Creating these amazing potato donuts is straightforward if you follow these simple steps:

1. Prepare the Potatoes: Begin by peeling and boiling the potatoes until fork-tender. Drain and mash until completely smooth.
2. Combine Wet Ingredients: In a large mixing bowl, combine the mashed potatoes, eggs, milk, and vanilla extract. Mix until well blended.
3. Mix Dry Ingredients: In another bowl, whisk together the flour, sugar, baking powder, salt, nutmeg, and cinnamon.
4. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients. Mix until just combined; do not overmix.
5. Roll Out the Dough: On a floured surface, roll the dough to about ½ inch thick. Use a donut cutter to punch out donut shapes.
6. Heat the Oil: In a large pot or deep fryer, heat the oil to 350°F (175°C).
7. Fry the Donuts: Carefully place a few donuts into the hot oil, cooking until they are golden brown on both sides (approximately 2-3 minutes each side).
8. Drain the Oil: Once cooked, remove the donuts with a slotted spoon and place them on paper towels to drain.
9. Cool: Allow the donuts to cool for about 10 minutes before glazing or serving.

These steps will guide you through the process of creating potato donuts that will tantalize your taste buds with every bite.
