Run out of milk to go with breakfast? Instructables user bongodrummer has a solution:

Oh no, there’s no milk left for my cereal! No problem – begin emergency breakfast cake procedures.

I have been developing this super simple, versatile little beast for many years now (well, since I left home and started tinkering with food stuffs in a way that was ‘misunderstood’ at my parents abode). The main ingredient of the breakfast cake (BC) in this particular example is muesli, but I have had good success with a number of other cereals.
