I just made a batch of this frosting for a pan of pumpkin chocolate chip bars. It is SO delicious! I had to fight the urge to consume most of it before I even put it on the cake.
1 (8 ounce) package cream cheese, softened
1/4 cup butter, softened
2 1/2 cups confectioners' sugar
1 1/2 teaspoons vanilla extract
Milk, as needed, to achieve proper frosting consistency
In a medium bowl, cream together the cream cheese and butter until creamy. Mix in the vanilla, then gradually stir in the confectioners' sugar. Add milk, as needed, until frosting is of a suitable consistency for spreading. Store in the refrigerator after use. Makes enough to frost an 11 x 13-inch cake.
