This was my first attempt at a topsy turvy cake and I was surprised at how subtly easy and subtly difficult it was at the same time. Vanessa wanted a unique cake for her 16th birthday. She wanted teals and greens and a touch of black. Vanessa's birthday was 09-09-09 which is pretty cool so we wanted to highlight that as well. The top tier was a Cookies & Cake cake (vanilla cake layered with buttercream and crushed oreos). The middle tier was a Brownie Lovers cake (chocolate cake layered with rich chocolate ganache and a layer of actual brownies in between the chocolate cake). The bottom tier was a Mint Chocolate Chip Cake (vanilla cake with chocolate chips baked in layered with lightly flavored mint buttercream with chopped chocolate chips).
