Sales reached £9.5m last year at the 25-year-old family-owned firm, which now plans to increase manufacturing capabilities and plant capacity over the next 18 months. It has already spent £2m on a new production line, which helped to develop the new Gourmet Goodness range, as part of an ongoing growth strategy.
Sales director Ewan Anderson said: "The launch of the new range follows an investment in the capacity and capability of the plant, a new production line, an advertising campaign on STV and an extensive redesign of the packaging and website.
"There is a real opportunity in the premium biscuit category and we're looking to expand the business throughout the UK and abroad by continuing to produce the best quality biscuits that we can possibly bake."
The Gourmet Goodness range includes fruit, seeds and nuts, combined with slow baked oats. Six varieties include Pecan & Maple Syrup Granola Cookies, Blackberry & Apple Crumbles, Tropical Fruit Crumbles, Red Berry Rascals, Yogurt Cranberry & Pumpkin Seed Crumbles, and Raspberry White Chocolate & Pistachio Crumbles.
