If I saw a baker advertising specifically that this cupcake's frosting is homemade, I would wonder if other parts of the cupcake weren't or if her other cupcakes use store bought frosting or something. Like, okay, so these specific components were 100% homemade...does that mean the rest is a cake mix? Pumpkin puree I can see bragging about having made yourself, since you do have to gut a pumpkin for it, but the other stuff just makes me think of how McDonald's chicken nuggets "are made WITH all white meat chicken."
OMG, LOOK!!

...It's a siggie.
