Baking appliance (4)
I believe the answer is:
oven
'baking appliance' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for oven that I've seen before include "Kitchen range, say" , "Cooking appliance" , "Metal box in which to roast" , "kitchen item" , "Enclosed chamber for cooking" .)
