Ingredients
Makes approximately 24 cookies.
- 1 cup (227g) unsalted butter, softened
- ¾ cup (150g) granulated sugar
- ¼ cup (50g) powdered sugar
- ½ cup (120g) sourdough discard (unfed starter)
- 1 large egg
- 1 teaspoon vanilla extract
- 2½ cups (315g) all-purpose flour
- ½ teaspoon salt
- Optional: coarse sugar for sprinkling
Equipment Needed
- Large mixing bowl
- Electric mixer or stand mixer
- Measuring cups and spoons
- Baking sheets
- Parchment paper
- Cookie cutters (optional)
- Rolling pin (if making cut-out cookies)
- Cooling rack
Instructions
Step 1: Prepare the Dough
In a large mixing bowl, beat the softened butter, granulated sugar, and powdered sugar together until light and fluffy. This process usually takes about 2–3 minutes with an electric mixer. Proper creaming helps create a tender cookie texture.
Add the sourdough discard, egg, and vanilla extract. Mix until fully combined. The mixture may appear slightly curdled at first, but it will smooth out once the flour is added.
Step 2: Add Dry Ingredients
In a separate bowl, whisk together the flour and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until a soft dough forms. Avoid overmixing, as this can make the cookies tough.
The dough should be smooth and easy to handle. If it feels overly sticky, add an additional tablespoon of flour.
Step 3: Chill the Dough
Divide the dough into two portions and flatten each into a disk. Wrap tightly in plastic wrap and refrigerate for at least 1 hour. Chilling the dough allows the flavors to develop and helps the cookies maintain their shape during baking.
For even better flavor, refrigerate overnight.
Step 4: Preheat the Oven
When ready to bake, preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
Remove one disk of dough from the refrigerator and allow it to sit for about 5 minutes if it feels too firm to roll.
Step 5: Roll and Cut
On a lightly floured surface, roll the dough to approximately ¼ inch thickness. Use cookie cutters to cut desired shapes.
Transfer the cut cookies to the prepared baking sheets, spacing them about 1 inch apart.
If desired, sprinkle the tops with coarse sugar for extra sparkle and crunch.
Step 6: Bake
Bake for 10–12 minutes, or until the edges are lightly golden. The centers should remain pale for a tender texture.
Avoid overbaking, as butter cookies continue to firm up as they cool.
Step 7: Cool
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack. Let them cool completely before decorating or storing.
Decorating Ideas
These sourdough butter cookies are delicious plain, but they can also be dressed up for special occasions.
Sugar Topping
Before baking, sprinkle with colored sugar or sanding sugar for a festive appearance.
Chocolate Drizzle
Melt dark, milk, or white chocolate and drizzle over cooled cookies. Let the chocolate set before serving.
Royal Icing
Decorate with royal icing for holidays, birthdays, or themed celebrations.
Sandwich Cookies
Spread jam, chocolate ganache, or buttercream frosting between two cookies to create elegant sandwich treats.
Storage Tips
Store cookies in an airtight container at room temperature for up to 1 week.
For longer storage, freeze baked cookies in a freezer-safe container for up to 3 months. Thaw at room temperature before serving.
You can also freeze the unbaked dough for up to 2 months. Wrap tightly and thaw overnight in the refrigerator before rolling and baking.
Baker’s Notes
Understanding Sourdough Discard
Sourdough discard is the portion of starter removed during feeding. It contains flour, water, and beneficial fermentation byproducts that add flavor to baked goods. This recipe works best with unfed discard that has been refrigerated.
Flour Variations
All-purpose flour provides the ideal balance of tenderness and structure. However, you can substitute up to 25% of the flour with whole wheat flour for a nuttier flavor.
Flavor Enhancements
Try adding:
- 1 teaspoon almond extract
- Lemon or orange zest
- Cinnamon or cardamom
- Finely chopped nuts
These additions pair beautifully with the tangy sourdough notes.
Serving Suggestions
Serve these cookies alongside coffee, tea, or hot chocolate. They also make a thoughtful homemade gift when packaged in decorative tins or gift boxes.
For dessert platters, pair them with fresh berries, chocolate truffles, and shortbread cookies. Their buttery texture and subtle sourdough tang provide a unique contrast to sweeter treats.
Conclusion
Sourdough Butter Cookies are an excellent way to transform extra sourdough discard into something truly special. Their rich buttery flavor, delicate texture, and slight tang make them stand out from ordinary sugar cookies. Easy to prepare and endlessly customizable, these cookies are perfect for family gatherings, holiday celebrations, or everyday snacking. Once you try this recipe, you’ll find yourself saving sourdough discard just for another batch of these irresistible homemade cookies.
