Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare an 8×8-inch baking pan by lining it with parchment paper. This will ensure that your fudgy Biscoff brownies release easily after baking, showing off that beautiful golden crust.
Step 2: Make the Cookie Crust
In a medium bowl, combine crushed Biscoff cookies with melted salted butter, mixing until the mixture resembles wet sand. Press this crust firmly into the bottom of your prepared pan, ensuring an even layer that reaches all corners. It’s crucial for a solid foundation for your brownies, which will bake atop this delightful cookie base.
Step 3: Prepare the Brownie Batter
In a large mixing bowl, whip together large eggs and both granulated and light brown sugars until the mixture is light and creamy, about 2-3 minutes. Next, incorporate the melted butter and vanilla extract, stirring until fully combined. This step is essential for adding depth and moisture to your Biscoff brownies.
Step 4: Incorporate Dry Ingredients
Sift the all-purpose flour, unsweetened cocoa powder, and baking powder into the egg mixture. Carefully fold these ingredients into the batter using a spatula until just combined, being cautious not to overmix. The goal is a rich, fudgy batter that is slightly lumpy, ensuring your Biscoff brownies stay wonderfully gooey.
Step 5: Add to the Pan
Pour the brownie batter over the prepared cookie crust, using a spatula to spread it evenly across the surface. Make sure to reach the edges to create a uniform layer. This process layers the flavors beautifully, melding the richness of the brownies with the delightful crunch of the Biscoff crust.
Step 6: Swirl Biscoff Spread
Take the smooth Biscoff spread and heat it slightly in the microwave for about 10-15 seconds until it’s pourable. Dollop spoonfuls of the warmed Biscoff spread on top of the brownie batter, then use a knife to swirl it through the mixture gently. This creates beautiful marbled patterns and adds an indulgent taste to your brownies.
Step 7: Bake
Carefully place the pan in your preheated oven and bake the Biscoff brownies for 22-25 minutes. To check for doneness, insert a toothpick into the center; it should come out with a few moist crumbs. Keep a close eye on them to avoid overbaking, as these brownies shine when they remain fudgy!
Step 8: Cool and Serve
Once baked, remove your brownies from the oven and allow them to cool in the pan for at least 15 minutes. Afterward, transfer them to a wire rack to cool completely before cutting into squares. This step ensures your Biscoff brownies hold their shape and makes for cleaner slices.

Biscoff Brownies Recipe FAQs
How can I choose ripe and optimal Biscoff cookies for my brownies?
Absolutely! When selecting Biscoff cookies, look for packages with intact cookies without any dark or broken pieces. Check the expiration date to ensure maximum freshness; they should be crisp to enhance the texture of your brownies.
What’s the best way to store leftovers, and how long do they last?
You can store your Biscoff brownies in an airtight container at room temperature for up to 3 days. If you want them to last longer, place them in the refrigerator for about 1 week, though they may lose some of their fudginess.

Whenever you want to enjoy them, simply let them thaw in the refrigerator overnight, or reheat individual squares in the microwave for a quick treat.
What should I do if my brownies are too cakey instead of fudgy?
If your Biscoff brownies turned out too cakey, this usually happens due to overmixing or too much flour. To prevent this in future batches, make sure to mix the batter just until combined when adding the dry ingredients—don’t overdo it! Also, ensure you accurately measure your flour; using a kitchen scale can help achieve perfect proportions.
Are these brownies suitable for people with allergies?
While these Biscoff brownies are a divine treat, note that they contain gluten and dairy due to the all-purpose flour and butter.

Always read labels carefully to ensure safety for those with allergies!
Can I adapt this recipe for my pets?
It’s best to avoid giving these Biscoff brownies to your pets due to the ingredients like chocolate and sugar, which can be harmful to them. Instead, you can create a pet-friendly treat by substituting with safe ingredients such as mashed bananas or sweet potatoes mixed with oat flour.
