Directions:
- Preheat the oven to 175°C (350°F).
- Butter the sides and bottom of a 23cm x 33cm baking dish with butter. Cover the tray with parchment paper.
- In a bowl, whisk the flour, salt and cocoa powder.
- Place the chocolate, butter and instant espresso powder in a large bowl and place over a saucepan of simmering water, stirring occasionally, until the chocolate and butter are completely melted.
- Turn off the heat and leave the pan over the water and add the sugars.
- Whisk to combine well and remove the bowl from the pan. The mixture should be at room temperature.
- Add 3 eggs to chocolate mixture and beat until combined.
- Add the remaining eggs and beat until combined.
- Add vanilla and stir until combined. Don’t overheat the mixture at this point so the brownies don’t clump together.
- Sprinkle flour mixture over chocolate mixture.
- Using a rubber spatula, stir the flour mixture into the chocolate until very little flour mixture appears.
- Pour the mixture into the prepared pan and smooth the top.
- Bake in the middle of the oven for 30 minutes, rotating the pan halfway through, until a toothpick inserted in the center of the brownies and a few moist crumbs come out.
- Let the brownies cool completely, then remove them from the pan using parchment paper.
- Cut into squares and serve.
Enjoy!
