Ingredients
Scale
Batter
- 1 cup (120 grams) all-purpose flour
- 1/4 cup (25 grams) Dutch-processed cocoa powder
- 1/2 teaspoon baking powder
- 1/4 teaspoon kosher salt
- 6 tablespoons (80 grams) unsalted butter
- 3/4 cup (150 grams) granulated sugar
- 1 teaspoon pure vanilla extract
- 1/2 cup bourbon, divided
- 12 ounce (340 grams) bittersweet chocolate, finely chopped, divided
- 2 large eggs, at room temperature
- 1 cup (80 grams) chopped pecans (optional)
Bourbon Buttercream
- 1/2 cup (110 grams) unsalted butter, at room temperature
- 1 cup (120 grams) confectioners’ sugar
- 1/4 cup (65 grams) Biscoff cookie butter
- 1 tablespoon bourbon
Chocolate Glaze
- 3 ounce (85 grams) semisweet chocolate chips
- 3 tablespoons unsalted butter
Instructions
- Preheat and prepare pan: Preheat your oven to 325°F (163°C). Line an 8×8 inch baking pan with parchment paper, allowing some overhang on the sides for easy removal.
- Sift dry ingredients: In a mixing bowl, sift together the all-purpose flour, Dutch-processed cocoa powder, baking powder, and kosher salt. Set aside.
- Melt butter and chocolate: In a heatproof bowl set over simmering water, melt 6 tablespoons of unsalted butter with half (6 ounces) of the finely chopped bittersweet chocolate, stirring until smooth and combined. Remove from heat and allow to cool slightly.
- Mix wet ingredients: Stir the granulated sugar and vanilla extract into the melted butter and chocolate mixture until well combined. Add 1/4 cup of the bourbon and mix well.
- Add eggs: Beat in the eggs one at a time, mixing thoroughly after each addition to incorporate them fully into the batter.
- Combine dry and wet ingredients: Gradually fold the sifted dry ingredients into the wet mixture using a spatula until just combined, being careful not to overmix.
- Add nuts and remaining chocolate: Fold in the chopped pecans (if using) and the remaining 6 ounces of chopped bittersweet chocolate evenly throughout the batter.
- Pour and bake: Pour the batter into the prepared baking pan and spread evenly. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out with moist crumbs but not wet batter.
- Brush bourbon on brownies: Upon removing the pan from the oven, immediately brush the warm brownie surface generously with the remaining 1/4 cup of bourbon to add moisture and flavor.
- Cool brownies: Allow the brownies to cool completely in the pan on a wire rack before removing them using the parchment overhang.
- Prepare bourbon buttercream: In a mixing bowl, beat 1/2 cup of unsalted butter at room temperature until creamy. Gradually add the confectioners’ sugar and continue beating until smooth. Add the Biscoff cookie butter and 1 tablespoon bourbon, and beat until fluffy and well combined.
- Make chocolate glaze: In a small saucepan over low heat, melt the semisweet chocolate chips with 3 tablespoons of unsalted butter, stirring constantly until smooth and glossy. Remove from heat and let cool slightly.
- Assemble brownies: Once the brownies are cooled, spread the bourbon buttercream evenly over the top. Drizzle or spread the chocolate glaze over the buttercream for an elegant finish. Allow glaze to set before cutting.
- Serve and store: Cut into squares and serve. Store any leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to 5 days.
Notes
- You can omit the pecans if you prefer nut-free brownies.
- The bourbon flavor bakes out somewhat, but brushing warmed bourbon on top intensifies the taste and moistens the brownies.
- Make sure the brownies are completely cool before frosting to prevent melting the buttercream.
- If you want a stronger bourbon flavor, adjust the amount brushed on top or added to the buttercream.
- The chocolate glaze adds a shiny finish and extra richness, but can be omitted if desired.
- Store brownies in an airtight container to maintain freshness and moisture.
