Irresistibly Chewy Sourdough Molasses Cookies (Perfectly Spiced!)

The first time I made these cookies, it felt like stepping back in time. My grandmother used to bake molasses cookies every holiday season, filling the house with the irresistible aroma of cinnamon, ginger, and caramelized molasses.

But adding sourdough starter to the mix? That was my personal experiment—one that turned out to be a delicious success.

Freshly baked sourdough molasses cookies sprinkled with powdered sugar on a ceramic plate. The plate is surrounded by cinnamon and a bowl of powdered sugar.

This recipe marries the warmth of traditional molasses cookies with the slight tang of sourdough, creating a cookie that’s rich, chewy, and deeply flavorful.

Step-by-Step Instructions

Preheat the oven: Set oven to 350°F (175°C) and line a baking sheet with parchment paper.
Mix wet ingredients together: Cream the butter and sugars in a large bowl until light and fluffy. Add molasses, eggs, and sourdough discard to the butter-sugar mixture, mixing until smooth.
Prepare dry ingredients: In a separate bowl, whisk together the flour, baking soda, spices, salt (and black pepper if using).
Combine wet and dry ingredients: Gradually add the dry ingredients to the wet mixture, stirring until just incorporated.
Chill the dough: In a refrigerator, chill the mixture for at least 30 minutes to enhance flavor and texture.
Roll the dough: Roll the mixture into tablespoon-sized balls, then coat in granulated sugar or a cinnamon-sugar mix (optional).
Bake: Place dough balls on the baking sheet, leaving space between each. Bake for 10-12 minutes until edges are set but centers are slightly soft.
Cool the cookies: Cool on the baking sheet for 5 minutes before transferring to a wire rack.

Expert Tips for the Best Cookies

Don’t skip the chilling step – It helps the cookies maintain their shape and intensifies the flavors.
Use fresh spices – If your ground ginger or cinnamon has been in the pantry for years, replace them for a more vibrant taste.
Sprinkle with coarse sugar before baking for a subtle crunch and sparkle.
For extra chewiness, slightly underbake the cookies and let them finish setting as they cool.
Store in an airtight container to keep them soft for days.

FAQs About Sourdough Molasses Cookies

Can I use fed sourdough starter instead of discard?
Yes, but the flavor will be less tangy. Using discard enhances the sourdough notes.

Can I freeze the dough?
Yes! Scoop dough balls onto a tray, freeze until solid, then store in a sealed container. Bake from frozen, adding 1-2 extra minutes.

How do I make these cookies even softer?
Store them with a slice of bread in an airtight container—the cookies will absorb the moisture and stay tender.

Can I use blackstrap molasses?
Blackstrap molasses is more bitter and less sweet than regular molasses, so use it cautiously or mix it with a milder molasses.
