In the US, sweet cream is cream that hasn't been cultured (as opposed to sour cream). It's usually used in the context of butter since all heavy/whipping cream is assumed to be sweet cream unless specifically stated. Since the poster is from Poland and there's no other sweetener in the recipe, maybe they mean cream sweetened 30% by weight with sugar?
