Step‑by‑Step Instructions for Sourdough Chocolate Peanut Butter Swirl Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This crucial step ensures your Sourdough Chocolate Peanut Butter Swirl Cookies bake evenly and develop a lovely texture. While the oven heats up, prepare your baking sheets by lining them with parchment paper, which will help prevent the cookies from sticking.
Step 2: Cream the Butter and Sugars
In a stand mixer fitted with a paddle attachment, combine softened unsalted butter, cane sugar, and brown sugar. Beat on medium speed for 2–3 minutes until the mixture is light and fluffy, achieving a pale, airy texture. This step is key for ensuring your cookies have a tender crumb, so don’t rush through it!
Step 3: Incorporate the Wet Ingredients
Add the eggs one at a time to the butter-sugar mixture, blending until thoroughly combined after each addition. Then, mix in the vanilla extract and sourdough discard, ensuring everything is well incorporated. The sourdough discard adds a unique flavor and tang that will elevate these cookies, making them truly special.
Step 4: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, unsweetened cocoa powder, salt, and baking soda until well combined. Slowly add this mixture to the wet ingredients, mixing on low speed until just combined. You should see a thick, chocolatey dough forming, which means you’re on the right track!
Step 5: Fold in the Chocolate Chips
Gently fold the chocolate chips into the cookie dough using a spatula. Be careful not to overmix; you want the chocolate chips evenly distributed but not the dough overworked. The additional chocolate will enhance the cookie’s richness and create delightful melty pockets of goodness in your Sourdough Chocolate Peanut Butter Swirl Cookies.
Step 6: Swirl in the Peanut Butter
Now, pour the runny peanut butter over the cookie dough. Using a spatula, gently fold the peanut butter into the dough to create beautiful swirls, being cautious not to overmix. This step will give your cookies their signature sweet and salty flavor, so embrace the artistry of the swirls!
Step 7: Scoop and Bake
Using a cookie scoop or tablespoon, drop generous amounts of cookie dough onto the lined baking sheets, leaving space between each scoop. Sprinkle a little cane sugar over the tops for an extra touch of sweetness and slight crunch. Bake in the preheated oven for 8–10 minutes, until the tops look set and lose their shine.
Step 8: Cool the Cookies
Once baked, carefully transfer the cookies to a wire rack to cool before indulging. Allow them to rest for at least 5 minutes on the baking sheets before moving them. This helps the cookies firm up, ensuring the perfect chewy texture for your Sourdough Chocolate Peanut Butter Swirl Cookies.

Make Ahead Options
These Sourdough Chocolate Peanut Butter Swirl Cookies are perfect for busy home cooks looking to save time during the week! You can prepare the cookie dough up to 24 hours in advance. Simply mix the dough up to the point of scooping, then wrap it tightly in plastic wrap or store it in an airtight container in the refrigerator. When you’re ready to bake, just scoop the chilled dough onto baking sheets and bake as instructed. This method maintains the cookies’ chewy texture and rich flavor, ensuring they come out just as delicious. Additionally, you can freeze the scooped dough for up to 3 months; simply bake from frozen, adding an extra minute or two to the baking time for fresh, warm cookies with minimal effort.

Sourdough Chocolate Peanut Butter Swirl Cookies Recipe FAQs
How do I select the perfect sourdough discard?
Absolutely! When choosing sourdough discard for your cookies, look for a discard that’s been recently fed and is bubbly, as this indicates it’s active and has wonderful flavor. If your discard has developed a strong, sour smell or has dark spots, it’s best to avoid using it, as it may affect the taste of your cookies.
How should I store the cookies?
I recommend storing your Sourdough Chocolate Peanut Butter Swirl Cookies in an airtight container at room temperature for 3–5 days. This keeps them chewy and delicious. If you live in a particularly humid climate, consider refrigerating them for up to 1 week—they will still taste great when returned to room temperature!
Can I freeze these cookies?
Very much! To freeze your cookies, first arrange them in a single layer on a baking sheet and freeze until solid, which should take about 1-2 hours. Then, transfer them to an airtight freezer bag or container. They can be stored this way for up to 6 months. For the best taste, thaw them at room temperature or microwave for about 10-15 seconds until warmed.
What should I do if my cookies spread too much while baking?
If you notice your cookies spread excessively, it may be due to overly soft butter or the dough being too warm. To remedy this, chill your cookie dough for 30-60 minutes before baking. This helps them hold their shape better. Additionally, ensure your butter is softened but not melting—aim for a creamy texture that holds its shape.
Are these cookies safe for pets or people with allergies?
When baking Sourdough Chocolate Peanut Butter Swirl Cookies, be mindful of the ingredients, especially peanut butter, which can be harmful to dogs. If you’re baking for a dog owner, consider offering a pet-friendly treat instead. Always check for allergies to common ingredients like gluten and nuts; you can swap out the flour for a gluten-free blend and use alternative nut butters for allergy considerations.
