Soft Sourdough Sugar Cookies (No Cutouts!)

Let’s be honest, most sugar cookies are a bit of a letdown. They’re either too crunchy, too dry, or require a rolling pin and two hours of chilling before you can even think about baking. But these? These are different. As a former micro-bakery owner turned blogger, I set out to create the absolute best, NOT dry sugar cookie. I wanted one that stands tall, stays thick and chewy in the center, and uses that sourdough discard sitting in your fridge to add a perfectly subtle tang. This recipe is everything I hoped it would be. These delightfully balanced, soft, and chewy sourdough sugar cookies come together in under 30 minutes with no rolling, no chilling, and no cutouts! Whether you’re topping them with my dye-free glaze for a holiday, or grabbing one warm off the sheet, these are about to become a permanent favorite in your sourdough rotation.

Essentials for the Perfect Sourdough Cookie

• Digital Kitchen Scale: In my kitchen, a digital scale is a non-negotiable! I have had this exact digital scale for years, and it has never failed me. Measuring by weight is the only way to guarantee a perfect bake every time. Since flour and sourdough starter are so difficult to measure accurately by volume, a scale ensures you don’t accidentally end up with a dry cookie or a flat puddle on your baking sheet!
• Stand Mixer: A quality stand mixer is a total game changer for sourdough cookie dough. This recipe relies on a thorough “creaming” of the butter and sugars to get that signature height. A mixer helps you achieve that aerated, fluffy base without over-working the flour, which is the secret to a tender, melt-in-your-mouth crumb.
• Large Cookie Scoop: Most of my sourdough cookie recipes are designed for jumbo, bakery-style cookies. Using a large cookie scoop (about 3 tablespoons) ensures that every cookie is uniform. This isn’t just for looks either, it ensures they all bake evenly so you get the perfect edges and a soft, thick center every single time!

Ingredients

• 1 cup light brown sugar, packed (220g): Make sure you pack it tight! The molasses in the brown sugar is the secret to a chewy, fudgy center rather than a dry, crumbly one.
• 2 tbsp granulated sugar (25g): A touch of white sugar helps balance the moisture and gives the edges that slightly crisp, classic sugar cookie exterior.
• ½ cup salted butter, softened (113g): You’re looking for “dent soft” butter, meaning it should indent easily when pressed but still offer some resistance. It shouldn’t be greasy or shiny. Depending on your kitchen’s temperature, this usually takes 30–60 minutes of sitting out to reach dent softness. If using unsalted butter, add an extra ¼ tsp of salt to the dough.
• ½ cup sourdough starter, active or discard, stirred down (150g): You can use either active starter or discard here! Just make sure to stir it down before measuring by volume, or better yet, measure by weight for total accuracy.
• 2 large egg yolks (40g): We’re using only the yolks to keep these cookies rich and chewy. While room temperature yolks are ideal, cold yolks work just fine in this recipe.
• 2 tsp vanilla extract (10g): Pure vanilla extract is best! It provides a deep flavor that imitation versions simply can’t match, and it ensures that you avoid unnecessary additives that are often found in imitation extracts.
• ½ tsp salt (3g): I prefer sea salt for a clean flavor profile. Iodized table salt can sometimes add a subtle metallic tang that we want to avoid.
• 1½ cups all-purpose flour, scooped directly from bag, not spooned and leveled (235g): Flour is notoriously difficult to measure by volume because it settles. I designed this recipe specifically to be scooped directly from the bag. Pro Tip: For the absolute best results and a consistently accurate texture, I highly recommend measuring your flour by weight.
• 1 tsp baking soda (6g): Make sure you are using baking soda, NOT baking powder. They are not interchangeable, and they react differently with the sourdough acidity. Baking soda is what gives us that perfect rise and soft texture.
• Finishing Options: For a crunchy, glistening exterior, roll your dough scoops in ½ cup of turbinado sugar or granulated sugar before baking. Or for an icing glaze topping, try my Simple Cookie Glaze Recipe, which includes my dye-free color guide!

How to Make Soft Sourdough Sugar Cookies

Preheat Oven & Prep: Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.

Cream the Butter & Sugar: Beat the brown sugar, granulated sugar, and softened butter together using a stand mixer or handheld electric mixer. You are looking for more than just a mix here; you want the texture to change. It should look creamy, uniform, and slightly aerated. If you still see chunks of butter, keep mixing!

Add the Wet Ingredients: Add your sourdough starter, egg yolks, vanilla extract, and salt. Beat until it becomes smooth and slightly frothy. Tip: Scrape down the sides of the bowl with a spatula to ensure the starter is fully incorporated; you shouldn’t see any streaks or chunks by the end of this step.

Incorporate the Dry Ingredients: Add your flour and sprinkle the baking soda on top. Turn your mixer to low speed, and stir until just combined. Critical Step: Stop mixing while you still see a few tiny streaks of flour. If you over-mix here, you’ll over-develop the gluten, and your cookies will be tough rather than soft and chewy.

Scoop: Use a large cookie scoop to place 6 generous portions (3 tbsp each) onto your prepared baking sheet. Ensure even spacing between each to allow for slight spreading.

Optional: For extra crunch, roll each scoop in turbinado or granulated sugar before baking. This recipe makes 12 total cookies.

Bake: Bake for 12–16 minutes, rotating the pan halfway through baking. You’ll know they are done when the edges look slightly crisp, but the centers look mostly set while still appearing soft. They will finish setting as they cool!

Cool On Baking Sheet: Let the cookies sit on the hot baking sheet for right around 7 minutes before transferring them to a cooling rack. This is a crucial step for ensuring that the cookies set up completely. If you try to move them too soon, they will fall apart. Optionally add icing or glaze once cooled.

Storage Tips

Once completely cool, you can store cookies in an airtight container or bag for up to 5 days at room temperature.

Pro Tip: To keep them soft for days, place a slice of bread in the container with the cookies. The cookies will absorb moisture from the bread (the bread will eventually become rock hard!), keeping your cookies soft and chewy for longer.

Substitutions & Variations

• Dark Brown Sugar: You can substitute dark brown sugar for light brown sugar in a pinch. It will result in a slightly deeper, more molasses-forward flavor and a darker golden color, but the texture will remain perfectly chewy.
• Unsalted Butter: If using unsalted butter, simply add an additional ¼ teaspoon of salt to the dough to balance the flavors.
• Active Sourdough Starter: While discard is common for cookies, active sourdough starter works beautifully! Just ensure you stir it down before measuring by volume to get an accurate amount.

Can I freeze sourdough sugar cookie dough?

Absolutely! For best results, follow this flash-freezing method:

1. Scoop: Portion the dough into balls and place them on a parchment-lined baking sheet. They can be close together, but make sure they are not touching.
2. Flash Freeze: Place the sheet in the freezer for about 1 hour, or until the dough balls are firm to the touch.
3. Store: Transfer the frozen dough balls into a gallon freezer bag. They can be stored in the freezer for up to 3 months!

Pro Tip: Double the recipe to intentionally freeze an extra batch! This provides you with a ready-to-bake sourdough cookie dough for when that sweet tooth hits. You can even bake just a few at a time for a quick, no-prep dessert.

Tips For Baking From Frozen:

• Add Time: Add 2-4 minutes to the specified baking time.
• Thaw Partially: Alternatively, allow dough to sit at room temperature for 30-60 minutes before baking. This helps achieve a texture and baking time nearly identical to a fresh batch of dough.

How to Make Long-Fermented Sourdough Sugar Cookies

If you want to maximize the flavor and gut-health benefits of your sourdough, you can long-ferment this dough in the fridge. Follow these simple steps:

1. Prepare: Follow the recipe directions to mix the dough.
2. Ferment: Cover the bowl tightly with plastic wrap or transfer the dough to an airtight container. Refrigerate for 1-3 days.
   
   • Note: While the health benefits increase the longer the dough ferments, the tangy sourdough flavor will also intensify. This is especially noticeable with sugar cookies, as the simple flavor profile won’t “mask” the tang as easily as a chocolate chip or spice cookie might.
3. Bake: Dough temperature significantly affects the final texture of these cookies. Choose your preferred method:
   
   • For Chewier Cookies (preferred): Remove the dough from the fridge about 1 hour before baking to let it reach room temperature. This results in a thick, chewy texture nearly identical to a freshly made batch.
   • For Cake-Like Cookies: If you’re in a hurry, you can bake the dough straight from the fridge. Because the cold butter won’t melt as quickly, the cookies won’t spread as much, resulting in a puffier, more cake-like consistency. Only use this method if you’re in a rush, as it may result in unevenly baked cookies that are underdone in the center or overdone on the edges.
