For the Dough:
2 3/4 cup plain flour, plus extra for dusting the counter
2 tablespoons suger
1 1/4 teaspoon baking powder
1/2 teaspoon baking soda
3/4 teaspoon salt
1 1/4 cup buttermilk
6 tablespoons melted butter
For the filling:
2 tablespoons melted butter
2 tablespoons sugar
1 tablespoon cinnamon
For the glaze:
2 tablespoons water
3/4 to 1 cup powdered sugar
Preheat oven to 425 degrees F.
In a bowl, mix together the dry ingredients for the dough (flour, sugar, baking powder, baking soda, and salt).
Stir in the butter and buttermilk.
At this point, the dough will be sticky, so just spoon it on top of a heavily floured surface, and add a bit more flour to the top.
With floured hands, gently knead the flour into the dough (adding more flour if necessary) until the dough is manageable and is fairly smooth.
With a rolling pin, roll the dough out into a rectangle/square of approximately 1/2 inch thick.
Spread the surface of the dough with 2 tablespoons melted butter, then sprinkle on the cinnamon and sugar.
Roll the dough from the longer side, and cut the dough to about 2 inches thick.
Place the rolls in a lightly greased pan, and bake at 425 degrees for about 20 minutes, or until the edges have turned golden brown.
To prepare the glaze, mix the water and powdered sugar, and pour onto the rolls while they are still hot.
