This Phineas & Ferb Birthday Cake is a simple 9×13 pan of boxed yellow mix. The icing was made from a simple buttercream recipe from allrecipes.com. The icing was separated into individual bowls & colored with Wilton’s icing gels, then I drew the image of Phineas freehand using piping made simply from Ziploc bags. My 7-year-old son & his friends absolutely loved it!
