In a medium saucepan over low heat, combine the semi-sweet chocolate chips and heavy cream. Stir continuously until the chocolate is completely melted and the mixture is smooth.
Remove from heat and stir in the vanilla extract and salt until well combined.
Allow the mixture to cool to room temperature, then cover and refrigerate for about 2 hours or until firm enough to handle.
Once the mixture is firm, use a small cookie scoop or your hands to form small balls (about 1 inch in diameter).
Roll each truffle in the red, white, and blue sprinkles to coat. If desired, you can also roll some in cocoa powder for a different flavor.
Place the finished truffles on a parchment-lined baking sheet and refrigerate for another 30 minutes to set.
Serve chilled or at room temperature.
