Humble Crumble is a dedicated crumble bakery founded in 2018 by Kim, who won awards for her homemade crumbles before opening the first stall at Maltby Street Market near Tower Bridge. Now operating across multiple London locations including Old Spitalfields Market, the bakery serves fresh crumbles daily with a commitment to sustainability. They use carbon-negative Wildfarmed flour, Madagascar vanilla from Zazou Emporium sourced through farmer-led cooperatives, and dairy from Northiam Farm in Sussex where cows graze in large fields. Every crumble reflects their values around compassionate sourcing and environmental responsibility.
