The bottom tier was vanilla cake (white and purple marbled) with raspberry/blackberry filling and buttercream frosting. Then, the top tier was chocolate cake with vanilla filling and buttercream frosting. Everything was homemade (of course) so the cake took a while to make and construct. I made the butterflies out of white fondant then painted them with zebra stripes, I also made the "16" square out of fondant and painted that as well. Altogether, the cake was challenging but really fun!
I get inspired by looking at people's cake pictures so I hope this inspires you to create something :)
