In a mixing bowl, combine the butter and brown sugar. Using a hand mixer or whisk, beat them together until the mixture is light and fluffy. This should take about 2-3 minutes.
Pour in the heavy cream, vanilla extract, and salt. Mix until everything is well combined.
Gradually add the flour to the wet mixture, mixing until just combined. Be careful not to overmix. Fold in the mini chocolate chips for that extra chocolatey goodness.
Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes. Chilling helps the truffles hold their shape.
Once the dough is chilled, use a cookie scoop or your hands to form small balls, about 1 inch in diameter. Place them on a baking sheet lined with parchment paper.
In a microwave-safe bowl, melt the Ghirardelli Dark Melting Wafers in 30-second intervals, stirring in between until smooth. Be cautious not to burn the chocolate.
Dip each cookie dough ball into the melted chocolate, ensuring they are fully covered. Use a fork to lift them out, letting any excess chocolate drip off. Return them to the baking sheet.
If desired, sprinkle crushed Heath bars or colorful sprinkles on top of the chocolate-coated truffles before they set.
Refrigerate the truffles for an additional 30 minutes, allowing the chocolate to harden.
