In a medium bowl, mix the plain Greek yogurt with the honey until well combined.
Gently fold in the diced mango pieces, making sure they’re evenly distributed throughout the yogurt mixture.
Line a baking sheet with parchment paper. Spoon small dollops of the mango yogurt mixture onto the parchment paper, forming clusters. You can make them as big or as small as you like.
Place the baking sheet in the freezer and let the clusters freeze for at least 1 hour, or until they are firm.
In a microwave-safe bowl, combine the white chocolate chips and coconut oil. Microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth.
Once the yogurt clusters are frozen, remove them from the freezer. Dip each cluster into the melted white chocolate, using a fork to help coat them evenly. Then add coconut shreds to the top. Place them back on the parchment paper.
Return the clusters to the freezer for another 15 minutes, or until the chocolate is set.
Once the white chocolate is set, your clusters are ready to enjoy! Transfer them to an airtight container and keep them stored in the freezer for a refreshing treat anytime.
