My niece loves the movie titanic and asked for a titanic cake. Not the most uplifting cake for an 11th birthday but it forced some creativity... The ship and ice bergs are made out of Rice Krispies and covered in fondant. The rest is buttercream.
Happy Birthday to My cousin Lauren. I can't believe you are 21!
There are a number of drunk barbie cake ideas on Pinterest, I personalized it by adding Lauren's boyfriend as the action hero coming in to help as his girlfriend is puking sprinkles into the fondant toilet.... Fun!
