The Vegan Caramelized Biscuit Cheesecake features a cinnamon spiced biscuit base and crunchy honeycomb topping (which does not contain honey). It joins the chain's orginal plant-based pudding - the Sticky Chocolate and Praline Torte.
The new dessert follows Zizzi's recent major launch - the Quattro No-Maggio - which is the high street's first vegan four cheese pizza, topped with Mozzarisella - in original, smoked, cheddar and blue varieties. The pizza is available on a standard or gluten-free base.
"Over the past year we've seen vegan dishes become more popular than ever and we're anticipating that this January will be the biggest Veganuary yet," Kathryn Turner, Director of Food Development at Zizzi, said in a statement sent to Plant Based News.
"Our vegan customers tell us it's important that they have a wide choice and are not just 'stuck' with one option from the menu.
"We hope they'll love our first four vegan cheese pizza and hope it will help first-time vegans get their cheese fix this month. We can't wait to hear what our customers think."
The Quattro No-Maggio is available nationwide from January 8 and in selected restaurants from January 2. It is part of Zizzi's special two-for-one offer on all vegan mains throughout the month.
