Moved suddenly like cat — concoction with cream secured (10)

I believe the answer is:

whiplashed

'moved suddenly like cat' is the definition.
(moved like a whip - cat can mean a whip)

'concoction with cream secured' is the wordplay.
'concoction with cream' becomes 'whip' (whip can mean a cream-based dessert).
'secured' becomes 'lashed' (I've seen this in another clue).
'whip'+'lashed'='WHIPLASHED'

I've seen this clue in The Guardian.
