Ingredients You’ll Need

1 cup creamy Biscoff cookie butter spread: This is the star of the show! Provides that delicious caramelized flavor. If you can’t find Biscoff, try another cookie butter or nut butter.
1 stick unsalted butter: Adds richness and helps achieve that fudgy texture. Use a higher-fat butter for best results.
1 cup light brown sugar: Lightly packed for moisture and sweetness. You can substitute with dark brown sugar for a more robust flavor.
1/4 cup granulated sugar: For added sweetness and balance.
2 large eggs plus 1 egg yolk: Using an extra yolk ensures a richer brownie. Make sure the eggs are cold for consistent mixing.
1 teaspoon vanilla extract: Enhances all the flavors. Go for pure vanilla for the best aroma.
1 tablespoon neutral oil: Such as vegetable or avocado oil to add moisture without overpowering the flavor.
3/4 cup cocoa powder: Unsweetened cocoa gives the brownies a rich chocolate flavor. Dutch-processed cocoa can be a good alternative for a softer flavor.
1/2 cup plus 2 tablespoons all-purpose flour: Measured correctly for structure. For gluten-free, substitute with a 1:1 blend.
1 tablespoon cornstarch: Contributes to the fudgy texture.
1/2 teaspoon fine sea salt: Balances sweetness and enhances flavor.
1/2 teaspoon instant espresso powder (optional): This enhances the chocolate and adds depth to the flavor without overt coffee notes.
1/4 teaspoon ground cinnamon: Adds a warm spice note that pairs beautifully with Biscoff.
4 biscoff cookies, coarsely chopped: For texture and an extra cookie crunch on top.

How to Make Biscoff Brownies

Prepare the Cookie Layer: Start by lining an 8 by 8-inch metal pan with foil or parchment paper, allowing some overhang for easy removal later. Place the creamy Biscoff cookie butter spread in a glass measuring cup and microwave it for about 20 to 30 seconds until it’s pourable but not hot. Pour this dreamy mixture into the prepared pan, spreading evenly. Freeze for 1 hour or until solidified.
Make the Brownie Batter: Preheat your oven to 325°F (163°C). Line the same pan with fresh foil or parchment paper and lightly spray it with nonstick cooking spray. In a large microwave-safe bowl, melt 1 stick of unsalted butter until completely melted. Whisk in 1 cup of light brown sugar and 1/4 cup of granulated sugar until combined, then let it cool until just warm. Add 2 large eggs and 1 egg yolk, whisking vigorously for about 1 minute.
Combine Ingredients: Whisk in 1 teaspoon of vanilla extract, 1 tablespoon of neutral oil, and 3/4 cup of cocoa powder. Using a rubber spatula, fold in 1/2 cup plus 2 tablespoons of all-purpose flour, 1 tablespoon of cornstarch, 1/2 teaspoon of fine sea salt, 1/2 teaspoon of optional instant espresso powder, and 1/4 teaspoon of ground cinnamon until there are no visible dry ingredients—this should all come together beautifully.
Layering the Brownies: Pour half of the brownie batter into the prepared pan and spread it evenly. Take the frozen sheet of Biscoff cookie butter and place it carefully over the batter. Pour the remaining brownie batter on top, making sure to cover the cookie layer completely. For the finishing touch, sprinkle the coarsely chopped Biscoff cookies over the top and gently press them in.
Bake to Perfection: Place in the preheated oven and bake for 32 to 35 minutes or until the brownies are set, with the edges slightly puffed. Avoid overcooking, as we want that fudgy texture! Allow the brownies to cool completely in the pan before lifting them out using the overhang for easy cutting.

Storing & Reheating

Store your Biscoff Brownies in an airtight container at room temperature for up to 3 days. They will remain delicious, though the texture will evolve—you can enjoy them warm for a gooey experience, at room temperature for a chewy bite, or chilled for a fudgy sensation. If you need longer storage, they can be frozen for up to 3 months. Just place them in a freezer-safe container, and when you want to indulge, let them thaw in the fridge before warming briefly in the microwave.

Chef’s Helpful Tips

When melting the butter, ensure it doesn’t become too hot, as this can alter the texture of the brownies.
For the best results, it’s essential to measure your flour correctly. Spoon it into your measuring cup and level it off, rather than scooping straight from the bag.
Avoid overmixing after adding the flour; this helps keep your brownies tender.
Feel free to experiment with the cookie topping—try different cookies or add chocolate chips for an extra layer of flavor.
For a deeper flavor, allow the brownies to rest overnight before indulging.

Biscoff Brownies are a rich, indulgent dessert that’s perfect for sharing…but honestly, you might want to keep them all to yourself! Their unique combination of flavors will have everyone asking for the recipe. As you bake, let your creativity shine—whether it’s an additional sprinkle of sea salt or a drizzle of chocolate, make these brownies your own. Enjoy every bite!

How do I know when the brownies are done?

A toothpick inserted into the center should come out with a few moist crumbs but not wet batter. Keep an eye on them as oven times can vary.
