Once upon a time, I had a friend named Allison. She would e-mail me months in advance of her own birthday, just to make sure I kept the date clear for making her birthday cake. She was very specific about her birthday cake demands. Her husband would always nervously call me with these crazy ideas of hers. This particular year, on her 30th birthday, she requested a cake with as much candy, sprinkles, and marshmallows as I could get on one cake. So, I made this 2-layer chocolate cake, filled the middle layer with buttercream icing, mini-marshmallows, and pink sugar sprinkles. Then I decorated the top with more icing, spelling out "Happy Birthday." I spelled out her name and age in candy letters, lined the bottom border with more marshmallows and peanut M&Ms, and topped it with more sprinkles of different shapes and colors -- pink and purple sugar, pastel flowers and pink & white hearts. She absolutely loved it!
