Step‑by‑Step Instructions for Sourdough Peanut Butter Blossom Cookies
Step 1: Prepare Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, and a pinch of salt until evenly combined. This step is essential for a uniform cookie texture, so set the bowl aside while you work on the wet ingredients.
Step 2: Cream Butters and Sugars
Using a stand mixer or a large mixing bowl, cream ½ cup of room-temperature unsalted butter with ½ cup granulated sugar and ½ cup brown sugar. Beat for 2-3 minutes until the mixture is fluffy and light in color. This process incorporates air, ensuring your Sourdough Peanut Butter Blossom Cookies turn out soft and chewy.
Step 3: Incorporate Wet Ingredients
Add 1 egg, ½ cup of creamy peanut butter, ½ cup of sourdough discard, and 1 teaspoon of vanilla extract to the creamed butter and sugars. Mix on medium speed until thoroughly combined, scraping down the sides of the bowl as needed to ensure no pockets of ingredients remain, creating a smooth cookie dough base.
Step 4: Combine Dry and Wet Mixtures
Gradually incorporate the dry ingredient mixture into the wet mixture, mixing on low speed until just combined and no flour streaks remain. This helps maintain the texture and ensures your Sourdough Peanut Butter Blossom Cookies are consistent throughout. Be careful not to overmix, which could lead to tough cookies.
Step 5: Chill the Dough
Wrap the cookie dough in plastic wrap and refrigerate for at least 4 hours or overnight. Chilling is crucial for maintaining the shape of your cookies during baking, preventing them from spreading too much. This also enhances the flavor as the ingredients meld together beautifully.
Step 6: Preheat and Prepare Baking Sheet
Preheat your oven to 350°F (175°C) approximately 15 minutes before baking. While it heats, line a baking sheet with parchment paper for easy cookie removal. This step ensures your Sourdough Peanut Butter Blossom Cookies bake evenly and come off the tray without sticking.
Step 7: Shape Cookies
Once chilled, scoop tablespoon-sized balls of dough and roll them in granulated sugar until coated. Place them 2 inches apart on the prepared baking sheet, as they will spread slightly during baking. This spacing prevents them from merging and helps achieve that ideal cookie shape.
Step 8: Bake the Cookies
Bake the cookies in your preheated oven for 9-11 minutes, or until they are slightly cracked and the bottoms are golden brown. The edges should look set while the center remains soft, which is perfect for achieving that chewy texture characteristic of Sourdough Peanut Butter Blossom Cookies.
Step 9: Add Hershey’s Kisses
Immediately after removing the cookies from the oven, gently press a Hershey’s Kiss into the center of each warm cookie. This melting chocolate adds that signature touch, transforming your cookies into delightful treats. Allow them to cool slightly on the baking sheet for a few minutes.
Step 10: Cool and Serve
Transfer the cookies to a wire rack to cool completely. Once they have cooled enough to handle, they are ready to be enjoyed! These Sourdough Peanut Butter Blossom Cookies make a perfect pairing with a glass of cold milk or warm coffee for that delightful treat.

How to Store and Freeze Peanut Butter Blossom Cookies
Room Temperature: Store cooled cookies in an airtight container at room temperature for up to 5-7 days to maintain freshness.
Fridge: If you prefer your cookies chilled, they can be kept in an airtight container in the fridge for up to a week; just allow them to come to room temperature before enjoying.
Freezer: Freeze cookie dough balls for up to two months. To bake, simply thaw in the fridge overnight before baking for a warm treat anytime.
Reheating: Warm cookies in the microwave for 10-15 seconds for that fresh-out-of-the-oven taste, perfect for savoring with a glass of milk!
Expert Tips for Sourdough Peanut Butter Blossom Cookies
-
Chill the Dough: Ensure you refrigerate the dough for at least 4 hours. This step prevents spreading and enhances the flavors in your Peanut Butter Blossom Cookies.

Use Processed Peanut Butter: Opt for brands like Jiff or Skippy for the best texture. Natural peanut butter can alter the consistency, making cookies less chewy.

Check Baking Leaveners: Always verify that your baking soda and baking powder are fresh to achieve the perfect rise in your cookies. Stale leaveners can lead to dense cookies.
-
Monitor Baking Time: Every oven is slightly different. Keep an eye on your cookies during the last few minutes of baking to avoid overcooking; a light golden bottom is ideal.

Sourdough Peanut Butter Blossom Cookies Recipe FAQs
How should I select the right sourdough discard?
Absolutely! When choosing sourdough discard, it’s best to use it within a week of feeding to ensure optimal flavor. Look for discard that has a pleasant tangy aroma and no signs of discoloration. Discard that is too old or has dark spots all over may not yield the best results in your cookies.
What’s the best way to store leftover cookies?
You can store your Sourdough Peanut Butter Blossom Cookies in an airtight container at room temperature for 5-7 days. Make sure the cookies have completely cooled before sealing them to retain their chewy texture. For longer storage, you can refrigerate them for up to a week.
Can I freeze the cookie dough?
Very much so! To freeze your cookie dough balls, scoop and shape them as instructed, then lay them on a baking sheet lined with parchment paper. Freeze until solid, then transfer the cookie dough balls to a freezer-safe bag or container. They can be stored for up to 2 months. When ready to bake, just thaw the dough in the fridge overnight and bake as usual.
I find my cookies are flattening out too much after baking. What could be wrong?
This can happen if the dough isn’t chilled long enough, leading to cookies that spread too much. Ensure you are chilling the dough for at least 4 hours, or ideally overnight. Additionally, check that your leavening agents (baking soda and powder) are fresh, as stale ingredients can affect texture.
Are these cookies suitable for people with nut allergies?
Certainly! If you need a nut-free version of the Sourdough Peanut Butter Blossom Cookies, simply substitute the peanut butter with sunflower seed butter. This not only works well in the recipe but also maintains the rich, creamy taste we love in cookies, ensuring everyone can enjoy a tasty treat!
What types of toppings can I use besides Hershey’s Kisses?
You can get creative with your toppings! I often recommend trying Caramel Kisses, white chocolate Hugs, or even mini peanut butter cups for a delightful twist. Experimenting with colored sugar before baking can also add a festive touch for holiday gatherings.
