Ingredients You’ll Need

Gathering these simple yet essential ingredients is the first step to baking your dream Biscoff Brownies. Each one plays a key role in creating the perfect texture, rich flavor, and that beautiful balance of sweetness and spice you’ll notice from the very first bite.

3/4 cup Biscoff cookie butter: This star ingredient adds signature spiced caramel flavor and creamy texture.
1/2 cup light or dark brown sugar (packed): Adds moisture and depth of sweetness to complement the chocolate.
1/2 cup granulated sugar: Balances the sweetness and helps create a shiny crust on top.
2 large eggs: Bind everything together and provide structure to the brownies.
1 large egg yolk: Adds extra richness and helps keep brownies fudgy.
1 tablespoon vanilla extract: Enhances all the flavors and adds a warm, inviting aroma.
10 tablespoons unsalted butter: For creamy richness and to meld with the chocolate chips perfectly.
2/3 cup + 1/4 cup semi-sweet chocolate chips: Melts into the batter creating pockets of gooey chocolate bliss.
1/4 cup unsweetened Dutch cocoa powder: Gives the brownies that deep chocolate color and intense cocoa flavor.
2/3 cup + 1 tablespoon all-purpose flour: Provides the structure needed while keeping the brownies tender.
1 teaspoon espresso powder: Enhances the chocolate without tasting like coffee.
1/2 teaspoon fine sea salt: Balances the sweetness and intensifies the flavors.
4-5 Biscoff cookies (for the top): Adds crunch and an extra layer of that signature spiced flavor.
Extra cookie butter (for the top): To drizzle for an irresistible finishing touch.

How to Make Biscoff Brownies

Step 1: Prepare Your Pan and Cookie Butter Base

Start by pressing a large piece of parchment paper into an 8×8 inch metal baking pan and creasing the edges. Spread a generous layer of the Biscoff cookie butter evenly inside the creased edges, then pop it in the freezer until firm. This frozen cookie butter base is the delicious secret that makes these brownies stand out—it adds a creamy surprise in the middle that perfectly contrasts the fudgy batter.

Step 2: Line Your Pan and Preheat the Oven

Next, line your pan with parchment paper, making sure the paper hangs over all four sides to allow easy removal later. Preheat your oven to 350°F (180°C) so it’s ready to go once your batter is mixed.

Step 3: Whisk Together Your Sugars, Eggs, and Vanilla

In a large bowl, whisk the brown sugar, granulated sugar, eggs, egg yolk, and vanilla extract until fully combined and slightly thickened. This mixture provides the sweet, moist base that will carry all those luscious chocolate flavors.

Step 4: Melt Butter and Chocolate Chips

Melt the butter and 2/3 cup of semi-sweet chocolate chips together either in a microwave or over a double boiler, whisking until silky smooth. Add in the cocoa powder and whisk well before folding this rich chocolate mixture into the egg and sugar mixture. This step is what makes the Biscoff Brownies extra chocolatey and luscious.

Step 5: Add Dry Ingredients

Gently fold in the flour, espresso powder, and sea salt until just combined. Be careful not to overmix—this keeps your brownies tender rather than cakey.

Step 6: Layer the Batter and Cookie Butter

Pour half of the brownie batter into the prepared pan, spreading it evenly to the edges. Remove the cookie butter square from the freezer and peel off the parchment paper on top, then gently place it over the batter layer. Pour the remaining batter on top and spread it evenly again. This layered effect creates the signature texture and flavor contrast that makes these Biscoff Brownies so extraordinary.

Step 7: Add Toppings

Break the remaining Biscoff cookies into pieces and press them gently into the top of the batter. Warm a couple of tablespoons of cookie butter in the microwave until runny and drizzle it over the top, adding shine and extra spice-flavored sweetness.

Step 8: Bake to Perfection

Bake for 30–40 minutes at 350°F (180°C), or until a toothpick comes out with a few moist crumbs. Let the pan cool completely on a wire rack. For that final decadent touch, drizzle more cookie butter on top just before cutting into squares and serving.

How to Serve Biscoff Brownies

Garnishes

These brownies are incredible on their own, but a simple dusting of powdered sugar or a scoop of vanilla ice cream takes them up a notch. For an added pop, sprinkle chopped nuts or a few Biscoff cookie crumbs on top for a delightful crunch.

Side Dishes

Serve your Biscoff Brownies with fresh berries or a tangy yogurt parfait to balance the sweetness. A steaming cup of coffee or rich hot chocolate also pairs wonderfully, enhancing the espresso and chocolate notes baked inside the brownies.

Creative Ways to Present

Try serving Biscoff Brownies as part of a dessert platter with assorted chocolates and cookies for a special occasion. You can also cut them into miniature bites for parties or stack squares and drizzle caramel or chocolate sauce for an elegant dessert display.

Make Ahead and Storage

Storing Leftovers

Store your leftover Biscoff Brownies in an airtight container at room temperature for 2 to 3 days. This keeps them moist and fudgy without drying out, so each bite stays as delightful as the first.

Freezing

If you want to keep them longer, wrap the brownies tightly or place them in a freezer-safe container and freeze for up to one month. When wrapped well, the brownies keep their texture and flavor, ready whenever you get a craving.

Reheating

To enjoy your brownies warm, simply microwave a single piece for 15 to 20 seconds or reheat in a low oven for 5 to 10 minutes. The cookie butter will melt slightly, bringing back that just-baked magic.

FAQs

Can I use crunchy Biscoff cookie butter instead of smooth?

For this recipe, smooth Biscoff cookie butter works best to create that creamy middle layer and drizzle on top. Crunchy varieties might not spread or melt as evenly and could affect the texture of the brownies.

Can I substitute the espresso powder?

Yes! Espresso powder enhances the chocolate flavor without making the brownies taste like coffee. If you don’t have it, you can omit it, but the chocolate flavor will be a bit less intense.

What kind of pan is best for these brownies?

A metal 8×8 inch square pan is ideal because it conducts heat evenly, helping you get that perfect crust and fudgy center. Make sure to line it well with parchment paper for easy removal.

Can I make these brownies vegan?

This recipe relies heavily on eggs and butter for structure and richness, so vegan substitutions would require some experimentation. Using flax eggs and vegan butter might work, but expect some differences in texture and flavor.

How thick will the brownies be with the cookie butter layer?

The cookie butter layer adds a luscious middle layer without making the brownies overly thick. When baked in the 8×8 pan, expect a perfect balance of fudgy batter and creamy cookie butter in every bite.
