• 2 teaspoons vanilla extract

Ingredient Notes

Cookie Butter

Use smooth cookie butter for the easiest swirling. Warm it in the microwave for 10–15 seconds if it’s too thick.

Cocoa Powder

Unsweetened natural cocoa creates a rich chocolate flavor. Dutch-process cocoa also works and produces an even darker brownie.

Chocolate Chips

Semi-sweet chocolate balances the sweetness of the cookie butter, but dark chocolate chips are an excellent alternative for a deeper flavor.

Brown Sugar

A combination of granulated and brown sugar creates moist, chewy brownies with a slightly caramel-like finish.

Biscoff Cookies

Roughly crushing the cookies instead of finely crushing them gives the brownies more texture and visual appeal.

Step-by-Step Instructions

1. Prepare the Baking Pan

Preheat your oven to 350°F (175°C).

Line an 8×8-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.

Lightly grease the paper.

2. Mix the Wet Ingredients

In a large mixing bowl, whisk together:

• Melted butter
• Granulated sugar
• Brown sugar

Whisk until smooth and glossy.

Add the eggs one at a time, mixing well after each addition.

Stir in the vanilla extract.

3. Add the Dry Ingredients

Sift together:

• Cocoa powder
• Flour
• Baking powder
• Salt

Fold the dry ingredients into the wet mixture using a rubber spatula.

Mix only until combined.

4. Fold in the Chocolate Chips

Add the chocolate chips and gently fold them throughout the batter.

The batter should be thick and glossy.

5. Assemble the Brownies

Spread about two-thirds of the brownie batter into the prepared pan.

Warm the cookie butter slightly until pourable.

Drop spoonfuls of cookie butter over the batter.

Add the remaining brownie batter on top.

Use a butter knife or skewer to gently swirl the cookie butter throughout the brownie batter.

Sprinkle the crushed Biscoff cookies evenly over the surface.

6. Bake

Bake for 32–36 minutes.

The edges should be set while the center remains slightly soft.

A toothpick inserted near the center should come out with moist crumbs rather than wet batter.

7. Cool Completely

Allow the brownies to cool in the pan for at least one hour.

For cleaner slices, refrigerate them for 30 minutes before cutting.

8. Decorate

Drizzle melted cookie butter over the brownies.

Top with extra crushed Biscoff cookies and a pinch of flaky sea salt if desired.

Slice into 16 squares and serve.

Expert Tips

Use Room Temperature Eggs

Room-temperature eggs blend more smoothly into the batter, creating a better texture.

Don’t Overbake

Brownies continue cooking slightly as they cool. Removing them while the center is still a bit soft ensures a fudgy result.

Warm the Cookie Butter

Slightly warming the cookie butter makes it easier to create beautiful swirls.

Let the Brownies Cool

Patience pays off. Fully cooled brownies slice more cleanly and develop an even fudgier texture.

Use Quality Chocolate

The better the chocolate, the richer the finished brownies will taste.

Variations

Triple Chocolate Biscoff Brownies

Add white chocolate and dark chocolate chunks along with the semi-sweet chips.

Espresso Brownies

Mix one teaspoon of espresso powder into the cocoa for a deeper chocolate flavor.

Nutty Cookie Butter Brownies

Fold chopped pecans or walnuts into the batter.

Salted Caramel Version

Drizzle salted caramel over the brownies before serving.

Cheesecake Swirl Brownies

Add dollops of sweetened cream cheese alongside the cookie butter before swirling.

Storage Instructions

Store brownies in an airtight container.

• Room temperature: Up to 4 days
• Refrigerator: Up to 1 week

Place parchment paper between layers to prevent sticking.

Reheating Tips

These brownies are delicious at room temperature, but for an extra indulgent dessert:

• Microwave one brownie for 10–15 seconds.
• Serve warm with vanilla ice cream.

Avoid overheating, which can dry out the texture.

Common Mistakes to Avoid

• Overmixing the batter after adding flour.
• Baking until completely dry.

• Skipping the parchment paper.
