LIST:
1 cup sugar
1 cup dry powdered milk
1/2 cup water
1 Tbsp butter

Howto:
Put sugar & powdered milk in a blender (I LOVE using my Ninja for this.)
Put water & butter in a microwaveable dish & let it come to a boil in your microwave; about 45-60 seconds.  Keep an eye on it.
Add water/butter mixture to mixer & blend until combined.  Scrape sides if you need to & blend again.
