Mock Whipped Cream

½ ounce (1½ tablespoons) corn flour
½ cup (4 ounces) milk
1½ ounce (3 tablespoons) butter
1 tablespoon sugar
Few drops vanilla extract
Mix corn flour with a bit of the milk to make a paste. Heat remainder of the milk in a small saucepan; when boiling, add the corn flour paste. Stir well, return to a boil, and cook 3 minutes, whisking constantly. Remove from heat and set aside. Cream butter and sugar; then, whisk in corn flour mixture gradually. Add vanilla extract and mix well.
