How to Make Sourdough Peanut Butter Cookies
Step 1. Begin by melting the butter in a mixing bowl until it’s completely liquefied. This step ensures that the butter can easily combine with the sugars, contributing to the lush, tender texture of the cookies. Watch for any bubbles that might form, indicating the butter is warm enough. Let it cool slightly before moving on to the next step.
Step 2. Once the butter has cooled, add in both the white granulated sugar and the dark brown sugar. Using a rubber spatula or wooden spoon, mix these ingredients together until they’re well combined. You’re looking for a smooth and cohesive mixture, which indicates that the sugars have integrated well with the butter.
Step 3. To the sugar and butter mixture, add the creamy peanut butter. Stir until it’s fully incorporated, creating a smooth and creamy blend. This mixture should be thick but well combined, with no streaks of peanut butter or sugar visible.
Step 4. Next, incorporate the sourdough starter into your mixture. Make sure to measure the starter after stirring it down well, as this ensures you get an accurate amount. Mix it in until well combined; the batter should have a slightly thicker texture due to the added starter.
Step 5. Break the egg into the bowl and add the vanilla bean paste or extract. Mix these in thoroughly until the batter is uniform, ensuring that there are no visible traces of egg. The egg not only adds moisture but also helps bind all the ingredients together.
Step 6. In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and kosher salt. This step helps distribute the leavening agents evenly throughout the flour, ensuring consistent rising and flavor. The mixture should be light and lump-free.
Step 7. Gradually add the dry flour mixture to the wet ingredients, stirring gently as you do so. This is where it’s important to combine them thoughtfully to prevent over-mixing. You’re aiming for a dough that is soft but still holds its shape, indicating that it’s ready for the next stage.
Step 8. Allow the cookie dough to rest for about 5 to 10 minutes. During this time, the flour will hydrate fully, giving the cookies a better texture once baked. You should notice the dough firm up slightly as it rests.
Step 9. Preheat your oven to the desired temperature, ensuring it’s ready when you’re prepared to bake. While the oven is heating, scoop tablespoons of dough and roll them into balls. Then, roll the dough balls in granulated sugar before placing them onto a prepared baking sheet. This step creates a lovely sweet crust on the cookies.
Step 10. Bake the cookies until they’re lightly golden around the edges. Watch for a slight puffing of the dough, which indicates they are baking correctly. As they cool, the aroma will fill your kitchen, creating a warm, inviting atmosphere.

Pro Tips for Best Results
- Use room temperature ingredients when possible for better integration.
- Don’t over-mix the dough to keep cookies tender.
- Chill the dough if it becomes too warm while shaping.
- Adjust baking times based on your oven’s calibration for even results.
- Allow cookies to cool slightly on the baking sheet before transferring them to a wire rack.
Common Mistakes to Avoid
- Using cold ingredients: Cold butter or eggs can result in uneven mixing, leading to dense cookies. Always allow ingredients like butter and eggs to come to room temperature for better results.
- Over-mixing the dough: This can lead to tough cookies. Mix until just combined, so they maintain their tender texture.
- Not measuring the flour correctly: Packing flour while measuring can lead to too much being added, resulting in dry cookies. Use the spoon-and-level method to accurately measure.
- Skipping the dough resting period: Not letting the dough rest can prevent the cookies from spreading properly. Give the dough a few minutes to hydrate for the best texture.
- Underbaking or overbaking the cookies: Baking them for too little time can make them doughy, while too much time can dry them out. Look for lightly golden edges to know they are done.
- Not using a parchment-lined baking sheet: This can cause cookies to stick and lose their shape. Always line with parchment for easier removal and clean-up.
Variations & Substitutions
Consider adding chocolate chips or chopped nuts for additional texture and flavor. You can also experiment with different nut butters if desired, as long as they have a similar consistency to peanut butter. For a different twist, try using a mix of standard granulated sugar and a natural sweetener, maintaining the same total amount of sweet ingredients.
Storage & Reheating
Store cookies at room temperature in an airtight container for up to a week to keep them fresh. For longer storage, they can be placed in the refrigerator, where they can last for about two weeks. If you prefer, cookies also freeze well; wrap them in plastic wrap and then place them in a freezer bag for up to three months. When reheating, a quick toss in the microwave for a few seconds will help restore their soft texture.
Frequently Asked Questions
