Palmiers or elephant ears are crunchy and crispy French biscuits that require two ingredients only, and one of them can be bought ready made from the store.
Cut the puff pastry block into 2 parts so that it’s easier to roll. Spread a large sheet of baking paper on the work surface. This will help in preventing the dough from sticking to the work surface, and also help in moving it.
Line a baking sheet with parchment/baking paper, and place the cookies on the sheet. Sprinkle the palmiers with more sugar, if you want. Make sure to leave space between the palmiers as they will puff up.
Bake the palmiers, turning them halfway through, until crisp and golden, with the sugar turning into caramel during the baking process. For the puff pastry I use, the baking process takes about 30 – 40 minutes but this would be less if using foreign puff pastry sheets.
