Waffle baking attracts publicity (3,3)

Ross

I believe the answer is:

hot air

I'm a little stuck... Click here to teach me more about this clue!

'waffle' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'baking attracts publicity' is the wordplay.
'baking' becomes 'hot' (similar in meaning).
'attracts' is a charade indicator (letters next to each other).
'publicity' becomes 'air' (I've seen this in other clues).
'hot'+'air'='HOT-AIR'

Can you help me to learn more?

(Other definitions for hot air that I've seen before include "Empty or boastful talk - good for balloons" , "Boastful talk or balloon filling" , "Gas" , "Bombastic talk or balloon elevator" , "Loud and empty talk to lift a balloon?" .)
