Cinnamon Sugar Sourdough Doughnuts

4.2 from 5 reviews

Sourdough starter gives these doughnuts an extra depth of flavor and balances with the baking powder for a texture that is somewhere between cake doughnuts and yeast ones.


  • ½ cup sourdough (you can make your own using this technique)
  • 2 Tablespoons oil
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • 1 egg
  • 2 cups flour (I usually need 1/31/2 cup more to make the dough managable )
  • 1/2 cup sugar
  • ¼ teaspoon cinnamon
  • ½ teaspoon salt
  • 1/3 cup buttermilk


  1. Prepare a pot or deep fryer for frying.
  2. Line a tray with paper towels and set aside, you will use this for draining doughnuts.
  3. Heat oil to 360 degrees.
  4. Sift the flour, baking powder and baking soda
  5. In a bowl mix the sourdough starter, oil, buttermilk and egg.
  6. Add the sugar, cinnamon and salt to the dry ingredients and then add them to the wet ingredients.
  7. Bring dough together gently with you hands. Sprinkle some flour onto a work surface and turn dough on to it. Knead it gently about 3 times to help bring the dough together.
  8. Roll out to a thickness of 2 centimeters and cut with a doughnut cutter or if you are like me, you can use a round cutter (I used my 1/2 and 1/4 cups) and a bottle cap
  9. Fry until golden brown. Test the first one for doneness by breaking it in two and checking if the middle is doughy.
  10. Drain on paper town. Toss with vanilla sugar or cinnamon sugar to coat or top with your favorite topping
