I made this for my sweet friend's b-day. It's brownie cake with marshmallow buttercream filling. Bottom tier is 3.5", top tier is 2". The flower/decorations are all out of modeling chocolate. Probably not too smart as my hot hands kept ruining the flower...but once it set up in the fridge, it looked great. Next time I'll make it with gumpaste...but it sure tastes better this way! My second mini cake!! Thanks for looking!
