What each ingredient does

Marshmallows
Melt into a sweet, glossy, sticky base that sets soft as the icing cools.
Extract (vanilla or other)
Adds aroma and flavour to the icing.

The step that matters

Do not beat after removing from heat. The icing thickens as it cools. Beating it further pulls air in and lets the sugar set, so it turns stiff and hard to spread.
