ID a children's book

I have vague memories of a book I used to have as a child: all I remember about it is a rabbit going around and collecting ingredients from other forest animals to make a bread pudding.

Does this ring any bells?

Naked Lunch?

Is there a bear involved?

Do you remember if it was it a regular-sized book, or one of those pocket-sized board books? Because that plot summary sounds very familiar to me, and it’s making me think of a board book that I had as a child.

I don’t really know. Maybe. I remember it involving a lot of small forest mammals. They all eat the bread pudding together at a party at the rabbit’s house inside a tree at the end (I think; maybe I’m making up the tree part, but I think I remember the rabbit living inside a tree).

All Google is giving me are recipes for bread pudding.

Again, sorry, I don’t remember. Maybe.

There’s always a bear.
