4½ Tbsp sugar
1 Tbsp plus 1 tsp baking powder
1¼ tsp baking soda
2½ cups buttermilk or sour milk
1 cup butter, melted
Filling:
5 Tbsp butter, melted
5 Tbsp brown sugar
Zest of 2 oranges
Glaze:
1½ cups powdered sugar
2 tsp orange zest
4- 8 Tbsp orange juice
Preheat oven to 425 degrees F. Mix together all the dry dough ingredients. Then add the buttermilk and butter, dough may be wet. Add flour as needed to achieve a soft dough. Pat out the dough into a large rectangle about ½" thick. Pour the 6 Tbsp melted butter over the entire dough and use a pastry brush to get it around the edges. Mix together the brown sugar and orange zest in a small bowl. Sprinkle the mixture over the dough. Roll up the dough from the long side. Slice into 12 rolls and place in a greased 9 by 13 baking dish. Bake for about 20 minutes until golden brown around the edges. Add together glaze and pour over the rolls while they are still hot.
