Warm worker's sweets (8)

I believe the answer is:

fondants

'sweets' is the definition.
(fondant is a kind of sweet)

'warm worker's' is the wordplay.
'warm' becomes 'fond' (synonyms).
'worker's' becomes 'ant's' (worker is a type of ant).
'fond'+'ants'='FONDANTS'

(Another definition for fondants that I've seen is " Sweets made of sugar and water paste".)

I've seen this clue in The Guardian.
