A clear breakdown of which UK regulated allergens are in (or might be in) every item we serve. If you have a severe allergy, please talk to a team member at the kiosk — we'd rather be careful than sorry.
What's in our poffertjesEvery Stacked starts with the same fresh poffertjes batter, which contains wheat & gluten, milk, eggs, sugar, hazelnuts and soya, and may contain traces of nuts. Each topping, fruit and extra you add brings its own ingredients — the table below shows the regulated allergens in each.
ImportantOur kiosks handle nuts, dairy, gluten, soya and eggs. We do our best to prevent cross-contamination but we cannot guarantee a fully allergen-free product. If you have a severe allergy, please speak to a team member at the counter before you order — we'll walk you through every ingredient on the day.
