Sourdough Discard Snickerdoodles Ingredients
Cookie Dough
- 115 g unsalted butter (about 1/2 cup, browned and slightly cooled)
- 150 g granulated sugar (about 3/4 cup)
- 50 g light brown sugar, packed (about 1/4 cup)
- 120 g sourdough discard (about 1/2 cup, unfed is perfect)
- 1 large egg, at room temperature
- 2 tsp vanilla extract
- 240 g all-purpose flour (about 2 cups, spooned and leveled)
- 2 tsp cream of tartar
- 1/2 tsp baking soda
- 1/2 tsp fine sea salt
- 1 tsp ground cinnamon
Cinnamon Sugar Coating
- 50 g granulated sugar (about 1/4 cup)
- 1 tbsp ground cinnamon
🥣 Step 1: Brown the Butter
Melt the butter in a light-colored saucepan over medium heat, swirling the pan now and then. It will foam, then crackle, then the milk solids at the bottom will turn golden brown and smell like toasted hazelnuts. That takes about 5 minutes — and the moment it smells nutty, pull it off the heat so it doesn't tip over into burnt.
Pour the brown butter, browned bits and all, into a large mixing bowl and let it cool for about 10 minutes, until it's warm rather than hot. Those browned bits are pure flavor — do not strain them out.
Beginner Tip: A light-colored pan is your best friend here. In a dark pan you can't see the color change, and brown butter goes from perfect to burnt in about thirty seconds.
🥣 Step 2: Mix the Wet Ingredients
Whisk the granulated sugar and brown sugar into the cooled brown butter until smooth and slightly thickened, about a minute. Beat in the sourdough discard, egg, and vanilla until everything is fully combined and glossy.
Your discard can come straight from the fridge — cold discard works fine here, since the warm butter brings the bowl up to temperature. Unfed, tangy, a few days old? Perfect.
Pro-Level Move: If your discard is very runny, give it a quick stir first so it measures evenly, and don't be tempted to add extra — the balance of wet to dry is what keeps these cookies thick instead of flat.
🥣 Step 3: Mix the Dry Ingredients
In a separate bowl, whisk together the flour, cream of tartar, baking soda, salt, and cinnamon. The cream of tartar is non-negotiable — it's what gives snickerdoodles their signature tang and their soft, pillowy chew.
Add the dry ingredients to the wet bowl in two batches, stirring with a spatula just until no dry flour remains. Stop as soon as it comes together. Overmixing develops gluten and turns soft cookies tough, and nobody asked for a tough snickerdoodle.
Beginner Tip: The dough will look soft and slightly sticky. That's correct. Resist the urge to keep adding flour — the chill in the next step firms it right up.
🥣 Step 4: Chill and Roll in Cinnamon Sugar
Cover the bowl and chill the dough for 30 minutes. Meanwhile, stir together the cinnamon sugar coating in a small shallow bowl.
Scoop the chilled dough into balls of about 2 tablespoons each — a cookie scoop makes this fast and keeps the cookies even — and roll each ball generously in the cinnamon sugar until fully coated. Place them about 2 inches apart on parchment-lined baking sheets.
Pro-Level Move: Roll twice for an extra-thick crackled crust: once before chilling, and again right before baking. The double coat is what gives you those dramatic crinkles.
🥣 Step 5: Bake Until Just Set
Bake in a preheated 190°C (375°F) oven for 10–12 minutes, until the edges look set and lightly golden but the centers still look slightly soft and puffy. They will firm up as they cool — that's the whole secret to a chewy center.
Pull them at the first sign of golden edges, even if the middles look a touch underdone. An extra two minutes in the oven is the difference between soft-and-chewy and dry-and-crumbly, and there's no going back.
Beginner Tip: Bake one test cookie first if you're nervous. It tells you exactly how your oven behaves, and you get to eat the evidence.
🥣 Step 6: Cool (Briefly) and Devour
Let the cookies rest on the baking sheet for 5 minutes — they finish setting up in that window — then transfer them to a wire rack to cool completely. Or don't. Warm snickerdoodles with a glass of milk have ended many a bad day on a better note.
Store cooled cookies in an airtight container for up to 5 days, with a slice of bread tucked in if you want to keep them extra soft.
👩🍳 Squirrelly Girl Baker's Tips
1. 🧈 Brown butter is worth it. It takes five extra minutes and adds a toasty depth that plain melted butter just can't fake.
2. 🥄 Spoon and level your flour. Scooping straight from the bag packs in extra flour and dries the cookies out. Spoon it in, level it off.
3. ❄️ Don't skip the chill. Thirty minutes keeps the cookies thick and stops them from spreading into thin crisps.
4. 🍪 Size matters. Keep the balls even and you'll get even baking — no tray where half the cookies are perfect and half are overdone.
5. ⏱️ Underbake on purpose. Set edges plus soft centers out of the oven equals perfect chewy cookies once cooled.
6. 🫙 The bread trick works. A slice of plain bread in the cookie container keeps snickerdoodles soft for days — the cookies steal its moisture.
🧊 Make It Ahead
The dough keeps in the fridge, tightly covered, for up to 3 days — and honestly, a day of resting deepens the flavor. Scoop and roll the chilled dough straight from the fridge, adding a minute or two to the bake time.
To freeze, roll the dough balls in cinnamon sugar, freeze them solid on a tray, then bag them up with parchment between layers. They keep for up to 3 months; bake from frozen, adding 2–3 minutes. Baked cookies freeze well too — cool completely, layer with parchment, and thaw for about 30 minutes.
🚨 Sourdough Discard Snickerdoodles Troubleshooting
My cookies spread flat. What happened?
Usually warm dough or butter that was too hot when mixed. Chill the full 30 minutes, and if your kitchen runs warm, chill the scooped balls on the tray for 10 minutes before baking.
Why aren't my cookies crackling?
The crackle comes from the cinnamon sugar crust plus the cream of tartar lift. A generous double roll helps, and so does not overmixing — overworked dough bakes smooth instead of crinkled.
My cookies came out dry and cakey. Help?
Almost always too much flour or too long in the oven. Spoon and level your flour, and pull the cookies while the centers still look soft. They set as they cool.
Can I use active starter instead of discard?
Yes — active starter works the same way here, since there's no fermentation step. The cookies may taste slightly less tangy.
My dough is too sticky to roll. What do I do?
Chill it longer — up to an hour if needed — and wet your hands lightly before scooping. The cinnamon sugar coating also makes sticky dough much easier to handle.
Can I make these without cream of tartar?
You can swap in 1 teaspoon of lemon juice or white vinegar, but the classic snickerdoodle tang and chew really come from cream of tartar. If you bake these often, it's worth keeping some on hand.
⚠️ Baker's Warning
Fair warning: once your household realizes discard turns into warm cinnamon-sugar cookies, nobody will ever let you throw discard away again. You have just volunteered as the person who always has cookies. There is no going back, and honestly, why would you want to?

❓ FAQ: Sourdough Discard Snickerdoodles
Do sourdough discard snickerdoodles taste sour?
Not really — just a gentle background tang that makes the cinnamon taste brighter. Very old, sharp discard gives a bit more tang, but the brown sugar and cinnamon keep it balanced.
Can I skip browning the butter?
Yes — just use melted butter, cooled slightly, and the cookies will still be delicious. You'll lose some of the toasty depth, but the cinnamon sugar and tang carry the flavor on their own.
How long do sourdough discard snickerdoodles stay soft?
About 5 days in an airtight container at room temperature, especially with the bread-slice trick. After that they firm up but still taste great dunked in milk.
Can I double this recipe?
Absolutely — it doubles cleanly. Use a full cup of discard and bake in batches, rotating trays halfway through.
Do I need to feed my starter first?
No. This recipe is designed for unfed discard, straight from the fridge. That's the whole point — turning what you'd otherwise toss into something worth baking.
Why do snickerdoodles need cream of tartar?
Cream of tartar gives snickerdoodles their signature tang and keeps the crumb soft and chewy instead of crisp. It also reacts with the baking soda for the perfect amount of lift.
