How to Make Sourdough Linzer Cookies
-
Preheat the oven to 350°F (175°C). A hot oven is essential for achieving perfectly baked cookies with a golden edge and tender center.
-
Mix in a medium bowl the gluten-free flour, xanthan gum, and salt; set aside. This blend forms the base of your cookies and ensures a consistent texture.
-
Cream together the softened butter, caster sugar, egg, sourdough starter discard, and vanilla extract in a large bowl. Blend them until smooth and creamy, releasing a rich aroma.
-
Combine the flour mixture gradually with the butter mixture, using your hands to form a dough. Avoid electric mixers here; using your hands keeps the dough pillowy soft and undermixed.
-
Roll out the dough on a floured surface to about ¼ inch thick. Ensure it’s not too thin, as you want your cookies to have that inviting bite.
-
Cut out cookie shapes; make sure the tops and bottoms match perfectly. Use a smaller cutter to create centers for half of them, leaving room for a jam filling.
-
Transfer the cutouts to a lined baking sheet, leaving minimal space in between. This helps cookies to bake evenly without spreading too much.
-
Bake for 9-11 minutes until the edges start to turn slightly golden. Cool them briefly on the tray before moving to wire racks to ensure they hold their shape.
-
Dust the tops with powdered sugar and spread jam on the bottoms of half the cookies before sandwiching them together. This step adds sweetness and a vibrant pop of color.
-
Rest the assembled cookies for 12 hours before serving. This allows the flavors to meld and the texture to soften beautifully.
Optional: Sprinkle with extra powdered sugar just before serving for an elegant touch.

Expert Tips for Sourdough Linzer Cookies
-
Mix by Hand: Avoid using an electric mixer to keep the dough pliable, preventing overmixing and ensuring a delightful texture in your sourdough Linzer cookies.
-
Flour Generously: When rolling out the dough, sprinkle enough gluten-free flour to prevent sticking. This creates a smooth surface and keeps the cookies intact.
-
Consistent Thickness: Roll the dough to about ¼ inch thick; too thin will result in crispy cookies, while too thick will lead to undercooked centers.
-
Quality Jam: Opt for quality jam for filling; homemade or artisanal preserves will enhance the flavor and make each bite memorable.
-
Rest Time: Don’t skip the resting period of 12 hours; this step is crucial for achieving the optimal texture and softening the cookies further.
-
Storage Care: Store cookies in a single layer to maintain shape; stacking can lead to squished cookies and an unwanted texture.

Sourdough Linzer Cookies Recipe FAQs
How do I choose the best gluten-free flour for these cookies?
For the best results, look for a gluten-free flour blend that’s made with a combination of different flours, including sorghum and rice flour, along with a good starch like potato, corn, or tapioca. I recommend a mix of 25% sorghum, 25% rice flour, and 50% starch for optimal texture. This combination will give you that delightful crumbly yet tender bite, characteristic of traditional Linzer cookies.
What’s the best way to store Sourdough Linzer Cookies?
You can store your Sourdough Linzer Cookies in an airtight container at room temperature for up to 3 days. To maintain their delicious texture, make sure they are not stacked, as this can cause them to squish and lose shape. Alternatively, they can be refrigerated for up to 1 week.
Can I freeze Sourdough Linzer Cookies?
Absolutely! For the best experience, freeze the unassembled cookies. Lay them out on a parchment-lined tray in a single layer until frozen solid, then stack them with parchment paper between layers in an airtight container. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature and assemble with your jam filling.
What if my cookies turned out too dry or crumbly?
If your Sourdough Linzer Cookies are too dry, it could be due to overmixing or too much flour being incorporated. Always mix by hand when combining the dough and add a bit more moisture by gently incorporating a teaspoon of melted butter or a touch of milk if needed. The dough should be pliable but not sticky—finding the right balance is key!
Are these cookies suitable for people with nut allergies?
Yes, the Sourdough Linzer Cookies are nut-free, especially when made with the recommended gluten-free flour blend and without any nut-based fillings or toppings. Always check your specific ingredients to ensure they’re free from cross-contamination if you’re making these for someone with allergies.
How long should I let the cookies rest after assembly?
It’s essential to allow your assembled cookies to rest for about 12 hours before serving. This resting period helps to soften the cookies and meld the flavors, resulting in a much more enjoyable texture. After all, you want every bite to melt in your mouth!
