In a small saucepan over medium heat, gently heat the heavy cream until it simmers but does not boil.

Remove from heat and stir in the dark chocolate chips until melted and smooth.

Add vanilla extract and a pinch of salt, stirring to combine.

Transfer to a fondue pot or heatproof bowl; keep warm while preparing dippers.

Serve with fruits, marshmallows, pretzels, or cake chunks for dipping.
