This cake was made using buttercream frosting, and marshmallow fondant for the Nemo figure. The blue buttercream gradually gets darker from the top to the bottom layers.
I made Nemo from the fondant, & used black edible marker for the details. This was the 1st time that I've used marshmallow fondant. It was pretty sticky and messy to make, but I really like the taste better than the pre-packaged fondant. I hadn't made any figures like this before, so I was really happy with how it turned out
