Line a square 8 inch baking pan with parchment paper and set aside.

Over low heat, in a medium sized pot, add the chocolate chips, condensed milk and salt, stir with a wooden spoon until chips are melted. Remove from heat and add the vanillas. (If you don't have vanilla paste, just double up on the vanilla extract) Pour into the parchment lined baking pan and spread evenly. Refrigerate for 4 hours until firm.
