Biscuit Dough
2 cups Baking Mix
4 tablespoons cold butter, cut into pieces
1 cup buttermilk
Filling
2 tablespoons butter, softened
2 tablespoons brown sugar
2 tablespoons granulated sugar
2 teaspoons cinnamon
Icing
3/4 cup powdered sugar
1 1/2 tablespoons whole milk or half-n-half
Preheat oven to 425 degrees. Lightly grease a 9-inch pie pan.
To make the biscuit dough, cut the butter into the Baking Mix until it resembles coarse crumbs. Make a well in the center and add the buttermilk all at once. Stir until a soft dough forms. Turn the dough out onto a lightly floured surface and knead 5 or 6 times. Roll or pat the dough into a 9 x 12-inch rectangle.
Spread the softened butter over the dough. Sprinkle evenly with the brown sugar, granulated sugar and cinnamon. Starting with one of the short sides, roll the dough into a log pinching the seam to seal. Cut the log into 8 equal pieces and place them, cut side down, into the prepared pan.
Bake for 20-25 minutes, or until the biscuits are golden brown. Remove from the oven and let cool for 5 minutes while preparing the icing.
In a small bowl, combine the powdered sugar and milk stirring until smooth. It should be pourable but not too runny. Drizzle icing evenly over the biscuits spreading as necessary.
Serve warm.
