1915-Style Potato Donuts Recipe: Old-Fashioned Crispy Bites With Secret Flavor

This 1915-style potato donut recipe brings back the golden age of crispy, old-fashioned donuts that disappear faster than they hit the plate. The secret lies in a simple batter—mashed potatoes and flour—that creates a texture unlike modern donuts.

I first tried this recipe at a historic cookbook fair, where the aroma of freshly fried donuts transported me straight to a 1915 kitchen. The key to authenticity? A hot oil bath and patience for even frying—no shortcuts here.

The beauty of these donuts is in their simplicity: just potatoes, flour, sugar, and a pinch of salt. No fancy mix-ins or elaborate techniques—just the kind of recipe your great-grandmother might have made.

The potatoes give them a subtle earthiness that balances the sweetness, while the frying process delivers that perfectly crispy exterior. Unlike today’s cake-like donuts, these are light, airy, and satisfyingly crunchy, with a hint of nostalgia in every bite.

What makes this recipe special is how it captures the essence of early 20th-century baking—no electric mixers, no pre-measured ingredients, just good old-fashioned technique. The donuts hold their shape beautifully, with a golden-brown crust that shatters when you bite in.

Serve them warm with a dusting of powdered sugar or a drizzle of honey for that old-fashioned touch. The best part? They’re just as delicious today as they were over a century ago.

Ready to bring a taste of history to your kitchen? These donuts are perfect for breakfast, dessert, or even a nostalgic snack. The recipe is foolproof, but the magic happens in the frying—so grab your deep fryer and get ready for a trip back in time.

Here’s how to make them just right.

Ingredients for 1915 potato donut

Twelve ingredients transform humble potatoes into nostalgic, golden donuts with a crispy exterior and tender crumb.

The potatoes are the foundation—Russet is ideal for its starch content, but Yukon Gold adds subtle sweetness. Boil them whole with skins on for texture, then mash until completely smooth (no lumps!). Grocery stores often carry pre-boiled potatoes in the refrigerated section, but homemade yields better results. For the flour, King Arthur or Gold Medal brands are reliable for consistent texture. The sugar should be fine grain—Domino works well, but avoid powdered sugar here unless specified. Butter matters too: Plugrá or Land O’Lakes are excellent choices, but use cold cubes to prevent melting during prep.

No Russet potatoes? Yukon Gold or Idaho potatoes will work, though texture may vary slightly. Short on baking powder? Baking soda at half the amount plus 1 tsp cream of tartar substitutes effectively. The vanilla extract can be omitted if needed, but the nutmeg and lemon zest add depth—substitute 0.5 tsp cinnamon if unavailable. For the oil, vegetable or canola oil are standard, but peanut oil delivers superior crispiness. If you lack powdered sugar for dusting, a light drizzle of honey or simple syrup offers a similar finish. The eggs must be room temperature for proper emulsification—cold eggs cause dense donuts.

Store the dry ingredients—flour, sugar, baking powder—in airtight containers for up to 6 months. The mashed potatoes can be refrigerated for 2 days before frying, covered tightly to prevent drying. Once fried, donuts stay crispy for 3 hours at room temperature if kept in a single layer. For longer storage, freeze shaped donuts on a tray before transferring to a bag—reheat in a 350°F oven for 5 minutes to restore crispness. The oil can be reused 2-3 times if filtered between batches, but discard if it develops a burnt smell.

Step-by-step instructions for 1915-Style potato donuts

Here’s how to recreate the legendary vintage donuts with that signature crisp exterior and tender crumb.

Peel the 2 lbs Russet Potatoes and cut them into 1-inch chunks. Place them in a large pot and cover with cold water by 2 inches. Add 1 tsp Salt to the water and bring to a boil over medium-high heat. Once boiling, reduce heat to medium and simmer for 15 minutes until fork-tender.

Drain the potatoes thoroughly, then return them to the pot. Using a potato masher or ricer, mash until completely smooth with no lumps. Let the mashed potatoes cool to room temperature before proceeding—this prevents the butter from melting prematurely. The texture should be silky and free of any moisture, resembling thick pudding.

In a large mixing bowl, combine the cooled mashed potatoes with 2 cups All-Purpose Flour, 1 cup Granulated Sugar, 1 tsp Baking Powder, and 1 tsp Lemon Zest. Mix thoroughly with a wooden spoon or rubber spatula until fully incorporated. The batter should resemble thick pancake batter with a slightly grainy texture from the potatoes.

In a separate bowl, beat the 2 whole Large Eggs until just combined. Cut the 0.5 cup Unsalted Butter into small cubes and let them sit at room temperature for 10 minutes. Add the eggs and butter to the potato mixture along with 0.5 tsp Vanilla Extract and 0.25 tsp Ground Nutmeg. Mix gently until all ingredients are evenly distributed. The batter should be thick but pourable—if it’s too stiff, add 1 tablespoon of cold water at a time until it reaches the right consistency.

Heat 4 cups Vegetable Oil in a deep fryer or heavy pot to 350°F. Use a candy or deep-fry thermometer to monitor the temperature—it should remain steady at 350°F throughout cooking. The oil should shimmer gently but not smoke excessively.

Using a piping bag fitted with a large round tip (or a heavy-duty zip-top bag with a corner snipped off), pipe 2-inch diameter donuts directly into the hot oil. Fry 2-3 donuts at a time to avoid overcrowding, which lowers the oil temperature. Cook for 3-4 minutes per side until deep golden brown with a crisp exterior. The donuts are done when they float to the surface and maintain their shape when gently prodded with a wooden chopstick. Remove with a slotted spoon and drain on a wire rack lined with paper towels.

While the donuts are still warm, sift 1 cup Powdered Sugar over a fine-mesh sieve. Place the fried donuts on a wire rack set over a plate and gently dust each one with the powdered sugar. Tap the rack lightly to ensure even coating. The sugar will melt slightly from the residual heat, creating that signature vintage glaze.

Serve immediately for the ultimate texture contrast—crispy exterior, tender interior, and that classic powdered sugar finish. These donuts are best enjoyed fresh, as they lose their crispness as they cool. For extra authenticity, pair with a glass of cold milk or a cup of strong black coffee.

Flavor customization for this recipe

Classic Spiced Twist

Add ½ tsp ground cinnamon and ¼ tsp freshly grated nutmeg to the dry ingredients for that nostalgic spiced donut flavor. I love using Penzeys Spices for their high-quality blends—just a pinch makes all the difference.

For warmth, swap the vanilla extract for 1 tsp bourbon or rum (like Buffalo Trace) and reduce the sugar slightly to ¾ cup to balance the alcohol’s sweetness. 🌶️

Citrus Zest Variations

Brighten up these donuts with extra citrus—try 1 tsp orange zest or ½ tsp lime zest instead of lemon. The acidity cuts through the richness beautifully. For a tropical twist, add ½ tsp grated ginger along with the lemon zest.
