A princess theme is a commonly requested type of birthday party for young girls, and a themed cake is a must at any princess party. The popular three-dimensional birthday cakes look difficult, but a Bundt cake makes this kind of princess cake possible for any skill level. The Bundt cake serves as the skirt of the dress, requiring no carving to achieve the look. All of the guests at the princess party will marvel at your sugary masterpiece.
Pour the cake batter into a well-greased Bundt pan. Use either a boxed cake mix or a homemade cake recipe for the batter. Bake the cake according to the instructions.
Let the cake cool for 10 minutes before removing it from the pan. Let it finish cooling completely on a cooling rack. Place the cake on the serving platter or cake board once it is cool.
Tint buttercream frosting to the color you want for the princess dress. Pink and purple are popular options. Use an offset spatula or knife to spread the tinted icing on the cooled Bundt cake.
Squeeze a generous amount of the buttercream frosting into the hole of the Bundt cake to hold the doll in place. Press the clean doll into the hole. Smooth the frosting and remove any excess from the hole.
Place a small amount of the tinted buttercream icing in a pastry bag with an icing tip attached. You can use either a round tip or a star tip if you prefer the look of stars. Pipe the bodice of the dress onto the doll using the selected icing tip.
Add accents to the dress with icing or candies. Use the same color of icing or tint more icing in an accent color. Accent ideas include dots, stars, swags or piped lines.
Choose a plastic doll that resembles a princess for the best results.
