Step‑by‑Step Instructions for Soft and Chewy Sourdough Peanut Butter Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it’s heating, line a baking sheet with parchment paper, creating a nonstick surface for your cookies. This simple step ensures an easier cleanup later on and sets the stage for perfectly baked sourdough peanut butter cookies that won’t stick.
Step 2: Cream the Butters and Sugars
In a mixing bowl, combine softened unsalted butter and natural creamy peanut butter. Using a hand mixer or stand mixer, beat them together with granulated and brown sugar until the mixture is light and fluffy, roughly 2-3 minutes. This airy texture will give your cookies that delightful chewiness, perfect for sourdough peanut butter cookies.
Step 3: Incorporate Wet Ingredients
Add one whole egg, along with an additional egg yolk, to the creamed mixture, followed by the vanilla extract and your sourdough starter. Mix until the ingredients are smooth and well integrated, about 1-2 minutes. The sourdough starter adds a tangy flavor that beautifully complements the sweetness of the peanut butter.
Step 4: Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking soda, and salt. This ensures even distribution of the leavening ingredients and helps prevent lumps. The combination of these dry ingredients is essential for achieving the soft and chewy texture that makes these sourdough peanut butter cookies so irresistible.
Step 5: Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture while folding gently with a spatula. Mix until just combined, taking care not to overwork the dough. Overmixing can lead to tough cookies, so stop as soon as you no longer see any flour. The dough should be sticky and thick, promising delicious cookies ahead.
Step 6: Shape the Dough
Using your hands, roll the dough into 1-inch balls. Once shaped, roll each ball in granulated sugar to create a delightful sweet exterior. Place the coated dough balls on your prepared baking sheet, spacing them about 2 inches apart to allow for spreading during baking. Your soon-to-be-baked sourdough peanut butter cookies are ready for the oven!
Step 7: Bake the Cookies
Bake the cookies in your preheated oven for about 12 minutes. They should appear puffed up and slightly set around the edges, while staying gooey in the center. This balance of textures is key to achieving the perfect soft and chewy sourdough peanut butter cookies that you and your family will love.
Step 8: Cool and Enjoy
Once baked, remove the cookies from the oven and let them cool on the baking sheet for a few minutes. This allows them to firm up slightly before transferring to a wire rack to cool completely. Enjoy them warm or at room temperature as a delightful treat that brings comfort and joy to any occasion.

Expert Tips for Sourdough Peanut Butter Cookies
- Measure Accurately: Use a kitchen scale to ensure ingredient ratios are precise, which is essential for achieving the perfect chewy texture in your sourdough peanut butter cookies.
- Chill the Dough: For enhanced flavor and to prevent spreading, refrigerate the cookie dough for at least 30 minutes before baking.
- Mind the Oven: Watch your cookies closely in the last minutes of baking; every oven varies and you want them slightly gooey for that ideal softness.
- Experiment with Flavors: Feel free to mix in chocolate chips or nuts for added flavor; just keep the overall texture in mind to maintain that chewiness!
- Sourdough Starter Options: Don’t hesitate to use either active sourdough starter or discard; both will impart a delightful tang to your cookies.

Feel free to get creative with these delightful cookies, enhancing flavors and customizing them to your liking!
- Chocolate Chip: Add 1 cup of chocolate chips to the dough for a rich and decadent treat. The combination of peanut butter and chocolate is simply irresistible!

- Coconut Bliss: Fold in shredded coconut for a tropical twist that’s both chewy and sweet. Pairing coconut with peanut butter creates a delightful harmony of flavors.
- Fruit Infusion: Add dried cranberries or raisins to sweeten the cookies naturally and introduce a chewy texture. Their tartness beautifully complements the creamy peanut butter.
- Vegan-Friendly: Replace eggs with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water) for a vegan version that doesn’t compromise texture. These cookies will still be soft and chewy!
- Chili Heat: For an unexpected kick, toss in a pinch of cayenne pepper or sprinkle some chili flakes into the dough. This spicy twist balances out the sweetness and makes for an adventurous treat!

Soft and Chewy Sourdough Peanut Butter Cookies Recipe FAQs
What sourdough starter should I use?
You can use either an active sourdough starter or cooled sourdough discard. If using an active starter, make sure it has been fed recently and is bubbly for the best flavor and texture. Discard is also excellent for baking without waste, so you can't go wrong!
How should I store these cookies?
Store your baked sourdough peanut butter cookies in an airtight container at room temperature for up to 1 week. If you want them to last longer, keep them in the refrigerator for up to 2 weeks, just be sure to wrap them well to avoid drying out.
Can I freeze the cookie dough?
Absolutely! To freeze the dough, shape it into 1-inch balls, coat them in sugar, and place them on a parchment-lined baking sheet. Freeze the dough balls for 1-2 hours until firm, then transfer them to an airtight container or zip-top bag. They'll keep in the freezer for up to 3 months. When you're ready to bake, just pop them in the oven directly from the freezer—add a couple of extra minutes to the baking time!
What should I do if my cookies turn out too flat?
If your baked cookies spread too much, here are a few troubleshooting tips: ensure your butter is softened but not too warm; chilling the dough for at least 30 minutes before baking can help prevent excessive spreading. Check the freshness of your baking soda, as old leavening agents may not rise properly. Lastly, using the right flour measure (spooned and leveled) is crucial for the right dough consistency.
Can I make these cookies vegan?
Yes, you can! Substitute the egg with a flax egg—mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for 5-10 minutes to thicken. Use vegan butter in place of unsalted butter, and enjoy these delicious sourdough peanut butter cookies that fit a vegan diet!
How do I know when cookies are done baking?
For perfect soft and chewy texture, bake the cookies for about 12 minutes, watching closely as they should be puffed and slightly set around the edges while remaining gooey in the center. They will firm up as they cool, so don’t be tempted to bake them longer unless you want a firmer cookie. Enjoy your baking adventure!
