Ingredients
3 tbspcocoa powder
4 tbspsugar
1egg
3 tbsp / 2 tbspflour and butter
Instructions
1
Whisk the melted butter, sugar and egg together directly in the mug until smooth, making sure the butter is not hot enough to scramble the egg.
2
Fold in the cocoa powder and flour until just combined, overmixing at this stage is what makes microwave brownies turn tough and rubbery instead of fudgy.
3
Microwave for 60-90 seconds, checking at 60.
4
Pull it out while the centre still looks slightly underset, it firms up as it cools, and overcooking is the most common mistake.
