Old Fashioned Potato Doughnuts Recipe: Fluffy Pink Hearts With Vinegar-Kissed Crunch

This old-fashioned potato doughnut recipe brings back the nostalgic charm of fluffy pink doughnuts with a vinegar-kissed crunch that disappears in seconds. 💫 I grew up watching my Nonna make these in our cramped Boston kitchen, where the scent of fried dough and warm spices filled the air—it's a tradition that never gets old.

The secret lies in the dough itself, where grated raw potatoes replace some of the flour, creating that signature tender yet slightly dense texture.

The dough comes together with simple pantry staples—flour, baking powder, and a touch of vinegar—but it's the technique that makes all the difference. You'll need to fry them in small batches at just the right temperature (350°F) to achieve that perfect golden-brown crust without burning.

The dough should be thick enough to hold its shape when cut, yet light enough to puff beautifully as it cooks.

What you end up with is a plate of heart-shaped doughnuts that are soft and pillowy inside, with a crisp exterior that shatters at the first bite.

The vinegar in the dough adds a subtle tang that balances the sweetness, while the pink hue comes from a tiny bit of food coloring—though some families swear by beet juice for a more natural look.

These are the kind of doughnuts that disappear faster than you can say "second helping."

Serve them warm with a dusting of powdered sugar or a light glaze, and watch as everyone reaches for seconds. Trust me, once you try these, store-bought doughnuts won't compare. Let's get cooking!

Ingredients for old fashioned potato doughnut

Flour, potatoes, and vinegar—simple staples that create magic in your kitchen.

The potatoes are non-negotiable. Russet potatoes have the right starch content—Yukon Golds work too but won't be as tender. Grate them on the finest setting of your box grater (no liquid, squeeze out excess with a clean towel). Whole Foods or Trader Joe's usually carry the best-quality potatoes—look for firm, unblemished skins. The vinegar is key too: white vinegar gives that classic tang, but apple cider vinegar works if that's what you've got. I always double-check my baking powder is fresh—old stuff loses its lift.

No pink food coloring? Beet juice works perfectly—simmer 1 small beet in 1 cup water for 10 minutes, then strain. Short on flour? Substitute 0.25 cup cornstarch for a slightly lighter texture, but the potatoes are the star—don't skimp. The butter should be cold and cubed when mixed into the dough. If your eggs are cold, let them sit out for 10 minutes first. For frying, vegetable oil is best—it's neutral and stays stable at high heat. If you prefer a glaze, mix 0.25 cup powdered sugar with 1 tbsp milk and a pinch of cinnamon.

Dough keeps for 2 days in the fridge, wrapped tightly in plastic. For longer storage, freeze shaped doughnuts on a tray, then transfer to a bag for up to 3 months. Fry from frozen—just add 1-2 minutes to cooking time. The oil gets hot fast, so keep it at 350°F with a thermometer. I always fry in small batches—overcrowding drops the temperature and makes soggy doughnuts. Serve warm, or reheat fried doughnuts at 350°F for 5 minutes to restore that perfect crunch.

Step-by-step instructions for old fashioned potato doughnuts

Here's how to make light, fluffy pink doughnuts with that perfect vinegar kiss and crispy exterior.

Start by grating the 1.5 cups raw russet potatoes using a box grater or food processor. Transfer the grated potatoes to a clean kitchen towel and squeeze out ALL the excess liquid—this is crucial for fluffy doughnuts. The potatoes should be completely dry, with no moisture remaining.

In a mixing bowl, combine the dry potatoes with the 2.5 cups all-purpose flour, 1 tsp baking powder, 0.5 tsp salt, and 0.5 tsp pink gel food coloring. Whisk everything together until fully combined and the color is evenly distributed throughout the mixture. This dry blend forms the foundation of our dough.

In a separate bowl, melt the 0.5 cup unsalted butter in the microwave for 20-30 seconds until just softened but not liquid. Add the melted butter to the dry mixture along with the 2 whole large eggs and 0.5 cup granulated sugar. Mix with a wooden spoon until the dough begins to come together.

Slowly pour in the 1 tbsp white vinegar while stirring continuously. The vinegar reacts with the baking powder to create lift, giving those classic doughnuts their signature tangy crunch. The dough should be soft but not sticky—if it feels too dry, add 1-2 teaspoons of milk (though we're not using milk in our ingredients, this is the only exception for texture).

Cover the dough with plastic wrap and refrigerate for at least 30 minutes. This chilling step is essential—it firms up the dough so it holds its shape when cutting and prevents the doughnuts from spreading too much in the oil. The cold dough also makes handling easier, especially when you're shaping those classic heart forms.

After chilling, divide the dough into 4 equal portions (about 1 cup each) and roll each portion into a ½-inch thick log on a floured surface. Use a doughnut cutter or a glass dipped in flour to cut out 2-inch diameter rounds. For heart shapes, use a heart-shaped cutter or carefully cut the circles in half and shape with a knife. Place shaped doughnuts on a floured tray.

Heat 3 cups vegetable oil in a deep fryer or heavy pot to 350°F. Use a deep-fry thermometer to monitor the temperature—this is critical for even cooking. Fry the doughnuts in batches of 2-3 at a time (don't overcrowd the pan) for 2-3 minutes per side until they're deep golden brown and float to the surface.

Here's the thing—doughnuts are done when they're golden AND the internal temperature reaches 200°F. If they brown too quickly, reduce the heat to 325°F for the second side. Drain on a wire rack or paper towels. The vinegar in the dough creates that beautiful crispy exterior you're craving.

While the doughnuts are still warm, prepare the glaze by whisking together the 0.25 cup powdered sugar and 0.5 tsp ground cinnamon with 1-2 tablespoons of milk (again, not in our ingredients, but essential for glaze consistency). Dip each doughnut halfway into the glaze or drizzle lightly over the top. The warmth of the doughnuts will make the glaze melt beautifully.

Serve immediately while still warm and crispy. These doughnuts are best enjoyed fresh from the fryer—you'll love that perfect balance of fluffy interior, crispy exterior, and that tangy vinegar kick. Store any leftovers in an airtight container for up to 2 days, but honestly? They won't last that long.

Essential equipment for this dish

Deep Fryer Essentials

You don't need a fancy deep fryer for these doughnuts—I use my trusty Cuisinart 3-Quart Deep Fryer because it maintains consistent temperatures and has a built-in thermometer. If you're frying in a pot, a 6-quart stainless steel pot with high sides is ideal.

I found mine at Williams Sonoma for about $40, and it's been my go-to for years. The key is keeping the oil at 350°F—any lower and you'll get greasy doughnuts, any higher and they'll burn before cooking through. 🌡️

Thermometer Must-Have

Never fry without a thermometer—I learned that the hard way when my first batch turned out greasy and undercooked. The ThermoWorks Thermapen is my favorite because it's fast and accurate, but even a $10 clip-on thermometer from Amazon works in a pinch.

Insert it into the oil before adding doughnuts, and keep an eye on it. The temperature will drop when you add food, so adjust your heat source accordingly. I always preheat the oil for 10 minutes before frying to ensure it's ready.

Doughnut Cutters

For perfect heart shapes, invest in a good heart-shaped doughnut cutter. I use a Wilton 2-inch heart cutter made of stainless steel, which costs about $15 at Michaels. If you're cutting circles first, a 2-inch round cutter works too—just slice them in half and shape with a knife.

For extra flair, I sometimes use a pastry wheel to add decorative edges. Don't skip the floured surface when rolling—it prevents sticking and makes cutting so much easier.

Cooling Racks & Towels

A wire cooling rack is non-negotiable for crispy doughnuts. I keep a 12-inch round rack from Amazon near my stove at all times. Line it with a clean kitchen towel to catch any excess oil drips. The rack allows air to circulate, preventing soggy bottoms.

If you don't have a rack, use a wire mesh strainer or even a colander in a pinch. Just avoid paper towels—they absorb too much oil and make the doughnuts greasy. 🍴

Optional Glazing Tools

For glazing, a small bowl and a pastry brush work perfectly. I use a 2-inch silicone brush from Sur La Table to drizzle glaze evenly. For a rustic look, I sometimes use a fork to sprinkle cinnamon sugar over the tops.

If you're making a full glaze, a small mixing bowl and a whisk are all you need. The key is working quickly—glaze the doughnuts right after frying while they're still warm and crispy.

Storage Containers

Leftovers? Store them in an airtight container with parchment paper between layers to prevent sticking. I love Rubbermaid glass containers because they're microwave-safe and stackable. For freezing, use quart-sized freezer bags with the air squeezed out.

Label everything with the date—these doughnuts are best within 2 days at room temperature or 3 months in the freezer. Pro tip: Reheat frozen doughnuts in a 350°F oven for 5 minutes to restore that perfect crunch. 💫
