Halloween is big business, especially when it comes to spooky-season party foods.
The 2026 Mars Tricks, Treats and Trends report found that 57% of US adults no longer view Halloween as one day, but as a full season, while two-thirds of Americans wish they could purchase their favorite Halloween candy year-round, with that number climbing to 76% among Gen Z.
In the UK, meanwhile, overall Halloween spending is forecast to reach £705m this year, up 6% on 2025, with the event falling on a Saturday and shoppers planning parties, fancy dress and decorated homes.
To mark All Hallows’ Eve, Food Formulator has rounded-up its pick of the creepiest and kookiest limited editions launched in 2026, with standout trends including chewy sour candy and chilli spiked foods and drinks.
