Gathering the right ingredients is the first joyful step toward creating your own batch of these Biscoff brownies. Each ingredient plays an important role — from adding moisture and sweetness to building that ideal fudgy texture and those deep flavors that set this treat apart.

Crushed Biscoff cookies (1 1/2 cups / 155g): Forms the crunchy, buttery crust that sets the stage for the brownies’ flavor.
Salted butter, melted and cooled (1/4 + 1/2 cup / 56g + 113g): Adds richness and helps bind the crust and batter while keeping the brownies moist.
Large eggs (2, room temperature): Bring structure and lift to the batter for the perfect fudgy crumb.
Granulated sugar (1/2 cup / 100g): Sweetens the batter and helps with that shiny brownie crust.
Light brown sugar, packed (1/2 cup / 100g): Adds subtle molasses notes that deepen the overall flavor and keep things chewy.
Vanilla extract or vanilla bean paste (2 tsp / 8g): Provides a warm, aromatic backdrop that enhances all the other flavors.
All-purpose flour (1/2 cup / 65g): Gives body to the batter, ensuring it holds together beautifully.
Unsweetened baking cocoa (1/3 cup / 33g): Delivers that classic, rich chocolate intensity we love in brownies.
Baking powder (1/4 tsp): A small lift agent to keep your brownies tender without being cakey.
Smooth Biscoff spread (1/3 cup / 80g): The crowning glory that you’ll swirl on top, creating those signature caramelized swirls bursting with flavor.

How to Make Biscoff Brownies Recipe

Step 1: Prepare Your Pan and Crust

Start by preheating your oven to 350°F (175°C) and lining an 8 x 8-inch baking pan with parchment paper. This ensures the brownies will lift out effortlessly once baked. Then, mix the crushed Biscoff cookies with 1/4 cup of the melted butter until you achieve a sandy, buttery crumb. Press this mixture firmly into the base of your pan using the back of a large spoon, forming a solid crust ready to hold the luscious brownie batter.

Step 2: Whip Up the Sugary Egg Mix

In a large bowl, crack in your two room temperature eggs, then add the granulated sugar and packed light brown sugar. Using either a hand or stand mixer on high speed, beat this blend for about a minute. The mixture will lighten in color and develop a creamy texture — this is the key to light, tender brownies that still have that dense fudginess.

Step 3: Combine Butter and Vanilla

Next, reduce the mixer speed to medium and pour in the remaining 1/2 cup of melted butter along with your vanilla extract or paste. Mix just until everything is smoothly combined. This step infuses the batter with that gorgeous buttery aroma that’s utterly comforting.

Step 4: Sift and Fold in Dry Ingredients

Sifting together the flour, cocoa powder, and baking powder ensures there are no lumps and that everything is evenly distributed. Sift these dry ingredients directly into your wet mixture, then carefully fold them in using a rubber spatula. Be gentle but thorough — you want a batter that’s perfectly combined, not overmixed, so the brownies stay tender with that moist crumb.

Step 5: Assemble Your Brownie Layers

Pour the chocolate batter on top of the Biscoff cookie crust and spread it out evenly with your spatula. Now for the magic touch: heat your Biscoff spread in the microwave for 5 to 10 seconds until soft and spreadable. Spoon dollops of this warm spread over the brownie batter, then take a butter knife and swirl it around creating pretty, marbled patterns. These swirls will bake into decadent pockets of caramelized spice.

Step 6: Bake to Perfection

Pop your pan into the oven and bake for 22 to 25 minutes. I’ve found that 23 minutes hits the sweet spot in most ovens — when a toothpick inserted into the center comes out mostly clean with a few moist crumbs. This balance gives you brownies that are perfectly moist on the inside and gently set on the edges.

Step 7: Cool and Cut

Once baked, remove the brownies from the oven and allow them to cool completely in the pan. Cooling is essential here because the brownies will firm up as they chill, making them easier to slice without crumbling. Once cool, lift them out using the parchment, cut into 16 squares, and get ready to indulge!

How to Serve Biscoff Brownies Recipe

A stack of eight square-shaped peanut butter swirl brownies is arranged on a white plate. Each brownie has two visible layers: the bottom layer is a rich, dark brown chocolate base with a fudgy texture, and the top layer is a lighter golden-brown peanut butter swirl with a smooth, slightly glossy finish creating swirling patterns on top. The brownies are thick, showing a dense and moist interior with a slightly crumbly edge. The plate sits on a white marbled surface with a blurred peanut butter jar in the background. photo taken with an iphone --ar 4:5 --v 7

Garnishes

To make these brownies even more special, try sprinkling a few crushed Biscoff cookies or a dusting of cocoa powder on top right before serving. For a touch of freshness, a tiny dollop of whipped cream or a drizzle of caramel sauce amplifies the cozy flavors, perfect for impressing friends or family.

Side Dishes

Pair your Biscoff Brownies with a scoop of vanilla ice cream or a glass of cold milk to balance the richness. A cup of strong black coffee or spiced chai tea also cuts through the sweetness beautifully, turning your dessert moment into a treasured ritual.

Make Ahead and Storage

Storing Leftovers

Whether you baked a whole batch or just want to keep some for later, store your brownies in an airtight container at room temperature for up to 3 days. If your kitchen is warm, it’s better to refrigerate them — they’ll stay fresh and moist there for about a week.

Freezing

If you want to keep these treats longer, freeze cut brownies in an airtight freezer bag or container. Layer them between sheets of parchment to prevent sticking. Frozen brownies will keep well for up to 3 months, making it easy to enjoy a sweet moment anytime you like.

Reheating

When you’re ready to enjoy frozen brownies, thaw them at room temperature for a couple of hours. For an extra tasty touch, pop them in a warm oven at 300°F (150°C) for about 5 minutes to bring back their gooey magic. Avoid microwaving too long to keep the texture just right.

FAQs

Can I use crunchy Biscoff spread instead of smooth?

Absolutely! Crunchy Biscoff spread will add an extra bit of texture to the brownie swirls. It might not swirl quite as smoothly but will pack even more delightful crunch and flavor.

Is it necessary to let the brownies cool completely before cutting?

Yes, cooling fully ensures the brownies set properly. Cutting warm brownies can lead to crumbling and messier squares, while cooled brownies cut cleanly and keep their shape beautifully.

Can I substitute the butter with an oil or dairy-free alternative?

While butter contributes to the flavor and texture of these brownies, you could substitute melted coconut oil in equal amounts for a dairy-free option. The texture might be slightly different but still delicious!

How do I know when the brownies are done baking?

Check by inserting a toothpick into the center: it should come out mostly clean with a few moist crumbs clinging to it. This means the brownies are fudgy inside but fully baked.

Can I double this recipe?

Yes! Just use a larger pan and adjust baking time accordingly. A 9 x 13-inch pan works well for doubled quantities, though you may need to bake a bit longer, checking doneness frequently.
