Add yogurt, vanilla and cashew butter to a bowl. Mix together until fully combined. Fold in pomegranate seeds.
Spoon out mixture onto a sheet pan* lined with parchment paper (a plate or other flat surface also works) - forming 5-6 clusters. Freeze for 1-3 hours - until completely frozen through and solid. I have noticed that dairy yogurt takes longer to freeze than non dairy.
Melt together chocolate and coconut oil. I melted mine for 3 30 second intervals in the microwave.
Dunk each cluster in chocolate. Sprinkle over flaky salt if using. Freeze again for 10-15 minutes, until set.
Notes
This makes 5-6 yogurt clusters.*I used an ice cream scoop and filled it about ¾ of the way.
