1/2 c. boiling water
3 tbsp. butter
1/2 c. sugar
1 1/3 c. dry powdered milk

Pour the boiling water into blender. Add other ingredients and blend briefly. Scrape sides and blend 30 seconds. Pour out and let stand until thick and cool. This makes the equivalent of 14 ounce can of sweetened condensed milk and will keep for a long time if refrigerated.
