These cool whoopie pies are a retro treat for adults and children alike, perfect for a barbecue or summer party

Hannah Miles: "These pies are a classic chocolate whoopie, just a little bit chillier, and perfect for a barbecue party on a summer’s day. You’ll need to assemble them at the last minute so that the ice cream doesn’t melt. I’ve used vanilla here but you can substitute any flavour you like – why not try chocolate for a double chocolate treat!"
