In your mixing bowl place the heavy cream, vanilla extract, and sugar and stir to combine. Cover and chill the bowl and wire whisk in the refrigerator for at least 30 minutes, then beat the mixture just until stiff peaks form. (You can add some melted chocolate if you want chocolate flavor)
If you use powder whipped topping mix, then place 3/4 cup cold milk, 1 tsp vanilla essence with 2 packet powder in your mixing bowl. Then beat the mixture just until stiff peaks form (5 min).
