Sweet served in butter plate (6,7)

I believe the answer is:

peanut brittle

'sweet' is the definition.
(peanut brittle is a kind of sweet)

'served in butter plate' is the wordplay.
'served' is an anagram indicator.
'in'+'butter'+'plate'='inbutterplate'
'inbutterplate' is an anagram of 'PEANUT BRITTLE'.
