Classic Dark Chocolate Brownies

Preheat your oven to 175°C and line a 20cm square baking pan with parchment paper.

Melt the butter in a large microwave-safe bowl and stir in the sugar until well combined.

Add the cocoa powder, eggs, and vanilla extract to the bowl and whisk vigorously until the batter is smooth and glossy.

Gently fold in the flour and salt using a spatula until just combined, being careful not to overmix.

Spread the batter evenly into the prepared pan and smooth the top.

Bake for 25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs.

Cool the brownies completely in the pan on a wire rack before cutting them into squares.
