Preheat the oven to 350°F.
In a medium saucepan, melt the butter and chocolate over low heat, stirring until smooth. Remove from heat and let cool slightly.
1 cup (8 oz.) butter, 4 oz. dark chocolate (at least 70% cacao), broken into pieces
In a large bowl, beat the eggs on medium speed for 2 minutes. Stir in the cooled chocolate mixture, then add the sugar, flour, salt, peppermint extract, and bourbon. Mix until fully combined.
4 large eggs, 2 cups granulated sugar, 1-1/2 cups all-purpose flour, 1/2 tsp. table salt, 1/2 tsp. peppermint extract, 2 tbsps. bourbon
Pour the batter into a greased 9x13-inch pan. (I like to line mine with parchment paper for easy removal.) Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Let cool completely before cutting—if you can wait.
While the brownies bake and cool, make the candied pecans. In a small saucepan, melt the butter over low heat. Stir in the brown sugar until combined. Add the pecan halves and cook over low heat for 2–3 minutes, or until the mixture darkens slightly. Remove from heat and let the pecans cool for about 15 minutes, until the sugar hardens. Break into pieces for garnish.
1 tbsp. butter, 2 tbsps. light brown sugar, 1/3 cup pecan
For an authentic Mint Julep presentation, splash a little bourbon onto each serving plate and place a brownie slice on top. It’s optional, but it really adds something. Garnish with freshly whipped cream, candied pecans, and a sprig of mint.
