Ready for next level cream puffs? Craquelin is a crunchy dough that’s rolled, frozen, cut into circles and placed on top of the puffs before baking. In the oven it melts down over the sides and creates an irresistibly crunchy bun! You can use this recipe as a starting point and add a tablespoon of matcha, cocoa, expresso powder, or freeze dried raspberry powder for flavoured craquelin.
