The butterflies and ribbon are completely edible. They are both made of gum paste.
Sadie's mom only had 3 requests for this cake. She wanted it to be pink, white and it had to have butterflies on it. The 6 inch top tier is lemon pound cake filled with alternating layers of lemon curd (an intense lemon filling) and lemon swiss meringue buttercream frosting. The 10 inch bottom tier is a cream cake filled alternating layers of raspberry puree and vanilla swiss meringue buttercream frosting.
