I want to get a half sheet cake for my daughter's third birthday that's tasty and not too pricey. I say old fashioned because I'm looking for a normal moist yellow cake (maybe even - gasp - box cake) with preferably whipped frosting (versus buttercream, which I find too sticky and heavy.) I've gotten a lot of recs for Pathmark, but they only take orders in person which is hard for me and I've also heard that they are often not on time when you need to pick them up. We don't belong to Costco. Any other ideas of where I can order a cake like this?
