Fudge is not a twentieth-century invention, but fast fudge is. This recipe, an adaptation of the famous uncooked fudge developed by Philadelphia Brand Cream Cheese, became popular shortly after World War II, is as foolproof as it is fast. And it never turns gritty.

Philly Fudge

1 (6-ounce) package semisweet chocolate chips
2 (3-ounce) packages cream cheese, at room temperature
2 tablespoons milk or cream

5. Press mixture into pan, cover with plastic wrap and chill overnight or until firm. Cut into 1 1/4-inch squares.
