Premier is bringing back its Mr Kipling Fiendish Fancies, Cadbury Trick or Treat Mini Rolls and Cadbury Cake Bars in Cinder Toffee and Scary Orange variants (rsp: £1) with new, more gruesome packaging.

Mr Kipling Devil Slices a variation of the existing Angel Slices line will also be part of next month's launch.
