Sourdough Cookies

These richly spiced, chewy sourdough cookies are an excellent way to use excess sourdough starter or discard, which is never in short supply for habitual sourdough bakers. The trick to the cookie's bold character is using as many freshly ground spices as possible—their strong punchiness is pleasantly balanced by the rich flavor of the flours and unrefined sweeteners. A spice grinder is best for preparing whole spices into a fine powder for measuring, but a clean coffee mill works just as well. Using this combination of stone-ground spelt, rye, and buckwheat flours leads to a robust grain flavor, thick cookie, and slight chew. This is a thick, hefty dough; Sarah Owens sources heavy-duty vintage ice cream scoops to make portioning easier. For a stronger flavor and more tender crumb, ferment the dough in the refrigerator for up to 5 days before scooping and baking.

Ingredients

Dough

  • 2 ¼ cups whole-grain spelt flour (such as Bob's Red Mill) (about 9 3/4 ounces)

  • 2 cups whole-grain dark rye flour (such as Bob's Red Mill) (about 8 1/4 ounces)

  • .50 cup whole-grain buckwheat flour (such as Bob's Red Mill) (about 2 1/4 ounces)

  • 1 tablespoon ground cinnamon

  • 1 tablespoon ground ginger

  • 2 teaspoons ground cardamom

  • 1.50 teaspoons ground turmeric

  • 1 teaspoon ground white pepper

  • 1 teaspoon ground black pepper

  • 1 teaspoon ground allspice

  • 1 teaspoon baking powder

  • 1 teaspoon baking soda

  • ¾ teaspoon ground cloves

  • ¾ teaspoon ground nutmeg

  • ¾ teaspoon kosher salt

  • 1 cup unsalted butter (8 ounces), at room temperature

  • 1 cup loosely packed unrefined coconut sugar or light brown sugar

  • ¾ cup granulated sugar

  • 2 large eggs, at room temperature

  • .50 cup unsulfured molasses (such as Grandma's)

  • cup mature sourdough starter or sourdough starter discard (about 2 1/2 ounces), at room temperature

  • 1 teaspoon vanilla extract

Topping

  • cup granulated sugar

  • ¾ teaspoon ground cinnamon

Directions

Make the dough:

  1. Whisk together spelt flour, rye flour, buckwheat flour, cinnamon, ginger, cardamom, turmeric, white pepper, black pepper, allspice, baking powder, baking soda, cloves, nutmeg, and salt in a medium bowl; set aside.

  2. Beat butter, coconut sugar, and granulated sugar in bowl of a stand mixer fitted with the paddle attachment on medium speed until pale and slightly fluffy, about 3 minutes. Add eggs, 1 at a time, beating well after each addition. Add molasses, sourdough starter, and vanilla. Beat until mixture is well combined and resembles ribbons being pulled by the paddle, about 3 minutes, stopping occasionally to scrape down sides of bowl.

  3. Reduce mixer speed to low; gradually add flour mixture to butter mixture, beating just until incorporated and smooth, about 1 minute. (Do not overmix. Dough will be thick and soft.) Cover bowl tightly with plastic wrap, and chill at least overnight (12 hours) or up to 5 days. The longer the dough chills, the fluffier and tangier the cookies will be.

  4. Remove dough from refrigerator, and let stand, covered, at room temperature until slightly softened, 1 to 2 hours. During final 30 minutes of standing time, preheat oven to 375°F with racks in upper third and lower third positions. Line 4 baking sheets with parchment paper.

Make the topping:

  1. Stir together granulated sugar and cinnamon in a small bowl; set aside.

  2. Using a 2 1/4-inch cookie scoop, divide dough into 2 1/2-ounce portions, leaving 1 side of each scoop flat. Roll the rounded tops and sides of each dough portion in cinnamon-sugar topping. Place dough scoops, flat sides down, at least 2 1/2 inches apart on prepared baking sheets.

  3. Bake 2 baking sheets of cookies in preheated oven until cookie edges are set and slightly firm and tops are crackled with dull matte, not glossy, cracks, 14 to 18 minutes, rotating baking sheets between top and bottom racks halfway through bake time. Let cookies cool on baking sheets 10 minutes. Transfer cookies to a wire rack, and let cool completely, about 30 minutes. Repeat baking process with remaining cookies.

Make Ahead

Dough can be made up to 5 days ahead and stored in an airtight container in refrigerator.
