In a large mixing bowl, whisk together the egg, egg yolk, sourdough discard, white sugar, brown sugar, vanilla, pumpkin purée, and oil until smooth.
1 egg, 1 egg yolk, ⅓ (80g) cup sourdough discard, 1 teaspoon vanilla extract, ¾ (175g) cup 100% pumpkin purée, ¼ (60g) cup avocado oil , ½ (100g) cup granulated white sugar, ¼ (50g) cup brown sugar
Sourdough Discard Swap: If you don't want to use discard, add the additional milk to the wet ingredients above and the additional flour to the step below.
1/4 (30g) cup all-purpose flour, 3 (45g) Tbsp whole milk
In a medium bowl, whisk together the flour, cinnamon, ginger, nutmeg, cardamom, baking soda, baking powder, and salt.
2 (250g) cups all-purpose flour, 2 teaspoons ground cinnamon, ½ teaspoon ground ginger, ¼ teaspoon ground nutmeg, ⅛ teaspoon ground cardamom, 1 teaspoon baking powder, ¾ teaspoon baking soda, ¾ teaspoon fine sea salt
Add the dry ingredients to the wet, and gently combine everything until no streaks of flour remain. Do not overmix or the batter will become tough.
Optional Overnight Fermentation: Cover the bowl tightly with plastic wrap and refrigerate for 8–12 hours for added fermentation benefits.
