My daughter wanted a blue ocean cake for her third birthday. I love ombre cakes, and thought it would be a perfect way to represent the subtle blue hues of water. But it still had to be fun & playful for a child. So, I made the bottom tier with ombre mermaid scales, fading from light blue to dark blue. The top tier has golden seaweed, bubbles, waves, & a little mermaid tail splashing out of the top. Each tier was made from 6" layers of vanilla buttermilk cake, died in an ombre blue pattern (from light blue to dark blue), with blackberry filling & almond SMBC. My six year old was jealous. :-)
