The present invention provides a package assembly that incorporates a foamable topping under pressure and provides the consumer with a fresh, foamed topping when the package is opened. In one version, the topping material is carried under pressure on top of the liquid contents of the package, and foams when the package is opened. In other versions the topping is carried within the cap or cover of the package, and is selectively dispensed by the consumer after the package has been opened.
