ABANDONED. Children's find it book that takes place in a huge, chaotic mansion

[La]

I'm looking for the name of a find it book (sort of like Where's Waldo) that I loved when I was young. It took place in a mansion, and each spread was a room within it. There were always crazy things happening in the rooms, and the objective was to find specific things (listed somewhere on the page) within the room and all its chaos. Some more things I remember:

- I believe the "protagonist(s)" of the book was a boy and a girl who was visiting a rich family member at their house
- In the kitchen part of the room, one of the things on the list to find were jars of molasses (oddly specific, I know, but just something that stuck!)
- The first spread was the mansion from outside during the day, and the last spread was the mansion from outside at night
- The last room was the bedroom, where lots of people were having a pillow fight
- The garden had a bush maze

I hope someone can help me with this, and I appreciate any responses!

Mystery Mansion by Michael Garland?

La, around what year did you read this book?
Are the illustrations cartoon-like, realistic, bright and colorful, etc.?
