Remember the time I made a cake in a mug and from the microwave?? Yup that thing looked like rubber!!
But lord and behold!!! Someone has invented Cake in a can!!
A lot of flavors are available: chocolat, coffe, birthday cake, wedding cake (!) and Christmas.
Apparently, it's super easy, you just have to add water and the cake baked in the can! I guess you have to put it in the oven, but still simple.
You can buy one for $8.75 at http://www.thisiswhyimbroke.com/chocolate-cake-in-a-can
