Sourdough Shortbread Cookies

Shortbread cookies are an under-appreciated cookie but are so delicious and easy to make. My sourdough shortbread cookies strike a perfect balance of sweet and buttery flavors and have a unique sourdough twist. Combined with a delightfully crumbly texture and crisp golden edges, this buttery cookie recipe is sure to be a hit.

Why You Will Love these Sourdough Shortbread Cookies

Sourdough shortbread cookies are easy to make. This simple recipe requires only a few pantry staple ingredients you probably already have. These buttery shortbread cookies are a great recipe to have on hand as they can be made into several different variations. I used this base recipe for several of my other sourdough cookie recipes, including my sourdough thumbprint cookies, my maple pecan sourdough shortbread cookies, and my sourdough dark chocolate chocolate orange shortbread cookies (the hint of orange zest flavor in these cookies is so good!). 

How to Use Sourdough Starter in Shortbread Cookies

The key to making good shortbread cookies with sourdough starter is not adding too much liquid. Liquid causes cookies to spread and become puffy, which is not the texture we want to achieve with shortbread cookies. 

This recipe requires no eggs and and the only liquid comes from the starter and the small amount of vanilla extract. The result is delightfully crumbly and buttery cookies you expect from a perfect classic shortbread cookie.

Ingredients and Substitutions

  • Butter: This recipe calls for unsalted butter but you can also use salted butter if that is what you have on hand. 
  • Sugar
  • Sourdough starter: Use 100% hydration starter for this recipe. It can be active sourdough starter or sourdough discard straight from the fridge.
  • Vanilla
  • Salt
  • Flour: This recipe uses all purpose flour but you can also use bread flour if desired. 
  • Optional variation: If you want to give these sourdough discard shortbread cookies a little bit of extra flavor, you can add lemon zest (about the zest from 1 lemon) to the recipe. This will brighten the flavors of the cookies and is a great variation for the spring time. 

A Little Bit of Science

You will notice that there is no leavening agent (like baking soda or baking powder) in these cookies. We actually do not want the cookies to rise or spread for the optimal texture so we avoid these ingredients in this recipe. 

How to Make Sourdough Discard Shortbread Cookies

Step 1: Mix the butter and sugar in the bowl of a stand mixer on medium speed. If you do not have a stand mixer you can mix these by hand or use a hand mixer.

Alternative Shaping Options

If you want to make your shortbread cookies more festive, you can roll out the dough until it is 1/3 inch thick and use your favorite cookie cutters to create fun shapes. This is fun and festive around the holidays. You can use a heart-shaped cookie cutter around Valentine’s Day (also check out my sourdough strawberry cinnamon roll recipe) or use Christmas cookie cutters to create a cute Christmas cookie tray or holiday cookie box. 

Step 6: Chill for 1 hour. 

Step 7: Slice into 1/3 inch cookies and place on a cookie sheet lined with parchment paper.

Step 8: Bake for 12-15 minutes. The edges should start to turn golden brown when done. Allow to cool completely on a wire rack.

How to Make Ahead

These delicious cookies can easily be made ahead of time. There are two ways to do this: 

  1. You can freeze the baked cookies in a gallon freezer safe bag.
  2. Cut the log of cookie dough in half after you roll it in the sugar. Wrap each half in plastic wrap and place in a gallon freezer bag. Store in the freezer until ready to use. Allow the dough to defrost in the fridge several hours before you are ready to bake so you can easily slice them. 

How to Store 

Store these sourdough cookies in an airtight container such as a gallon ziplock bag, a storage container, or on a plate covered with plastic wrap. These cookies are best enjoyed within 3-4 days but will last up to a week at room temperature.
