Sift flour, 1 cup sugar, 3 tablespoons cocoa, soda, and salt in 8- or 9-inch square pan. Make separate holes and put in oil, vinegar and 1 teaspoon vanilla. Pour water over all and beat or stir with fork until chocolate has mixed in (no white spots). Bake at 350° for about 30 minutes.

For the Fudge Frosting: Combine 1/2 cup cocoa, butter, 3/4 cup sugar, 1/2 teaspoon vanilla and sweet milk. Boil 1 minute. Cool. Beat tiny bit (until it starts to thicken) and pour on cake.
