a mixing bowl.

Using a powered mixer, mix on high speed until the mixture is firm. You will know when you are done, trust me. If you are doing this by hand with a wired whisk, I highly commend and bow down to you because it will take a while. Great workout if using the by hand-method.

Arrange pudding in a dish and top with the whipped cream. Sprinkle with a hint of unsweetened cocoa and enjoy :)
