Add kiwi, yogurt and nut butter to a bowl. Mix together until fully combined.
Spoon out mixture onto a sheet pan* lined with parchment paper (a plate or other flat surface also works). Freeze for 1-2 hours, until firm.
Melt together chocolate and coconut oil. I melted mine for 3 30 second intervals in the microwave, stirring after each interval.
Dunk each cluster in chocolate. Freeze again for 10-15 minutes, until set.
Top with flaky salt if using, serve and enjoy. These can be stored in the fridge or freezer. I like to store mine in the freezer because I don't like biting into frozen things.
