Sourdough Pumpkin Muffins (Easy Discard Recipe)

Sourdough Pumpkin Muffins are soft, warmly spiced muffins made with pumpkin purée, sourdough discard, almond flour, and a gluten-free flour blend. They bake in about 35 minutes and make an easy fall breakfast, snack, or simple dessert. This version uses cold, unfed sourdough discard for a subtle tang, coconut sugar for caramel-like sweetness, and a crunchy sugar top for extra texture.

Fall is hands-down my favorite season, even when September still feels like summer here in Texas. The second I notice that little shift in the air, I'm ready to pull out the pumpkin, cinnamon, and sourdough discard and start baking again.

These Sourdough Pumpkin Muffins are always one of the first things I make. They're warmly spiced and just sweet enough, but what really sets them apart for me is the sourdough discard. A lot of bakers use discard mainly to keep it from going to waste, but I've always loved it for the flavor. That subtle tang balances the pumpkin pie spice and coconut sugar so the muffins don't taste overly sweet.

I've been baking with sourdough discard for years, and muffins are still one of my favorite ways to use it. For this recipe, I use almond flour and a gluten-free flour blend along with my regular wheat-based sourdough discard. That combination gives the muffins a soft, cakey texture without feeling heavy or dry.

I first made these after testing another fall recipe and ending up with extra pumpkin purée and sourdough discard in the fridge. You know what? Sometimes those random kitchen leftovers turn into the recipes you keep making year after year. These have been part of my fall baking routine ever since.

Ingredients You'll Need

• Gluten-Free Flour Blend: This gives the muffins structure and helps them hold their shape without feeling dense. I use either King Arthur Measure-for-Measure or Bob's Red Mill 1:1 Baking Flour; both have a great balance of rice flour and starches that mimic the texture of regular all-purpose flour. After years of gluten-free baking, these are the blends I trust most for consistent, tender muffins. If you prefer regular flour, all-purpose flour can be substituted 1:1 with no other changes to the recipe.
• Almond Flour: I always go for super-fine almond flour (Bob's Red Mill is my go-to). It adds natural moisture, healthy fats, and a chewy texture that makes these muffins feel satisfying, not crumbly or dry. The mild nutty flavor also plays really well with pumpkin and warm spices. 
• Sea Salt: Just a small amount goes a long way in balancing the sweetness and enhancing all the cozy flavors. I always recommend fine sea salt in baking for more even distribution, especially in a batter like this, where you don't want pockets of salt. 
• Baking Powder: Since this batter is a bit heavier (thanks to the pumpkin and almond flour), you'll need a reliable lift. Baking powder helps these muffins rise into soft, fluffy domes. Just make sure it's fresh, as expired leavening is one of the most common reasons baked goods fall flat. 
• Pumpkin Pie Spice: This is what gives these muffins that unmistakable fall flavor. I use Simply Organic pumpkin pie spice, but you can make your own by combining a blend of cinnamon, ginger, nutmeg, and cloves. The spice levels are balanced enough to shine through without overpowering the pumpkin.
• Unsalted Butter: Butter gives these muffins richness and helps create a tender crumb. I use Kerrygold grass-fed butter whenever possible. The flavor is unmatched and adds depth to the base of the batter, especially when creamed with coconut sugar. 
• Coconut Sugar: My favorite unrefined sweetener for baking. It brings a subtle caramel-like flavor that works beautifully with the pumpkin and spice.
• Eggs: These add structure, moisture, and help bind the batter together. I always recommend using room-temperature eggs for even mixing. Cold eggs can make the butter seize up. 
• Sourdough Discard: This is one of my favorite ways to use up leftover discard. I always keep some stored in the fridge from weekly feedings. It doesn't make the muffins taste sour, but it does add depth, balance the sweetness, and give just a hint of tang. It's one of the easiest places to let sourdough flavor shine without any fuss. 
• Pumpkin Purée: Use 100% canned pumpkin, not pumpkin pie filling. The purée gives the muffins moisture, natural sweetness, and that earthy flavor that makes pumpkin bakes feel like fall. 
• Vanilla Bean Paste: This adds a deeper, richer vanilla flavor than extract. It's a small upgrade, but one I think makes a difference, especially when paired with warming spices. If you don't have it, good-quality vanilla extract works too. 
• Coconut Sugar or Turbinado Sugar (for topping): This part is optional, but worth it. Sprinkling a little sugar on top before baking gives each muffin a light crunch that contrasts beautifully with the soft center. It's that little finishing touch that makes them feel bakery-worthy.

How To Make Sourdough Discard Pumpkin Muffins

This is an overview with step-by-step photos. Full ingredients & instructions are in the recipe card below.

Step 1. Preheat your oven to 350°F and line a muffin pan with parchment paper liners.

Step 2. In a medium bowl, whisk together the gluten-free flour, almond flour, sea salt, baking powder, and pumpkin pie spice until well combined.

Step 3. In the bowl of a stand mixer fitted with the paddle attachment, add the butter and coconut sugar. Mix on medium speed until light and fluffy.

Step 4. Add the eggs, sourdough discard, pumpkin purée, and vanilla bean paste to the butter mixture. Mix again until fully combined.

Step 5. Slowly add the dry ingredients to the wet, mixing on low speed until just combined. Avoid overmixing to keep the muffins tender.

Step 6. Use a cookie scoop to portion the batter into the prepared muffin liners. Fill each about ¾ full. Sprinkle a pinch of coconut sugar or turbinado sugar on top of each muffin.

Step 7. Bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean and the tops are golden and slightly firm.

Storage And Reheating

• Room Temperature: Keep them in an airtight container on the counter for up to 3 days. I like to line the bottom with a paper towel to catch any extra moisture and keep the texture just right. 
• Refrigerator: They'll stay fresh in the fridge for up to a week. Just let one come to room temperature before eating.
• Freezing: These freeze like a dream. Wrap them up individually and stash them in a freezer-safe bag; they'll keep for up to 2 months. When you're ready, thaw overnight or warm in a 300°F oven for 5 to 8 minutes until soft and steamy.
