Ingredients
Instructions
1. Cream the Butter and Sugars: In a large mixing bowl, using an electric mixer, beat the softened butter, granulated sugar, and brown sugar together until the mixture is light, fluffy, and pale in color. This usually takes about 2-3 minutes. Scrape down the sides of the bowl as needed to ensure everything is well combined.
2. Add Wet Ingredients: Beat in the egg and vanilla extract until fully incorporated. Then, add the sourdough starter discard and mix on low speed until just combined. The mixture might look a little curdled at this stage, but don’t worry, it will come together.
3. Combine Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and salt. Make sure there are no lumps in the flour mixture.
4. Gradually Add Dry to Wet: Slowly add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix the dough once the flour is added, as this can lead to tough cookies. Stop mixing as soon as no dry streaks of flour remain.
5. Fold in the Mix-ins: Gently fold in the chocolate chips and rolled oats using a spatula or a wooden spoon until they are evenly distributed throughout the dough.
6. Prepare for Baking: Preheat your oven to 375 F (190 C). Line a baking sheet with parchment paper. Drop rounded tablespoons of dough onto the prepared baking sheet, leaving about 2 inches between each cookie. You can use a cookie scoop for uniform size.
7. Bake Until Golden: Bake for 10-12 minutes, or until the edges are lightly golden brown and the centers are still slightly soft. The cookies will continue to set as they cool.
8. Cool and Enjoy: Remove the baking sheet from the oven and let the cookies cool on the sheet for 5 minutes before transferring them to a wire rack to cool completely. This helps them firm up without breaking.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you start baking makes the whole process smoother and more enjoyable. You likely have most of these items in your pantry already, making these cookies a convenient choice for a spontaneous baking session. The star ingredient, of course, is the sourdough discard, which adds that special touch without requiring any complicated steps.
INGREDIENTS:

- 1/2 cup (1 stick) unsalted butter, softened
- 1/2 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 cup unfed sourdough starter discard (100% hydration)
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 1/2 cup rolled oats (quick or old-fashioned)
For the butter, if you only have salted butter on hand, you can use it and simply omit the added salt in the recipe. Just make sure it’s softened to room temperature for easy creaming. When it comes to sugars, using both granulated and brown sugar gives these cookies their perfect chewy texture and depth of flavor. If you prefer a slightly less sweet cookie, you can reduce the sugar by a tablespoon or two, but don’t cut too much as it affects the texture. The sourdough discard should be unfed and at room temperature; it doesn’t need to be active or bubbly for this recipe. Any brand of all-purpose flour will work well here. For the chocolate chips, feel free to use milk chocolate, dark chocolate, or even a mix of different types to suit your preference. The rolled oats add a lovely chewiness and heartiness to the cookies, distinguishing them from a standard chocolate chip cookie.
Time Needed From Start To Finish
This recipe is designed for efficiency, delivering delicious results without a huge time commitment.
- Preparation Time: 15 minutes
- Baking Time: 10-12 minutes per batch
- Total Time: Approximately 30-35 minutes (including one batch bake time)
The prep time is quite quick since there’s no chilling required for the dough, which is a huge bonus when you want cookies fast. The baking time is standard for cookies, and you’ll likely need to bake in two batches depending on the size of your baking sheets.

Easy Variations And Serving Ideas That Fit Real Life
These sourdough monster cookies are incredibly versatile and can be adapted to suit different tastes and occasions. For a fun twist, consider adding a handful of chopped peanuts or pretzels along with the chocolate chips for an extra layer of crunch and salty-sweet flavor. If you’re a fan of white chocolate, swap out half of the semi-sweet chocolate chips for white chocolate chips. You could also include a sprinkle of flaky sea salt on top of the cookies right after they come out of the oven to enhance the chocolate flavor.
These cookies are fantastic on their own as an everyday snack or a simple dessert. For a special treat, serve them warm with a scoop of vanilla ice cream, allowing the ice cream to melt slightly into the soft cookie. They’re also perfect for lunchboxes, picnics, or as a comforting treat with a glass of cold milk or a cup of coffee. If you’re hosting a casual get-together, arrange them on a platter with other small desserts. For a kid-friendly option, let them help press a few extra chocolate chips onto the top of the dough balls before baking – they love to personalize their treats!
Common Slip-Ups And How To Avoid Them
Even simple recipes can have a few common pitfalls. Knowing what to watch out for can help ensure your sourdough monster cookies turn out perfectly every time.
- Overmixing the Dough: Once you add the flour, it’s crucial to mix only until just combined. Overmixing develops the gluten in the flour, leading to tough, dense cookies instead of the desired chewy texture. Mix on low speed and stop as soon as you no longer see dry streaks of flour.
- Using Cold Butter: Softened, room-temperature butter is essential for proper creaming with the sugars. If your butter is too cold, it won’t cream properly, resulting in a dense cookie. If it’s too warm or melted, the cookies might spread too much. Let your butter sit on the counter for about 30-60 minutes before you start.
- Overbaking the Cookies: These cookies are best when they’re slightly underbaked in the center, as they continue to cook on the hot baking sheet after coming out of the oven. Look for lightly golden edges and centers that still look a little soft. If you bake them until they’re firm and dark all over, they’ll be dry and crumbly.
- Not Using Parchment Paper: Parchment paper prevents sticking and helps the cookies bake evenly. Without it, your cookies might stick to the pan or brown unevenly. If you don’t have parchment paper, a silicone baking mat is a good alternative.
- Incorrect Sourdough Discard Hydration: This recipe assumes a 100% hydration sourdough discard (equal parts flour and water by weight). If your discard is significantly different, it might affect the dough consistency. For best results, stick to a 100% hydration discard, which is the most common type.
How To Store It And Make It Ahead Without Ruining Texture
Proper storage is key to keeping your sourdough monster cookies fresh and delicious, and they’re also great for making ahead.
Once completely cooled, store the cookies in an airtight container at room temperature for up to 3-4 days. To maintain their chewiness, you can place a slice
