Ingredients
Method
- In a microwave-safe bowl, melt the butter with both sugars. Stir in the cocoa powder and salt.
- Whisk in the egg and vanilla until the batter is glossy and smooth.
- Fold in the flour until just combined. Do not overmix.
- Pour into a parchment-lined 6-inch pan. Air fry at 325°F (160°C) for 12 to 14 minutes.
- Cool in the pan for 10 minutes, then lift out and cool completely on a wire rack before slicing.
Notes
Cooling the brownie fully is non-negotiable for clean slices and that dense fudgy center. If you’re in a hurry, pop it in the fridge for 15 minutes after the initial cool-down. It sets the butter and makes cutting a breeze.
