A West Yorkshire-based confectionery business has secured £70,000 from NPIF II – BEF Smaller Loans, which is managed by Business Enterprise Fund (BEF) as part of the Northern Powerhouse Investment Fund II (NPIF II).
The funding also came from BEF’s Community Investment Enterprise Fund 2 (CIEF2) backed by Lloyds Bank and Better Society Capital. This funding will play a crucial role in expanding the company’s operations and enhancing its commitment to crafting innovative, gourmet marshmallows.
The investment will establish a new bakery facility, significantly boosting production capacity to meet the demands of the new contract. This expansion will create five new jobs and secure seven existing positions at the Leeds site, driving local economic growth.
Founded by renowned chocolatier Oonagh Simms in 2011, The Marshmallowist pioneered the UK’s gourmet marshmallow market. Combining traditional confectionery techniques with bold flavours, the brand uses premium ingredients like fresh fruits, organic herbs, fair-trade sugar, and boutique alcohols. All products are egg-free, dairy-free, and gluten-free, catering to diverse dietary preferences.
Oonagh's journey began at 18 when she moved to Paris to train as a pâtissier and chocolatier. Four years later, she returned to the UK to launch The Marshmallowist from a stall at Portobello Road Market, reinventing the classic treat with a gourmet twist. In 2014, her sister Jenny joined as a director, bringing expertise in brand development and strategy. Together, they transformed The Marshmallowist, blending culinary artistry with savvy business tactics, and securing its place in luxury retailers like Selfridges and Harvey Nichols.
After securing a key contract with a growing chocolate brand, the sisters set their sights on upgrading their production facility at Springfield Mills in Farsley, Leeds. They were introduced to BEF by David Baggaley, a Business Advisor at Leeds City Council, who played a crucial role in securing the funding and grants for their expansion.
Oonagh Simms, chocolatier and director at The Marshmallowist said:
This investment marks a significant milestone for us. With the new bakery facility, we can expand our production to meet the growing demand and continue pushing the boundaries of what a gourmet marshmallow can be. We're thrilled to take this next step in our journey and bring more of our innovative flavours to our customers. It's not just about growth; it's about keeping our passion for quality and creativity at the heart of everything we do.
Doug Heseltine, Senior Investment Manager at BEF said:
The Marshmallowist is a fantastic example of a business that combines creativity with a clear growth strategy. We're proud to support Oonagh and Jenny as they expand their operations and take on exciting new opportunities. This investment not only helps scale their production but also contributes to job creation and economic growth in the region, which aligns perfectly with our mission and the goals of the Northern Powerhouse Investment Fund II.
