If you remember from last year, my daughter kindly provides me with a detailed sketch outlining the shape, color scheme, and flavors for her birthday cake each year. This year the theme is hearts (layer shapes), colors are white, pink and red, the ten layers include chocolate cake, coffee ice cream, vanilla soy ice cream, and homemade chocolate frozen yogurt.
The problem with ice cream cakes is that they spout leaks if you are not quick enough with the pastry bag while decorating the outside. In this case, I just stuck it back in the freezer for awhile and covered the coffee ice cream drip with white frosting later.
