What is olivers favorite type of sweets?

Please provide me with more context! Who is Oliver? Without knowing who Oliver is, I can't tell you his favorite sweets.

For example, you could say:

* "Oliver is a 10-year-old boy. What are his favorite types of sweets?"

* "Oliver is my friend who loves chocolate. What are some of his favorite chocolate sweets?"

The more information you give me, the better I can answer your question. 😊
