Cake Alice produced: last piece for Hatter? (6)
I believe the answer is:
eclair
'cake' is the definition.
(I've seen this before)
'alice produced last piece for hatter?' is the wordplay.
I cannot really understand how this works, but
an anagram of 'alice' is 'eclai' which is present in the answer.
'piece' could be 'r' (abbreviation for Rook) and 'r' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for eclair that I've seen before include "Chocolate-topped, cream-filled cake" , "Bakery item" , "Finger-shaped cake with cream filling" , "Choux pastry cream cake" , "Lacier type of cake" .)
