Mix whey, Neufchâtel cheese, and stevia until combined.
Roll into 8 balls, and place on a parchment-lined tray. Set in refrigerator. (If they are sticky and the balls don't come smooth, freeze them for about 5-10 minutes and then roll again to smooth.)
Melt the chocolate in a double boiler, and transfer to a smaller bowl. Add stevia and mix well.
Remove truffles from the refrigerator, and use a fork to dip each in the melted chocolate. Set back on parchment, and place back in the refrigerator for at least 10 minutes. If you have additional chocolate, give them a second coating.
Once chocolate coating is set, mix drizzle ingredients (if desired), and drizzle onto truffles.
Enjoy! Store in the refrigerator.
