How do you diagram this sentence, with a sentence tree?
He loved the sound of pancake batter hissing on the griddle.
See the other post for help with diagramming.
I don't understand the term "tree" but it might have something to do with "hissing..." being a participial phrase.

He loved sound .... is your basic sentence. He = subject; loved = verb; sound = direct object.
of pancake batter = (prepositional phrase) branch off of sound
hissing on the griddle = ( participial phrase) branch off of batter.
