What you need:
1 Tablespoons Water
1 Tablespoons Vegetable Oil
1/8 teaspoon vanilla (optional)
Dash of salt
1 Tablespoons Cocoa powder
2 Tablespoons Sugar
2 Tablespoons Flour
1 Small handful of chocolate chips (optional)
1. Add the water, oil, vanilla, and salt to the mug and mix. Then add cocoa powder, whisk well. Add sugar, whisk well. Add flour, whisk well, until no clumps remain.
2. Microwave on high for 60-90 seconds. You may have to microwave it longer or shorter, depending on your microwave, but the brownie should still be moist in the center when done.
That's it! Let it cool slightly, and enjoy your two-minute brownie!
