Before you start this recipe, make sure you have BOILING water. I don't mean warm water or hot water, I mean boiling hot water. The heat helps the sugar dissolve, so it's a must.

Place the dry milk and sugar in the blender and pulse twice. Quickly add melted butter, BOILING water, vanilla, and salt. Blend on medium high for 3-4 minutes.

Pour out into jars and store in a cool, dry place in an airtight jar.
