Biscoff Brownie Ingredients
For the Brownie Base
- Butter (250 g / 8.8 oz) – Adds richness and moisture; substitute with vegan butter for a dairy-free version.
- Chocolate (200 g / 1 cup) – Provides depth of flavor; use semi-sweet or dark chocolate for balanced sweetness.
- Sugar (115 g / ¾ cup) – Sweetens the brownies; coconut sugar can be a less refined alternative.
- Eggs (4) – Bind ingredients together and add structure; consider a flax egg for an egg-free alternative.
- Flour (90 g / ¾ cup) – Gives structure to the brownies; all-purpose flour is traditional, but almond flour significantly alters texture.
- Cocoa Powder (30 g / ¼ cup) – Intensifies chocolate flavor; be sure to use unsweetened cocoa for the best result.
- Salt (½ tsp) – Enhances flavors; adjust to taste to get that perfect balance.
For the Swirl and Crunch
- Crushed Biscoff Cookies (30 g / about 10 cookies) – Adds cookie crunch and flavor; more cookie butter can be swirled for extra richness.
- Cookie Butter (90 g / ¼ cup) – Swirled on top for additional indulgence; store-bought or homemade options work beautifully.
Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (180°C). To prepare for your Biscoff brownies, line an 8-inch square baking pan with parchment paper, leaving some overhang for easy removal later. This step ensures a perfect bake and hassle-free cleanup, so don’t skip it!
Step 2: Melt the Chocolate and Butter
In a heatproof bowl, melt the 250 g of butter and 200 g of chocolate together using a double boiler or microwave in short bursts. Stir the mixture until smooth and glossy, then set aside to cool slightly, allowing the rich chocolate aroma to fill your kitchen. The smoothness of the mixture is key to the fudgy texture you’ll achieve.
Step 3: Whisk the Eggs and Sugar
In a large mixing bowl, whisk together 4 eggs, 115 g of sugar, and a splash of vanilla extract until the mixture becomes pale and fluffy, about 2-3 minutes. This key step adds airiness to your batter, making those gooey brownies delightful. The whisked mixture should have a frothy appearance to indicate it’s ready for the next step.
Step 4: Combine the Mixtures
Carefully fold the cooled melted chocolate mixture into the whisked egg and sugar blend until combined. Use a spatula for gentle mixing, ensuring you don’t deflate the airiness from your previous step. The result should be a beautifully blended chocolate base that holds promise for your Biscoff brownies.
Step 5: Add Dry Ingredients
Sift in 90 g of flour, 30 g of cocoa powder, and ½ teaspoon of salt into the chocolate mixture. Gently fold with a spatula until just combined—be careful not to overmix! As you fold, you should see the rich, dark batter forming. The key is to maintain a gooey consistency that will result in fudgy brownies.
Step 6: Incorporate Biscoff Cookies
Next, stir in 30 g of crushed Biscoff cookies into the brownie batter, ensuring even distribution. The addition of these cookie bits will enhance the flavor and create delightful textures throughout your Biscoff brownies. Expect to see the delicious specks of cookie swirling through the chocolate mixture.
Step 7: Pour and Swirl
Pour the brownie batter into your prepared baking pan, smoothing the top with an offset spatula. Dot the surface with spoonfuls of 90 g of cookie butter, swirling it gently into the batter to create a beautiful marbled effect. This will add rich pockets of flavor that make every bite special.
Step 8: Add Extra Crunch
Before baking, sprinkle some more crushed Biscoff cookies on top of the batter for an extra crunch once baked. This not only adds visual appeal but enhances the flavor profile of your Biscoff brownies, creating a delightful contrast between the fudgy center and crunchy topping.
Step 9: Bake to Perfection
Transfer the pan to your preheated oven and bake for 30–35 minutes. The brownies should be set on top but still soft in the center—a toothpick inserted should come out with moist crumbs. Keep an eye on them to avoid overbaking; you want that perfect fudgy texture.
Step 10: Cool and Chill
Once baked, remove the brownies from the oven and allow them to cool completely in the pan on a wire rack. To achieve clean slices, refrigerate for at least 1 hour before cutting into squares. The chill will help firm up the gooey center, making it easier to enjoy every decadent bite.

Biscoff Brownies Recipe FAQs

How can I tell if my brownies are done baking?
To ensure perfectly gooey Biscoff brownies, you should check them with a toothpick. Insert it into the center—if it comes out with moist crumbs attached, your brownies are set! Remember, a little soft center is key to that fudgy texture we all love.
What’s the best way to store Biscoff brownies?
For optimal freshness, store your Biscoff brownies in an airtight container at room temperature for up to 3 days. If you want to keep them longer, they can be refrigerated for up to 5 days, which can actually enhance their flavor. Just allow them to come to room temperature before enjoying!
Can I freeze Biscoff brownies? How?
Absolutely! To freeze your Biscoff brownies, first cut them into squares and place them in a single layer in an airtight container—this helps to prevent sticking. They can be frozen for up to 3 months. When you’re ready to indulge, simply thaw them at room temperature or microwave for about 15-20 seconds for a quick warm-up.
Are there any dietary considerations I should be aware of?
If you’re making these brownies for a loved one with dietary restrictions, consider substituting eggs with a flax egg (1 tablespoon flaxseed meal mixed with 2.5 tablespoons water) for an egg-free option. Also, if you’re looking for a dairy-free treat, use vegan butter in place of regular butter, and select dairy-free chocolate. Always double-check labels to ensure all ingredients meet your dietary needs!
