How To Make
To a medium-sized saucepan over medium heat, bring the sugar, unsweetened chocolate, milk, butter, Crisco, and light corn syrup to a boil.
Prep the ice bath
Add ice to a large stainless steel or glass bowl that is big enough for the saucepan to fit. Add about 1 cup of water to the bowl then set aside.
Boil icing for 1 minute
Once the icing is at a rolling boil, let boil for 1 minute without stirring. Remove from heat and stir in the vanilla extract.
If desired, the vanilla extract can be swapped with almond extract. Before deciding on which extract to add, consider your dessert flavor. Almond extract pairs best with raspberry, peach, plum, butterscotch, chocolate, and maple flavors while vanilla extract complements cherry, orange, strawberry, cinnamon, hazelnut, and chocolate flavors.



Whisk icing in the ice bath
Immediately place the saucepan into the ice bath. Holding the handle of the saucepan, whisk the icing for about 1 minute or just until the icing starts to slightly thicken up. If the icing seems too runny, continue to whisk until it thickens.
Immediately pour onto the cake or dessert of choice. This icing will harden quickly so make sure to pour it while still runny.
