Translation: My cookies are tasty.

Yes, they are! I just made some ginger molasses cookies the other day, and they came out super good.

"moje ciastko to smaczne." Please, would this be correct for " My cookie is tasty".

[Jellei]

No. Firstly, we have plural "ciastka" (or "ciasteczka" if we go with the word this course teaches), not singular "ciastko/ciasteczko" here.

Secondly, you can only use the construction with "to" if there are noun phrases on both sides. For example a rather absurd sentence "My cookies are tasty cookies" could be translated as "Moje ciastka to smaczne ciastka".

But if you just have a standalone adjective (are tasty), you need to use the verb. So "Moje ciastka są smaczne".

Just to be clear, są is "is" for plural, and jest is "is" for singular?

[Jellei]

Well... "is" isn't for plural, isn't it? :) But well, you could say that, I guess.
