Melt the butter in high for about 30 to 40 seconds. Add the sugar, cocoa and vanilla in that order and mix well.
Add the eggs, slightly whipping after each one. Add the flour and mix well.
Grease a microwave safe dish and spoon in the brownie mixture. Cook on high for 4 to 5 minutes (the more powerful your microwave the less time it takes). Let rest for 10 minutes before cutting.
Tip
When you take the brownies from the oven the centre will look undone, but it keeps cooking when resting. And if you leave them overnight in the fridge, the next day they will be even more consistent.
Substitution
This recipe also works well with 3 eggs, 100g butter, 65g to 125g of flour, 45g to 65g cocoa. So, don't worry if you don't have enough of any of the ingredients, but make sure not to change more than one amount at a time!
Other ideas
You can also stir in 120g of nuts, or 60g of nuts and 80g chocolate chips, or only chocolate chips! Or you can sprinkle some chopped nuts or pistachio nuts (tastes great!) on top before microwaving.
