With only 3 ingredients and 5 minute prep time, craquelin is a common patisserie secret of adding a crunchy cookie topping to choux pastry cream puffs!
Add softened butter and mix until flight and fluffy.
Add brown sugar and flour and cream together until combined. It will ball in the middle of bowl.
Place the mix onto a large piece of parchment that has been sprinkled with flour.
Roll until about ¼ inch thick
Place in the freezer for at least 30 minutes
Once you're ready to cook your cream puffs, use the circle cookie cutter to cut circles and place them on top of the pate a choux. If too hard to cut, let defrost for a minute or two.
Cook pate a choux as normally instructed.
Violla! Cream puffs with a crunchy cookie top.
Notes
The size of the cookie cutter circle will determine how much of the cream puff is covered with topping. The bigger the craquelin circle the more the cream puff that will be covered in craquelin. If you want just the top of the cream puff covered, use a smaller cookie cutter. If you want the whole cream puff covered with craquelin, make sure the craquelin disk is about as big as the piped cream puff itself.
Make sure roll the dough to about ¼ in thick and freeze it for at least 30 minutes.
Rolling the dough out on parchment or wax paper allows you to easily transfer the rolled dough to a pan to place in the freezer.
The dough softens pretty quickly so if the dough gets too soft while cutting the circles, put it back in the freezer for 5-10 minutes to firm up.
If making ahead of time, wrap tightly in plastic wrap and aluminum foil to keep from taking on any flavors from the freezer or fridge.
