The wedding flowers were Peonies, so when I googled Peony wedding cake, I came across this pretty little cake...
Below is my take on this cake - the bottom two tiers were Styrofoam and the top was vanilla cake and the whole thing was covered with vanilla decorator frosting like my mom used to make. :) The cake was fairly easy to do with the messier frosting technique, and I think once I got the flowers on it, it turned out pretty good (especially considering this was my 2nd wedding cake ever!).
The final picture is of the cake and cupcakes at the reception site, I thought it all looked very nice once it was all put together!
