Dangerous Chocolate Cake

I got an email from my mother today with "Dangerous Chocolate Cake" in the subject line, and in spite of my trepidation at the possibility of learning that chocolate cake is now some form of terroristic threat, I opened it anyway. Then I spent the next ten or fifteen minutes making this.>
It's chocolate cake that you can make really fast with basic ingredients and the microwave. Here is the recipe:

4 tablespoons (60ml)flour (use self-rising or add 1/2 tsp pracek do peciva)
4 tablespoons(60ml)sugar
2 tablespoons(30ml)cocoa
1 egg
3 tablespoons(45ml)milk
3 tablespoons(45ml)oil
3 tablespoons(45ml)chocolate chips (optional)
A small splash of vanilla extract
1 large coffee mug

Add dry ingredients to mug, and mix well. Add the egg and mix thoroughly.
Pour in the milk and oil and mix well.
Add the chocolate chips (if using) and vanilla extract, and mix again.
Put your mug in the microwave and cook for 3 minutes at 1000 watts.
The cake will rise over the top of the mug, but don't be alarmed!
Allow to cool a little, and tip out onto a plate if desired.

I opted to tip it out onto a plate and slice it. It didn't turn out as sweet as I would have liked, so I microwaved a little butter, cocoa, powdered sugar and milk in a mug for about a minute and poured it over the top. It is in fact, quite enough for two or maybe even three people, especially if you served it with ice cream. (What's in the photo is about half of the cake) Of course, to self-medicate after a bad day, you could always just stick a knife handle into the cake while it's in the mug and fill the hole up with chocolate syrup and eat it all yourself. Bad, bad World! Poor, poor me.
