Everyone likes the way I make it:

1 can sweetened condensed milk
1 and 1/2 pkgs. white choc. chips
1/2 tsp. good vanilla
pinch of salt
You can add any other flavor, nuts, marshmallows, etal to this and it turnes out SOOOOO good!

Melt the chips in a double boiler until creamy, then remove from heat. Add the other ingredients and blend well. Spread the fudge in a pan whose bottom has been lined with waxed paper. Let cool overnight, cut and ENJOY!
