Hi Bold Bakers!

WHY YOU’LL LOVE THIS RECIPE: My easy Potato Donuts Recipe gives you the golden, crisp edges and soft and tender middles you crave, and the secret is mashed potatoes! You’d never guess this humble ingredient could make such a difference, but the mashed potatoes give these treats their perfect texture.

• Quick prep: It takes just 20 minutes to mix the dough, and then it rests in the fridge overnight.
• Super soft: Mashed potato adds moisture and tenderness, making these cake donuts incredibly soft and plush.
• Easy on the budget: My Potato Doughnuts cost about half as much as a dozen bakery donuts (and they taste better, if I say so myself!).
• No machine or yeast: Mix the batter up by hand with no kneading or proofing required. Aside from the frying, this is a great recipe for kids to help with!
• Easily customizable: Add your personal touch! Change up the spices in the topping, or dip them in glaze and add sprinkles.

When I worked as a pastry chef in a Michelin-starred restaurant, I made hundreds of donuts, so I know that frying is where you can really make or break the donut. My biggest tip for you is to pay close attention to the oil temperature: if the oil is too hot, the outsides will be browned before the insides are cooked, and if it’s too cold, the donuts could come out greasy. Do a quick test with a scrap of dough before you start frying the donuts—if it browns too quickly or too slowly, adjust the heat. And don’t toss that hot oil once you’re done! Once it’s completely cool, strain it through a sieve lined with a paper towel to remove any crumbs, then store it to reuse.

It’s no secret that I love all kinds of donuts, and I especially adore cake-style donuts, with their satisfying texture. Making donuts at home might seem tricky if you’ve never done it, but I’m here to tell you, homemade donuts are simple and so worth it! Warm golden-brown donuts are such an incredible treat, and you won’t believe how good they smell while cooking!

What are Potato Donuts?

My Potato Donut Recipe yields fried cake donuts with a mildly sweet flavor, a pleasant touch of earthy richness from the potato, and a soft, moist crumb. Frying the donuts makes them crisp on the outside and pillowy and tender inside. Potato Donuts descended from sweet German potato fritters called “fastnachts,” and a similar recipe made in a donut shape started appearing in the late 1800s. A potato donut shop called Spudnuts first opened in Utah in 1948, and today, home cooks and independent shops are rediscovering this uniquely tasty donut.

Key Ingredients and Substitutes

Potato Doughnut Dough

Eggs

• Eggs bind the batter into a smooth, even mixture and give the donuts structure.
• In addition, eggs contribute moisture and richness.
• Substitute: Instead of an egg, you can use a flax egg here.
  • Please take a look at my guide, 12 Best Egg Substitutes for Baking Recipes and How to Use Them, for more suggestions and information.

Granulated sugar

• Sugar sweetens the donuts.
• Additionally, sugar helps with the browning of the donuts through the Mallard Reaction and adds a subtle caramel note.
• Substitute: You can use the same amount of brown sugar, which will add a subtle molasses flavor to the homemade potato donuts.

Mashed potatoes

• Plain mashed potatoes give these homemade donuts a tender, soft, plush texture.
• Importantly, the potato’s starch locks in moisture, keeping the donuts fresher longer than regular donuts.
• In addition, you can also use homemade or prepared, plain mashed potatoes, or instant mashed potatoes made with whole milk and no additional seasonings.

Whole milk

• Whole milk contributes moisture to the donuts.
• Importantly, using whole milk here is essential, as it gives the donuts richness.
• Substitute: You can use an equal amount of plant-based milk, but note that the donuts may not be as rich.

Butter

• Butter gives the donuts flavor and a rich mouthfeel.
• Substitute: You can use the same amount of melted coconut oil instead, but note that it might give the donuts a slight coconut flavor.

Salt

• Salt brings out all of the flavors in the donuts and elevates the taste overall.

All-purpose flour

• Using both all-purpose flour and mashed potatoes ensures a stable structure so the donuts hold their shape.
• It’s important to note that without the flour, the potato donuts would fall apart.
• Substitute: You can use the same amount of a gluten-free baking mix, like my Easy Almond Flour Baking Mix or another gluten free flour instead of the all-purpose flour.
  • Note that donuts made with gluten-free baking mix may be more crumbly.

Baking powder

• Baking powder is a leavener that makes the donuts fluffy.

Nutmeg

• Nutmeg adds a note of pleasantly aromatic spice to this potato donut.
• Substitute: You can use an equal amount of cinnamon or cardamom (which will add a citrusy flavor) instead of the nutmeg.

Vegetable oil

• For deep-frying, use a vegetable oil with a neutral flavor that won’t overpower the donuts. It’s also essential that the oil has a high smoke point.
  • The smoke point is the temperature at which an oil visibly smokes and breaks down, resulting in a burnt taste.
• The best oils to use are vegetable oil, canola oil, sunflower oil, or safflower oil.
  • Do not use olive oil or flavored oils like sesame or walnut oils.

Cinnamon Sugar Topping

Cinnamon

• Cinnamon adds warm sweetness.
• Substitute: For a different flavor profile, you can use an equal amount of pumpkin pie spice.

Granulated sugar

• Granulated sugar adds sweetness and a pleasant crunch.

Salt

• Salt balances the sweetness in this donut recipe with potato.

How to Make Potato Donuts Recipe

To Make the Potato Donuts Dough

1. Combine wet ingredients and salt. In a large bowl, whisk together the eggs, sugar, warm mashed potatoes, milk, butter, and salt until smooth.

2. Finish the dough. In a medium bowl, combine the flour, baking powder, and nutmeg, then work this into the potato mixture until you have a very soft dough that holds together, but just barely.

3. Chill overnight. Wrap the dough in plastic wrap and refrigerate overnight, or up to two days.

Prepare the Cinnamon Sugar Topping

4. Mix topping ingredients. In a shallow bowl, mix together the sugar, cinnamon, and salt until combined. Set aside.

Shape the Doughnuts

5. Prepare to cut donuts. Sprinkle flour on a baking sheet and set it nearby.
6. Roll out dough. On a well-floured work surface, roll the dough to a ½-inch (12 mm) thickness.
7. Cut donuts. Cut out your doughnuts using a 3-inch (7 ½ cm) and a 1½ -inch (3 ⅘ cm) round cutter.

8. Place donuts on pan. Transfer the doughnuts to the floured baking sheet, then gather and roll the scraps until you have cut out all you can.

Fry the Potato Doughnuts

9. Prepare to fry. Place a wire rack on top of a rimmed baking sheet next to you by the stove. Keep the cinnamon sugar nearby as well.
10. Heat oil. Pour the oil into a wide, medium-sized, heavy-bottom pan and heat over medium heat until a cooking thermometer reads 325°F – 350°F.
11. Fry until golden brown. Using a spatula, carefully place 3 – 4 doughnuts in the oil and fry for 2 to 3 minutes on each side, , flipping around the three-minute mark, until they are golden brown all around.

12. Roll in topping. Let the doughnuts drain on the wire rack until just cool enough to handle, then roll in the cinnamon sugar while still warm. Return to the wire rack to finish cooling. Repeat with the remaining doughnuts.

Gemma’s Pro Chef Tips

• Don’t add too much flour. When mixing the dough, a minimal amount of flour is used to keep the doughnuts from becoming overly dense. The dough should just come together with the flour called for in the recipe, but if the dough is too loose to handle, you can knead in a touch more flour, one tablespoon at a time, until it holds its shape.
• Use plain homemade mashed potatoes. For best results, use homemade plain (without added spices, cheese, onion, garlic, or other flavorings) mashed potatoes. Prepared plain mashed potatoes or plain instant mashed potatoes also work.
• Chill dough overnight. The overnight chilling of the dough will allow the flour to evenly hydrate and make the dough easier to handle. You can leave to dough in the refrigerator for up to two days.
• Use enough oil. The potato in these doughnuts makes them a bit denser than regular doughnuts and they will sink a bit in the oil. The oil should be at least 2 inches (5 cm) deep, or the doughnuts may touch the bottom of the pot and burn.
• Use caution while frying. Use caution when frying and never walk away from oil heating on the stove. It will get very hot, and if it gets too hot, it can ignite. It’s always best to use a thermometer. And if you are a child, please get the help of a grown-up.
• Keep the temperature steady: Keep the temperature of the oil at 325°F (165°C). If you allow the oil to get too hot, the outside of the potato doughnuts will brown, but the insides will remain raw.

Make Ahead and Storage Instructions

• Make-ahead tips: You make this dough a day ahead and rest it for 24 hours (and up to two days) in the fridge before shaping and frying.
• How to store leftovers: These are best the day they are made, but leftovers can be stored in an airtight container at room temperature for one day.

FAQs

Can I use instant mashed potatoes in this recipe?

• Yes, you can use instant mashed potatoes in this recipe.
• Make 1 cup of mashed potatoes as directed. For the best flavor, make the potatoes with whole milk, and not with water. Additionally, please don’t add any additional seasoning or butter when making the instant mashed potatoes.
• Note that donuts made with instant mashed potatoes will differ from the donuts made from the original recipe.

How can I make these gluten-free?

• It’s easy to make these donuts gluten-free.
• In this recipe, in place of the all-purpose flour, use an equal amount of my Easy Almond Flour Baking Mix, another gluten-free flour, or a store-bought gluten free baking mix.

Is it possible to make this potato donut recipe without eggs?

• Yes, it’s possible to make this potato donut recipe without eggs.
• A good substitute in this recipe is a flaxseed egg. For each egg, mix one tablespoon of ground flaxseed plus three tablespoons of water, and set aside for 5 minutes before mixing with the other ingredients.
• My guide, 12 Best Egg Substitutes for Baking Recipes and How to Use Them, provides additional ideas.

What’s the difference between fried donuts and baked donuts?

• Fried donuts, like this Potato Donuts Recipe, are known for their crispy outside crust and a rich, soft interior.
• Baked donuts have a different texture that’s lighter and more like a sweet muffin.
