First, you would need a tall microwaveable mug/cup. It will overflow if the mug/cup is not tall enough. Spray the inside of the mug with some non stick vegetable oil.
Measure in about 4 tbsp of flour.
Then add in about 4 tbsp of Milo. If you do not want to use Milo, you can use any type of chocolate powder that you like.
This is then followed by 4 tbsp of sugar.
Mix everything together well.
Next, crack in one egg.
Then, add in 3 tbsp of milk.
Measure in about 3 tbsp of oil
Pour in some semi sweet chocolate chips and mix everything together.
This is how it should look like once you have mixed everything together well.
Pop it into the microwave for about 3 minutes on high.
This is how it looks like after 3 minutes in the microwave. See how nicely the cake has risen up. Oh, it smells great too, by the way :P
Give the mug/cup a few good shakes and it should slide out without any problems.
This is good for two servings. I cut the cake into two and served it up with a dollop of whipped cream. It would taste yummy too if it was served up with some vanilla ice cream. It's amazing how something so yummy could be made in such a short time and all you need is some basic ingredients, a mug and a microwave!
