Ingredients You’ll Need

This recipe uses a handful of simple but carefully chosen ingredients that each play a vital role in the texture, taste, and look of these brownies. From the bittersweet chocolate that brings richness to the flour and cocoa powder which make them perfectly fudgy, to the bourbon that infuses warmth and moisture, every item counts.

• All-purpose flour (1 cup / 120 grams): Provides structure for a perfectly fudgy but stable brownie.
• Dutch-processed cocoa powder (1/4 cup / 25 grams): Adds a deep, rich chocolate flavor and beautiful dark color.
• Baking powder (1/2 teaspoon): Gives just enough lift for a soft crumb without drying out the brownies.
• Kosher salt (1/4 teaspoon): Balances sweetness and enhances the chocolate’s complexity.
• Unsalted butter (6 tablespoons / 80 grams): Creates a tender texture and helps carry the flavor.
• Granulated sugar (3/4 cup / 150 grams): Sweetens while helping with that classic crackly top.
• Pure vanilla extract (1 teaspoon): Elevates flavor depth and complements the bourbon.
• Bourbon (1/2 cup, divided): The star ingredient that infuses warmth and moistness inside and out.
• Bittersweet chocolate, finely chopped (12 ounces / 340 grams, divided): Gives a rich, luxurious chocolate experience.
• Large eggs (2, room temperature): Bind the ingredients and provide moisture.
• Chopped pecans (1 cup / 80 grams, optional): Add a delightful crunch and nutty contrast.
• Buttercream butter, unsalted (1/2 cup / 110 grams, room temperature): The creamy base for the decadent buttercream.
• Confectioners’ sugar (1 cup / 120 grams): Sweetens and smooths the buttercream for perfect spreading.
• Biscoff cookie butter (1/4 cup / 65 grams): Brings a spiced, caramelized twist that makes the buttercream extra special.
• Bourbon for buttercream (1 tablespoon): Intensifies the boozy notes in the frosting.
• Chocolate chips, semisweet (3 ounces / 85 grams): For the shiny and smooth chocolate glaze.
• Unsalted butter for glaze (3 tablespoons): Adds richness and gives the glaze a glossy finish.

How to Make Bourbon-Brushed Biscoff Chocolate Brownies with Buttercream & Glaze Recipe

Step 1: Prepare Your Oven and Ingredients

Preheat your oven to 325°F (163°C) and line a brownie pan with parchment paper for easy removal. Having your eggs at room temperature and butter melted will make mixing smoother and assure the best texture in your brownies.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the all-purpose flour, Dutch-processed cocoa powder, baking powder, and kosher salt. This ensures even distribution of the leavening agent and salt, giving your brownies consistent flavor and rise.

Step 3: Melt the Butter and Chocolate

Gently melt 6 tablespoons of unsalted butter and half of the chopped bittersweet chocolate together until silky smooth. This mixture is the heart of your brownie batter, delivering intense chocolate richness that melts in your mouth.

Step 4: Combine Sugar, Vanilla, and Bourbon

Stir granulated sugar, vanilla, and half of the bourbon into the warm chocolate mixture. The sugar dissolves and the bourbon infuses the batter with its characteristic warmth and subtle complexity. This step is where the magic starts unfolding.

Step 5: Add Eggs and Dry Ingredients

Beat in the eggs one at a time until fully incorporated, then fold in the flour mixture carefully. The eggs give structure and moisture, while the flour blend holds everything together for that perfect fudgy texture.

Step 6: Stir in the Remaining Chocolate and Pecans

Fold in the remaining chopped bittersweet chocolate for bursts of melted chocolate in every bite and add chopped pecans if you dare—these nuts provide a satisfying crunch that adds a layer of texture to the luscious chewiness.

Step 7: Bake and Bourbon Brush

Pour the batter into your prepared pan and bake for about 25 to 30 minutes until set but still soft in the middle. As soon as they come out of the oven, brush the tops with the remaining bourbon. This final touch both moistens and flavors the brownies, creating a luscious surface with a boozy twang that’s absolutely unforgettable.

Step 8: Make the Bourbon Buttercream

In a mixing bowl, beat the room temperature butter until creamy. Gradually add confectioners’ sugar, Biscoff cookie butter, and bourbon, whipping until light and fluffy. This buttercream is dreamy—a perfect blend of buttery sweetness, that caramelized cookie flavor, and just the right kiss of bourbon intensity.

Step 9: Prepare the Chocolate Glaze

Gently melt the semisweet chocolate chips and unsalted butter together until smooth and glossy. This elegant glaze adds a beautiful, shiny finish that looks as good as it tastes on your brownies.

Step 10: Assemble the Brownies

Once the brownies have cooled to room temperature, spread the bourbon buttercream evenly on top. Then drizzle or pour the chocolate glaze over the buttercream layer, letting it set before cutting into perfect squares. This layering gives you a decadent combination of textures and flavors in every bite.

Garnishes

To elevate your presentation and flavor even more, consider sprinkling toasted pecan halves over the glaze or dusting a pinch of cocoa powder or cinnamon. A few crushed Biscoff cookies also add that signature caramel crunch and tie the whole theme together beautifully.

Side Dishes

Serve your bourbon-brushed brownies with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream to contrast the rich chocolate and bourbon flavors. A hot cup of coffee, espresso, or even a glass of bourbon on the rocks will complement these brownies wonderfully for an indulgent treat.

Creative Ways to Present

For a fun twist, try stacking the brownies into mini towers and drizzle extra glaze all around the plate for a decadent dessert display. You could also cut them into smaller bite-sized squares and serve on a platter for parties, making them irresistible finger treats. Personalize with edible gold leaf or fresh berries for a show-stopping presentation.

Make Ahead and Storage

Storing Leftovers

Keep leftover Bourbon-Brushed Biscoff Chocolate Brownies with Buttercream & Glaze Recipe well-covered in an airtight container at room temperature for up to three days to maintain freshness and moisture.

Freezing

These brownies freeze beautifully. Wrap individual pieces tightly in plastic wrap, then place them in a freezer-safe container or bag. They’ll stay delicious for up to two months. Thaw in the refrigerator overnight before enjoying.

Reheating

To enjoy warm brownies, simply microwave a piece for 10-15 seconds or heat gently in a low oven to revive that fresh-baked softness without melting the buttercream completely. This brings back that just-baked magic every time.

FAQs

Can I omit the bourbon?

Absolutely! While bourbon adds a wonderful depth and character to these brownies, you can leave it out for a non-alcoholic version. Consider using a teaspoon of vanilla extra or a splash of coffee for a complementary flavor boost instead.

Is Biscoff cookie butter necessary?

The cookie butter adds a unique caramelized, spiced flavor that truly elevates the buttercream, but if you don’t have it on hand, you can substitute with peanut butter or a simple vanilla buttercream. It won’t be quite the same, but still delicious!

Can I make these gluten-free?

Yes! Substitute all-purpose flour with a gluten-free all-purpose blend that includes xanthan gum. Just be sure the other ingredients you use are also gluten-free, and your brownies will retain that wonderful fudgy texture.

How long does the glaze take to set?

The chocolate glaze will usually firm up within 30 minutes at room temperature. To speed things up, you can pop the brownies in the fridge for 10-15 minutes, but don’t leave them too long or the buttercream might harden too much.

Can I use different nuts or skip nuts entirely?

Definitely! Feel free to swap pecans for walnuts, almonds, or hazelnuts, or leave them out if you prefer a nut-free treat. The brownies will still be fabulous with or without the added crunch.
