Morgan Rogers’ opener for Villa on the stroke of half-time was equalised by a Virgil van Dijk header early in the second period.
But finishes from Ollie Watkins in minutes 57 and 73 established a two-goal cushion for the hosts.
The scoring was completed in the closing stages with a John McGinn curler and Van Dijk consolation.
