In a medium bowl, mix together the Greek yogurt, shredded coconut, honey or maple syrup, vanilla extract, and salt until well combined. The mixture should be thick and sticky.
Take a small amount of the mixture and shape it into a doughnut by rolling it into a ball and then making a hole in the center with your finger or the end of a spoon. Alternatively, use a doughnut mold if you have one.
Place the shaped doughnuts onto a baking sheet lined with parchment paper. Repeat until all the mixture is used.
Place the baking sheet in the freezer for about 20-30 minutes, or until the doughnuts are firm and easy to handle.
In a microwave-safe bowl, combine the chocolate chips and coconut oil. Microwave in 20-second intervals, stirring between each, until the chocolate is fully melted and smooth.
Remove the doughnuts from the freezer. Dip each doughnut into the melted chocolate, covering them completely. Allow any excess chocolate to drip off, and then place the doughnuts back on the parchment-lined baking sheet.
Place the dipped doughnuts back in the freezer or fridge for about 10-15 minutes, or until the chocolate is set and firm.
