Yikes! I cut all the circles out of two 9x13's, since this was just a practice cake. What a pain! And I used an enhanced white cake mix, which turned out crumbly as heck and a pain to crumbcoat. And I'm not happy with the angle of the top layer. But other than that -- what a blast! This was a whole lot of fun, and I learned a ton about what-not-to-do. Stayed up 'til 2:30 working on it. Woke up at 6:30 to finish it. Yes, I'm addicted. All fondant over buttercream.
