Place chocolate chips and heavy whipping cream into a heavy-based saucepan on low heat. Stir frequently to melt the chips.
Line a loaf pan with parchment paper and pour the melted mixture into the pan. Place in the fridge for 2 hours to firm up.
To make the truffles, scoop up some of the chilled chocolate mixture and roll into balls (you can dust your hands with some cocoa powder if required). Alternatively you could press into a 1-inch dome mold. Freeze for 10 minutes.
Roll the truffles into the confetti sprinkles and place a heart-shaped sprinkle in the center.
