Perfect Brownies

Preheat your oven to 170°C (350°F) on both top and bottom heat.

Melt the chocolate with butter using a double boiler or short bursts in the microwave. Let it cool slightly.

Whisk the eggs with sugar for 2–3 minutes until light and fluffy. Add vanilla.

Pour in the chocolate mixture and fold it in gently.

Sift together the flour, cocoa, and salt. Fold everything together quickly with a spatula—don't overmix or you'll end up with cake instead of brownies.

If you like, stir in nuts or chocolate chunks. Pour the batter into a parchment-lined pan.

Bake for 25–30 minutes. The center should jiggle just slightly when you shake the pan—that's exactly what you want.
