I believe the answer is:

bake

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

'cook' is the definition.
(baking is a kind of cooking)

I can't explain the remainder of the clue.

(Other definitions for bake that I've seen before include "Cook cake or bread" , "Cook (eg, bread)" , "Cook (cakes, etc)" , "Cook by dry heat in an oven" , "Cook (eg, cakes)" .)

I've seen this clue in the Sydney Morning Herald.
