Chocolate cake in 5 minutes. A delight! 

This is just one of many ways to make a chocolate cake. You can of course vary the ingredients.
You can heat cocoa with the glass of milk instead of chocolate pieces.
For the oven: I light the bottom 10 to 15 minutes and add the top the other 10 to 15 minutes.
Super good! We barely finished the cake and they want another one!
