Beat cream cheese until smooth. Add powdered sugar and cocoa powder, then beat on low until incorporated. Turn the speed up and beat until smooth.
Slowly add the cream and whip on slow until it is well incorporated and smooth.
Slowly pour in the powdered instant pudding mix. Increase the speed and whip for 2 to 3 minutes until it is thick. If it gets too thick, add additional cream until it reaches the consistency you want.
