Sift the dry ingredients together flour, (baking powder, baking soda, spices, and salt) Add the brown sugar. Whisk together buttermilk, butter, and egg in a separate bowl, and add to dry ingredients. Donít over-work the dough that form. Heat oil in a deep saucepan or table top fryer. Make sure that the oil is clean (donít use oil thatís already been used for any other foods) Heat to 400. Use a small ice cream scoop to portion out small rounded doughnuts. Donít overload the pot. You should have enough room to turn each doughnut without touching another. Turn them occasionally, until golden brown, puffy and cooked thoroughly. Each should take 1-2 minutes. Remove the doughnuts as they become done and let blot on paper towels. Allow to cool for a couple minutes before rolling in cinnamon sugar to coat.
