This fudge is a proven winner! People will love it and want the recipe but DON'T give it to them - you won't want them to know how little effort you actually put into it:
1 can sweetened condensed milk (use the flavoured ones for a little "something" extra)
2 cups chocolate chips (any kind - milk, semi-sweet, even chocolate mint)
1/2 tsp vanilla (use rum or almond extract instead if you feel like it)
1 tsp. butter
dash salt
Put the milk and chips in a saucepan and melt over low heat until they can be combined smoothly together. Stir in the rest of the ingredients. Pour onto a buttered plate. Throw on a few festive sprinkles before it completely sets up. Cool at room temperature until it's firm enough to cut.
