Step 1: Line an 8×8 inch square baking pan with parchment paper, leaving an overhang on the sides for easy removal of the fang fudge bites.
Step 2: In a medium heat-proof bowl, combine the dark chocolate chips and the sweetened condensed milk.
Step 3: Place the bowl over a pot of simmering water (double boiler method) and stir constantly until the chocolate is completely melted and the mixture is smooth.
Step 4: Remove from heat and stir in the sea salt and vanilla extract until fully incorporated.
Step 5: Pour the mixture into the prepared pan and spread evenly with a spatula. Refrigerate for at least 2 hours or until very firm.
Step 6: Lift the fudge out of the pan using the parchment paper and cut into 24 small squares to prepare the base for your fang fudge bites.
Step 7: Melt the white chocolate wafers in the microwave in 20-second intervals until smooth. Transfer to a piping bag with a small tip.
Step 8: Pipe two small downward-pointing triangles (fangs) onto each fudge square to complete your fang fudge bites.
Step 9: Allow the white chocolate to set completely before serving. Store the fang fudge bites in an airtight container in the refrigerator.
