Milestone Birthday Cake Ideas _ If you're celebrating a special or milestone birthday, then you could make a cake in the shape of the age like a number 1, 16, 30, 50, 100, etc. Depending upon how many guests you plan on serving will help dictate the ultimate size of your age cake. Although this is a great idea, this type of cake isn't something that you would want to create year after year. It's best kept in reserve for a very special age.
Bottom Line: When you're trying to come up with some birthday cake ideas, brainstorm! Make a list of what the person is most interested in, their likes and dislikes, the era of their birth, along with considering their profession, hobbies, and age as possibilities to help you create a that cake masterpiece.
