Start with Flour, sugar and cocoa powder in a coffee mug and mix. (Using a fork is easiest)
Then add egg, mix well until all blended.
Add the vegetable oil and milk and mix very well until completely blended.
Put in microwave for 3 minutes or until it is done to your liking!
You can add different things to it and make it your own! Add a mashed banana with 1 tablespoon more of flour. Or add chocolate chips, skor bits, or leave out the cocoa powder and add 1 tablespoon more of flour as well
