Ingredients You’ll Need
Gathering the right ingredients is key to nailing these brownies.

Plus, the espresso powder subtly enhances the chocolate intensity without overpowering the Biscoff magic.
- 3/4 cup Biscoff cookie butter: This star ingredient adds that signature spiced caramel flavor and creamy texture that sets these brownies apart.
- 1/2 cup light or dark brown sugar, packed: Adds moisture and a subtle hint of molasses for depth.

- 2 large eggs: Provide structure and richness to the batter.
- 1 large egg yolk: Extra fat for fudginess and smoothness.
- 1 tablespoon vanilla extract: Enhances all the flavors with a warm, aromatic touch.
- 10 tablespoons unsalted butter: Melts into the chocolate creating a silky base.

- 1/4 cup unsweetened Dutch cocoa powder: Intensifies chocolate flavor and adds depth.
- 2/3 cup + 1 tablespoon all-purpose flour: Provides the perfect structure without weighing down the brownies.

How to Make Biscoff Brownies
Step 1: Prepare the Cookie Butter Base
Start by pressing a piece of parchment paper into your 8×8 baking pan, creasing it along the edges so you can see the pan shape once removed. Spread the Biscoff cookie butter evenly inside the creased lines and pop it into the freezer until it’s completely firm. This frozen layer will provide a luscious surprise in the middle of your brownies, so don’t rush this step!
Step 2: Mix the Sugars and Eggs
In a bowl, whisk together the brown sugar, granulated sugar, eggs, egg yolk, and vanilla extract until everything is thoroughly combined and slightly frothy. This ensures those brownies will be tender and full of flavor.
Step 3: Melt the Butter and Chocolate
Gently melt the butter with the chocolate chips until smooth and glossy, either in a microwave in short bursts or over a double boiler. Once melted, whisk in the Dutch cocoa powder until evenly mixed. This rich mix will be the heart of your brownies’ intense chocolate flavor.
Step 4: Combine the Wet and Dry
Pour the chocolate mixture into the egg-sugar mixture and whisk until just combined. Then fold in the flour, espresso powder, and sea salt gently. Be careful not to overmix here—you want to keep the brownies dense and fudgy.
Step 5: Layer the Batter and Cookie Butter
Pour half the brownie batter into your prepared pan, spreading it evenly to the edges. Carefully remove the parchment from the frozen cookie butter square and place it on top of the batter. Then pour the remaining batter on top, spreading it gently to cover the cookie butter completely.
Step 6: Garnish and Bake
Break up the Biscoff cookies into bite-sized pieces and press them gently onto the surface of the batter. Warm a couple of tablespoons of cookie butter until runny and drizzle this over the top for that irresistible glossy finish. Bake at 350 F (180 C) for 30 to 40 minutes until a toothpick comes out with a few moist crumbs. Let cool completely before removing from the pan.
How to Serve Biscoff Brownies

Garnishes
The best way to enhance the already wonderful texture and flavor is with a little extra drizzle of warmed cookie butter or a dusting of powdered sugar. For some added fun, sprinkle chopped nuts or mini chocolate chips for crunch and extra chocolate bursts.
Side Dishes
Serve these Biscoff Brownies alongside a scoop of vanilla ice cream or a dollop of whipped cream to contrast the dense fudgy texture with creamy coldness. A cup of rich coffee or chai tea complements the caramel and spices beautifully, creating a full dessert experience.
Creative Ways to Present
Consider cutting the brownies into small squares and threading them onto skewers with fresh berries for a fun party treat. Alternatively, layer chunks of these brownies in parfait glasses alternating with layers of whipped cream and crushed Biscoff cookies for a decadent layered dessert.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover Biscoff Brownies tightly and store them in an airtight container at room temperature for 2 to 3 days. Keeping them covered well ensures they stay soft and fresh without drying out.
Freezing
If you want to keep these brownies longer, they freeze beautifully. After baking and cooling, slice them and place in an airtight container or freezer bag with parchment paper layers between brownies. They keep well for up to one month in the freezer.
Reheating
To bring frozen or stored brownies back to that freshly-baked taste, warm individual pieces in the microwave for about 15 seconds or pop them briefly in a preheated oven. A light warming will melt the internal cookie butter, making each bite gooey and irresistible again.
FAQs
Can I use crunchy Biscoff cookie butter instead of smooth?
While smooth cookie butter gives the best texture in the batter, crunchy Biscoff can add a fun twist, especially if you enjoy little bits of cookie throughout. Just be mindful it might change the consistency slightly.
What if I can’t find espresso powder?
If espresso powder isn’t handy, you can leave it out or substitute it with instant coffee granules. Remember, a little goes a long way in enhancing the chocolate without adding bitterness.
Do I have to use Dutch cocoa powder?
Dutch-processed cocoa has a milder and smoother flavor than natural cocoa, which works well here. But you can use natural cocoa powder; just expect a more robust, slightly acidic chocolate flavor.
How thick should the cookie butter layer be?
A thin, even layer about 1/4 inch thick works perfectly. Too thick, and it might overwhelm the brownies; too thin, and you miss out on that luscious center surprise.
Can I make these gluten-free?
Absolutely! Just swap the all-purpose flour for your favorite gluten-free blend, making sure it contains xanthan gum or similar for structure. The brownies should turn out just as fudgy and flavorful.
Final Thoughts

- 10 tablespoons (140 g) unsalted butter
- 2/3 cup + 1/4 cup (156 g) semi-sweet chocolate chips
- 1/4 cup (25 g) unsweetened Dutch cocoa powder
- 2/3 cup + 1 tablespoon (90 g) all-purpose flour
- 1 teaspoon espresso powder
- 1/2 teaspoon fine sea salt
Topping
- 4–5 Biscoff cookies
- Extra cookie butter, for drizzling (about 2 tablespoons)
Instructions
- Prepare Cookie Butter Layer: Press a large piece of parchment paper into an 8×8 inch square metal baking pan, creasing the bottom edges to outline the pan size. Evenly spread 3/4 cup of Biscoff cookie butter inside the creased edges. Place the pan in the freezer and chill until the cookie butter layer is firm, checking carefully before proceeding.
- Line and Preheat: Line the baking pan with parchment paper, allowing it to hang over all four sides for easy brownie removal later. Preheat your oven to 350°F (180°C).
- Mix Sugar and Eggs: In a large bowl, whisk together 1/2 cup brown sugar, 1/2 cup granulated sugar, 2 large eggs, 1 egg yolk, and 1 tablespoon vanilla extract until the mixture is well combined and slightly thickened.
- Melt Butter and Chocolate: Gently melt 10 tablespoons unsalted butter and 2/3 cup plus 1/4 cup semi-sweet chocolate chips together until smooth. Whisk in 1/4 cup unsweetened Dutch cocoa powder until fully incorporated.
- Combine Chocolate with Eggs: Slowly whisk the melted chocolate mixture into the egg and sugar mixture until just combined, taking care not to overmix.
- Add Dry Ingredients: Fold in 2/3 cup plus 1 tablespoon all-purpose flour, 1 teaspoon espresso powder, and 1/2 teaspoon fine sea salt until just combined, maintaining a fudgy texture.
- Layer the Brownies: Pour half of the brownie batter (approximately 340 grams) into the prepared pan, spreading it evenly to the edges. Remove the frozen cookie butter layer from the freezer and peel off the top parchment paper. Place the cookie butter square carefully on top of the batter. Pour the remaining batter over the cookie butter and smooth evenly.
- Add Toppings: Break 4-5 Biscoff cookies into pieces and press them gently over the top of the brownie batter. Warm about 2 tablespoons of extra cookie butter in the microwave for 15-20 seconds until runny, then drizzle it over the cookie pieces for added flavor and shine.
- Bake: Bake the brownies in the preheated oven for 30-40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs clinging to it—avoid baking until fully dry.
- Cool and Serve: Remove the brownies from the oven and cool completely on a wire rack. For extra indulgence, drizzle more cookie butter on top before cutting. Slice into squares and enjoy!
- Storage: Store leftover brownies in an airtight container at room temperature for 2-3 days. For longer storage, freeze baked brownies in an airtight container or freezer bag for up to 1 month.
Notes
- Measure your flour properly using the spoon-level method: fluff the flour, spoon it into a measuring cup, then level it off with a knife to avoid using too much flour and ensure fudgy brownies.
- Use parchment paper to line the pan with an overhang for easy removal of the entire brownie slab once baked and cooled.
- Chilling the cookie butter layer until firm is crucial to prevent it from melting into the brownie batter.
- Espresso powder enhances the chocolate flavor without adding a coffee taste; omit if desired but it’s highly recommended.
- For best results, use high-quality semi-sweet chocolate chips and Dutch-processed cocoa powder for a rich chocolate taste.
- Allow brownies to cool completely before slicing to maintain clean edges and prevent crumbling.
