Everything caretaker boss Mike Jackson touch was turning to gold but his was one game in which the wheels well and truly fell off.
It is a result that will leave relegation rivals Everton and Leeds United frothing at the mouth while ramping up the pressure on his own squad of players.
Story of the match
Burnley made one change from their victory against Watford. Ashley Barnes came in for the injured Matej Vydra.
And two of the visiting fresh faces combined for the early opener.
Bunedia had too much time in the centre of the pitch and he threaded Ings through on goal. The striker took his time before slotting the ball past the helpless Nick Pope, continuing his trend of scoring in every match against his former club.
It was another slow start from the Clarets, who did seek an immediate reply through Barnes, but the 32-year-old couldn't keep his strike from distance down.
Wout Weghorst had two half-chances opportunities to claw Burnley back into the contest: bending a 25th-minute first-time effort wide from inside the box before flicking a header past the post after latching onto a good across from Dwight McNeil.
But it was the Villains, who always looked a threat on the break, who doubled their lead.
An overlapping Lucas Digne stormed onto Oli Watkins' pass before drilling the ball across to an unmarked Buendia. The Argentine's shot took a slight deflection and wrong-footed Pope.
But Villa were almost the founders of their own downfall in the 42nd-minute when Tyrone Mings' stumble allowed McNeil a clear run into the box. The winger demonstrated why he hasn't scored a goal this season, though, with a tame effort into the gloves of Emi Martinez.
It was a big second-half for the hosts and things quickly went from bad to worse as James Tarkowski almost immediately has to leave the field with an innocuous looking injury; Kevin Long was the one to dust himself down and slot in alongside Nathan Collins.
And the wheels invariably came off shortly after that.
On 52 minutes, Burnley came out on the wrong end of several second-balls and Watkins powered a close-range header through the legs of Pope following a pinpoint John McGinn cross.
Turf Moor were stunned into silence as their survival dream began to take a battering.
Moments later, Matty Cash turned Charlie Taylor inside-out and forced Pope into an excellent save at his near post.
The game fizzled out from that moment on. Pope made some simple saves to keep out Watkins and McGinn.
However, Cornet did get himself a goal after coming off the bench.
The Ivorian raced onto a through ball from fellow substitute Erik Pieters before rounding Martinez and smashing the ball home in the dying embers.
It was an impressive performance form Gerrard's men – racking up back-to-back wins and clean sheets.
Burnley are almost back to where they were before Jackson: with it all to do. Their recent form has been mesmeric but nobody near the bottom – with the exception of Watford and Norwich City – wants to fold.
But perhaps Burnley are at their best when everybody starts to write them off? Jackson will hope so. Next week really doesn't get any bigger and one of those season defining games is, of course, at Villa Park!
