Quick Fudge Icing or Candy

Combine sugar, cocoa, butter, milk, and light corn syrup in a medium saucepan over medium heat.

Stir constantly until the mixture reaches a full rolling boil, then continue cooking for 2 minutes without stirring.

Remove the pan from heat and allow the mixture to cool to room temperature, approximately 10 minutes.

Sift the confectioners' sugar into a large bowl to remove any lumps.

Pour the cooled fudge mixture into the confectioners' sugar and add the vanilla extract.

Beat the mixture with an electric mixer on medium speed for 3-5 minutes until it reaches a spreadable consistency and loses its glossiness.

Use the icing immediately as a topping for cakes or cookies, or pour into a greased 8-inch square pan to set as candy, cutting into squares once firm.
