The veteran midfielder's match-winning double against Aston Villa saw him surpass Bobby Tambling's club tally, notching his 202nd and 203rd strikes in his 606th appearance.
The 34-year-old scored twice at Villa Park on Saturday to give the Blues a 2-1 win and effectively seal a place in this season's Champions League, as well as overtaking Bobby Tambling’s 43-year-old club record tally.
And Lampard has dedicated his match-winning performance to his mother, who died of pneumonia in 2008, describing her as his "biggest supporter".
"I’ve been here a long time. I lost my mum a few years ago and she was my biggest supporter so it was for her," Lampard told Sky Sports. "Not much beats [the Champions League final win in] Munich as that was amazing for the team and the club but personally it’s another great day, I’m really pleased."
Lampard admitted it felt "amazing" to finally break Tambling’s record, but suggested he could not have achieved the feat were it not for the support he received from supporters and teammates alike.
"It’s amazing [to break the record]," Lampard continued. "I’m thankful to every one of my team-mates because they’re the ones that put it on a plate for me sometimes and the fans - they’ve all been willing me to do it for a long time and probably getting frustrated alongside me not getting there.
"I’m just delighted and the way the fans were at the end there means everything to me. Bobby Tambling is a great man and I was pleased to level but I didn’t want to over-cook that celebration. But to then go and break it I was delighted and I’m just very pleased today."
Chelsea’s win leaves it six points clear of Tottenham with a vastly superior goal difference and Lampard is now looking ahead to Wednesday's Europa League final against Benfica and the Blues’ final-day clash with Everton.
"It’s huge for the team. With the Europa League final coming up we wanted to put it to bed today," he added. "It was a very tough game, we knew that, but [we showed] great character after we went down to 10 men to keep going in the game and get a result.
"It’s a massive game on Wednesday, we need to rest and be ready for that. It will be a very, very tough game and at Chelsea we’re all about winning titles.
"We’ve done it for a long time here now and it looks like we’ve got Champions League now. We want to try and get third place so there are two big games to try and win."
