Substitutions & Variations
Note: This video is for demonstration purposes and may use a slightly different method.
I know how important it is to adapt recipes to suit your family’s specific dietary needs. You can easily modify these Sourdough Biscoff Cookies to be slightly healthier or to fit different dietary restrictions. If you want to lower the glycemic index, you can swap the brown sugar for coconut sugar, which adds a lovely toasted flavor.
For a dairy-free version, substitute the butter with a high-quality vegan butter stick or refined coconut oil. If you do not have Biscoff cookies on hand, you can use any ginger snap or graham cracker, though the flavor will change slightly.
You might even add dark chocolate chips to your Sourdough Biscoff Cookies if your children are chocolate lovers like mine. Always remember that the sourdough discard provides moisture, so if you use a gluten-free flour blend, ensure it contains xanthan gum to maintain the cookie’s structure.

Step-by-Step Instructions
Follow these simple steps to create the most delicious Sourdough Biscoff Cookies your family has ever tasted. The process is straightforward and quite relaxing once you get into the rhythm of mixing and scooping.
- Preheat your oven to 350 degrees Fahrenheit and line two large baking sheets with parchment paper or silicone mats.
- In a large mixing bowl, cream together the softened unsalted butter, Biscoff spread, brown sugar, and white sugar until the mixture is light and fluffy.
- Add the large egg and vanilla extract to the creamed mixture, beating well until fully combined.
- Gently stir in the sourdough discard. The Sourdough Biscoff Cookies benefit from this addition as it adds moisture and a slight lift.
- In a separate medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and sea salt.
- Gradually add the dry ingredients to the wet ingredients, mixing just until no flour streaks remain. Do not overmix the dough.
- Fold in the crushed Biscoff cookies by hand using a spatula to ensure they are evenly distributed throughout the Sourdough Biscoff Cookies dough.
- Using a cookie scoop, form balls of dough about two tablespoons in size and place them on the prepared baking sheets, leaving two inches of space between them.
- Bake for 10 to 12 minutes, or until the edges are golden brown but the centers still look slightly soft.
- Allow the cookies to cool on the baking sheet for five minutes before transferring them to a wire rack to cool completely.
Pro Tips for Success
To ensure your Sourdough Biscoff Cookies turn out perfectly every single time, I have gathered a few technical tips from my kitchen to yours. First, always measure your flour by weight or use the spoon-and-level method; too much flour will make the cookies cakey rather than chewy. Second, make sure your sourdough discard is not too old.
While a very sour discard is great for bread, a milder discard that is only a few days old works best for Sourdough Biscoff Cookies. If you prefer a thicker cookie, chill the dough in the refrigerator for at least thirty minutes before baking. Chilling the dough solidifies the fats, which prevents the cookies from spreading too much in the oven.
Finally, don’t be afraid to top each cookie with a tiny sprinkle of flaky sea salt right after they come out of the oven. This elevates the caramel notes in the Biscoff and makes the Sourdough Biscoff Cookies taste professional.
To perfect your Sourdough Biscoff Cookies, you can apply some of the technical insights from my experiences, which are also detailed in my guide on Sourdough Laminated Croissant Bread to ensure a delightful outcome every time.
Storage & Reheating Tips
Keeping your Sourdough Biscoff Cookies fresh is easy if you follow a few simple steps. You should store the completely cooled cookies in an airtight container at room temperature for up to five days. To maintain their soft texture, place a small piece of bread inside the container; the cookies will absorb the moisture from the bread.
If you want to keep them longer, these cookies freeze beautifully. Place the baked Sourdough Biscoff Cookies in a freezer-safe bag for up to three months. When you are ready for a treat, simply thaw them at room temperature or warm them in a 300-degree oven for three minutes.
You can also freeze the raw dough balls and bake them straight from the freezer—just add two extra minutes to the baking time. This is a lifesaver for busy moms who need a quick dessert!
What to Serve With This Recipe
While Sourdough Biscoff Cookies are spectacular on their own, I love serving them as part of a balanced snack or a light dessert. Since these cookies are rich and sweet, they pair wonderfully with a refreshing fruit salad featuring seasonal berries and melon. If you are serving these in the evening, a warm cup of herbal chamomile tea or a cold glass of almond milk complements the cinnamon spices beautifully.
For a more decadent treat, you can crumble the Sourdough Biscoff Cookies over a bowl of Greek yogurt or a scoop of vanilla bean ice cream. If you are hosting a brunch, these cookies look lovely on a platter next to roasted nuts and sliced apples. Providing a mix of sweet and naturally fresh options ensures there is something for everyone at the table.

FAQs
Can I use active sourdough starter instead of discard?
Yes, you can certainly use active starter for your Sourdough Biscoff Cookies. The only difference is that the cookies might rise a bit more and have a slightly lighter texture. The flavor will still be incredible, but since active starter is more bubbly, the dough may feel a bit stickier during the scooping process. If you use active starter, you might not need to chill the dough quite as long.
What if I don’t have Biscoff spread?
If you cannot find Biscoff spread, you can substitute it with any cookie butter or even a creamy natural peanut butter. However, if you use peanut butter, the flavor of your Sourdough Biscoff Cookies will shift toward a peanut-ginger profile. You could also try making a homemade cookie butter by blending spiced cookies with a bit of oil and sugar, although the texture may vary from the store-bought version.
Can I make the dough ahead of time and let it ferment?
Absolutely! In fact, letting your Sourdough Biscoff Cookies dough rest in the refrigerator for 24 hours allows the sourdough cultures to break down the gluten and phytic acid in the flour. This makes the cookies much easier to digest and deepens the overall flavor profile. Just make sure to cover the dough tightly with plastic wrap so it does not dry out or absorb any odors from the fridge.
Sourdough Biscoff Cookies blend the unique flavors of Belgian speculoos with the tang of sourdough, offering a creative way to utilize sourdough discard. These cookies not only provide a soft, chewy texture but also boast a delightful crunch from crushed Biscoff cookies, making them a beloved treat among cookie enthusiasts.
