Tender sourdough-discard sugar cookies with a sparkling coating, vanilla flavor and a subtle cultured tang.
The important detail in this recipe is the way the dough is shaped and finished. Scoop generous tablespoon portions, about 29 g each. Roll gently in the coating sugar and arrange 2 inches apart on parchment. Bake immediately on cool pans.
Before mixing, measure the flour without packing it and prepare the pans. This dough assumes 100% hydration discard: equal water and flour by weight. A stiff starter or a very watery starter changes the moisture; use the specified consistency.
Watch the first tray closely near the end of the baking range. Let the crumb set on the pan before lifting the cookies, then store only after they have cooled.
Sourdough Sugar Cookies
Per tray: 13–15 minutes · About 3 trays, 12 cookies per 13 × 18-inch half-sheet pan.
Plan 95 minutes: 25 hands-on, 0 required chilling, 45 for all trays baked sequentially, and 25 cooling including pan rest. Preheat during preparation or the final chilling minutes. Ingredient warm-up and extra trays add time.

Ingredients
Scale ingredients and US equivalents, including eggs; weigh beaten egg for fractional batches. Keep piece size, thickness, oven temperature and baking time per tray unchanged. Extra trays increase whole-batch time.

Instructions
Mixing
- Make the doughWhisk flour and leaveners. Beat butter, cream cheese, sugar and salt until smooth. Mix in yolks and extracts, then the starter discard. Add the dry mixture just until no flour pockets remain.
Thermal management
- Manage the doughNo scheduled chilling is needed. Start with butter that indents under a finger but remains cool, not greasy; keep dough away from a warm oven.
Shaping
- Shape evenlyScoop generous tablespoon portions, about 29 g each. Roll gently in the coating sugar and arrange 2 inches apart on parchment. Bake immediately on cool pans.
Baking
- Bake one tray at a timePreheat to 350°F (175°C). Bake on the center rack for 13–15 minutes. Edges should be set and only lightly colored; centers must lose their wet sheen. Use cool pans for subsequent trays.
Cooling
- Let the crumb setCool completely on the baking sheet, about 25 minutes including pan rest. The delicate centers firm as they cool; avoid moving them straight from the oven.
Chef’s Science & Pro Tips
Match starter hydration
This dough assumes 100% hydration discard: equal water and flour by weight. A stiff starter or a very watery starter changes the moisture; use the specified consistency.
Keep the portion consistent
Scoop generous tablespoon portions, about 29 g each. Roll gently in the coating sugar and arrange 2 inches apart on parchment. Bake immediately on cool pans. Different thicknesses need different baking times; bake comparable pieces together.
Use a consistent starter
Use unfed discard at 100% hydration, equal flour and water by weight. There is no fermentation step; powder and soda provide the lift. A much thicker or wetter starter changes the dough balance.
Storage & Make-Ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 3–4 days | Cool completely and seal in an airtight container. Keep unfrosted cookies separate from moist or strongly flavored treats. |
| Refrigeration | Raw dough: up to 2 days | Cover raw dough tightly. Refrigerating plain baked cookies is unnecessary and can dry them; let chilled dough become workable before shaping. |
| Freeze raw | Up to 2 months | Freeze portioned dough balls on a tray, then seal in a freezer bag. Bake from frozen, allowing extra time and checking for a set center. |
| Freeze baked | Up to 2 months | Freeze fully cooled, plain cookies in a sealed container with parchment between layers. |
| Restore | 30–60 minutes | Thaw baked cookies in their closed container at room temperature. For a freshly warmed plain cookie, use a 300°F oven for 2–3 minutes; cool briefly before serving. |
Notes
- Use the gram weights for the most consistent dough. Small leavener weights are approximate; measure teaspoons carefully. Egg weights exclude shells. Oven temperatures refer to a conventional oven.

Frequently Asked Questions
A few helpful answers before you bake.
What texture should these cookies have?
Tender sourdough-discard sugar cookies with a sparkling coating, vanilla flavor and a subtle cultured tang. Judge the final texture after cooling, not while the centers are warm.
Can I use a stiff starter?
This dough assumes 100% hydration discard: equal water and flour by weight. A stiff starter or a very watery starter changes the moisture; use the specified consistency.
Does the starter need to be active?
Use unfed discard at 100% hydration, equal flour and water by weight. There is no fermentation step; powder and soda provide the lift. A much thicker or wetter starter changes the dough balance.
