Chewy Sourdough Sugar Cookies
These chewy sourdough sugar cookies turn leftover starter discard into something far better than the plain sugar cookies you grew up with. They come out of the oven with a tender crumb, crisp edges, and a gentle tang that makes the sweetness taste more interesting.
The dough is simple to mix, easy to handle, and you can top them with a quick vanilla icing or a sprinkle of sugar. I reach for this recipe when I want a cookie that actually stays soft for days, not just hours.
What Makes These Cookies So Good
The discard brings a subtle tang that balances the sugar without screaming sour. It also adds a bit of extra moisture, so the centers stay soft even after the edges crisp up.
And unlike many cut-out cookies that turn stale by the next afternoon, these hold their texture surprisingly well. You can bake a batch on Saturday and still enjoy them on Tuesday, which makes them great for baking ahead of a holiday.
Ingredients
- 2 1/2 cups all-purpose flour: spooned and leveled, not scooped
- 1/2 teaspoon baking powder: for a little lift
- 1/2 teaspoon fine sea salt: brings the flavors into focus
- 1 cup unsalted butter, softened: let it sit at room temp for an hour
- 1 cup granulated sugar: plain white sugar works best here
- 1 large egg: cold is fine
- 2 teaspoons vanilla extract: the real stuff if you have it
- 1/2 cup sourdough discard (unfed, 100% hydration): straight from the fridge is okay
Variations and Swaps
- Citrus twist: swap the vanilla for 2 teaspoons finely grated lemon or orange zest and a drop of matching extract.
- Spiced version: add 1 teaspoon ground cinnamon and a pinch of nutmeg along with the flour.
- Chocolate icing: melt 2 ounces of chopped semisweet chocolate into the icing mix for a richer topping.
- Skip the icing: brush the unbaked cookies with a little milk and sprinkle with coarse sugar for a simpler finish.
A similar idea shows up in my sourdough snickerdoodles if you want a cinnamon-focused cookie.
How to Make Chewy Sourdough Sugar Cookies
Step 1: Cream the Butter and Sugar
In a large bowl, beat the 1 cup softened butter and 1 cup granulated sugar with an electric mixer on medium speed until light and fluffy, about 3 minutes. Scrape down the sides once or twice so everything incorporates evenly.
Add the egg, 2 teaspoons vanilla, and the 1/2 cup sourdough discard. Mix on low just until combined and the discard disappears into the batter. At this point the mixture will look a little curdled, and that is exactly how it should be.
Step 2: Add the Dry Ingredients
Whisk the 2 1/2 cups flour, 1/2 teaspoon baking powder, and 1/2 teaspoon salt together in a separate bowl. Add half of this dry mix to the butter mixture and mix on low until barely combined. Then add the rest and mix just until no dry streaks remain.
Gently fold by hand a few times with a spatula to make sure there are no pockets of flour hiding at the bottom. Stop the second it comes together, overworking the dough now will make the cookies tough.
Step 3: Chill the Dough
Turn the dough out onto a piece of plastic wrap, shape it into a flat disc, and wrap it tightly. Refrigerate for at least 2 hours, or up to 2 days if you are planning ahead.
This chill is nonnegotiable. It firms up the butter so the cookies keep their shape in the oven and it gives the flour time to hydrate, which makes the centers chewy instead of cakey.
Step 4: Roll and Cut the Shapes
Place the chilled dough between two large sheets of parchment paper and roll it out to a 1/4 inch thickness. The parchment keeps you from adding extra flour, so the cookies stay tender.
Peel off the top sheet and cut out shapes with a floured cookie cutter, then transfer the cutouts to a parchment-lined baking sheet. Gather the scraps, press them together gently, re-roll, and cut again. If the dough starts to feel sticky or warm, slide the whole thing onto a baking sheet and pop it in the fridge for 10 minutes.
Step 5: Bake Until Golden
Heat your oven to 350°F (175°C) if it is not already warm. Bake the cookies on the prepared sheets for 9 to 11 minutes, rotating the pan halfway through. You are looking for edges that are just starting to turn a faint golden brown while the centers still look pale and slightly puffed.
Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely before you ice them. They will firm up as they cool but stay soft in the middle.
Step 6: Ice the Cookies
In a small bowl, stir together 1 cup powdered sugar, 1/2 teaspoon vanilla, and 2 to 3 tablespoons of milk until smooth and thick but able to be drizzled from a spoon. If it runs too thin, add a little more sugar; too thick, add a tiny splash more milk.
Spread or drizzle the icing over the cooled cookies and top with sprinkles if you like. Once the icing sets, the cookies are ready to share and look just as cheerful as they taste.
Tips for Better Sourdough Sugar Cookies
- Weigh your flour if you have a scale. 2 1/2 cups should be about 312 grams, and even a small scoop extra can turn a soft cookie dry.
- Roll the dough between two sheets of parchment paper instead of flouring the counter. This keeps the cookies tender and avoids adding extra gluten.
- If the dough gets sticky while you are cutting shapes, slide the whole thing onto a baking sheet and refrigerate for 10 minutes before continuing.
- Let the cookies cool completely on the rack before icing, or the icing will melt right off and pool at the edges.
Keeping the Cookies Fresh
Refrigerate: Store cooled, uniced cookies in an airtight container at room temperature for up to 5 days. If iced, let the icing set fully, then layer them with parchment paper so they do not stick.
Freeze baked cookies: Freeze the plain cookies for up to 3 months. Thaw at room temperature, then ice just before serving.
Freeze the dough: Wrap the disc of dough tightly and freeze for up to 3 months. Thaw overnight in the fridge, then roll and bake as usual.
Frequently Asked Questions
Can I use active sourdough starter instead of discard?
Yes. The cookies will turn out nearly identical, though an active starter can bring a slightly stronger tang.
Do I absolutely need to chill the dough?
Yes. Without chilling, the cookies spread too much in the oven and lose their crisp edges. The 2 hours is worth it.
Why did my cookies turn out tough?
The most common reason is overmixing once the flour goes in, or accidentally packing in too much flour. Mix just until combined and spoon the flour into your cup lightly.
Can I ice the cookies while they are still warm?
No, the icing will melt and slide right off. Cool the cookies completely on a rack before adding any glaze.
