According to MINA, the worst offender amongst the new flavours is the Cinnamon Roll, which Starbucks describes as "sweet and spicy".

Starbucks launches coffee that 'tastes like Guinness'
What insights do baristas get from their customers?

It's made up of cinnamon dolce syrup blended with coffee, white chocolate mocha sauce and vanilla bean, topped with whipped cream and a cinnamon dolce sprinkle - so perhaps it's no surprise that it also contains an enormous 102g of sugar (20 teaspoons), the equivalent of drinking a one-litre bottle of Coca Cola.

It's also more than double the recommended daily allowance of sugar for adults in the UK.

Next on the naughty list is the Caramel Cocoa Cluster, with 97.3g (19 teaspoons) of sugar - made up of toffee nut syrup, blended with coffee, topped with a dark caramel sauce, whipped cream and mocha drizzle.

At three, it's the Red Velvet Cake Crème, with 87g (17 teaspoons) of sugar hiding inside its chocolate chips, mocha sauce, raspberry and vanilla syrup, topped with whipped cream. That's the equivalent of two slices of carrot cake.

Then it's the Cotton Candy Crème, which has 83g (16 teaspoons) of the sweet stuff. It's neon pink and is made up of vanilla bean crème, blended with raspberry syrup and, if that wasn't enough, is also topped with whipped cream.

Cupcake Crème is at number five, with 79g of sugar (15 teaspoons), consisting of vanilla bean crème, blended with hazelnut syrup and the obligatory whipped cream.

Has Starbucks sneaked cappuccino off the menu?

Lastly, the Lemon Bar Crème has 71g of sugar (14 teaspoons) making up its lemonade and vanilla flavour, topped with whipped cream and a caramel sugar sprinkle.

If you're in Britain and you're still craving something sweet after reading that, then you might have to book yourself a plane ticket - the drinks, which are being dubbed by the coffee giant as 'fan flavours', and are reportedly inspired by the 'secret' Starbucks menu, are currently only available in the US.
