This is the hardest part, it's a little time consuming but fun, my colors are pretty pastel....you could TOTALLY go brighter than this....but I was a little unsure of how they'd taste if the colors were darker
Cool for 10 minutes, remove from pans, cool COMPLETELY on wire racks and even out the bottom layer using a knife or the string method so the top layer sits nicely on top of the frosted bottom layer and it doesn't try to slide off (yes, from personal experience)....then frost some more with your favorite frosting.
Made these baby's at the same time for a friend's get-together, the cake tasted great! I think they were impressed :)
Now it's time for the variations..... Holiday color combinations......endless possibilites! Sports team colors....remember you can go WAY brighter/darker/whatever! Have FUN!
