Melt the chocolate. Add the chocolate chips and heavy whipping cream to a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until fully melted and smooth. Set aside to cool for 5 minutes.
Beat the cream cheese. In a medium mixing bowl, beat the softened cream cheese with a hand mixer or spatula until completely smooth with no lumps.
Combine. Pour the cooled chocolate mixture into the cream cheese along with the powdered sweetener, vanilla extract, and sea salt. Mix until fully combined and silky smooth.
Chill the mixture. Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or until the mixture is firm enough to scoop and roll.
Roll the truffles. Once chilled, use a small cookie scoop or tablespoon to portion out the mixture. Roll each portion quickly between your palms to form a ball.
Coat. Immediately roll each truffle in your coating of choice — cocoa powder, chopped nuts, or shredded coconut — pressing gently to adhere.
Set and store. Place the finished truffles on a parchment-lined baking sheet and refrigerate for another 15–20 minutes to firm up before serving. Store in an airtight container in the fridge for up to 2 weeks.
