Hi everybody! I'm planning my first tiered cake for my daughter's 4th birthday. I'm going to be using the Wilton Romantic Castle set, b/c she's having a princess party. I'm not sure what type of cake mix (batter) to use. She is a plain-jane girl, just yellow or white cake is fine. I'm just concerned about holding up the weight of the tiers and castle pieces. Does anyone have any suggestions for this? Thanks so much!! Any recipes would be great!
