I made these doughnut holes and rubbed them in sugar and cinnamon while they were still hot (that is the only way you can get the sugar to stick on them). They were ‘cakey’, soft and delicious.
I got a recipe from http://www.justataste.com/ but I was not really satisfied with it and I had to make some changes to it, I increased the quantity of flour from 2 to 3 cups.
For the doughnut holes:
5 cups vegetable oil, for frying
1 cup milk
1 large egg
3 cups all-purpose flour
2 Tablespoons sugar
4 1/2 teaspoons baking powder
1/2 teaspoon salt
1/4 cup (1/2 stick) unsalted butter, melted
Make the doughnut holes:
Add the vegetable oil to a large, heavy-bottomed pot. Attach the deep-fry thermometer to the pot and begin heating the oil over medium heat to 350ºF. Line a tray with paper towels.
In a small bowl, whisk together the milk and the egg.
In a separate medium bowl, whisk together the flour, sugar, baking powder and salt. Stir the milk-egg mixture into the dry ingredients, then stir in the melted butter, mixing until a soft dough forms.
Once the oil has reached 350ºF, use a small ice cream scoop to drop about 1 tablespoon scoops of dough into the oil, careful not to overcrowd the pan. (See Kelly’s Notes.) Fry the doughnut holes, flipping them in the oil, for about 2 minutes or until they’re golden brown. Using a slotted spoon, transfer the doughnut holes to the paper towel-lined tray/baking sheet.
Rub the doughnut holes into the sugar and cinnamon mixture and you are all done!
