Okay, so it wasn't as easy as it seemed... Maybe I should have used different colourants, or a white cake mix, because the colours didnt stick that well... They didnt look bright. Not to mention I think the red was off... It smelt funny, and turned the cake purple (instead of red,... duh). Tried making the layered version, and it went horribly wrong, so i decided to just do it in the same container... It looked better and tasted alright, but it still is far from perfect xD I also made a carrot and orange roll, and that tasted delicious! VICTORY IS MINE!!! (Sorry about the crappy pics, but they were taken with my phone, with bad lighting).
