I made this for my son's 9th birthday which falls on July 4th weekend. He designed the cake idea on paper and I followed his lead. To make this I baked two 9x13"s, filled and layered them before I carved the cake into the shape of a 9. (Note: To make the template for the 9, I simply typed in a "9" in MS Word on my PC. Then I printed and enlarged it on my copy machine until it was 13" long. Worked great!) I may try to add sparkler candles or something to this more Oomph! Thanks for looking.
