I have been asked to make a watermelon cake for this weekend for a little girls birthday. She wants all buttercream. HOW do I get green butter cream on the sides and red/pink on the top without it looking terrible where the two colors meet? She wants it to look like someone sliced a watermelon round, so no borders around the top or bottom edge.

Would it be better to ice all in white and use food color spray on the sides and center of the top and make a stencil for the seeds? I don't have an airbrush.

She also requested if I could to take a "slice" out of the watermelon and have it sitting to the side decorated. How do I do that without the whole thing falling apart on me?

I am taking ALL Suggestions! Any help is greatly appreciated!

AI have a sliced watermelon cake in my avatars it was pretty easy just stack the cake cut in half than mix green , white and red colors . I used the same size star tip and went all around the cake in the colors needed. I than laid the added slice and decorated it. I used rasins for the seeds because that's what I had at home you could use chocolate chips if you wanted to.was pretty easy to do.

I've had this cake in my favorites for some time now, even though I haven't tried it

I think you could pull off this look with a light green crusting buttercream/viva paper towel method, then when dry use a darker green (gel/vodka mix) to brush on the stripes and blot it to make the stripes more irregular.

I've been waiting for an oppotunity to make this myself!

Let us know how it turns out!

This is the picture she sent that she wants it to look like but she wants BC instead of the fondant.

I work mostly in buttercream.  Here is what I suggest.  Frost the top and inner slice pink.  Frost the outer edge green, being careful where it connects to the pink/red.  Pipe a white border where the pink meets the green.  When it is complete, add the black details.

As far as striping the green on the outside...you can pipe with a 12 tip with the 2 different color greens, then viva method the sides.

Good luck!

This is a watermelon cake I made last year, before I had any experience with fondant.

I used this recipe:  http://birdonacake.blogspot.ca/2012/05/watermelon-flavored-cake.html

It tasted just like watermelon, and looked pretty good, too, for one of my first cakes.  :-)  I used the icing from the recipe, and when it was firm from being in the fridge, I lightly painted it with kelly green colouring, to get the impression of stripes on the "rind".  The seeds on the top are mini chocolate chips pressed into the icing.

I know I could do it better now, but everyone was pretty impressed at the time (as was I).    You could also shape the cake a bit more rounder to get more of an impression of a watermelon, but I was just happy at the time to make a cake.

Now, having said that, I'm not sure how to get the slice without covering it in fondant...unless you cover the whole piece in buttercream.  Which is a possibility.
