How to make this wonderful cake!
Just buy regular chocolate cake mix from the grocery store,
Bake it of course,
Use a frying pan / lid / a circle shaped object to give the cake a circle shape
Cover all you can with chocolate frosting,
Put chocolate chips all over the frosting,
Make a circle of 8 whipped cream 'squirts',
Put a cherry / strawberry on each 'squirt'.
Put a candle in the middle (which I forgot :L),
--The cake GLaDOS tempts you with in Portal.
