Bakery centrally getting behind beginning to create a bakery product (4)
I believe the answer is:
cake
'bakery product' is the definition.
(bakers make cakes)
'bakery centrally getting behind beginning to create a' is the wordplay.
'centrally' indicates the central letters.
'getting behind' is a charade indicator (letters next to each other) (some letters go behind others).
'beginning to' indicates taking the first letters.
The middle letters of 'bakery' are 'ke'.
The first letter of 'create' is 'c'.
'c'+'a'='ca'
'ke' put after 'ca' is 'CAKE'.
(Other definitions for cake that I've seen before include "Eg, Battenberg, Genoa" , "Something cooked" , "Marie Antoinette's solution to 8" , "Dundee, Madeira, Christmas or birthday?" , "You can't eat it and have it" .)
