Ingredients:
- 1 sheet of store-bought puff pastry, thawed if frozen
- 1/2 cup granulated sugar
- 1 teaspoon vanilla extract
Instructions:
-
Preheat the oven:
- Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or silicone baking mat.
-
Prepare the puff pastry:
- On a lightly floured surface, roll out the puff pastry sheet into a rectangle, about 1/8 inch thick.
-
Add vanilla sugar:
- In a small bowl, combine the granulated sugar and vanilla extract. Mix well until the vanilla is evenly distributed throughout the sugar.
- Sprinkle half of the vanilla sugar evenly over the rolled-out puff pastry sheet, pressing it lightly into the pastry with your hands or a rolling pin.
-
Fold the pastry:
- Starting from one long edge of the rectangle, tightly roll the pastry toward the center, stopping halfway.
- Repeat the rolling process from the opposite long edge, so both rolls meet in the center.
- Press the two rolls together gently to seal.
-
Slice the cookies:
- Using a sharp knife, slice the rolled pastry crosswise into 1/2-inch thick slices.
-
Coat with sugar:
- Dip each slice into the remaining vanilla sugar, coating both sides generously.
-
Bake the cookies:
- Place the coated palmier cookies on the prepared baking sheet, leaving some space between them to expand.
- Bake in the preheated oven for 10-12 minutes, or until the cookies are golden brown and crispy.
-
Cool and serve:
- Remove the baked palmier cookies from the oven and let them cool on the baking sheet for a few minutes.
- Transfer the cookies to a wire rack to cool completely before serving.
Enjoy these delightful palmier cookies with vanilla as a sweet treat with your favorite hot beverage or as a crunchy snack on their own!
