Cook condensed milk, chocolate chips, and salt in a medium saucepan over medium-low, stirring constantly, until chocolate is melted and mixture is glossy and thick, 5 to 6 minutes. Remove from heat, and quickly stir in vanilla until combined.

Pour chocolate mixture into prepared pan; smooth top using a small offset spatula. Refrigerate uncovered until firm, at least 2 hours or up to 12 hours.

Remove from pan using parchment paper overhang as handles. Cut into 64 (about 1-inch) squares.
