Sourdough Discard Whole Wheat Pumpkin Bread

pumpkin bread with sourdough discard

This sourdough discard whole wheat pumpkin bread recipe was adapted from Cookie and Kate’s Healthy Pumpkin Bread recipe. Cookie and Kate is one of my favorite food blogs because all of her recipes are foolproof (I make one probably about once per week) and she even offers variations for various dietary restrictions. I like this pumpkin bread because it is not super sweet. The loaf is light and not overwhelmingly sugary.

Substitution of Sourdough Discard for Whole Wheat Flour

This recipe uses all whole wheat flour, which is great because that is straightforward to swap for sourdough starter. To adapt this recipe to include sourdough discard, I removed the water/milk in the original recipe and decreased the flour to account for the addition of sourdough starter. My sourdough starter is 100% hydration, which means it is about 50% flour and 50% water by weight.

Ingredients and Equipment Notes

Note: As an Amazon Associate I earn from qualifying purchases from links in this post.

For this recipe, I used Trader Joe’s canned pumpkin purée, but any pumpkin purée should work well. I also used California Extra Virgin olive oil and white whole wheat flour.

Also, I would highly recommend using real maple syrup (not the artificial maple flavored syrup).

You’ll also need a 9×5 inch loaf pan, a whisk and a spatula. I really like these GIR brand spatulas lately because they don’t melt easily. They come in a variety of sizes and really hold up well. All of my other spatulas have melted on the stove eventually.

I used the pumpkin spice mix from Trader Joe’s but you could also make your own by mixing your own (approximately 1/2 teaspoon cinnamon, 1/2 teaspoon ground ginger, 1/4 teaspoon ground nutmeg, 1/4 teaspoon ground cardamom, 1/4 teaspoon ground cloves).

I hope you enjoy this sourdough discard whole wheat pumpkin bread! If you are looking for other other recipes for your sourdough discard, check out these breadsticks!

  1. I was about to try this recipe but noticed you talk about the pumpkin pie spice in the Ingredients and Equipment notes but not in the recipe. I’m assuming it is added with the baking soda, etc. Please clarify.

    1. Hi Mary, thanks for noticing that! good catch! I just updated the recipe to include the pumpkin pie spice. Also thanks for reminding me about this recipe. I need to make it again soon!
