Preheat the oven to 350 F.
Line a baking pan with parchment paper
In a large mixing bowl, sift together four, baking powder and salt
In a separate bowl, combine flour mix and yogurt and mix well, using your hands knead the dough until fully combined and shape into a ball
Lightly flour a kitchen surface, using a rolling pin roll out dough into a thin (around ½ an inch) rectangular shape
Combine sugar, melted coconut oil and cinnamon until a paste forms and evenly spread over the top of the dough
Slowly roll dough starting from one of the shorter rectangular sides until the dough is in a cylinder shape
Place a piece of string under the cylinder and cross the ends to slowly cut the dough into 5 even cinnamon buns
Arrange the rolls in the prepared pan
Bake for approximately 35-40 minutes or until the edges begin to turn golden brown
While the rolls are baking, combine the icing ingredients
Remove the buns from the oven and allow them to cool. Once cool, spread icing over the top of the rolls and enjoy!
