LIFE doesn’t get much sweeter than biting into a warm honey cake, fresh from the oven.

But in this kitchen, there’s no refined sugar - nor gluten or dairy, for that matter - in sight. This is Livia’s - aka Olivia Wollenberg’s - kitchen, and she’s made her name by baking with more gut-friendly alternatives to the white stuff.

Wollenberg started off baking and selling hundreds of fresh crumbles from her mum’s kitchen in North London, and now has a range of Raw Millionaire Bites - her gluten, dairy and refined sugar-free answer to millionaire’s shortbread, filled with gooey date caramel - which are a bestseller in Selfridges’ Food Hall.

Her honey loaf cake, which today she’s shown me how to bake into mini muffins to share, uses raw honey, coconut palm sugar and ground almonds instead of flour, with coconut oil standing in for butter - ingredients which don’t make her feel ill when she fancies a treat.

Like her friend Ella Woodward of Deliciously Ella fame (Wollenberg made the 14-layer cake at Woodward’s Mustique wedding in April), it was her own health problems that eventually inspired Wollenberg to revolutionise her approach to eating - and then turn it into a business idea.

“I was always the person at three o’clock who would be like, ‘I need some chocolate, I need a cupcake’. I think a lot of people feel that - a working day is really long. Even at school, I was excited for my mum to pick me up because I knew she would come with Nutella sandwiches in the car,” confesses the 27-year-old, whose naturally sweet recipes are featured in her debut cookbook, Livia’s Kitchen.

“I was always just living for food. But my stomach got more and more sensitive. I would go out for dinner with my friends on a Saturday night and never be able to join them at a bar afterwards because I was in so much pain. I didn’t want to go and see a doctor because I still wanted to go for pizza, and I was so scared they would say to me, ‘You can’t eat gluten and dairy any more’, so I just put up with it.”

In spring 2014, things were so bad that her mum, who she was still living with at the time, told her enough was enough. “She said, ‘You’re not nourishing your body because what you’re eating is just not staying in’,” recalls Wollenberg.

She finally saw a nutritionist, who made her keep a food diary for two weeks.

“She looked at the first two pages and said, ‘Just what I thought, you’re someone who’s going to need to follow a FODMAP diet’. And I was like, ‘A FODMAP what?’”

FODMAPs are short-chain carbohydrates that can be poorly absorbed in the small intestine, resulting in IBS-like symptoms for some. Reactions can, of course, vary in severity. Among the worst offenders are onions and garlic, which Wollenberg now avoids entirely - “even a trace can make me really sick”.

For six weeks, she had to cut out a whole list of possible trigger foods, including apples, with the idea she’d then be able to gradually reintroduce them again.

“Most people can reintroduce 90% of foods and have one or two they cut out. I pretty much couldn’t reintroduce anything, except apples.”

Although she now says the restricted diet “ruined my life”, it also set her on a path to swapping academia (she’d been studying neuroscience at UCL) for entrepreneurship.

“The thing I was most miserable about was having something indulgent and delicious without any gluten, dairy and refined sugar. So I started looking at blogs online and people were talking about using natural sugars, like dates, maple syrup, coconut sugar, and them reacting better with their body. I just started playing around because I needed a three o’clock pick-me-up. At the time it wasn’t a business idea, it was just to keep me going because I was so miserable.”
