Family-run bakers, Bells Food Group, is looking to recruit up to 30 workers as part of the expansion plan.
The Shotts-based bakery is looking to take on a further 20 to 30 staff to add to its 200-strong workforce as part of the three-year investment plan.
Bells is ranked fifth in the top 50 recognised food brands in Scotland, and accounts for a 58% market share of all branded pie sales nationally.
The company has also developed a range of export cakes under the Kirriemuir Gingerbread brand, which sell in North America.
Airdrie & Shotts MP Neil Gray said: “Bells is a huge success story for Shotts, known and respected nationwide. Having discovered the plans for the future, I can only see that success continuing.
“Bells Food Group is a tremendous asset for the area and I will help and support them in any way that I can.”
