There is no definite answer to this because cake costs vary, regardless of theme. Many factors affect or influence pricing, and these include size, availability of ingredients, materials used, type of cake and how complicated it is to bake, complexity of the design, and the skill level of your baker or cake maker. For example, there are types of cake and cake flavors that require more steps and more time to make, as well as those that use more expensive or hard-to-find ingredients. These cakes would naturally be more expensive. Fondant cakes would also cost more than those that just use buttercream frosting. Even more so if you ask Toy Story figures or characters to be made by hand using gumpaste. This would require a lot more time and skill. Moreover, bakers and cake makers with more years of practice and experience would charge more than those who are just starting out.
