United Biscuits is gearing up for Hallowe'en by launching 'spooky' Jaffa Cakes to cash in on the October festival.

McVitie's Jaffa Cakes Lemon & Slime and Jaffa Cakes Spooky Mini Rolls will be available from next month in ghoulish Hallowe'en-inspired packaging featuring pumpkins, spiders' webs and bats, with jokes on the reverse.

Lemon & Slime comes in 150g single packs (rsp: £1.21) and 300g twin-packs (rsp: £2.26). Available in a blend of dark chocolate and light sponge with an orange centre, the individually wrapped rolls come in packs of six (rsp: £1).
