Tasty Sourdough Pumpkin Cookies

If you ask me, sourdough pumpkin cookies are the perfect fall treat.

These soft, chewy cookies bring together the tangy flavor of sourdough starter with warm pumpkin and cozy spices. The sourdough adds a slight tang that balances out the sweetness perfectly.

They’re made with real pumpkin puree and a blend of cinnamon, nutmeg, and ginger that fills your kitchen with the best autumn smells. The sourdough starter also gives them a tender texture that’s just a little different from regular cookies.

They’re a great way to use up extra sourdough starter, and they taste like fall in every bite.

What Kind of Pumpkin Puree Should I Use?

For these sourdough pumpkin cookies, you can use either canned pumpkin puree or make your own from scratch – both work great. If you’re going the canned route, make sure to grab plain pumpkin puree and not pumpkin pie filling, which already has spices added that could throw off your cookie’s flavor balance. Homemade pumpkin puree from sugar pumpkins or pie pumpkins will give you a slightly more intense pumpkin flavor, but honestly, the good quality canned stuff is convenient and tastes just as good. Just make sure your pumpkin puree isn’t too watery – if it seems really wet, you can drain it on paper towels for about 15 minutes before using it in your dough.

Options for Substitutions

These cookies are pretty forgiving when it comes to swaps, so here’s what you can change up:

• Sourdough starter: This is really what makes these cookies special, so I’d recommend keeping it if possible. But if you don’t have any, you can substitute with an equal amount of Greek yogurt or sour cream for that tangy flavor.
• Pumpkin puree: Sweet potato puree works great as a 1:1 swap, or you can try butternut squash puree. Just make sure it’s not pumpkin pie filling, which has added spices and sugar.
• Brown sugar: You can use all white sugar if that’s what you have, though you’ll lose some of that molasses depth. Or try coconut sugar for a slightly different flavor.
• Spices: Don’t have all the individual spices? Use 2 teaspoons of pumpkin pie spice instead of the cinnamon, nutmeg, ginger, and cloves.
• Maple syrup in glaze: Honey works as a substitute, but start with less since it’s sweeter than maple syrup. You could also use corn syrup for a more neutral flavor.
• All purpose flour: You can substitute up to half the flour with whole wheat flour for a nuttier taste, but don’t go beyond that or your cookies might get too dense.

Watch Out for These Mistakes While Baking

The biggest mistake with sourdough pumpkin cookies is using too much liquid from wet ingredients like pumpkin puree or an overly active sourdough starter, which can make your cookies spread too much and turn out flat – make sure your pumpkin puree is well-drained and your starter isn’t too liquidy.

Another common error is not chilling the dough for at least 30 minutes before baking, as the high moisture content means these cookies need that extra time to firm up and hold their shape in the oven.

Don’t overbake these cookies either – they should look slightly underdone when you pull them out since they’ll continue cooking on the hot pan, and the centers should still be soft to the touch.

For the maple glaze, let the cookies cool completely before glazing, otherwise the warm cookies will cause the glaze to melt right off instead of setting into that perfect sweet coating.

What to Serve With Sourdough Pumpkin Cookies?

These soft, spiced cookies are perfect with a warm cup of coffee or chai tea – the maple glaze pairs beautifully with those cozy fall flavors. I love serving them alongside a glass of cold milk for dunking, especially when they’re still slightly warm from the oven. They also make a great dessert after a hearty fall meal, or you can pack them up as a sweet treat for picnics and potlucks. For an extra special touch, try serving them with a scoop of vanilla ice cream or a dollop of whipped cream for a simple but satisfying dessert.

Storage Instructions

Store: These soft pumpkin cookies stay fresh for about a week when stored in an airtight container at room temperature. If you glazed them, make sure the glaze is completely set before stacking, or use parchment paper between layers to prevent sticking.

Freeze: You can freeze the baked cookies for up to 3 months in a freezer-safe container or bag. I like to freeze them before adding the glaze, then thaw and glaze them when I’m ready to serve. The dough also freezes well – just scoop it into balls and freeze on a baking sheet, then transfer to a bag.

Make Ahead: The cookie dough can be made up to 2 days ahead and kept covered in the fridge. Cold dough actually bakes up a bit thicker, which I love! You can also prepare the maple glaze a day early and store it covered at room temperature – just give it a quick stir before using.

Ingredients

For the cookies:

• 150 g granulated sugar
• 115 g unsalted butter, room temperature (I use Kerrygold for richness)
• 2 g fine salt
• 1 large egg (room temperature for better mixing)
• 5 g vanilla extract
• 200 g pumpkin puree (I use Libby’s)
• 100 g active sourdough starter (fed 4-8 hours prior)
• 1 tsp ground cinnamon (freshly ground preferred)
• 5 g baking powder
• 1/2 tsp ground nutmeg
• 100 g brown sugar (packed lightly)
• 1/4 tsp ground cloves
• 1/2 tsp ground ginger
• 400 g all-purpose flour (sifted to remove lumps)
• 6 g baking soda

For the maple glaze:

• 20 g soft unsalted butter
• 5 g vanilla extract
• 120 g confectioners’ sugar (sifted to prevent lumps)
• 70 g pure maple syrup (for authentic flavor)
• 1/2 tsp ground cinnamon

Step 1: Prepare Mise en Place and Cream the Butter Mixture

• 115 g unsalted butter, room temperature
• 150 g granulated sugar
• 100 g brown sugar
• 1 large egg

Gather all ingredients and ensure the butter and egg are at room temperature—this helps them incorporate smoothly and create a lighter, fluffier dough.

In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar for 2-3 minutes until the mixture is pale and fluffy.

This creaming process incorporates air, which helps the cookies rise.

Add the room-temperature egg and beat until fully combined, scraping down the bowl as needed.

Step 2: Incorporate Sourdough, Pumpkin, and Vanilla

• 100 g active sourdough starter
• 200 g pumpkin puree
• 5 g vanilla extract

Add the fed sourdough starter, pumpkin puree, and vanilla extract to the creamed butter mixture.

Whisk vigorously for 30-45 seconds until the mixture is completely smooth and well-combined.

The sourdough starter adds subtle tang and complexity, while the pumpkin creates moisture and binding structure.

Make sure there are no streaks of pumpkin or starter visible.

Step 3: Mix Dry Ingredients and Create the Dough

• 400 g all-purpose flour
• 6 g baking soda
• 5 g baking powder
• 1 tsp ground cinnamon
• 1/2 tsp ground nutmeg
• 1/2 tsp ground ginger
• 1/4 tsp ground cloves
• 2 g fine salt

In a separate medium bowl, whisk together the sifted flour, baking soda, baking powder, cinnamon, nutmeg, ginger, cloves, and salt.

I like to use freshly ground spices here because they have so much more intensity than pre-ground—you really taste the warmth of the cinnamon and nutmeg.

Gently fold the dry mixture into the wet ingredients from Step 2 using a spatula or wooden spoon until just combined.

Don’t overmix; stop folding as soon as no streaks of flour remain.

Step 4: Chill the Dough

• dough from Step 3

Cover the dough bowl with plastic wrap or a lid and refrigerate for at least 2 hours.

This resting period allows the flour to fully hydrate, the flavors to develop, and makes the dough much easier to scoop without spreading.

I often chill mine overnight because the flavor becomes even better and the cookies bake more evenly.

Step 5: Bake the Cookies

• chilled dough from Step 4

Preheat your oven to 190°C (375°F) and line two baking trays with parchment paper.

Remove the chilled dough from the refrigerator and scoop into 25g balls using a cookie scoop or tablespoon measure, spacing them about 2 inches apart on the prepared trays.

Bake for 13-15 minutes, until the edges are set and lightly golden but the centers still look slightly underbaked—they’ll continue to cook as they cool.

The cookies should be tender with crispy edges, not completely firm.

Step 6: Cool the Cookies

Let the baked cookies rest on the baking trays for 10 minutes to set their structure.

This prevents them from breaking apart when transferred.

Then move them to a wire cooling rack to cool completely before glazing—about 30 minutes total.

This ensures the glaze won’t melt off.

Step 7: Prepare Maple Glaze and Finish

• 120 g confectioners’ sugar
• 20 g soft unsalted butter
• 70 g pure maple syrup
• 5 g vanilla extract
• 1/2 tsp ground cinnamon

While the cookies cool, make the glaze by whisking together the sifted confectioners’ sugar, soft butter, pure maple syrup, vanilla extract, and ground cinnamon in a small bowl until smooth and drizzle-able.

Drizzle the glaze over the fully cooled cookies in thin lines or patterns.

The maple adds an authentic autumn note that complements the pumpkin spices beautifully.
