Biscoff Brownie Ingredients
For the Cookie Crust
• Crushed Biscoff Cookies – 1 ½ cups; forms the flavorful base crust. Substitute with any Biscoff-style cookies if needed.
• Salted Butter – ½ cup, melted; ensures a rich taste—cool before using to avoid cooking the eggs.
For the Brownie Batter
• Large Eggs – 2, room temperature; binds the ingredients for a perfect structure; use 2 flaxseed eggs for an eggless version.
• Granulated Sugar – ½ cup; sweetens the batter for that irresistible taste.
• Brown Sugar – ½ cup, packed; adds moistness and a hint of caramel flavor.
• Vanilla Extract – 2 tsp; elevates the overall flavor; vanilla bean paste is a lovely alternative.
• All-Purpose Flour – ½ cup; provides structure to these Biscoff brownies; gluten-free flour is a great substitution.
• Baking Cocoa – ⅓ cup unsweetened; delivers that deep chocolate richness; dark chocolate or Dutch-processed cocoa can work, too.
• Baking Powder – ¼ tsp; gives a slight lift for a balanced texture.
• Smooth Biscoff Spread – ⅓ cup; swirled in for added richness; warm it slightly if too firm to mix well.
Feel free to get creative with these ingredients, my fellow bakers!
Step‑by‑Step Instructions for Biscoff Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, grab an 8×8-inch baking pan and line it with parchment paper, leaving some overhang to easily lift out the brownies later. This little preparation makes for an effortless release from the pan and a perfect base for your delicious Biscoff brownies.
Step 2: Prepare the Crust
In a mixing bowl, combine 1 ½ cups of crushed Biscoff cookies with ½ cup of melted salted butter. Stir until the crumbs are fully coated and the mixture resembles wet sand. Press this mixture firmly into the bottom of the prepared baking pan to form an even crust. This buttery layer will be the perfect foundation for the fudgy brownie center.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, beat together 2 large room temperature eggs, ½ cup of granulated sugar, and ½ cup of packed brown sugar until the mixture is thick and creamy, which should take about 1 minute with an electric mixer. The blend should become pale and fluffy, creating a wonderful base for the luscious Biscoff brownies you’re about to create.
Step 4: Add Remaining Wet Ingredients
Carefully mix in the ½ cup of cooled melted butter and 2 teaspoons of vanilla extract to the egg-sugar mixture, stirring until everything is well combined. This adds a rich flavor dimension to your brownies that pairs perfectly with the Biscoff spread you’ll be using later. The consistency should feel smooth and silky as you incorporate these wet ingredients.
Step 5: Incorporate Dry Ingredients
Sift together ½ cup of all-purpose flour, ⅓ cup of unsweetened cocoa powder, and ¼ teaspoon of baking powder directly into the wet mixture. Gently fold the dry ingredients until just combined, being careful not to overmix. The batter should remain thick and glossy, providing the perfect fudgy texture for your Biscoff brownies.
Step 6: Pour and Swirl
Spread the brownie batter evenly over the prepared Biscoff cookie crust, using a spatula for an even layer. Then, spoon ⅓ cup of warm smooth Biscoff spread over the top in dollops. Take a knife and gently swirl the spread into the batter to create beautiful marbled patterns. This delightful step adds an irresistible, rich flavor burst to each bite of your brownies.
Step 7: Bake
Carefully place the baking pan in the preheated oven and bake for 22–25 minutes. Keep an eye on the brownies; they are done when the edges are set and a toothpick inserted into the center comes out mostly clean, with a few moist crumbs. Removing them at the right time ensures a rich, fudgy texture that will be a hit.
Step 8: Cool and Slice
Once baked, allow the Biscoff brownies to cool completely in the pan. This will take about an hour; patience is key! Once cool, grasp the parchment overhang and lift the brownies out of the pan. Cut them into squares using a sharp knife. For clean cuts, consider warming your knife in hot water before slicing. These decadent treats are then ready to be enjoyed!

Expert Tips for Biscoff Brownies
- Perfect Top: Whip the eggs and sugars until pale and fluffy to achieve that signature crackly top everyone loves.

Biscoff Brownies Recipe FAQs
What kind of Biscoff cookies should I use?
You can use any Biscoff-style cookies to create your crust. Crush them finely and try to avoid cookies with too many dark spots, which can indicate they are past their prime. If you can’t find Biscoff cookies, similar speculoos-style cookies will work wonderfully too!
How should I store leftover Biscoff brownies?
Store your Biscoff brownies in an airtight container at room temperature for up to 3 days. If you’d like them to last longer, you can also keep them in the fridge for about a week. Just make sure they are well-wrapped to prevent any drying out—nobody wants a dry brownie!
Can I freeze Biscoff brownies, and how?
Absolutely! To freeze your Biscoff brownies, first, ensure they’re completely cooled. Wrap them tightly in plastic wrap and then again in aluminum foil to avoid freezer burn. They can be frozen uncut for up to 2 months. When you’re ready to enjoy them, simply thaw in the fridge overnight, and they’ll be just as fudgy and delicious!
What if my brownies turned out too cakey?
If your brownies ended up cakey instead of fudgy, it could be due to overmixing after adding the dry ingredients or baking them for too long. Next time, mix just until combined and check for doneness a minute or two earlier. If you’d like extra fudginess, try adding a bit more chocolate or reducing the flour by a tablespoon.
Can I make these brownies gluten-free?
Yes, you can easily make these Biscoff brownies gluten-free by substituting the all-purpose flour with a gluten-free equivalent. Ensure all your ingredients, including the Biscoff cookies and Biscoff spread, are certified gluten-free. This way, everyone can enjoy a slice of this delightful treat!
Is there an eggless version of the Biscoff brownies?
Definitely! For an eggless version, replace the 2 large eggs with 2 flaxseed eggs. To make a flaxseed egg, mix 2 tablespoons of ground flaxseed with 6 tablespoons of water and let it sit for about 5 minutes until it becomes gel-like. This will help bind all the ingredients together beautifully, and you won’t miss the eggs at all!
