Easy peasy. In collections search for either "heart" or "soot." One is either a sponge cake or something less. The other is either a gingerbread house or something less. As the item that is given when the collection is combined. (brown print in the gold bar right above the collection items)

If you have either the cake or the house you have not yet updated.
