It’s nostalgic and grown-up at the same time. When combined with sourdough, it creates a flavor that feels bakery-level without the bakery price tag.

Choosing the Right Sourdough Starter
Active vs Discard
Use discard. It doesn’t need to be bubbly or fed. Just make sure:
- It smells pleasantly tangy
- It’s not overly liquid
Hydration around 100% works perfectly.
Selecting the Best Biscoff Spread
Smooth works best for clean texture and stamping.
Crunchy? That’s fun too, it adds texture but may affect stamping detail slightly.

Step-by-Step Instructions
Let’s bake.
- Cream butter and Biscoff until smooth.
- Add sugars and beat until fluffy.
- Mix in sourdough discard, egg yolk, and vanilla.
- Whisk flour, baking soda, cinnamon, and salt separately.
- Gradually mix dry ingredients into wet mixture.
- Chill dough for at least 1 hour.
- Roll dough to ¼ inch thickness.
- Cut into circles.
- Stamp with cookie mold (press firmly).
- Chill stamped cookies 20 minutes.
- Bake at 350°F (175°C) for 10-12 minutes.

That’s it. Simple, right?

FAQs
Why are my sourdough biscoff cookies spreading too much?
Sourdough biscoff cookies usually spread if the dough is too warm or if the discard is too thin. Chill the dough for at least one hour before baking. Also, measure flour carefully and avoid over-creaming the butter.
Can I freeze sourdough biscoff cookie dough?
Absolutely. Roll the dough into balls and freeze on a baking sheet. Once solid, transfer to a freezer bag. Bake directly from frozen and add 1-2 extra minutes to baking time.
How long do sourdough biscoff cookies stay fresh?
Store sourdough biscoff cookies in an airtight container at room temperature for 4-5 days. They actually taste richer on day two because the spice and sourdough notes continue to develop.
There’s something incredibly satisfying about turning sourdough discard into something this beautiful. These cookies are crisp, warmly spiced, and layered with caramel flavor, just like the ones in the photos.
They’re simple enough for a weekday bake but impressive enough for gifting. Once you try them, they’ll become a regular in your kitchen rotation.
