The dairy-free desserts, which are made primarily from coconut milk, include a chocolate mousse with chocolate ganache, sauce, and 'nibs', and a coconut pannacotta topped with mango and passionfruit compote.
'You asked and we delivered'
Marks & Spencer announced the launch of the desserts on Facebook, in a video that described the treats as 'delicious' and 'yummy' - captioned: "You asked and we delivered: we're making M&S Plant Kitchen even sweeter with our £1.75 vegan dessert pots."
Mini versions of the desserts are also available to order online, priced at £7 for six small pots.
The Plant Kitchen range was introduced last year, welcoming 60 plant-based products to its stores. Since then, the retailer has added more vegan offerings, saying the products are 'flying off the shelves'.
'It's experimental, and it's delicious'
Claire Richardson, who developed the range alongside a team of food experts, said in a statement: "Some people think meat-free food is boring but that couldn't be further from the truth, it's experimental – and it's delicious.
"We've created a collection that will appeal to everyone – whether you're a longstanding vegan, want to lead a more flexitarian lifestyle or you love meat but think cauliflower popcorn sounds amazing. It's all about delicious tasting food first - and plant-based second."
