Ingredients & Substitutions

Here are some notes on key ingredients. For a full list of ingredients, check out the recipe card below.

• Sourdough Discard- Adding sourdough discard helps use up extra starter and prevent waste. The chocolate and peppermint flavors in the cookies mostly mask the sourdough taste.
• Dutch-Processed Cocoa Powder- Dutch-processed cocoa is less acidic than natural cocoa, giving the cookies a smoother, more balanced chocolate flavor.
• White Chocolate Chips- I used white chocolate chips for this recipe, but feel free to swap in white chocolate chunks or chopped baking chocolate for a different texture.
• Peppermint Candy- You can use either crushed peppermint starlight candies or candy canes - both add the perfect holiday crunch and minty flavor.
• Butter- Make sure your butter is softened so it mixes easily into the dough.
• All-Purpose Flour- All-purpose flour provides structure and a soft, chewy texture. For best results, measure it by weight or use the spoon-and-level method.
• Granulated & Brown Sugar- Combining both sugars gives the cookies a balanced sweetness and a chewy texture.
• Baking Soda- Baking soda helps the cookies spread and creates a soft, chewy center with slightly crisp edges.
• Kosher Salt- I use Diamond Crystal Kosher Salt. If substituting with Morton's or table salt, use a bit less or weigh it in grams to avoid over-salting.

How to Make White Chocolate Peppermint Sourdough Cookies

Here is how to make peppermint white chocolate cookies with sourdough discard.

Step 1: Mix dry ingredients. In a small bowl, whisk together the flour, cocoa powder, baking soda, and kosher salt. Set aside.

Step 2: Combine wet ingredients. In a large mixing bowl, use a hand mixer (or stand mixer) to cream together the softened butter, brown sugar, and granulated sugar until well combined. Add the eggs, beating well until light and fluffy. Mix in the sourdough discard, vanilla extract, and peppermint extract until smooth.

Step 3: Mix cookie dough. Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until a thick dough forms and no dry flour remains visible. Gently fold in the white chocolate chips until evenly distributed throughout the dough.

Step 4: Chill the dough. For the best flavor and texture, cover the dough and refrigerate for at least 1 hour (or up to 48 hours). If you’re short on time, you can bake the dough immediately as long as it’s not overly soft.

Step 5: Portion cookie dough. When ready to bake, preheat your oven to 350°F and line a baking sheet with parchment paper. Use a tablespoon or small cookie scoop to drop heaping tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Step 6: Bake the cookies. Bake the cookies for 9-11 minutes or until the centers are just set. While the cookies are still hot, sprinkle them with crushed peppermint candy so it sticks.

Step 7: Cool. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

How to Store

Store sourdough white chocolate peppermint cookies in an airtight container at room temperature for up to one week. For longer storage, freeze the cookies for up to 6 months. Thaw at room temperature before serving.

If you want to make the dough ahead, you can keep it in the fridge for up to 2 days or freeze it for up to 2 months. For easy baking later, I suggest freezing the dough in pre-portioned balls.

• Sourdough Discard- The sourdough discard adds a unique, tangy flavor to these shortbread cookies. Of course, it’s also just a great way to use your extra starter, so nothing goes to waste.
• Butter- Butter is what makes shortbread cookies so rich and delicious. Make sure it’s softened before you start so it mixes easily with the sugar.
• Powdered Sugar- Powdered sugar is used in shortbread cookies for a soft, tender, melt-in-your-mouth texture. These cookies are not meant to be too sweet, which is why there’s only ¾ cup of powdered sugar in the dough. They’re perfect for those who prefer a less sugary treat.
• All-Purpose Flour- It's best to weigh the flour with a scale. However, if you’re using cups, spoon it into the cup and level it off to avoid using too much.
• Vanilla Extract- A little vanilla adds warmth and rounds out the flavor of the cookies.
• Kosher Salt- I use Diamond Crystal Kosher Salt. You may want to use a little less if you’re using a different type (like table salt or Morton’s).

How to Make Sourdough Shortbread Cookies

Here is how to make shortbread cookies with sourdough discard.

Step 1: Cream butter and sugar. In a large mixing bowl, use a hand mixer or stand mixer to beat the softened butter and powdered sugar together until the mixture is smooth and creamy.

Step 2: Add wet ingredients. Add the sourdough discard and vanilla extract to the bowl, mixing until fully combined.

Step 4: Shape and chill dough. Lay a piece of plastic wrap on your counter. Transfer the dough to the center of the wrap and use the wrap to shape the dough into a log or disc. The size of the log will determine how big your cookies will be (mine was about 2 inches in diameter). If using cookie cutters, you can shape the dough into a disc for rolling out instead. Wrap the dough tightly and refrigerate for at least 1 hour, or up to 2 days, to firm it up.

Step 5: Preheat oven. When ready to bake, preheat the oven to 350℉ and line a baking sheet with parchment paper.

Step 6: Cut cookie dough. If you shaped the dough into a log, unwrap it and cut it into ¼-inch thick slices with a sharp knife. If using cookie cutters, roll the dough out on a lightly floured surface to about ¼-inch thick, and use the cookie cutters to create your desired shapes. Re-roll any scraps to cut out additional cookies. Use a fork or skewer to dock each cookie, which helps prevent them from puffing up too much while baking and adds a decorative touch.

Step 7: Bake cookies. Transfer the cookies to the prepared baking sheet, leaving about an inch of space between each one. Bake in the preheated oven for 15-17 minutes, or until the edges are deeply golden brown and the tops are just starting to brown.

Step 8: Cool. Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. The cookies will continue to crisp up as they cool.

How to Store

Store sourdough shortbread cookies in an airtight container for 5-7 days at room temperature.

For longer storage, freeze cookies for up to 3 months. Thaw at room temperature.

• Sourdough Discard- Adding sourdough discard to thumbprint cookies reduces food waste while giving them a unique, subtly tangy flavor.
• Raspberry Jam- Raspberry jam is a classic choice and pairs beautifully with the almond extract. However, feel free to experiment with other jam flavors you enjoy, such as strawberry, apricot, or cherry.
• Almond Extract- Almond extract adds the signature flavor to these thumbprint cookies, but remember that a little goes a long way! If you’re not a fan of almond, you can easily substitute it with extra vanilla extract.
• All-Purpose Flour- Use a scale or spoon the flour into the measuring cup and level it off for best results. Too much flour can result in dry, crumbly cookies.
• Granulated Sugar- Sweetens the cookies and creates a slightly crunchy, sparkly exterior when rolled before baking - perfect for the holidays!
• Butter- Make sure the butter is softened before making the dough so everything mixes together easily.
• Kosher Salt- I use Diamond Crystal Kosher Salt. If you're using table salt, use about half the amount.

How to Make Sourdough Thumbprint Cookies

Here is how to make raspberry almond thumbprint cookies with sourdough discard.

Step 1: Cream butter and sugar. In a large mixing bowl, use a hand mixer or stand mixer to beat the softened butter and granulated sugar together until the mixture is light and fluffy.

Step 2: Add wet ingredients. Mix in the sourdough discard, vanilla extract, and almond extract until everything is well combined.

Step 5: Portion cookie dough. Scoop tablespoon-sized portions of the chilled dough and roll them into balls. Roll each ball in the granulated sugar, then place them evenly spaced on the prepared baking sheet, leaving about 2 inches between each cookie.

Step 6: Fill with jam. Use your thumb or the back of a wooden spoon to make a small indentation in the center of each cookie dough ball. If any cracks form around the edges, gently press them together as best you can. Fill each indentation with about ¼ teaspoon of jam, being careful not to overfill to prevent leaks during baking.

Step 7: Bake cookies. Bake the cookies for about 13-15 minutes or until the edges start to turn golden brown.

Step 8: Cool. Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. The jam will set as the cookies cool.

• Sourdough Discard- Using sourdough discard in these cookies not only helps reduce food waste, but also adds moisture and gives them a unique twist that sets them apart from traditional peanut butter blossoms.
• Natural Peanut Butter- Choose natural peanut butter made with just peanuts and salt. Smooth peanut butter works best because chunky can make the cookies crumbly. I like Teddie Peanut Butter since it's made in my home state of Massachusetts.
• Hershey's Kisses- I used classic Hershey's Milk Chocolate Kisses, but you can switch it up with different flavors or any chocolate candy you like.
• All-Purpose Flour—This flour gives the cookies a soft texture while providing enough structure for the Hershey’s Kiss. Measure carefully using a scale or the spoon-and-level method to avoid dry cookies.
• Granulated Sugar- Rolling the dough in granulated sugar gives the cookies a sweet, crispy coating and a little sparkle - perfect for the holidays.
• Butter- Make sure the butter is softened before making the dough so everything mixes smoothly.
• Kosher Salt- I use Diamond Crystal Kosher Salt. If you're using table salt, use half the amount.

• Sourdough Discard- Using extra sourdough starter in molasses cookies is a great way to add moisture and a subtle sourdough flavor.
• Unsulphured Molasses- You can find unsulphured molasses at most grocery stores. My favorite is Grandma's Original Molasses for its mild, sweet flavor.
• Ground Spices- A blend of primarily ground ginger and cinnamon with a pinch of clove and nutmeg.
• All-Purpose Flour- Provides enough structure to create a soft yet chewy cookie.
