These pumpkin dark chocolate sourdough cookies are chewy, rich, and full of warm fall flavor. Made with cooked down pumpkin and a mix of chocolate chunks, they bake up thick and fudgy and get even better by the next day. Using 100% freshly milled hard red wheat flour, make these cookies nourishing and delicious!

There’s something about the mix of pumpkin, sourdough, and dark chocolate that feels like pure autumn comfort. These cookies are soft and decadent, with just the right hint of spice and a deep, almost caramel-like flavor from the cooked-down pumpkin. The freshly milled flour gives them a hearty texture that still melts in your mouth, and the sourdough adds that subtle tang that balances it all out.
If you want to start milling your own flour, I really do love this NutriMill. Freshly milled flour makes such a big difference in both texture and flavor, and you get all the nutritional benefits that store bought flour loses. It’s one of those upgrades that feels intimidating at first but ends up being totally worth it.
How I Make It
I start by cooking down the pumpkin, and that step makes all the difference. I melt the butter, stir in the pumpkin and spices, and cook it until it gets thick, darker, and really concentrated. You can’t walk away during this part because it goes fast, but once it tightens up I let it cool completely.

For the dough, I cream the butter and sugars until they’re fluffy, then mix in the egg, yolk, vanilla, sourdough starter, and that cooled pumpkin. The batter always turns out so glossy and pretty at this point. I whisk the flour, baking soda, and salt, fold it in gently, and then add a mix of chocolate chunks and chips so every cookie has those big melty pockets.

I like to chill the dough for at least two hours, but honestly it’s even better the next day. The sourdough flavor develops, and the cookies bake up thicker and richer. When I’m ready to bake, I scoop big portions and bake them for 13 minutes so the centers stay soft. When the batter is cold it can be hard to scoop, so you may ant to let it sit on the counter for 30 minutes before scooping. I like to use a large cookie scoop for this.

As soon as they come out, I sprinkle a little flaky salt and gently press the tops to keep them nice and fudgy. They finish setting as they cool on the pan, and by the next day they’re even more flavorful. They turn out decadent with just enough pumpkin spice, and the texture is everything I want in a fall cookie.

This is quite possibly the best cookie I’ve ever had! Thank you so much for this wonderful, creative recipe!
I’m so happy to hear that! Thanks for your comment!
Hi! If I am using whole wheat flour from the store, how many grams of that and water should I use? I am still learning on how to adjust things for the recipes that call for freshly milled, but I need to make these for a party on friday and dont want to mess it up. Thank you in advance!
Hi! I would still follow the recipe exactly and then add a little splash of milk if it looks too dry or a little more flour if it looks too wet.
