Place the pumpkin puree, Greek yogurt and the remaining ingredients, except the chocolate chips and nuts, in a large mixing bowl. Using a hand electric mixer or a whisk, mix together until you reach a smooth consistency.
Give it a taste and adjust flavor to your liking (add a bit of molasses or brown sugar to sweeten some more, for example. Or adjust the spices if you want more cinnamon or nutmeg.) Mix again to combine.
Transfer the pumpkin-yogurt mixture to small (3-ounce) serving goblets or small mason jars. Cover and refrigerate for 30 minutes or overnight.
When ready to serve, top each with a drizzle of molasses, chocolate chips and chopped hazelnuts or walnuts. Enjoy!
