20 oz. (2 1/2 pkg. ) cream cheese
6 - 10 c. powdered sugar
2 tsp. vanilla extract
6 oz. white chocolate
1/4 c. heavy cream
In a large saucepan combine the white chocolate and cream over medium heat, stirring constantly until the chips are melted and the mixture is smooth. Remove from heat and let cool slightly.
Beat the cream cheese until smooth. Beat in the vanilla and then 2 cups of powdered sugar. Beat in 2 more cups of sugar and then the cooled white chocolate mix.
Continue beating in powdered sugar until the frosting is stiff enough to hold its shape.
This makes enough to fill and frost a 3-layer 9 inch cake.
