Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and prepare an 8 x 8-inch baking pan by lining it with parchment paper. This will ensure the brownies easily lift out without sticking, making your cleanup a breeze. Once preheated, it’s time to create the crust for your delicious Biscoff brownies.
Step 2: Make the Crust
In a mixing bowl, combine 1 1/2 cups of crushed Biscoff cookies with 1/4 cup of melted butter. Stir well until the mixture resembles wet sand. Next, press this crumbly mixture firmly into the bottom of the lined baking pan to form an even crust. This step adds a delightful base that perfectly complements the fudgy brownies that are about to follow.
Step 3: Cream Together the Sugars and Eggs
In a medium bowl, beat together 2 large eggs, 1/2 cup granulated sugar, and 1/2 cup packed light brown sugar for about 1 minute, or until the mixture appears light and creamy. This is essential for creating a fluffy texture in your brownies. The combination of sugars will enhance the sweetness and aid in achieving that rich, indulgent flavor found in your Biscoff brownies.
Step 4: Incorporate Wet Ingredients
Add 1/4 cup of melted butter and 2 teaspoons of vanilla extract to the egg and sugar mixture. Blend together until fully incorporated. The melted butter brings additional moisture and richness, while the vanilla enhances the overall aroma and flavor of your brownies. Make sure everything is well mixed before proceeding to the dry ingredients.
Step 5: Add Dry Ingredients
Sift in 1/2 cup all-purpose flour, 1/3 cup unsweetened cocoa powder, and 1/4 teaspoon baking powder into the batter. Gently fold these dry ingredients into the wet mixture until just combined; be careful not to overmix. You want to maintain that fudgy texture that makes these Biscoff brownies so irresistible.
Step 6: Pour the Batter
Carefully pour the brownie batter over the prepared crust in the baking pan. Use a spatula to spread it evenly, ensuring every corner is filled. This creates a delicious layer of rich chocolate flavor atop the crunchy Biscoff cookie crust, setting the stage for the final, creamy swirl of cookie butter.
Step 7: Swirl in the Biscoff Spread
Warm 1/3 cup of smooth Biscoff spread in the microwave for about 5-10 seconds until it’s slightly melted, making it easier to swirl. Spoon dollops of the melted Biscoff spread onto the brownie batter, then use a butter knife to gently swirl it through the batter. This step adds a luxurious creamy texture and amplifies that heavenly Biscoff flavor.
Step 8: Bake the Brownies
Place the pan in the preheated oven and bake for 22-25 minutes. Check for doneness by inserting a toothpick into the center— it should come out mostly clean with a few moist crumbs. This ensures your Biscoff brownies will be fudgy and not overcooked. Once done, remove from the oven and let cool completely in the pan.
Step 9: Slice and Serve
Once the brownies have cooled completely in the pan, carefully lift them out using the parchment paper. Use a sharp knife, preferably warmed, to slice them into squares. This step creates clean edges that beautifully showcase the swirls of cookie butter. Now, you’re ready to enjoy these decadent Biscoff brownies!

Biscoff Brownies Recipe FAQs
How do I choose the right Biscoff cookies for the crust?
Absolutely! When selecting Biscoff cookies, look for those that are not broken or overly crumbly. Fresh cookies will yield a better crumb for your crust, ensuring it holds together well. You want that crunchy base to contrast beautifully with the fudgy texture of the brownies.
What’s the best way to store Biscoff brownies?
Very good question! To keep those delicious Biscoff brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, place them in the fridge, wrapped tightly, for up to a week, or freeze them for up to 2 months. Be sure to let them cool completely before storage to maintain their texture and flavor.
Can I freeze Biscoff brownies? If so, how?
Certainly! To freeze your Biscoff brownies, let them cool completely, then cut them into squares. Wrap each square tightly in plastic wrap and place in an airtight container or freezer-safe bag. They can be frozen for up to 2 months. When you’re ready to indulge, simply thaw them in the fridge overnight, or warm them briefly in the microwave.
What if my brownies come out too dry?
Oh no! If your brownies seem dry, it could be due to overbaking or not enough moisture. Check the baking time; the toothpick should come out with moist crumbs, not clean. If they turned out too dry, consider adding a scoop of vanilla ice cream or serving with whipped cream to enhance that fudgy experience!
Are these Biscoff brownies safe for allergies?
When it comes to dietary considerations, these Biscoff brownies contain eggs and gluten from flour, which could be problematic for some. For egg allergies, you can substitute with flaxseed eggs, and for a gluten-free option, use a 1:1 gluten-free flour blend. Always check the labels on the Biscoff products for potential allergens!
How can I make these Biscoff brownies eggless?
Of course! To create an eggless version of these yummy Biscoff brownies, simply replace each egg with 1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water.
