In her first talk-show visit since announcing her candidacy, Hillary Clinton largely stayed away from heavy topics, though she did touch on a couple of serious subjects.

Appearing on The Ellen DeGeneres Show, which taped earlier in the week and aired Thursday, the Democratic presidential front-runner addressed questions of whether, at  67, she might be too old to serve as president.

“I would be the youngest woman ever elected,’’ said Clinton, echoing a line she used during her campaign kickoff event in June.

She also repeated an apology she first issued earlier this week over  her use of a private email server as secretary of State. She also said she was disappointed that Republican candidates didn’t offer more concrete policy ideas during their first debate.

On a lighter note, Clinton talked about everything from her love of Tabasco sauce to what she wants her granddaughter, Charlotte, to call her: “I’m fine with Grandma, I’m fine with Madam President.’’

A 5-year-old guest host named Macey Hensley, who’d memorized a series of presidential factoids, asked Clinton if it’s true that she hasn’t driven a car in 20 years.

“It’s not quite that long but pretty close,’’ Clinton said, citing Secret Service protection guidelines. “But I used to love to drive a car.’’

Other highlights include:

• Clinton performing the Whip/Nae Nae, a dance from DJ Stephen “Twitch’’ Boss.
• Comedienne Amy Schumer gliding across the stage in a blue body suit and red skates. When DeGeneres refused to join her, she asked Clinton instead. “I love her. I love the fact that she’s going after gun violence,’’ said Clinton.
• To cap the show, Macey returned to the stage dressed in a blue pant-suit to the customary Hail to the Chief music played when a U.S. president is introduced blaring in the background.
