'tart' is the definition.
Both the definition and answer are adjectives.
Perhaps there's an association between them I don't understand?

'british duke pedalling furiously gobbling wife's' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'furiously' indicates anagramming the letters.
'gobbling' indicates putting letters inside.
'wife' becomes 'w'.
'b'+'duke'+'pedalling'='bdukepedalling'
'bdukepedalling' with letters rearranged gives 'bakeellpudding'.
'bakeellpudding' enclosing 'w' is 'BAKEWELL PUDDING'.
