How to Make Biscoff Brownies Recipe

Step 1: Prepare the Cookie Butter Base

Start by pressing a large piece of parchment paper into an 8×8-inch square metal baking pan and creasing the edges for easy removal later. Then evenly spread the Biscoff cookie butter inside the creased square and pop it in the freezer until it’s firm. This chilled cookie butter base creates a luscious layer that melts into the brownies for incredible flavor contrasts.

Step 2: Line the Pan and Preheat Oven

Once the cookie butter is firm, line the baking pan with parchment paper, letting it hang over all four sides for simple lifting after baking. Preheat the oven to 350°F (180°C) so it’s ready to give the brownies their perfect finish.

Step 3: Mix the Sugars and Eggs

Whisk together the brown sugar, granulated sugar, eggs, and vanilla extract until everything is well combined and slightly thickened. This mixture is where the sweet, velvety sweetness begins to build.

Step 4: Melt Butter and Chocolate

Gently melt the butter and semi-sweet chocolate chips together until silky smooth. Then whisk in the cocoa powder, combining everything to create that deep, rich chocolate base that will make these brownies unforgettable.

Step 5: Combine Chocolate Mixture with Egg Mixture

Slowly whisk the melted chocolate mixture into the sugar and egg mixture until just combined, ensuring the batter stays light and airy enough for fudgy perfection.

Step 6: Fold in Dry Ingredients

Fold in the flour, espresso powder, and sea salt carefully until just incorporated. Avoid overmixing to keep the brownies tender and soft rather than tough.

Step 7: Layer the Batter and Cookie Butter

Pour half of the brownie batter into the prepared pan and spread it out evenly. Then carefully place the chilled Biscoff cookie butter square on top, peeling off any parchment from the top of the butter. Pour the remaining batter over the cookie butter and smooth it out thoughtfully, creating a luscious sandwich of flavors.

Step 8: Add Cookie Topping and Drizzle

Break the Biscoff cookies into pieces and press them gently onto the top layer of brownie batter. Warm a couple of tablespoons of extra cookie butter in the microwave for about 15-20 seconds until runny, and drizzle it generously over the top for a glossy, irresistible finish.

Step 9: Bake to Fudgy Perfection

Bake the brownies in your preheated oven for 30 to 40 minutes. The brownies are ready when a toothpick inserted into the center comes out with just a few moist crumbs clinging to it. Let the brownies cool completely on a wire rack, then if you like, add a little extra cookie butter drizzle before slicing and serving.

Garnishes

These brownies are already bursting with flavor, but topping them with a light dusting of powdered sugar, a small dollop of whipped cream, or a scoop of vanilla ice cream adds an elegant touch. Even a few extra crushed Biscoff cookies make the top irresistible with extra crunch.

Side Dishes

Pair your Biscoff brownies with a cup of rich coffee or a glass of cold milk for a simple yet satisfying treat. If you want something a little fancier, serve with a berry compote or a drizzle of salted caramel sauce for an indulgent dessert experience.

Creative Ways to Present

For parties or gift-giving, cut these brownies into small, bite-sized squares and arrange them in a pretty box lined with parchment paper. You can also plate with a swipe of cookie butter on the side or stick toothpicks in each piece for easy grabbing at gatherings.

Make Ahead and Storage

Storing Leftovers

Keep any leftover Biscoff brownies in an airtight container at room temperature for 2 to 3 days. This helps preserve the chewy fudgy texture while keeping the flavors bright and fresh.

Freezing

If you want to save these for later, freeze the baked brownies in an airtight container or freezer bag for up to one month. Just thaw completely at room temperature before serving for the best taste and texture.

Reheating

To bring back that freshly baked warmth, gently warm individual brownies in the microwave for 15 to 20 seconds. This will soften the cookie butter and chocolate to melt perfectly on your tongue.

FAQs

Can I use crunchy Biscoff cookie butter instead of smooth?

While you can experiment with crunchy Biscoff cookie butter, the smooth version is preferred for the base layer and batter to achieve that silky texture in your brownies.

Is there a substitution for espresso powder?

You can leave out espresso powder if needed, but it really enhances the chocolate flavor without adding any coffee taste, so it’s worth including if you have it.

Do I really need to chill the cookie butter layer before adding the batter?

Yes! Chilling the cookie butter layer ensures it stays nicely set and doesn’t mix into the brownie batter, creating a beautiful distinct layer for texture and flavor.

Can I use a glass baking dish instead of metal?

Metal pans are recommended for even heat distribution when baking brownies, but glass dishes can work if you adjust baking time slightly and watch carefully.

How do I measure flour correctly for this recipe?

Spoon the flour lightly into your measuring cup and level it off with a knife rather than scooping directly from the bag to avoid packing too much flour and making dense brownies.
