1 Cup Sugar
1/2 Cup light corn syrup
2 Tablespoons shortening
4 teaspoons cocoa
2 Tablespoons evaporated milk
1/2 teaspoon vanilla

In a bowl, combine sugar, shortening and cocoa. Mix well, and pour into a saucepan. Bring to a boil, and then simmer until temperature reaches 275 degrees (you will need a candy thermometer). Allow to cool for about ten minutes; add the evaporated milk and vanilla. Use an electric mixer to beat until very thick. Scrape candy onto a lightly greased cookie sheet and allow to cool. When cool, mold pieces into desired size and shape.
