Ingredients

Scale
  • 1 cup unsalted butter, melted
  • 8 oz dark chocolate, chopped (at least 70% cocoa)
  • 1 cup granulated sugar
  • 1/2 cup brown sugar
  • 3 large eggs, room temperature
  • 1/4 cup brewed strong coffee
  • 2 tbsp Irish whiskey
  • 2 tsp vanilla extract
  • 3/4 cup all-purpose flour
  • 1/4 cup unsweetened cocoa powder
  • 1/2 tsp salt
  • For the Whiskey Glaze:
  • 1 cup powdered sugar
  • 23 tbsp Irish whiskey
  • 1 tbsp brewed coffee
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy lifting.
  2. In a medium saucepan over low heat, melt butter and chopped dark chocolate until glossy and smooth. Let cool for 5 minutes.
  3. In a large bowl, whisk together granulated sugar, brown sugar, and eggs for about 1 minute until pale and slightly thickened.
  4. Add brewed coffee, Irish whiskey, and vanilla extract to the egg mixture. Whisk until combined.
  5. Slowly pour the cooled chocolate-butter mixture into the egg mixture while whisking. Batter should be shiny and thick.
  6. In a separate bowl, sift together flour, cocoa powder, and salt. Gently fold into the wet mixture using a spatula. Do not overmix.
  7. Pour batter into prepared pan and smooth the top. Bake for 28-32 minutes, until edges are set and a toothpick inserted comes out with moist crumbs.
  8. Transfer pan to a wire rack and let brownies cool completely, about 1 hour.
  9. For the glaze: In a small bowl, whisk together powdered sugar, Irish whiskey, brewed coffee, and a pinch of salt until pourable but thick.
  10. Lift cooled brownies out of the pan using parchment overhang. Drizzle glaze over the top and let set for 15 minutes.
  11. Slice into 16 squares and serve.

Notes

For gluten-free brownies, use a 1:1 gluten-free flour blend. For dairy-free, substitute vegan butter and dairy-free chocolate. Chill brownies before slicing for cleaner cuts. Adjust whiskey in glaze to taste or omit for a kid-friendly version. Use high-quality chocolate for best flavor. Brownies can be frozen (unglazed) for up to 2 months.
