Step 1

Lightly mist a 9x9-inch pan with non-stick spray, and line it with parchment.

Step 2

Place the chocolate, condensed milk, and salt in a large bowl over very low heat.

Step 3

Stir the mixture continuously, until all the chocolate has melted and the mixture is very thick and shiny (about 5 minutes; please view the video to see what the mixture should look like.)

Step 4

Remove from the heat and stir in the vanilla extract.

Step 5

Transfer the fudge to the prepared pan, smoothing it into an even layer.

Step 6

Allow it to cool and set (about 1 hour), before cutting into 25 squares.
