The Most Dangerous Cake in the World

I got this recipe from a many times forwarded e mail my mom sent me. I tried it and loved it, but it really is the most dangerous cake in the world because it's small, easy and so fast.

5 Min. Mug Chocolate Cake

4 Tbsp plain flour
4 Tbsp sugar
2 Tbsp baking cocoa
1 egg
3 Tbsp milk
3 Tbsp oil
3 Tbsp chocolate chips
a small splash of vanilla
1 coffee mug

Add dry ingredients to mug and mix well.
Add egg and mix thoroughly.
Pour in milk & oil and mix well
Add the chocolate chips and vanilla, mix

Put mug in the microwave and cook for 3 minutes.
(The cake may 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 just eat it out of the mug)
Can be shared between two but...why?
Have a large glass of milk on hand for this one.

(sorry I don't have a picture, it doesn't look very good even though it tastes good)
