This recipe calls for Sourdough Starter discard vs. active starter. This is because our Test Kitchen uses the starter primarily for flavor here and using baking soda and powder for the leavening action. Use starter discard plus chemical leaveners in recipes like quick breads, cakes, and cookies. Active starter better mimics the slow rise leavening action of yeast (in breads and rolls vs. quick acting leaveners like baking soda and powder.


  • 192 grams white whole wheat flour (1½ cups)

  • 1 1/2 teaspoons kosher salt

  • 1 1/2 teaspoons baking powder

  • 1 teaspoon baking soda

  • 1 teaspoon ground cinnamon

  • 1 teaspoon ground ginger

  • 1/4 teaspoon cardamom

  • 3/4 cup canned pumpkin

  • 3/4 cup sourdough discard

  • 3/4 cup maple syrup

  • 1/3 cup canola, avocado, or olive oil

  • 2 large eggs

  • 2 teaspoons orange zest

  • 1 teaspoon vanilla

  • 1/4 cup raw pumpkin seeds (pepitas)

  • 1 tablespoon turbinado or coarse sugar


  1. Preheat oven to 350°F. Grease bottom and ½ inch up sides of a 9x5-inch loaf pan. Line pan with a 9-inch-wide strip of parchment paper, extending the parchment over the two long sides of pan (to lift the bread from the pan after baking).

  2. In a large bowl combine the first 7 ingredients (through cardamom). Make a well in the center of the flour mixture. In a medium bowl whisk together next 7 ingredients (through vanilla). Add the pumpkin mixture to the flour mixture. Stir until just moistened. Spoon into prepared pan. Top with pepitas and sugar.

  3. Bake 50 to 55 minutes until a toothpick comes out clean. Cool in pan 15 minutes. Remove and cool completely on a wire rack.

  4. Store at room temperature up to 2 days or store wrapped bread in the refrigerator up to 5 days.
