Get out 2 mugs. Make sure the smaller one is for adding the ingredients only!
Put 1/4 mug of sugar in the mug.
Transfer to the larger mug.
Now put 1/4 mug of flour in the mug.
Add a pinch of salt.
Add 2 tbsp of cocoa powder.
Now add 2 tbsp of olive oil or rice bran.
Add 4 tbsp of water.
Now mix!!! If a little stodgy, add more water.
It will look rather unappetising!
Put in the microwave and heat on high for about 1 min 30 secs.
Voila. Here is your brownie in a cup. You could also add ice cream to finish it off!
