What is this anime?

[warrof 11]

My Japanese teacher had us watch an anime in class, and I want to know what its name is (she borrowed it from a student so she doesn't know what it is called).

 

This is what I remember about it.

1. Childish everything.

2. All characters had cats ears and tail.

3. All characters ended their sentences with "nya."

4. Main character was a kid princess.

5. First or second episode, the main character and her friend go to a , apperantly, famous cake shop.

 

I'll add any other things I remember about it.

 

Please if you know what it is called please tell me!!!!
