Add butter to a mug or a glass and microwave for 10-15 seconds, until butter is completely melted. Stir in cocoa until completely blended. Stir in water until blended. This order is important to keep the brownie batter from clumping. Stir in sugar and then flour.

*If you want to use unsalted butter, just add a pinch of salt when you add the flour.

Microwave according to how gooey/fudgey you want your brownie.
