How to Make Easy Sourdough Pumpkin Pecan Muffins

Hey friends! Welcome back to The Midnight Mustard Seed! I’m so glad you’re here. There’s something so cozy about this time of year when the air turns crisp and that warm pumpkin flavor start calling my name. Last night, I was batch making our breakfast. With a jar full of sourdough starter in the fridge (you know how that goes!), I decided it was the perfect moment to bake up something using the discard. These easy sourdough pumpkin pecan muffins (or sourdough pumpkin mini muffins if you go the mini route) are so tender and full of that classic pumpkin spice flavor—definitely a kid-approved snack and one of our most requested fall sourdough recipes around here! 

I’m all about using simple ingredients and making things approachable, especially when it comes to baking with my own sourdough starter. The addition of sourdough discard brings some wonderful health benefits and adds a subtle tang that pairs perfectly with the pumpkin. These are a great way to use up a lot of discard without an excess amount of sugar as well. I’m always watching the sugar we intake because it can cause inflammation. In my recipes, I often sub golden monk fruit for sugar- cup for cup.

This recipe is super forgiving, whether you’re feeding your homemade sourdough starter regularly or just working with discard that you neglect at times (like I do). They can be made as standard size muffins or easy mini muffins for little hands (or quick grab-and-go snacks!). Let’s get into it and make some good things together!

Easy Sourdough Pumpkin Pecan Muffins

Yield: About 12 standard muffins or 24 mini muffins

Prep time: 15 minutes

Bake time: 18-22 minutes (standard) or 12-15 minutes (mini)

Ingredients

For the muffins:

•  ½ cup + 2 Tbsp flour 

•  ¼ cup sourdough discard (unfed, straight from the fridge is fine—room temperature if you have time)

•  1 tsp baking powder

•  ½ tsp baking soda

•  ½ tsp sea salt

•  ½ cup golden monk fruit sweetener (or your preferred granulated sugar substitute for a lighter sweetness)

•  ½ cup brown sugar (for that rich, caramel-like depth. )

•  ¼ tsp ground nutmeg

•  1 ½ tsp pumpkin pie spice (or cinnamon if you like it simpler—warm spices make all the difference!)

•  2 large eggs

•  1 tsp vanilla extract

•  1 cup pumpkin puree (canned or homemade; not pumpkin pie filling)

•  ½ cup neutral oil (like avocado or canola; or melted coconut oil for a fun twist. Butter is fine too.)

•  Optional add-ins: ½-1 cup chocolate chips (melty chocolate chips turn these into a version of Little Debbies or sourdough chocolate mini muffins—yum!)

For the crumble topping (streusel topping):

•  ⅓ cup flour (all-purpose or whole wheat pastry)

•  ⅓ cup brown sugar

•  1 tsp cinnamon

•  ⅓ cup unsalted butter, softened (or cold butter cut in for extra crunch)

•  ½ cup chopped pecans (plus extra for sprinkling on top)

Instructions

1.  Preheat your oven to 350°F (175°C). Line your muffin tin or muffin pan with paper liners (or grease well if skipping them). This makes cleanup a breeze!

2.  In a large mixing bowl, whisk together the dry ingredients: the flour, baking powder, baking soda, salt, golden monk fruit, brown sugar, nutmeg, and pumpkin pie spice.

3.  In a separate bowl, mix the wet ingredients: eggs, vanilla extract, pumpkin puree, neutral oil (or melted butter if you prefer), and the sourdough discard. Stir until smooth—the lactic acid from the discard helps create that tender crumb and moist crumb we all love.

4.  Pour the wet ingredients into the dry ingredients. Gently fold with a spatula or wooden spoon until just combined. Don’t overmix—this keeps the fluffy texture! If adding chocolate chips or extra pecans, fold them in now.

5.  For the crumble topping: In a small bowl, mix the flour, brown sugar, cinnamon, and softened butter (or cold butter cubed in) until it forms crumbly bits. Stir in the chopped pecans.

6.  Scoop the muffin batter into the prepared muffin cups—fill about ¾ full for standard size or just right for minis. Sprinkle generously with the streusel topping and a few extra pecans for that perfect crunch.

7.  Bake until a toothpick inserted in the center comes out clean: 18-22 minutes for standard muffins, 12-15 for minis. Your kitchen will smell incredible!

8.  Let cool in the pan for a few minutes, then transfer to a wire rack.

These have the best tender crumb—moist without being dense—and that pumpkin spice flavor shines through. Store in an airtight container for up to 3 days, or pop them in a freezer bag (single layer to avoid sticking) for longer. They thaw beautifully and make an easy snack or breakfast!

These pumpkin sourdough muffins (or sourdough discard pumpkin muffins) are one of those great recipes that feel special but use mostly pantry staples. Whether you’re new to baking with discard or have a thriving starter, they’re a perfect way to enjoy those cozy fall flavors .
