🧈 Sourdough Buttermilk Biscuits

Tall. Flaky. Butter pulls in a single, gorgeous layer.

These are the biscuits that finally make your discard jar earn its spot on the counter.

Makes 10 Biscuits  •  Beginner Friendly  •  Discard-Powered  •  Ready in ~40 Minutes

Here's what nobody tells you about sourdough buttermilk biscuits: they are easier than bread, faster than a loaf, and the discard does something magical — it tenderizes the crumb while the buttermilk brings that classic tang. Cold butter turns to steam in a hot oven, and you get layers. Actual pull-apart layers.

No yeast. No proofing. No babysitting dough for hours. Mix, fold, cut, bake — tall golden biscuits in about 40 minutes.

🧈 Sourdough Buttermilk Biscuits

Biscuit Dough

• 240 g sourdough discard (about 1 cup, unfed is perfect)
• 250 g all-purpose flour (about 2 cups), plus more for dusting
• 120 g cold buttermilk (about ½ cup), plus a little extra for brushing
• 113 g very cold unsalted butter (8 tbsp / 1 stick), cubed or grated
• 12 g baking powder (about 1 tbsp)
• 5 g baking soda (about 1 tsp)
• 8 g granulated sugar (about 2 tsp)
• 6 g fine sea salt (about 1 tsp)

For Finishing

• 15 g melted butter (about 1 tbsp) for brushing the tops
• A pinch of flaky salt, if you're feeling fancy

🥣 Step 1: Chill Everything & Preheat

Cold is the whole game in biscuit-making. If your kitchen is warm, pop your cubed butter in the freezer for 10 minutes before you start. Keep the buttermilk and discard in the fridge until the exact moment you need them.

Meanwhile, heat your oven to 425°F (220°C). Line a baking sheet with parchment paper.

Beginner Tip: The colder your butter, the flakier your biscuits. When little butter chunks hit the hot oven, the water in them turns to steam — and steam is what pushes the dough into layers. Warm butter melts into the flour instead, and you get hockey pucks. Cold wins.

🧈 Step 2: Cut in the Butter

Whisk the flour, baking powder, baking soda, sugar, and salt together in a large bowl.

Add the cold butter cubes and cut them in with a pastry cutter or your fingertips until the mixture looks like coarse crumbs with plenty of pea-sized butter bits scattered through. Don't overwork it — those chunky butter pieces are the future layers of your biscuits.

Pro-Level Move: Grate the frozen butter on a box grater instead of cubing it. Shredded butter distributes in seconds with almost no handling, and your hands stay warm-button-free.

🥣 Step 3: Mix the Dough

Whisk the sourdough discard and cold buttermilk together until mostly smooth, then pour it into the flour-butter mixture.

Stir gently with a spatula until a shaggy dough just comes together — about 30 seconds. It should look rough and barely held together, not smooth. If there are dry floury patches, add buttermilk a tablespoon at a time.

Beginner Tip: Under-mixing is your friend here. A shaggy, ugly dough makes a tender biscuit. A smooth, well-kneaded dough makes a tough one. Walk away while you're still slightly worried it needs one more stir.

📜 Step 4: Fold for Layers

Turn the dough out onto a lightly floured surface and pat it into a rough rectangle, about 1 inch thick.

Now the magic move: fold the bottom third up, then the top third down over it, like a letter. Pat it back out to 1 inch thick. Repeat the fold 2 more times. That's it — you just laminated your biscuits, bakery-style, in about 2 minutes.

If the dough gets warm or sticky at any point, slide it onto the baking sheet and chill it in the fridge for 10 minutes. Cold butter is sacred. Protect it.

⭕ Step 5: Cut Tall

Pat the folded dough to a final thickness of 1 inch — thicker than your instincts say. Thick dough = tall biscuits.

Using a floured 2.5-inch biscuit cutter (or a sharp knife for square biscuits), cut straight down without twisting. Twisting seals the edges and robs you of rise. Place the rounds on the prepared baking sheet with the sides just barely touching — they'll climb upward instead of spreading outward.

Gently press the scraps together (don't re-knead) for 1–2 extra biscuits. They'll be a little less pretty and equally delicious.

Beginner Tip: Brush the tops lightly with a little cold buttermilk before they go in. It helps them brown to that deep golden finish without any egg wash fuss.

🔥 Step 6: Bake Hot & Fast

Slide the sheet into the fully preheated oven and bake for 16–19 minutes, until the biscuits are dramatically tall and deep golden brown on top. The sides touching each other will be paler — that's fine, those are the soft bits you tear apart.

Brush the tops with melted butter the second they come out of the oven. Let them cool on the pan for 2–3 minutes, then serve while they're still warm and steaming.

Pro-Level Move: If the tops are browning too fast but the biscuits still look pale in the middle, tent loosely with foil for the last few minutes.

👩🍳 Squirrelly Girl Baker's Tips

🧈 1. Freeze your butter. Frozen-then-grated butter is the fastest route to flaky. It barely warms in your hands before it's already in the flour.

📏 2. One inch is not a suggestion. Most biscuits fail at the ruler stage. If you roll them thin, you get crackers with ambitions. Pat thick, cut straight, bake hot.

🚫 3. Never twist the cutter. One clean press, straight down. A twisted cut pinches the edges shut and your biscuits rise like a deflated balloon.

🤏 4. Touching biscuits rise taller. Place them snug, sides just kissing. They support each other and push upward. Give them space and they spread into thin, crispy-edged rounds — still good, just not sky-high.

🧪 5. No buttermilk? Fake it. Add 1 tablespoon of lemon juice or white vinegar to a scant ½ cup of whole milk and let it sit 5 minutes. Kefir or thin plain yogurt thinned with a splash of milk works too.

🧊 Make Them Ahead

These are best eaten warm within a day, but they keep well. Store cooled biscuits in an airtight container at room temperature for up to 2 days.

To freeze before baking (the best method): arrange the cut biscuits on a parchment-lined tray, freeze solid, then transfer to a zip-top bag for up to 3 months. Bake straight from frozen — just add 3–5 minutes to the bake time. Fresh biscuits on a whim, forever.

To freeze baked biscuits: wrap cooled biscuits tightly and freeze up to 3 months.

Reheat like this: split and toast them, or warm in a 350°F (175°C) oven for 5–8 minutes until the edges crisp back up. A cold biscuit is fine. A reheated one is almost like fresh.

🚨 Sourdough Biscuit Troubleshooting

My biscuits came out flat and dense.

Almost always one of three culprits: the butter was too warm going in, the dough was rolled too thin, or the cutter was twisted. Next batch: freeze the butter, pat to a full inch, press straight down. Old baking powder can also be guilty — check the date on the can.

They taste too tangy/sour.

Use fresher discard next time — discard that's been sitting for weeks carries more acid. The tang also mellows as the biscuits cool slightly, so give them 10 minutes before judging.

The bottoms are dark but the tops are pale.

Your oven has a hot bottom. Bake on the middle rack and slide an empty baking sheet on the rack below to deflect the direct heat. The buttermilk brush on top helps with browning too.

My dough was sticky and impossible to fold.

Warm kitchen, warm hands, or extra-wet discard. Chill the dough 10–15 minutes, add a light dusting of flour to the surface, and fold with a bench scraper instead of your fingers.

They spread instead of rising tall.

The butter melted into the flour before baking. Next time keep everything colder, work faster, and place the biscuits close together on the pan so they climb instead of spread.

❓ FAQ: Sourdough Buttermilk Biscuits

Can I use active starter instead of discard?

Yes — active starter works exactly the same here. The biscuits might be a touch puffier. Discard is the natural choice though: the rise comes from baking powder and soda, so the starter is there for flavor and tenderness, and discard was destined for this.

How do I get tall, flaky biscuits instead of flat ones?

Cold everything, fold the dough three times like a letter, cut to a full inch thick without twisting the cutter, and place the rounds so their sides touch. Each of those steps adds height — skip one and you'll notice.

Can I make these without buttermilk?

Yes. Add 1 tablespoon of lemon juice or white vinegar to a scant ½ cup of whole milk and let it sit 5 minutes until it looks slightly curdled. Plain kefir works too. Real buttermilk gives the best flavor, but the swap won't ruin your morning.

Why did my biscuits come out tough?

Overmixing and overhandling. The dough should look shaggy when you stop stirring, and the folding should be quick and gentle. If you kneaded it like bread dough, that explains the texture — treat it like it's fragile, because it is.

Can I make the dough ahead of time?

It's better to cut the biscuits first, then freeze the shaped biscuits before baking (up to 3 months, baked straight from frozen). The leavening works best when it goes into a hot oven fresh, so don't hold mixed dough in the fridge for days.

❤️ Happy Biscuit Morning!

Feed your starter.

Save the discard.

Keep that butter cold.

Fold like you mean it.

And prepare for biscuits that make everyone ask, "You made these yourself?"
