Add maida or all purpose flour,coco powder, sugar, baking soda and salt in the mug and mix it well
After that add oil, milk and vanilla essence
Mix well and make sure there are no lumps
The batter should be creamy and in flowing consistency
Microwave it for 2 minutes
The cake will rise over the top but went down a bit when the microwave turned off
Take the mug out and top it with your favorite ingredient like choco chips/gems/nuts/choco syrup
I didnt find anything so I used chocolate and strawberry syrup over the cake
It was very yummy
Cooking Tips:If you want a healthier version then you can use wheat flour instead of maida
I had tried it and result was good
If you want to bake the same cake in OTG : Preheat oven to 185 deg C and bake the cake for 10-12 mins at the same temperature
It may take even 15 mins so check it after 12 mins and then bake accordingly
