That should read 2- 3 oz packages for a total of 6 oz.
I have made this using the low fat cream cheese and non fat whipped topping and it is still wonderful. No one even notices the difference. Have also used it as filling in a really rich chocolate cake and then iced it with chocolate icing. Always take those to church suppers as I don't want it sitting around here calling my name for any length of time
