Tilly Wilkes, Yana Daniëls and Alethea Paul also found the target as the Clarets started Interim Manager Louise Roberts’ reign in style.
The Clarets named an unchanged starting XI for the third league match running, with Wilkes captaining the side.
One change to the bench from last week’s trip to Wolverhampton Wanderers saw Brooke Cairns replace Naomi Hartley.
Burnley had the better of the early running and Wilkes thought she’d opened the scoring in the 16th minute, but the linesman’s offside flag thwarted her celebrations.
Jasmine Matthews worked Lightning ‘keeper Ash Naismith from 35 yards and Millie Ravening fired narrowly wide twice before Wilkes found the back of the net again in the 28th minute.
This time it did count after great work from Charley Docherty, who beat her defender and crossed for her opposite wing-back to finish first time off a post.
Lawley then struck twice in the space of three minutes at the end of the first half to give Burnley full control.
Her first goal was a reactionary finish inside the six-yard box after some slack defending, while her second was a fantastic left-footed finish into the top right corner from 20 yards.
The Clarets were full throttle after the restart and Daniëls netted her first goal for the Club in the 53rd minute.
Walker capitalised on a lapse in concentration from a Loughborough defender and rounded their ‘keeper, before squaring for Daniëls to sweep home.
Roberts turned to her bench for the first time with 68 minutes on the clock, introducing Paul and Abbey-Leigh Stringer for Matthews and Brenna McPartlan.
It took just four minutes for Paul, who scored off the bench in our season opener against Middlesbrough, to do so again here.
The wing-back’s looping effort found the back of the net from 20 yards after Walker had hit the bar moments before.
More changes saw Daniëls and Lawley make way for Millie Chandarana and Charlie Chadwick respectively and Burnley continued to push forwards, with Stringer having a goal-bound effort cleared off the line.
Our final substitution saw Heidi replace Walker and the remaining minutes passed with no action to note, meaning the Clarets have conceded zero goals in their three league matches to date.
A points tally of seven from a possible nine leaves Roberts’ side top of the Northern Premier Division of the Women’s National League on goal difference.
Next up is a home game against Huddersfield Town in the FA Women’s National League Cup on Sunday 7th September.
