Doughnuts made with mashed potato? Absolutely. Potato doughnuts have been around for over 150 years; in fact, the original Krispy Kremes were made with potato, whose starch adds moisture to help keep doughnuts tender. Give these old-fashioned cake doughnuts a try, and find out what doughnut fans back in the day were raving about!

Instructions

Prevent your screen from going dark as you follow along.

  1. Sift together the flour, baking soda, salt, baking powder, and nutmeg. Set aside.

  2. In a separate bowl, cream together the shortening and sugar. Add the eggs and mashed potatoes to the shortening mix.

  3. Measure out the milk. Add the flour mixture and milk alternately to the creamed mixture, beginning and ending with the flour mixture.

  4. The resulting dough will be quite soft, more like a drop-biscuit dough instead of a "rollable" dough. The dough can be covered and refrigerated overnight, if desired.

  5. Turn the dough out onto a very well floured surface and knead a few times to make it stiff enough to roll with a rolling pin. Roll the dough using a well-floured rolling pin until it's about 1/2" thick. Dip a doughnut cutter in flour (each time you cut), and cut out the doughnuts. Save the holes; or re-roll them with leftover dough. Try to handle the dough as little as possible; the less you work the dough, the more tender the doughnuts will be.

  6. Heat the fat to 365°F. Test the temperature with a thermometer; or with a slice of bread, as follows: lower half a slice of bread into the hot fat. If it takes 1 minute for the bottom side to brown nicely, the fat is at the best temperature for frying doughnuts.

  7. Fry doughnuts about 2 minutes on each side or until golden brown. Drain on brown paper bags or paper towels. Check one of the fried donuts after it is cooled to be sure the center is cooked through.

  8. While still warm, shake doughnuts in cinnamon sugar or plain granulated sugar.

Tips from our Bakers

  • Older recipes are often very large — too large for today's bakers. For instance, the original recipe that inspired this one started with 5 cups of flour. This variation was cut in half for today's bakers.
  • How do you add dry and wet ingredients "alternately?" In this case, you want to add the flour mixture and liquid in 5 additions, as follows: add about 1/3 of the flour mixture and stir until mixed. Then add half the liquid, stir until mixed, the next 1/3 of the flour, and so on until the ingredients form a dough. This is called the cake method of mixing and helps create a light, fluffy baked (or fried) food.
  • This doughnut dough can be held or refrigerated overnight. Equally good doughnuts will result from making the dough and frying the same day, OR making the dough one day and frying the next.
