When it comes to describing something that is in layers, there are a number of useful synonyms that can be employed. One possibility is the phrase "stratified," which could describe anything from rock formations to a cake topped with icing. Another option is "layered," which is perhaps the most direct and straightforward synonym. However, those looking for a more poetic or dramatic turn of phrase could try "tiered," "flaked," "stacked," "peeled," or "feathered." Depending on the context in which the phrase is being used, any of these synonyms could help to add depth and nuance to a description.
