In a series of videos, Stefani, 47, and Shelton, 40, can be seen making homemade gnocchi.
The duo also adventured around Shelton's native Oklahoma, where Stefani documented their wild turkey sightings, a beautiful sunset and Christmas lights.
At the end of one of the videos, Stefani even showed off an adorable cartoon-like version of her and the "She's Got a Way With Words" singer standing next to a snowman, created on the popular Bitmoji app.
The No Doubt frontwoman also recently changed her Twitter profile pic to a festive photo of her beau all wrapped up in red-and-green lights.
The lovebirds appear to be just as happy as they were one year ago, when they were spotted spending the holidays with Shelton's family in Oklahoma. A few days later, photographers captured the two snapping selfies on their date to the Arizona Cardinals v. Green Bay Packers game at the University of Phoenix Stadium in Glendale, Arizona.
Relive their sweet moments together in the video below!
