- 1/2 cup butter, softened
- 6 tablespoons shortening
- 1 cup white sugar
- 2 teaspoons vanilla extract
- 1 tablespoon cornstarch
- 1/2 cup warm milk
- In a large bowl, cream butter, shortening, sugar and vanilla together. Stir cornstarch into milk and add to butter mixture. Beat at low speed until well blended. Beat another 5 to 7 minutes until icing is creamy.
