Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While it’s heating, take an 8×8-inch baking pan and line it with parchment paper, allowing a bit of overhang for easy removal later. This little preparation step ensures your fudgy Biscoff brownies cook evenly and don’t stick to the pan.
Step 2: Make the Cookie Crust
In a mixing bowl, combine 1 ½ cups of crushed Biscoff cookies with 1/4 cup melted butter. Use a fork or your fingers to mix until completely combined. Press this mixture firmly into the bottom of your prepared pan, creating a solid base. The crust should be compact and even, creating a delicious foundation for the brownies.
Step 3: Whip the Eggs and Sugars
In a large bowl, whip together 2 large room-temperature eggs, 1/2 cup granulated sugar, and 1/2 cup packed light brown sugar on high speed for about 1 minute, until the mixture turns creamy and smooth. This step is crucial for incorporating air, ensuring your Biscoff brownies develop that rich, fudgy texture.
Step 4: Incorporate Butter and Vanilla
Next, mix in 1/2 cup melted butter and 2 teaspoons of vanilla extract at medium speed until fully combined. The warm butter helps to create a silky texture. Keep an eye on the consistency; it should be glossy and homogeneous, layering in even more flavor to your brownie batter.
Step 5: Combine Dry Ingredients
In a separate bowl, sift together 1/2 cup of all-purpose flour, 1/3 cup of unsweetened cocoa powder, and 1/4 teaspoon of baking powder. Gradually fold this dry mix into your wet ingredients. Stir gently until just combined, making sure not to overmix – this helps maintain the rich fudgy texture of the Biscoff brownies.
Step 6: Pour and Smooth the Batter
Now, pour the brownie batter over the prepared cookie crust in your pan. Using a spatula, smooth the top into an even layer, ensuring every corner is filled. This step is crucial for achieving a beautifully baked brownie with a consistent texture and a perfect crust-to-brownie ratio.
Step 7: Add the Biscoff Swirl
Heat 1/3 cup of smooth Biscoff spread in the microwave for about 5-10 seconds to soften it. Drizzle the warmed cookie butter over the brownie batter, then use a butter knife to swirl it into the mixture. This creates delicious gooey pockets of flavor in your fudgy Biscoff brownies, enhancing each bite.
Step 8: Bake and Cool
Place the pan in your preheated oven and bake for 22-25 minutes. The brownies are done when a toothpick inserted into the center comes out mostly clean but with a few moist crumbs. Allow your brownies to cool completely in the pan on a wire rack, as this helps set their structure for clean slicing later.

Expert Tips for Biscoff Brownies
-
Room Temperature Eggs: Ensure your eggs are at room temperature for a fluffier and lighter brownie texture. Cold eggs can lead to a denser result.
-
Fine Crumbs: Use a food processor to crush Biscoff cookies into fine crumbs; larger pieces can disrupt the smooth texture of the cookie crust.
-
Metal Pans Preferred: Opt for metal baking pans rather than glass; metal conducts heat better, resulting in perfectly baked Biscoff brownies.
-
Chill for Neat Slices: Chill brownies in the pan before cutting. For even cleaner slices, use a warm, sharp knife to cut through the fudgy layers.
-
Mind the Baking Time: Avoid overbaking; your brownies should be taken out when a toothpick comes out mostly clean for optimal fudginess.

Reheating: For a warm delight, pop a brownie in the microwave for about 10-15 seconds. This will give you that gooey, fresh-out-of-the-oven experience!

Biscoff Brownies Recipe FAQs
How do I choose the right Biscoff cookies for the crust?
Absolutely! Look for Biscoff cookies that are fresh and free from any dark spots or signs of staleness. The crunchier, the better! If you can’t find Biscoff cookies, graham cracker crumbs make a great alternative for the base of your cookie crust.
What is the best way to store leftover brownies?
You can store your Biscoff brownies in an airtight container at room temperature for up to 3 days. This helps them maintain their delightful fudgy texture. If they last longer than that (which is rare!), you can also refrigerate them for up to a week for a cooler treat—just give them time to return to room temperature before serving.
Can I freeze Biscoff brownies, and how?
Definitely! To freeze your Biscoff brownies for future indulgence, wrap them tightly in plastic wrap, then cover with aluminum foil. This prevents freezer burn and keeps them fresh. They can be frozen for up to 2 months. When you’re ready to enjoy, simply thaw them overnight in the refrigerator. If you prefer a warm brownie, microwave for 10-15 seconds after thawing for that fresh-out-of-the-oven experience!
Why are my brownies not as fudgy as I expected?
Very often, overbaking is the culprit when brownies turn out less fudgy. Keep an eye on them while baking; they should come out with a toothpick that has a few moist crumbs, not completely clean. Additionally, make sure you’ve measured your flour accurately, as too much can lead to drier brownies. If you want to experiment, use a dark baking pan and reduce the baking time by a couple of minutes.
Are Biscoff brownies safe for people with nut allergies?
While Biscoff cookies and spread are typically nut-free, always check the packaging for allergen statements. If you’re serving guests with allergies, it’s wise to use a certified nut-free cookie butter or make your own from scratch to ensure safety. It’s always better to be safe and let everyone enjoy this decadent treat worry-free!
Can I make the recipe gluten-free?
Absolutely! To create gluten-free Biscoff brownies, simply substitute regular all-purpose flour with a gluten-free blend. Make sure the cookie crumbs you use for the crust are also gluten-free. Most brands of Biscoff cookies are naturally gluten-free, but always double-check labels to be safe. Enjoy your baking adventure!
