You’ll love the taste and texture of these Sourdough Molasses Cookies. Molasses and sourdough are a match made in cookie heaven! Perfectly spiced, seriously chewy with a crunchy, crackly top, these cookies develop an even more delicious texture days after being baked, which makes them perfect for gift-giving!

These cookies are another collaboration with my baking bestie Mimi Council. Mimi founded the very first organic bakery in the United States, which specialized in cookies when they first opened. So when we decided to collaborate, I knew I had to ask her to create a cookie recipe that would take full advantage of the unique qualities of sourdough discard. These cookies were it!

What Makes Sourdough Molasses Cookies Unique?
Sourdough Molasses Cookies are coated in cane sugar before being baked, this results in cookies with a crackly and crunchy crust. The addition of molasses creates an incredibly sweet and chewy texture. These cookies taste incredible fresh out of the oven, but their texture really transforms once they are fully cooled. They are even better days after being baked, becoming even chewier, almost candy-like and seriously delicious.

Five spice adds a kick to these cookies and makes them different from regular spice cookies. We usually keep whole spices at home, so I created my own five spice mix using cinnamon, star anise, szechuan peppercorns, cloves and fennel seeds. This combination of spices imparts a delicious warmth, a little spice and notes of licorice to these cookies. I include the recipe for my five spice mix here, but you can totally use your favorite store-bought brand.
Baking with Sourdough Discard
Sourdough discard adds a great tangy flavor that balances the rich sweetness of molasses. Since you are not using it to make bread, your sourdough starter does not need to be activated or fed for it to work in this recipe and you can use it directly from the fridge. Older discard will have a tangier, more acidic flavor than freshly-fed sourdough starter. Both will work for this recipe, you’ll get a slightly different result but your cookies will still be delicious!

Cookie Ingredients
Unsalted butter: Binds the ingredients, imparts richness and tenderizes these cookies. Mimi’s original recipe uses salted butter, but I wanted to test this recipe with unsalted butter as well since it's what most bakers have at home. I added a little bit more salt to my cookies and they ended up delicious. Salted butter does add a delicious flavor so, use it if you have it.
Cane sugar: Imparts sweetness and gives these cookies their characteristic crackly and crunchy exterior.
Dark brown sugar: Imparts sweetness and heightens the flavor of molasses.
Blackstrap molasses: Adds a rich flavor, sweetness and wonderful chewiness to these cookies.
Vanilla extract: Adds a floral flavor.
Sourdough discard: Imparts a delicious tang that balances the rich sweetness of molasses.
All purpose flour: The low protein content of all-purpose flour imparts tenderness while helping these cookies maintain their chewy structure
Chinese five spice: Makes these cookies so unique, imparts warmth, heat and a note of licorice. You can make your own or use store-bought.
Fine sea salt: Enhances the flavors of the rest of the ingredients
Baking soda: Leavens these cookies to create a light and chewy texture.

Frequently Asked Questions
The prominent flavor in this cookies is five spice. The tang of sourdough really compliments the sweetness and strong flavor of molasses.
Absolutely! You can make this dough the night before you want to bake your cookies. Portion your cookie dough out and chill on a cookie sheet, but wait to coat your dough in sugar right before baking.
Freezing Instructions: For even longer storage, portion out your cookie dough and place the balls on a small baking sheet (no need to space them out). Freeze the tray uncovered, for 1 hour, once completely frozen, move the cookie dough to a ziplock bag and store for up to 3 month. Bake frozen cookie dough at 375 F for 12 to 15 minutes.
These cookies last up to a week stored in an airtight container at room temperature. While they taste amazing fresh out of the oven, they taste even better a few days after being baked. They develop a really nice and chewy texture but keep their crunchy texture thanks to the cane sugar coating.
Absolutely! Simply use the same proportion of freshly fed sourdough starter in the recipe. Your starter won’t add a strong tangy flavor to your cookies, but will still work.
If you don’t have a starter, but still want to try out this recipe, simply add 28 grams of all-purpose flour and 28 grams of water to your dough. The recipe will still turn out delicious, but you won’t have the tangy flavor of sourdough.
Yes! You can use your discard directly from the refrigerator for this recipe. Since you won’t be using it as a leavener, your starter does not need to be fed or activated for it to work.
