Kitchen Tools You’ll Need
- Mixing bowl
- Whisk
- Measuring cups and spoons
- Baking sheet
- Parchment paper (optional)
- Cookie scoop or spoon
Ingredients
- 2.6 oz unfed sourdough starter (adds moisture and slight tang)
- 1 tsp vanilla extract (enhances the overall flavor)
- 10 grams baking powder (provides leavening for a soft texture)
- 3.5 oz cane sugar (for coating, adds sweetness and a slight crunch)
- 8 oz unsalted butter (softened, adds richness and moisture)
- 8.8 oz cane sugar (sweetness and helps create a tender cookie)
- 10.6 oz all-purpose flour (structure and absorbs moisture)
- 6 grams salt (balances sweetness and enhances flavors)
- 2 egg yolks (richness and helps bind the ingredients)

How to Make Soft Sourdough Discard Sugar Cookies
Step 1. Begin by mixing the softened unsalted butter and 8.8 oz of cane sugar in a bowl until the texture is light and fluffy. This process will incorporate air into the mixture, making for softer cookies. Combine them thoroughly; it’s ready when the butter and sugar are well blended and smooth in appearance.
Step 2. Next, add the unfed sourdough starter, egg yolks, vanilla extract, and a pinch of salt to the butter-sugar mixture. Stir until the mixture is completely combined. This step is essential as it ensures that the ingredients intermingle well, resulting in a cohesive dough without any visible butter or sugar lumps.
Step 3. In a separate bowl, whisk together the all-purpose flour and baking powder. Once fully mixed, gradually incorporate the dry ingredients into the wet mixture. Stir just until combined; overmixing can lead to tougher cookies. The dough should begin to come together without any dry flour remaining.
Step 4. Cover the mixing bowl with plastic wrap or a clean towel and let the dough rest in the refrigerator for at least 30 minutes. Chilling the dough will help firm it up, preventing the cookies from spreading too much during baking and helping to develop the flavor.
Step 5. After chilling, preheat your oven. While waiting, prepare a baking sheet lined with parchment paper if desired. This will help prevent sticking and make cleanup easier. Use a cookie scoop or spoon to portion out the dough. It’s best to work with slightly rounded balls to ensure even baking.
Step 6. Roll each dough ball in the 3.5 oz of cane sugar before placing them on the prepared baking sheet. The sugar coating adds a nice exterior crunch and sweetness. Arrange them a couple of inches apart, since they will expand while baking.
Step 7. Bake the cookies in the preheated oven until the edges just take on a golden hue, while the center remains soft and slightly puffy. It’s important not to overbake, as this will change the intended soft texture. The cookies will set up further as they cool on the baking sheet.
Step 8. Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack. This will help them firm up a bit while maintaining their tender center. Let them cool completely before serving to enjoy their optimal texture and flavor.

Pro Tips for Best Results
- Ensure your butter is softened to room temperature for easy mixing, creating a better texture in the final cookies.
- Allow the dough to chill sufficiently in the refrigerator to control spread while baking.
- For an even texture, try to scoop the dough consistently so each cookie bakes evenly.
- Keep a close eye on the cookies as they bake; removing them just as they turn slightly golden will maintain their soft center.
- Store the cookies in an airtight container to keep them fresh longer.
Common Mistakes to Avoid
- Not softening the butter: Using cold butter can lead to dense cookies. Creaming softened butter with sugar is key for a lighter texture.
- Overmixing the dough: Overworking the dough can make the cookies tough. Mix just until the ingredients are combined for optimal softness.
- Skipping the chilling time: Not chilling the dough can result in spreading cookies. Chilling firms up the fat, helping to retain shape during baking.
- Incorrect oven temperature: Baking at too high of a temperature can burn the edges before the center is fully set. It’s important to preheat and check your oven’s accuracy.
- Not measuring flour correctly: Packing down flour can lead to more in the dough than needed, affecting texture. Use the spoon and level method for measuring.
- Baking on an ungreased sheet: If not using parchment paper, grease your baking sheet lightly to prevent the cookies from sticking.
Variations & Substitutions
You can experiment with different extracts, like almond or lemon, for a unique flavor twist. Consider adding chocolate chips or nuts for extra texture and richness. Swapping half of the all-purpose flour for whole wheat flour can give a nuttier flavor while still keeping the cookie structure.
Storage & Reheating
Store these cookies at room temperature in an airtight container for up to a week. For longer storage, they can be refrigerated, but allowed to sit at room temperature for a softer texture when ready to eat. If you wish to freeze them, place the cookies in a single layer in a freezer-safe bag for up to three months. To enjoy frozen cookies, allow them to thaw at room temperature or gently warm them in the oven to restore their soft texture.
Frequently Asked Questions
Can I make this recipe ahead of time?
Yes, you can prepare the dough in advance and store it in the refrigerator for up to 24 hours before baking. Just allow it to sit at room temperature for a few minutes before scooping and rolling in sugar.
How long does it last in the fridge?
These cookies can last about a week in the fridge if stored properly in an airtight container. They may dry out if left uncovered, so seal them well.
Can I freeze this recipe?
Certainly! You can freeze the cookie dough or the baked cookies. For best results, freeze baked cookies in a single layer in an airtight container. Dough can be frozen in portions and baked straight from frozen, just add a few minutes to the baking time.
What can I substitute for one ingredient?
If you don’t have unsalted butter, you can use salted butter; just be cautious when adding additional salt to the recipe. If you’re looking for an egg yolk substitute, you can use applesauce or a chia egg for a similar binding effect.
Why didn’t my recipe turn out as expected?
There are a few reasons this might happen—common issues include using cold ingredients, not measuring flour correctly, or baking at the wrong temperature. Ensure you follow each step carefully for the best results.
