On 13 December 2019, the Hoyle couple released a single entitled "I Love Sausage Rolls", a parody cover of Alan Merrill's "I Love Rock 'n' Roll". Nick Southwood co-wrote the new lyrics with the Hoyles, produced, mixed and performed bass and lead guitar. The single's cover is based on Abbey Road's cover. The song became the Christmas number one, beating the likes of Stormzy (#2), Lewis Capaldi (#3) and Dua Lipa (#4), and spent one week in the top 40. The couple are the third act to have two consecutive Christmas number one singles and the first to have two successive novelty Christmas number ones in the UK.

In June 2018, following an online public vote, Mark Hoyle won Clas Ohlson's 2018 "Celebrity Dad of the Year" award, beating Prince William and others. Nine months later, Roxanne Hoyle won Clas Ohlson's 2019 "Celebrity Mum of the Year" award, beating out Holly Willoughby and Catherine, Duchess of Cambridge, among others. In November, the Hoyle couple published a book titled Parenting for £1: …And Other Baby Budget Hacks, in which they wrote about their life hacks.

On 14 December 2018, the Hoyle couple released their charity single, a parody cover of Starship's 1985 single "We Built This City". The amended lyrics had a sausage roll theme with the refrain being changed to "We Built This City on Sausage Rolls". All profits from the charity single went to The Trussell Trust. The song debuted at number one on the UK Singles Chart, beating Ava Max's "Sweet but Psycho" and Ariana Grande's "Thank U, Next" to the 2018 Christmas number one, making the Hoyles the first British YouTubers to top the chart. It also topped the Scottish Singles Chart and appeared in Australia's ARIA Digital Track Chart and the US Hot Rock Songs chart peaking at #31 and #47 respectively.

Mark Hoyle has been married to Roxanne Hoyle (née  Messenger) since May 2015, and they have two sons, Phoenix Forest and Kobe Notts, born in 2016 and 2018, respectively. While Roxanne was pregnant with their first son, Mark created a blog named "LadBaby" (reflecting the fact that he "was a lad and [he] was having a baby"), in which he documented his day-to-day life as a first-time parent. As of December 2019, the LadBaby YouTube channel, Facebook page and Instagram account have over 744,000 subscribers, 3,865,000 likes and 779,000 followers respectively. LadBaby's video content, uploaded onto their Facebook and YouTube accounts, consists mainly of vlogs in which Mark demonstrates life hacks which help him to save money when faced with potentially costly parenting tasks. In June 2017, one vlog, in which he bought a toolbox from a hardware store to serve as a lunchbox for his son, went viral. Other creations by him include a baby walker made of pipes, a makeshift paddling pool made from a skip and a makeshift baby gate made from half of a door. Other viral videos include two uploaded in February 2018, when the Hoyle couple had each other's cars wrapped with love heart stickers and photographs of their faces. LadBaby is also known for the catchphrase "Yes, mate!", which is often said in the videos. In October 2018, the Hoyles launched a spin-off YouTube channel, LadBaby & Sons, in which their sons take a more active role. The channel generally focuses on toy testing and kid-friendly social media challenges.

In 2012, the couple took part in Channel 4’s Hidden Talent. Trained by former champion freediver Emma Farrell, Roxanne Hoyle was able to hold her breath underwater for four minutes and eighteen seconds.
