Ingredients
For the Potato Donuts:
- 2 cups (about 400g) plain mashed potatoes, cooled (ensure no lumps, and no milk or butter added yet)
- 1/4 cup (50g) granulated sugar
- 1 large egg, lightly beaten
- 2 tablespoons (28g) unsalted butter, melted
- 2-3 tablespoons (30-45ml) milk (any kind)
- 1/4 cup (30g) cornstarch
- 2 teaspoons baking powder
- 1/2 teaspoon ground cinnamon (optional)
- 1/4 teaspoon salt
- 4-6 cups (approx. 1-1.5 liters) neutral oil for frying (such as vegetable, canola, or peanut oil)
For the Simple Vanilla Glaze:
- 1 cup (120g) powdered sugar
- 2-3 tablespoons (30-45ml) milk (any kind)
- 1/2 teaspoon vanilla extract
Ingredient Notes
- Mashed Potatoes: The key to these donuts! Use unseasoned, plain mashed potatoes (potatoes simply boiled and mashed, without butter, milk, or salt added) that have cooled completely. Russet or Yukon Gold potatoes work best for their starchy texture.
- Cornstarch: This acts as a binder and provides structure in place of traditional flour, helping to achieve that desired fluffy texture. Do not skip it, as it’s crucial for the dough’s consistency.
- Milk: Use any milk you prefer – dairy or non-dairy. Adjust the quantity slightly based on the consistency of your mashed potatoes; you want a soft, manageable dough.
- Frying Oil: Choose a neutral-flavored oil with a high smoke point to prevent burning and impart no unwanted flavors to your donuts.
Equipment You’ll Need
- Large mixing bowls
- Whisk
- Rubber spatula or wooden spoon
- Rolling pin
- Donut cutter or two round cookie cutters (one larger, one smaller)
- Large, heavy-bottomed pot or Dutch oven for frying
- Slotted spoon or spider strainer
- Wire rack set over a baking sheet
- Thermometer for oil temperature (highly recommended)
How to Make Fluffy Potato Donuts
- Prepare the Dough: In a large bowl, combine the cooled mashed potatoes, granulated sugar, beaten egg, melted butter, and 2 tablespoons of milk. Mix until well combined.
- Combine Dry Ingredients: In a separate medium bowl, whisk together the cornstarch, baking powder, cinnamon (if using), and salt.
- Form the Dough: Add the dry ingredient mixture to the wet potato mixture. Mix with a spatula or your hands until a soft, slightly sticky dough forms. If the dough is too stiff, add the remaining tablespoon of milk, one teaspoon at a time, until it’s just workable. Be careful not to overmix.
- Chill the Dough: Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes. This helps firm up the dough, making it easier to handle.
- Roll and Cut: Lightly flour a clean surface with a small amount of cornstarch. Turn the chilled dough out onto the surface and gently roll it to about 1/2-inch (1.25 cm) thickness. Use a donut cutter or two round cutters (one 3-inch/7.5 cm and one 1-inch/2.5 cm) to cut out donut shapes. Gather and re-roll scraps once to cut out more donuts.
- Heat the Oil: In a large, heavy-bottomed pot or Dutch oven, pour enough neutral oil to reach about 2-3 inches (5-7.5 cm) deep. Heat the oil over medium-high heat until it reaches approximately 350-375°F (175-190°C). An oil thermometer is highly recommended for accuracy.
- Fry the Donuts: Carefully lower 2-3 donuts (don’t overcrowd the pot) into the hot oil. Fry for about 1-2 minutes per side, or until golden brown and cooked through. The internal temperature should reach about 200°F (93°C).
- Drain and Cool: Using a slotted spoon or spider strainer, carefully remove the fried donuts from the oil and transfer them to a wire rack placed over a baking sheet to drain excess oil and cool slightly. Repeat with the remaining dough.
- Prepare the Glaze: While the donuts are cooling (they should still be warm), whisk together the powdered sugar, 2 tablespoons of milk, and vanilla extract in a shallow bowl until smooth. If the glaze is too thick, add more milk, a teaspoon at a time, until it reaches your desired consistency.
- Glaze the Donuts: Dip each warm donut into the glaze, turning to coat both sides. Place them back on the wire rack for the glaze to set. Serve immediately for the best flavor and texture.
Pro Tips for the Best Results
- Perfect Mashed Potatoes: Ensure your mashed potatoes are smooth and lump-free. For the best texture, use a potato ricer or mash thoroughly. Allow them to cool completely before mixing, as warm potatoes can make the dough too sticky.
- Don’t Overmix: Mix the dough just until combined. Overmixing can develop any gluten-like properties in the cornstarch or make the texture tough.
- Chill the Dough: This step is crucial! Chilling the dough makes it much easier to handle, roll, and cut without sticking.
- Maintain Oil Temperature: Use an oil thermometer to keep the frying oil between 350-375°F (175-190°C). Too cool, and the donuts will be greasy; too hot, and they’ll burn outside before cooking inside.
- Don’t Overcrowd the Pot: Fry only a few donuts at a time to maintain the oil temperature and ensure even cooking.
- Glaze While Warm: Dipping the donuts in glaze while they are still warm (but not hot) allows the glaze to adhere beautifully and absorb slightly, creating a delicious coating.
Common Mistakes to Avoid
- Using Lumpy Mashed Potatoes: Lumps will lead to an inconsistent dough and unappealing donut texture.
- Not Chilling the Dough: Trying to roll out warm, sticky dough will be frustrating and messy. Give it time to firm up in the fridge.
- Incorrect Oil Temperature: This is the most common cause of greasy or burnt donuts. Always use a thermometer.
- Overcrowding the Fryer: Adding too many donuts at once will drop the oil temperature significantly, resulting in soggy donuts.
- Over-glazing Hot Donuts: Dipping extremely hot donuts in glaze can cause the glaze to melt and slide off rather than set nicely. Allow them to cool slightly first.
Variations & Substitutions
- Spice It Up: Add a pinch of nutmeg, cardamom, or pumpkin pie spice to the dough for an autumnal twist.
- Different Glazes: Experiment with a chocolate glaze (melted chocolate with a touch of milk), a lemon glaze (lemon juice instead of milk in the vanilla glaze), or a maple glaze.
- Toppings: Sprinkle with chopped nuts, shredded coconut, rainbow sprinkles, or a dusting of cinnamon sugar immediately after glazing.
- Potato Types: While russets are ideal, sweet potato puree can also be used for a slightly sweeter, earthier donut with a beautiful orange hue. Adjust sugar content accordingly.
- Mini Donuts: Use a smaller donut cutter to make bite-sized mini donuts, perfect for parties or sampling.
Serving Suggestions
These Fluffy Potato Donuts are best served warm, shortly after glazing. They make a fantastic breakfast treat alongside your morning coffee or tea. For a dessert option, serve them with a scoop of vanilla ice cream or a dollop of whipped cream. They’re also a unique and delightful addition to any brunch spread or a cozy afternoon snack.
Storage & Reheating
Potato donuts are best enjoyed fresh on the day they are made. The texture will be at its peak—soft and fluffy. If you have leftovers, store them in an airtight container at room temperature for up to 1-2 days. The texture may become slightly denser over time. To refresh, you can warm them briefly in a microwave for 10-15 seconds, or in a toaster oven at a low temperature (around 250°F / 120°C) for a few minutes until just warm. Avoid freezing glazed donuts, as the glaze can become watery upon thawing.
FAQ
Q: Can I make these donuts ahead of time?
A: While the donuts are best fresh, you can prepare the dough and chill it in the refrigerator for up to 24 hours. This allows you to fry and glaze them closer to serving time.
Q: Are these potato donuts gluten-free?
A: Yes, since this recipe uses cornstarch instead of traditional wheat flour, these potato donuts are naturally gluten-free.
Q: What kind of potatoes should I use?
A: Starchy potatoes like Russet or Yukon Gold are ideal for mashed potatoes because they yield a fluffy, less watery mash, which is perfect for this dough.
Q: My donuts are greasy. What went wrong?
A: Greasy donuts are usually a sign that your oil wasn’t hot enough. The donuts absorbed too much oil instead of quickly cooking and forming a crust. Ensure your oil is between 350-375°F (175-190°C) before frying.
Q: Can I bake these instead of frying?
A: This recipe is specifically developed for frying, which gives them their classic soft interior and crispy exterior. Baking may result in a denser, cake-like texture rather than a light, fluffy donut. We recommend sticking to frying for the best results.
Q: Can I use instant mashed potatoes?
A: For the best flavor and texture, freshly made mashed potatoes are recommended. Instant mashed potatoes often have additives and a different consistency that may not work as well in this recipe.
Q: How do I know when the donuts are cooked through?
A: They should be golden brown on both sides. If you’re concerned, you can check the internal temperature with an instant-read thermometer, which should be around 200°F (93°C). Alternatively, cut one open to check for doneness.
