An overhead shot of rectangular cocktail-inspired brownies arranged on a vintage marble bar surface, their dense fudgy texture visible from cross-sections that reveal subtle reddish-amber swirls. Soft backlighting highlights the glossy, crackly tops dusted with dehydrated orange zest and cocoa powder. Several squares feature decorative candied orange peels and crystallized cherries reminiscent of cocktail garnishes. A tumbler glass with bourbon sits alongside, while scattered Campari-infused chocolate pieces add vibrant color contrast against the dark, moist brownies. The natural window light catches the amber highlights, suggesting the complex bittersweet flavor of the classic Boulevardier cocktail transformed into decadent pastry form.

Directions

<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 180°C. Line a 20cm square baking tin with parchment paper, leaving some overhang to help with removal later. Lightly grease any exposed sides with butter. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> Create a double boiler by setting a heatproof bowl over a pan of gently simmering water (ensuring the bowl doesn't touch the water). Break the dark chocolate into pieces and add to the bowl along with the butter. Stir occasionally until completely melted and smooth. The gentle, indirect heat prevents the chocolate from seizing or burning. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Remove the chocolate mixture from heat and allow to cool slightly for about 5 minutes. This prevents the alcohol from evaporating and ensures the eggs won't scramble when added later. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> Stir in the bourbon, Campari, and sweet vermouth into the chocolate mixture. These three ingredients create the signature Boulevardier cocktail flavor profile - the bourbon provides warmth, the Campari adds bitterness, and the vermouth brings aromatic sweetness. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> In a large bowl, whisk together the sugar, eggs, and vanilla extract until the mixture becomes pale and slightly thickened (about 2 minutes). This incorporation of air helps create that perfect crackly brownie top. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> Fold the chocolate-alcohol mixture into the egg mixture using a spatula with a gentle hand. Mix just until combined - overworking the batter will develop gluten and result in cake-like rather than fudgy brownies. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Sift together the flour, cocoa powder, and salt, then gently fold into the batter until just incorporated. Some small streaks of flour are fine - they'll disappear during baking. Stir in the orange zest, which complements the Campari's bitter orange notes. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Pour the batter into the prepared tin, smoothing the top with a spatula. Tap the tin gently on the counter a few times to release any large air bubbles. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> Bake for 28-30 minutes until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The edges will appear set while the center remains slightly soft. Remember that brownies continue to cook slightly after removal from the oven, so it's better to slightly underbake than overbake for that perfect fudgy texture. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> While the brownies cool, prepare the glaze by whisking together the powdered sugar, bourbon, Campari, and sweet vermouth until smooth. The glaze should be thick but pourable - add a touch more powdered sugar if too thin or a few drops more liquid if too thick. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> Allow the brownies to cool in the tin for at least 30 minutes, then use the parchment overhang to lift them out and transfer to a wire rack. Let them cool completely before glazing - this prevents the glaze from being absorbed into the warm brownies. </li> <li class="MethodStepper"> <h4 class="step-title">Step 12</h4> Drizzle the glaze over the cooled brownies, then decorate with candied orange peel and crystallized cherries if desired. These garnishes echo the traditional Boulevardier cocktail garnishes and add a professional finishing touch. </li> <li class="MethodStepper"> <h4 class="step-title">Step 13</h4> Allow the glaze to set for about 20 minutes before cutting into squares. For the cleanest cuts, use a warm knife (run under hot water and wipe dry between slices). Store in an airtight container at room temperature for up to 5 days, with the flavor actually improving after the first day as the alcoholic notes mellow and integrate. </li> </ol>

Chef’s Notes

A few helpful details for making this recipe.

Can the alcohol be omitted from these boozy brownies for a non-alcoholic version?

Yes, you can create a non-alcoholic version by substituting the bourbon with vanilla extract, the Campari with orange juice and a few drops of bitters, and the vermouth with grape juice. This maintains similar flavour notes without the alcohol content, making them suitable for all ages.

What makes the texture of these brownies so fudgy rather than cakey?

The fudgy texture comes from the high ratio of fat to flour, minimal mixing once the flour is added, and slight underbaking. The melted chocolate and butter provide richness, while the small amount of flour prevents the development of a cakey structure. The alcohol also contributes to moisture retention.

How do I know when these brownies are perfectly baked?

The brownies are perfectly baked when a toothpick inserted in the centre comes out with a few moist crumbs attached, but not wet batter. The edges should be set while the middle remains slightly soft. Remember they continue cooking slightly after removal, so it's better to slightly underbake for optimal fudginess.
