This is my first flower pot cake. I made it for my mom's birthday. She doesn't like MM fondant so I used buttercream icing. Next time MM fondant for sure (for the pot) to give it a more realistic look. All flowers, leaves and sign are fondant. White cake with custard filling. Only problem is the cake fell apart 5 minutes from my mom's!!!!! Lots factored into this disaster - 2 hr drive, too many dowels (cake was sliding from filling), very bumpy detour last 1/2 hr of drive!
