The Republic of Ireland international scored what turned out to be the winning spot-kick after a goalless final against Sunday's opponents Chelsea in an epic shoot-out which finished 11-10 when Kelleher's opposite number Kepa Arrizabalaga blazed over, the only failure from either side.
It was fitting for the Irishman, who has been Liverpool's League Cup goalkeeper for the last few seasons, but he would prefer a quieter afternoon this time around.
"To be fair, I was just in the moment. I didn't even realise it was my go and I looked at the lads and they were pointing at me," said Kelleher.
"I didn't have much to think so I just ended up smashing it in."
Asked whether he had practised his penalties again he added: "I've done bits and bobs but I'm hoping we win it in the 90 minutes. I think it's easier for the fans.
"I have great memories from the cup. I think the clear thing will be the penalty, that is a really nice moment.
"Then after Chelsea missed their penalty, our celebration with the fans and the team was a special moment and one I'll never forget and hopefully we can recreate something similar on Sunday.
"It was a good experience to look back on but I'm just trying to focus on getting good results."
Kelleher is set for his longest run in the team as first-choice goalkeeper Alisson Becker, who has already missed the last three matches with a hamstring injury, is sidelined until after next month's international break.
As back-up the 25-year-old has never played more than three consecutive games for the club but, after a similar run in November and December when Alisson was injured, he now has a chance to play a big part in the quest for silverware as the club continue to fight on four fronts.
"It can only help having a run of games as it gets you in a good rhythm and it fills me with confidence playing week in, week out," he added.
"It's good for me as I can get that rhythm and that relationship with the team. It can only help."
Alisson is one of a significant number of absences, which includes Trent Alexander-Arnold, Diogo Jota and Curtis Jones, with Mohamed Salah, Darwin Nunez and Dominik Szoboszlai facing late fitness tests.
Liverpool's midweek win over Luton showed how much their resources were stretched, with three defenders and five academy players on the bench, but assistant manager Pep Lijnders said there would be no excuses made.
"I think the good thing we always did in the past is look at what we have," he said.
"It's also good in life to just accept what you have and don't look (at) what you don't have, so that's what we are trying to do.
"It brought us success in the past, so we try to keep that up.
"This season is a season where we created already three or four new teams in one season - that didn't happen a lot in the last years.
"It's a compliment for our squad, it's a compliment for the academy."
