Sweetened Condensed Milk

In a medium bowl, pour boiling water over butter, sugar and vanilla. Whisk until butter is melted and ingredients blend into a syrup.

Gradually add dry non-fat milk, blending with a handmixer (if you’ve got a whisk attachment, this works better). Blend really well.

Pour into a container and refrigerate overnight. Can be stored in the refrigerator up to 1 week.

Notes:
Milk will thicken when refrigerated and lumps of non-fat milk will dissolve into the syrup. Stir when needed. Don’t worry about froth on top—that’s normal after settling.

It’s better to make this a day before use.
