Soft, spiced, and perfectly chewy, these Sourdough Pumpkin Snickerdoodles combine the cozy flavors of pumpkin pie with the tangy goodness of sourdough. They’re the ultimate fall cookie — perfect for using up sourdough discard and filling your kitchen with warm, autumn aromas.
Start by creaming together softened butter and sugar. The butter and sugar should be pale and creamy and completely dissolved into each other with no grittiness. Now add the pumpkin puree, sourdough starter and vanilla and beat until well combined.
Now, on top of the wet ingredients, add the flour, salt, pumpkin pie spice, baking soda & cream of tartar. Mix thoroughly until well combined.
Cover the pumpkin sourdough snickerdoodle dough and refrigerate for at least an hour (you can leave the dough in the fridge for up to 3 days with no issues).
When you're ready to bake them, preheat your oven to 375F (190C).
Mix the sugar and pumpkin pie spice for the topping together in a small bowl.
Line 2 cookie sheets with parchment paper. Roll the snickerdoodle dough into small ball (around 1 tablespoon dough). Roll each ball into the bowl of spiced sugar and place onto the cookie sheets allowing plenty of space around them.
Bake the pumpkin sourdough snickerdoodles for 10 minutes at 375F (190C). They will be soft and slightly under baked when you take them out.
Allow them to rest on the tray for 10 minutes before removing and placing on a wire rack to fully cool.
