General Mills is unveiling a flavour extension to its Cocoa Puffs Combos.

This is the first flavour extension since the brand launched chocolate version in 1958 and will include vanilla and chocolate.

"Kids love to mix together chocolate and vanilla, two of their favourite flavours," said Scott Dorman, associate marketing manager, General Mills. "Cocoa Puffs Combos gives kids the perfect combination of flavours they want."

The new Cocoa Puffs Combos will be available throughout the US.

Last week, General Mills announced plans to extend its offering of Yoplait Light yoghurts in the US with the addition of Strawberry Shortcake, Raspberry Cheesecake and Pineapple Upside-Down Cake varieties to the range.
