We just had a cake for my grandsons baby shower and it was wonderful. It was a white 1/4 slab with fresh blueberries. The cake was very tasty and everyone raved about it. It was decorated so cute with a… soother, booties and a take home tether/rattle for the baby. I would highly recommend and will certainly order again when I need a special cake!
