I have an order for a grooms cake for a wedding for May 24... nothing special so it seems but still lots of questions lol. The color the couple has chosen is yellow and blk... as I do not do wedding cakes they ordered the wedding cake from walmart but was unhappy to discover that walmart will not do a yellow/blk wedding cake... The groom (my coworker) ask if i would do a grooms cake to be served at the private reception... Asking what he enjoyed as ideas for a them he said dancing....
My idea is a yellow and blk check top of a sheet cake with a dancing bride and groom topper on top... I would like the sides of the cake to be done in yellow buttercream, and the check top to be done in mmf. I have never used mmf but once and used it uncolored as practice... so... I need lots of help.

1. Will I need to make 2 batches of mmf and color one yellow and one black?

2. At what stage do I add the coloring???

3. Any other ideas for a really nice looking 12x18 sheet cake with a yellow and black theme is welcome

I am giving this cake as a gift as he is a USDA (united states Dept. of Agriculture) inspecter at the poultry plant where I work. I want this cake to be awesome looking and tasting as I feel sure it will open me to many more paying customers... Sorry so long and thanks for all the help and ideas!!!

I just made cookies with red MMF. I kneaded in the color after the fondant was made and sat overnight. I then let the red fondant sit overnight for the color the set. It gets deeper and more instense.
Hope this helps.
