What appliance is used to cook croissant dough into a croffle?

A waffle iron is used to cook croissant dough into a croffle. The appliance presses the dough between patterned heated plates, producing the pastry’s crisp ridges and grid-like appearance while the laminated interior remains buttery and layered.

The name croffle combines “croissant” and “waffle.” Preparation commonly involves using raw croissant dough, rolling or shaping it, coating it with sugar, and placing it in a preheated waffle iron until golden and cooked through. The sugar helps create a caramelized exterior, while the waffle pattern catches toppings such as syrup, fruit, chocolate spread, or ice cream.

The croffle is often associated with South Korea, where it became especially popular in cafés and on social media. However, Irish pastry chef and television personality Louise Lennox is sometimes credited with creating or popularizing the idea at a 2017 Dublin pop-up. An earlier 2015 Food & Wine video also demonstrated the preparation, so the invention story is not completely singular.
