i need some ideas for a housewarmin cake, and pictures would be nice, oh and also i only want up to four different colours in the cake not including white...

if you go to the galleries tab and do a search for house warming, there are a lot of photos.
a simple house shaped cake with colored doors and shutters and roof would be nice.

can i ask? why four colors?

only four colours because i only have a couple of the paste food colours and i don't have the time to go out to the nearest place they sell them for more...

You could always mix the colors you have to make new ones

ohhh i see. yeah, you could mix colors. you could also add cocoa to the buttercream or strawberry juice and other things to color. all sorts of combinations, and yummy ones at that!

How about a big key/set of keys colored yellow, or gold.
