🍩 Crispy Sourdough Discard Churros — Cinnamon Sugar & Ready in 45 Minutes

🍩 Crispy Sourdough Discard Churros

Golden. Crunchy. Rolled in cinnamon sugar while they're still crackling.

These are the churros that make your discard jar the most popular jar in the kitchen.

Makes ~18 Churros  •  Beginner Friendly  •  Discard-Powered  •  Ready in ~45 Minutes

Let's get one thing straight: sourdough discard churros are not some sad "healthier churro" compromise. They're the real thing — shattering-crisp ridges, custardy centers, and a cinnamon-sugar shell that clings to every groove. The discard is the secret weapon. It adds a whisper of tang that makes the cinnamon pop harder and turns a fairground treat into something with actual depth.

The technique sounds fancy (a choux dough!) but it's five minutes of stirring in a saucepan. If you've ever boiled pasta water, you have the skills. Pipe, fry, roll, eat. Warm. Always warm.

🍩 Why You'll Love These Churros

• ✔ Uses a full half-cup of discard
• ✔ No rise, no rest, no waiting — fry them the same hour
• ✔ Shatteringly crisp outside, tender and custardy inside
• ✔ Cinnamon sugar clings to the ridges like it was engineered for it
• ✔ Way easier than they look — one saucepan, one piping bag
• ✔ Optional 2-minute chocolate dip that will ruin regular dessert for you

🍩 Crispy Sourdough Discard Churros

Churro Dough

• 180 g water (about ¾ cup)
• 57 g unsalted butter (about 4 tbsp)
• 25 g granulated sugar (about 2 tbsp)
• 3 g fine sea salt (about ½ tsp)
• 5 g vanilla extract (about 1 tsp)
• 120 g all-purpose flour (about 1 cup)
• 120 g sourdough discard (about ½ cup, unfed is perfect)
• 2 large eggs, room temperature

Cinnamon Sugar Coating

• 100 g granulated sugar (about ½ cup)
• 5 g ground cinnamon (about 2 tsp)

For Frying

• Neutral oil with a high smoke point — vegetable, canola, or peanut — enough for about 2 inches in a heavy pot
• A piping bag fitted with a large open-star tip (this is what makes the ridges — don't skip it)
• Clean kitchen scissors for snipping
• A plate lined with paper towels
• A clip-on thermometer if you have one (recommended, not mandatory)

Quick Chocolate Dip (optional but strongly advised)

• 100 g dark or semisweet chocolate, chopped (about 3.5 oz)
• 120 g heavy cream (about ½ cup)

🥣 Step 1: Set Up Your Station

Frying moves fast, so get everything in place first. Stir the cinnamon sugar together in a wide, shallow bowl. Line a plate with paper towels and set it right next to your stove. Fit the piping bag with the star tip and set it aside — you'll fill it later.

Pour the oil into a heavy-bottomed pot or Dutch oven — about 2 inches deep, and never more than halfway up the sides. Oil expands and bubbles when food hits it, and you do not want a volcano.

Safety is non-negotiable here: hot oil is serious business. Keep the handle turned inward, keep kids and pets out of the splash zone, and never leave the pot unattended. Everything below assumes you're giving the oil your full attention.

🔥 Step 2: Make the Choux Base

Combine the water, butter, sugar, salt, and vanilla in a medium saucepan over medium-high heat. Bring it to a full rolling boil, stirring once or twice, until the butter is completely melted.

Dump in the flour and the sourdough discard all at once and start stirring like you mean it. A wooden spoon or stiff spatula works best. Within 30–60 seconds it will go from a shaggy mess to a thick dough that pulls away from the sides and follows the spoon around the pan.

Keep stirring for another 60–90 seconds. You're looking for a thin film of dough on the bottom of the pan — that's your sign the moisture has cooked down enough. This drying step is what keeps the churros crisp instead of soggy.

Beginner Tip: If the dough is sticking hard to the bottom and browning, your heat is too high — but the dough itself is almost certainly fine. Turn the heat down and keep going.

🥚 Step 3: Cool, Then Beat in the Eggs

Scrape the dough into a mixing bowl and let it cool for 5–10 minutes. You want it warm, not hot — if it's steaming hard, the eggs will scramble when they hit it. Touch test: warm enough to be cozy, cool enough to hold your finger in.

Add the eggs one at a time, beating hard after each. It will look alarming at first — the egg goes slimy and slippery and the dough breaks into chunks. Keep beating. It comes back together into a thick, glossy paste. This is the choux magic; trust the process.

The finished dough should be thick enough to hold its shape but loose enough to pipe — when you lift the spoon, it should slowly fall off in a ribbon rather than plop. If it's still stiff after two eggs, beat a third egg in a small bowl and add it a spoonful at a time until the texture is right.

Beginner Tip: A stand mixer with the paddle attachment makes this effortless, but a wooden spoon and some enthusiasm work just as well. Your arm gets a workout; the churros are worth it.

🌡️ Step 4: Heat the Oil

Heat the oil to 350–375°F (175–190°C). A thermometer is the stress-free route — temperature is genuinely the difference between churros that are crisp and churros that are greasy.

No thermometer? Drop a tiny dab of dough in. It should sizzle immediately, turn golden in about a minute, and rise to the surface. If it browns in seconds, the oil is too hot. If it sinks and barely bubbles, it's too cool.

Do not overcrowd. Fry 3–4 churros at a time max. Too many at once drops the oil temperature and you get greasy, pale churros instead of golden, crisp ones. Patience between batches pays off.

🫗 Step 5: Pipe, Snip & Fry

Fill the piping bag with dough. Pipe 4–6 inch strips directly over the hot oil, snipping each one off with the kitchen scissors. Keep your piping hand high enough that oil doesn't splash you — a good 3–4 inches above the surface.

Fry for 2–4 minutes total, turning once or twice, until they're a deep golden brown all over. The ridges from the star tip are doing the real work here — more surface area means more crunch.

Lift them out with a slotted spoon or spider strainer, let the oil drip off for a few seconds, and land them on the paper towels.

Beginner Tip: The first batch is always your test batch. Eat it immediately (quality control is important work) and adjust: paler than you want? Let the next batch go a little longer. Browning too fast? Nudge the heat down.

✨ Step 6: Roll in Cinnamon Sugar While Hot

This step has a time limit: roll each churro in the cinnamon sugar within a minute of frying, while it's still hot and steaming. That's when the coating sticks. A cooled churro shrugs the sugar right off.

Toss them gently in the bowl, turn them to coat every side, and pile them up. Eat them warm — like, right now. Churros are a hot-out-of-the-fryer situation and everyone at your house knows it.

🍫 Step 7: The Chocolate Dip (2 Minutes)

While a batch is frying, heat the cream in a small saucepan until it just starts to steam — don't boil it. Pour it over the chopped chocolate, wait 60 seconds, and stir until glossy. That's the whole recipe.

Pro-Level Move: add a pinch of cinnamon and the tiniest pinch of cayenne to the dip for a Mexican-chocolate vibe. A pinch of flaky sea salt on top is also elite.

👩🍳 Squirrelly Girl Baker's Tips

🍩 1. The star tip is not optional. A round tip makes dough sticks. The open-star tip cuts the ridges that get shatter-crisp and hold the cinnamon sugar. Big difference, tiny piece of metal.

🌡️ 2. Temperature is everything. Too cool and the churros drink oil and turn greasy. Too hot and they go dark before the center cooks through. That 350–375°F window is the whole game.

🥚 3. Room-temperature eggs mix in faster. Cold eggs fight the dough and can make it lumpy. Set them on the counter when you start — that's all the planning required.

🫗 4. Fill the piping bag like a pro. Fold the top of the bag down over your hand to make a cuff, spoon the dough in, then unfold and twist. Way less mess than trying to shove dough into a floppy bag.

🔁 5. Reuse the oil. Let it cool completely, strain it through a fine-mesh sieve or cheesecloth into a jar, and store it in a cool dark spot. It's good for several more frying sessions — just never mix it with anything else.

🧊 Make Them Ahead

Churros are at their peak in the first 30 minutes after frying — that's the truth, and any recipe that tells you otherwise is selling something. That said, you have options.

The raw dough holds beautifully: keep it in the piping bag (twist the top shut) in the fridge for up to 24 hours, then fry straight from cold — add about a minute to the fry time. This is the move for dinner parties: do the messy part in the afternoon, fry fresh when people arrive.

Leftover fried churros keep at room temperature in a loosely covered container for up to a day. They will not be as crisp. Revive them in a 375°F oven or air fryer for 3–4 minutes and they come surprisingly close to fresh.

Do not freeze fried churros. The cinnamon sugar turns to mush on thawing and it's genuinely sad. Freeze the raw dough in the piping bag instead — thaw in the fridge overnight and fry fresh.

🚨 Sourdough Churro Troubleshooting

My churros are greasy and pale.

Your oil was too cool, or you overcrowded the pot. Both drop the temperature and the churros soak up oil instead of crisping in it. Fewer churros per batch, thermometer in the oil, patience between batches.

They're dark on the outside but doughy inside.

Oil too hot. The outside set before the inside cooked through. Drop the heat back into the 350–375°F window and give them the full 2–4 minutes.

My churros puffed up and burst open while frying.

Classic choux problem — usually trapped air pockets or a tip that sealed the ends. Use a wide open-star tip, don't pipe them too thick, and make sure the dough isn't under-dried in Step 2. Small bursts are cosmetic; the churro still tastes incredible.

The dough won't pipe — it's too thick.

You likely needed that third egg. Beat one more egg and add it a spoonful at a time until the dough falls off the spoon in a slow ribbon. Choux dough should be pipeable, not scoopable.

The cinnamon sugar won't stick.

You waited too long. The coating only grabs onto a hot, steamy churro. Next batch: straight from the oil to the paper towel for 10 seconds, then straight into the sugar bowl.

My churros came out dense instead of airy.

The dough was probably under-dried in the pan (skipped the 60–90 second stir after it formed a ball) or the eggs were under-beaten. Both are easy fixes on the next batch — and even a dense churro rolled in cinnamon sugar is still excellent.

⚠️ Baker's Warning

Making sourdough churros from scratch has a predictable side effect.

You will be asked to "just whip up a batch" for every gathering from now on.

And once people realize the discard jar is involved…

You're officially the churro person.

❓ FAQ: Sourdough Discard Churros

Can I use active starter instead of discard?

Yes — active starter works exactly the same here. But discard is honestly the better move: the dough doesn't need any fermentation lift (the eggs and steam do the puffing), so you're putting would-be-waste to delicious use.

Can I bake or air-fry these instead of deep-frying?

You can, with honest expectations. Pipe onto a parchment-lined sheet, brush or spray lightly with oil, and bake at 425°F for about 20 minutes, or air-fry at 400°F for 8–10 minutes — then roll in cinnamon sugar while hot. They'll be tasty and much lighter, but they won't have the shatter-crisp shell of a fried churro. Deep-frying is what makes a churro a churro.

What oil is best for frying churros?

Any neutral oil with a high smoke point: vegetable, canola, or peanut oil all work great. Avoid olive oil — its flavor is too strong and its smoke point is too low for this job.

Why did my churros explode in the fryer?

Steam trapped inside the dough with nowhere to go. A wide open-star tip prevents this — the ridges give steam escape routes. Also make sure you dried the dough properly in the pan and beat the eggs in fully. Minor bursting is cosmetic; keep frying.

How long do churros stay fresh?

About 30 minutes at peak crispness, a day at room temperature in a loosely covered container. Reheat at 375°F for 3–4 minutes to bring back most of the crunch. The raw dough, though, keeps 24 hours in the fridge — fry fresh for the best result.

Can I make the dough ahead of time?

Absolutely — this is the best make-ahead trick for churros. Keep the filled piping bag in the fridge for up to 24 hours and fry straight from cold, adding about a minute to the cook time.

❤️ Happy Frying!

Heat the oil.

Pipe with confidence.

Roll them while they're hot.

Eat at least two before anyone else gets to the plate.

And when someone asks for the recipe, just smile and say, "It's the sourdough."
