'french cakes' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'prepared then mixed in eels' is the wordplay.
'prepared' becomes 'made' ('make' can be a synonym of 'prepare'**).
'then' says to put letters next to each other.
'mixed' indicates anagramming the letters.
'in'+'eels'='ineels'
'ineels' with letters rearranged gives 'leines'.
'made'+'leines'='MADELEINES'
