"Plăcinta cu mere e bună!"

Translation: The apple pie is good!

[miacomet]

Since accusative nouns after prepositions often don't get the article, is it possible to translate this as "The pie with the apples is good" too?

[lulubeck]

The slow version says bun.

[Sammatazz]

She totally does

[gadee2]

"The apple cake is good." Is this really incorrect?

[paeonia001]

A cake is not a pie, generally.

[David-Herron]

"Placinte" means something completely different from "tort".

For an example, there is a restaurant in Romania, La Placinte, which offers traditional Romanian food. The relevant page from their menu is:

https://laplacinte.ro/ro/pages/menu/13/

THAT is what's meant by Placinte. There are pastry shops everywhere that sell this stuff on the street.
