Colin the Caterpillar cake has been a staple at British birthday parties since it was first introduced by M&S three decades ago in 1990 - and now it comes in jar form too.

Ideal for when you feel like treating yourself to a smaller portion of Colin for dessert, the new Colin the Caterpillar cake jar landed in M&S stores this week alongside two other “cake-away” flavours: the fruity raspberry ripple and caramel-based trillionaire’s.

The Colin cake features layers of rich chocolate sponge, Belgian chocolate sauce, chocolate ganache, milk and while chocolate chips and there’s a mini white chocolate Colin face on top too.

Raspberry ripple has layers of madeira sponge, vanilla buttercream, raspberry jam and freeze dried raspberry pieces while the trillionare’s cake jar also has madeira sponge, salted caramel sauce, chocolate ganache, chocolate shortcake balls and fudge pieces.

“These cake jars are absolutely delicious and are perfect for picnics, lunches on the go – or pretty much whenever you need a sweet fix,” Natalie Tate, lead product developer for M&S Cakes said in a statement.

“Gone are the days of picking a cake to suit all tastes – you can now mix and match to suit everyone. Much like an indulgent ice cream tub – there is something about diving straight in with a spoon that makes the experience all the more delicious."


As well as being announced by the retail giant on Twitter, Instagram account @newfoodsuk was one of the first to pick up the jars and its posts has seen over 16,000 ‘likes’.
