Sourdough Bread Muffins or Loaf
- 1⅓ cups (190 g) all-purpose flour
- ¾ cup (95 g) white whole wheat flour
- ¼ cup (57 g) granulated sugar
- 2 teaspoons baking powder
- ¼ teaspoon baking soda
- ½ teaspoon salt
- 1-1⅓ cups (150g-185 g) raisins
- 2 teaspoons orange zest or 1 drop orange extract
- 110 g sourdough starter (unfed or discard, room temperature)
- 1 large egg, room temperature
- 6 tablespoons (85 g) butter, melted
Choose ONE dairy option:
- Option 1: 1½ cups (360 mL) buttermilk
- Option 2: 1½ cups (360 mL) heavy cream + 1 tablespoon lemon juice or white vinegar
Preheat the oven to 375°F.
If using the heavy cream option, stir the lemon juice or vinegar into the cream and let sit for 5 minutes.
In a medium bowl, whisk together the all-purpose flour, white whole wheat flour, sugar, baking powder, baking soda, salt, raisins, and orange zest.
In a separate bowl or measuring jug, whisk together the egg, sourdough starter, chosen dairy option, and melted butter until smooth.
Add the wet ingredients to the dry ingredients and mix just until combined. Do not overmix. The batter should be thick but scoopable. If it feels overly stiff, add 1–2 tablespoons additional dairy.
Choose your bake method below:
Muffin Method
Line a 12-cup muffin pan with paper liners. Divide the batter evenly among the muffin cups. Bake for 30–35 minutes, until golden and a skewer inserted into the center comes out clean. Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Loaf Method
Grease a 9 x 5–inch loaf pan. Transfer the batter to the prepared pan and smooth the top. Optional: score a shallow slit down the center of the loaf. Bake for 50–60 minutes. If the top browns too quickly, tent loosely with foil. The loaf is done when a skewer inserted into the center comes out clean and the loaf sounds hollow when tapped. Cool in the pan for 10–15 minutes, then turn out onto a wire rack to cool completely before slicing.
