Does anyone know the name brand of buttercream icing wal-mart uses on there cakes?

I've never had a walmart cake before but I think alot of the commercial bakeries use something called bettercreme or something like that?

Bettercream is a product to replace whipped cream, not buttercream. I am not sure what Walmart uses, I would imagine it is Dawn's buttercream. Dawn is a large scale bakery manufacturing company that many places use for their mixes and premade ingredients. That is just a guess.

Rich's Betttercreme

Bettercreme is their Whipped icing.
Buttrcreme is their Buttercream HTH

Hmmmm... not sure that bucket frosting can be called BUTTERcream, when the closest it has ever come to butter is being delivered on the same truck!
