For my mom's birthday, I wanted to throw a nice luau for her, complete with a Hawaiian style cake. This is such an easy way to decorate a cake, with beautiful results! First, bake any kind of cake you wish, and frost it. Then get Pepperidge Farm Pirouette Cookies and break them into different sizes. Place them all around the outside of the cake. It makes an awesome bamboo border!
Then place your flowers around the cake. You can use fresh or synthetic. I ordered these plumerias online from Oahu, and they turned out great!
