Ingredients

Scale
  • 1 cup unsalted butter, melted
  • 8 oz bittersweet chocolate, chopped
  • 1 cup granulated sugar
  • 1/2 cup brown sugar, packed
  • 3 large eggs, room temperature
  • 2 tsp vanilla extract
  • 2 tbsp instant espresso powder
  • 1/4 cup brewed strong coffee, cooled
  • 1 cup all-purpose flour (or almond flour for gluten-free)
  • 1/2 tsp salt
  • 1/4 tsp baking powder
  • For the Whiskey Glaze:
  • 1 cup powdered sugar, sifted
  • 23 tbsp Irish whiskey
  • 1 tbsp strong brewed coffee
  • 2 tbsp unsalted butter, melted
  • Pinch of salt

Instructions

  1. Preheat oven to 350°F (180°C). Line an 8×8-inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a medium saucepan over low heat, melt butter and bittersweet chocolate, stirring until smooth. Remove from heat and let cool for 5 minutes.
  3. In a large bowl, whisk together granulated sugar and brown sugar. Add eggs one at a time, whisking until thick and pale. Stir in vanilla extract.
  4. Stir in instant espresso powder and brewed coffee.
  5. Slowly pour the cooled chocolate mixture into the egg mixture, whisking just until combined.
  6. Sift together flour, salt, and baking powder. Fold into the wet ingredients using a spatula until just combined.
  7. Spread batter evenly into prepared pan. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  8. Place pan on a cooling rack and let brownies cool for at least 30 minutes.
  9. For the glaze: In a small bowl, whisk together powdered sugar, Irish whiskey, brewed coffee, melted butter, and a pinch of salt until smooth. Adjust thickness as needed.
  10. Lift cooled brownies out of pan using parchment. Drizzle glaze generously over the top and let set for 10–15 minutes before cutting into squares.

Notes

For gluten-free brownies, substitute almond flour or a 1:1 gluten-free blend. For dairy-free, use plant-based butter and dairy-free chocolate. Omit whiskey in the glaze for a kid-friendly version. Chill brownies before slicing for neat squares. Glaze can be made ahead and stored in the fridge. Add nuts or berries for variations.
