There’s a moment—about 30 seconds after these donut holes leave the hot oil—when the cinnamon-sugar crust is still crackling and the interior is so tender it practically sighs when you bite in. That moment is the reason I make a double batch every single time. My grandmother called them “pillow puffs,” and she’d serve them in a paper bag shaken with sugar so every corner was coated. Today, I line them up on a platter, steam rising like little beacons, and watch them disappear before the coffee’s even finished brewing. Whether you’re hosting a lazy Sunday brunch, need a show-stopping dessert for game night, or simply want your kitchen to smell like the best corner bakery in town, this recipe is your ticket.

Why This Recipe Works

Buttermilk Magic: The slight tang tenderizes the crumb and reacts with baking powder for extra lift.
Two-Temperature Fry: A quick sear at 375 °F seals the crust, then 350 °F finishes the interior without burning the sugar.
Double-Coat Method: A hot dunk in melted butter followed by a tumble in cinnamon sugar creates that bakery-style lacquered shell.
Small Batch Friendly: The dough keeps beautifully in the fridge for 24 hours, so you can fry fresh holes on demand.
No Yeast, No Waiting: Baking-powder leavened dough means you go from mixing bowl to mouth in under 30 minutes.
Make-Ahead Sugar Blend: Whip up a jar of the cinnamon sugar and store it with your spices—breakfast just got faster.

Ingredients You'll Need

Great donut holes start with great ingredients—here’s what to look for and how to swap if you’re in a pinch.

All-Purpose Flour: I use 11–11.5 % protein flour (King Arthur is my go-to) for enough structure to hold the spherical shape without turning chewy. If you’re in a humid climate, start with 2 tablespoons less liquid and add only as needed.

Granulated Sugar: Standard white sugar sweetens the dough and helps the exterior caramelize. Organic cane sugar works, but avoid superfine; it dissolves too fast and can create a cracked crust.

Baking Powder & Soda: The duo gives a quick, high rise. Check the expiration dates—if either has been open longer than 6 months, spring for fresh cans.

Ground Cinnamon: Look for Vietnamese or Saigon cinnamon for higher essential-oil content and that nostalgic red-hot aroma. Buy in small quantities and store in the freezer to preserve punch.

Whole Nutmeg (optional but heavenly): A few swipes on a microplane add warm complexity without screaming “eggnog.”

Buttermilk: Real, full-fat buttermilk tenderizes like nothing else. No buttermilk? Stir 1 tablespoon lemon juice or white vinegar into 1 cup whole milk and let stand 5 minutes.

Unsalted Butter: You’ll melt some into the dough and more for the post-fry bath. European-style (82 % fat) browns beautifully and adds a nutty undertone.

Eggs: Large, room-temperature eggs emulsify the batter. Cold eggs can shock melted butter into solid bits.

Neutral Oil for Frying: Peanut, canola, or sunflower all have high smoke points and neutral flavor. Save the olive oil for another project.

Vanilla Extract: A full tablespoon rounds out the spice notes. Swap in maple extract for a autumnal twist.

How to Make Warm Cinnamon Sugar Donut Holes with Cinnamon Sugar Coating

Whisk the Dry Base

In a large bowl, combine 2 ½ cups (315 g) flour, ⅓ cup (67 g) granulated sugar, 2 ½ teaspoons baking powder, ½ teaspoon baking soda, 1 teaspoon fine sea salt, 1 teaspoon cinnamon, and ¼ teaspoon freshly grated nutmeg. Whisk for a full 30 seconds to distribute leaveners; pockets of soda taste metallic.

Warm the Wet Team

In a small saucepan, melt 4 tablespoons butter; keep it on the heat until it just starts to brown and smell nutty—about 2 minutes after melting. Pour into a medium bowl and immediately whisk in ¾ cup buttermilk, 2 large eggs, and 1 tablespoon vanilla. The mixture should feel slightly warm to the touch; if it’s hot, let it cool so the eggs don’t scramble.

Bring the Dough Together

Make a well in the dry ingredients, pour in the wet, and fold with a silicone spatula just until a shaggy dough forms. Add the remaining ¼ cup flour a tablespoon at a time until the dough clears the sides of the bowl but is still soft and tacky—think play-doh, not bread dough. Over-mixing develops gluten and yields tough holes.

Rest & Chill (The Secret Step)

Cover the bowl with plastic wrap pressed directly onto the surface and refrigerate at least 20 minutes or up to 24 hours. A short rest hydrates flour evenly and firms the butter so the balls hold their shape when dropped into hot oil.

Portion Uniform Balls

Scoop the chilled dough with a 1-tablespoon cookie scoop, leveled. Roll lightly between damp palms to seal cracks; imperfect spheres fry into charming rustic shapes. Place on a parchment-lined sheet dusted with flour to prevent sticking.

Heat Oil Safely

Fill a heavy pot with 2 inches of oil. Clip on a candy thermometer and heat to 375 °F over medium-high. Maintain the temperature; a 20-degree drop equals greasy holes, while too-hot oil browns the outside before the inside cooks.

Fry in Small Batches

Slide 5–6 balls into the oil; crowding drops temperature. Fry 45 seconds, gently roll with a spider strainer, then another 45–60 seconds until deep golden. Transfer to a wire rack set over a sheet pan. Reheat oil to 375 °F between batches.

The Double-Coat Finish

While still hot, brush each hole generously with the remaining 4 tablespoons melted butter. Immediately tumble in a shallow bowl of cinnamon sugar (1 cup sugar + 2 tablespoons cinnamon). The sugar will melt slightly, then set into a crunchy shell as it cools.

Serve Immediately

Pile them high on a warm platter with extra cinnamon sugar for dipping. They’re best within 30 minutes of frying, but keep reading for reheating tricks.

Expert Tips

Oil Thermometer = Insurance

A $15 candy thermometer pays for itself with the first non-greasy batch. Clip it to the pot and adjust heat in tiny increments.

Butter vs. Oil for Coating

Butter gives classic flavor but can sog if stored. For picnic batches, brush with neutral oil before sugaring—they’ll stay crisp longer.

Reuse Your Oil

Strain through cheesecloth, cool, and store in the original bottle. It’s good for 3–4 fry sessions or until it darkens or smells off.

Freeze Pre-Portioned Dough

Flash-freeze scooped balls on a tray, then bag. Fry from frozen—just add 30 extra seconds and keep oil at 350 °F throughout.

Flavor Fat

Infuse your melted butter with a split vanilla bean or a strip of orange zest while it browns—strain before brushing for subtle aroma.

Safety First

Keep a lid handy for the pot; if oil smokes excessively, slide the lid on (without water!) to deprive flames of oxygen.

Variations to Try

Apple Cider Churro Holes: Replace buttermilk with reduced apple cider (simmer 1 cup down to ¾ cup, cool). Add ½ teaspoon cinnamon to dough and roll finished holes in cinnamon-sugar mixed with ¼ cup freeze-dried apple dust.
Chocolate Hazelnut Stuffed: Press a frozen ball of Nutella into the center of each dough ball before frying. Seal well to prevent leaking.
Pumpkin Spice: Sub ¼ cup flour with ¼ cup pumpkin puree; add ½ teaspoon each ginger and nutmeg. Dust with cinnamon-cardamom sugar.
Gluten-Free: Replace flour with 1:1 baking blend plus ½ teaspoon xanthan gum. Rest dough 30 minutes so grains hydrate.
Vegan: Swap buttermilk for soy milk curdled with lemon, use coconut oil instead of butter, and replace eggs with 2 tablespoons aquafaba.

Storage Tips

Like most fried foods, these shine fresh, but life happens and leftovers deserve love too.

Room Temperature

Cool completely, then store in a paper-towel-lined container with the lid ajar up to 24 hours. Re-crisp 4 minutes at 350 °F in the air fryer.

Refrigerator

Refrigeration encourages staling; skip it unless filled with dairy. If you must, wrap tightly and reheat as above.

Freezer (Best Bet)

Freeze sugared holes in a single layer, then bag. Reheat from frozen 6 minutes at 375 °F in the air fryer; re-sugar while hot.

Make-Ahead Dough

Portion and refrigerate up to 24 hours or freeze up to 1 month. Fry directly from chilled or frozen, adjusting time.

Frequently Asked Questions

Oil temperature dropped too low. Use a thermometer and fry small batches. Also, over-mixed dough develops gluten, creating holes that leak and soak up fat.

Yes, but they’ll be muffin-like. Bake in a mini-muffin tin at 400 °F for 9–10 minutes. Brush with butter and coat in sugar for a similar effect.

A cake tester or toothpick inserted in the center should come out with a few moist crumbs—not wet batter. They’ll finish cooking slightly from residual heat.

The holes must be hot and lightly butter-brushed. If they cool, warm 5 seconds in the microwave, brush again, and re-coat.

Absolutely. Mix in a stand mixer on low after the rest period. Fry in two pots to maintain oil temperature, or fry sequentially and keep finished holes warm in a 200 °F oven on a rack.

Air fryer 350 °F for 3–4 minutes, shaking halfway. Oven works too: 350 °F on a wire rack for 6 minutes. Avoid the microwave unless you like gummy textures.
