The actress, 41, who welcomed son Malcolm Hiệp Mulaney on Nov. 24, jokingly put the couple’s tyke in a bun steamer while cooking with the “Saturday Night Live” writer, 39.
“Lol, daddy’s new báhn bao recipe,” Munn captioned a pic of her Mini-Me, along with a dancing dumpling emoji.
She added a second snap to her IG story, declaring little Malcolm totally “adora-bao.”
It seems the couple was helping Munn’s mother prepare the traditional Vietnamese dish in time for New Year’s Eve.
“Mom’s practicing her báhn bao for New Year’s dinner and wanted to show it off,” the “Office Christmas Party” star added in another story.
Munn’s holiday posts come just a few days after the couple shared the first photos of their sweet baby boy.
“My Golden Ox baby. Malcolm Hiệp Mulaney. Happy Holidays,” Munn wrote via Instagram on Dec. 23, alongside a pic showing the infant snoozing in a fluffy blanket.
Prior to Malcolm’s arrival, the actress admitted that she and the stand-up comedian, who started dating earlier this year amid his divorce from Anna Marie Tendler, were “scared” to become first-time parents.
“We talk about the same stuff. Which rocker? What type of crib do you put the baby in? What does the baby wear?” she said on the “Today” show in November.
“Honestly, thank God for Instagram and Facebook and blogs because there’s a lot of moms who put out such great information, and that’s been a saving grace for me.”
Mulaney first confirmed he and Munn were expecting a child together during an appearance on “Late Night with Seth Meyers.”
“I got into this relationship that’s been really beautiful with someone incredible,” he said at the time. “And we’re having a baby together. I was nervous when I was about to say the news!”
