Whole Wheat 30 Minute Mini Cinnamon Buns (healthy)

Preheat the oven to 375 degrees. Spray a mini muffin tin with cooking spray. To make the dough place the flour, brown sugar, baking powder and salt in a medium size mixing bowl. Stir in the buttermilk until a dough ball forms. Turn out onto a heavily floured surface (if there is not enough flour the dough will stick to the counter when you are trying to roll the dough into a log). Roll the dough into an a rectangle about 1/4th inch thick. If the dough sticks to the rolling pin add more a sprinkle more of flour, but try and add as little flour as you can. The more flour you add the dryer the dough will be. Spread the melted coconut oil all over the dough and then sprinkle with the brown sugar and cinnamon. I like to use my hands to spread the sugar around the dough, again I ender up using probably a litte less than a 1/4 a cup. Roll into a log and cut into 15 or 16 equal buns (If some of the dough rips while rolling, just pinch it back together. It is no big deal, dont stress!). Place the buns into the prepared muffin tins. Bake for 12-14 minutes or until the buns are lightly browned. Allow to cool for about 5 minutes and spoon icing over top each bun. To make the icing mix the powder sugar, milk and vanilla in a small bowl until smooth. Serve with the cinnamon buns.
