In a food processor, blend together dates, water, and ½ teaspoon cinnamon along with a pinch of salt. Set aside.
Mix the remaining cinnamon into ½ cup yogurt and set aside.
Cut each flatbread horizontally into 6 thin slices.
Alternate coating the top of each flatbread piece with yogurt or date mixture, so that you end up with 6 flatbread pieces topped with yogurt and 6 flatbread pieces topped with the date mixture.
Place one flatbread piece with date mixture on top of a flatbread slice coated with the yogurt mixture. Slowly roll the flatbread to create a cinnamon roll shape.
Repeat this process to create 6 ‘cinnamon rolls’
Place the rolls into a muffin tin. Drizzle the melted butter evenly over each roll.
Place in oven and bake for 10-12 minutes or until the flatbread has become slightly browned.
Remove from the oven and allow to cool for 1-2 minutes. Coat with the remaining Greek yogurt as frosting and serve warm.
