This elegant French pastry requires just 3 ingredients but creates the most stunning flaky, caramelized cookies that look like you spent hours in a professional bakery. The magic happens when the puff pastry is folded into its signature heart shape and the cinnamon sugar creates pockets of sweet crunch throughout.
I first made these palmiers for a last minute dinner party and my guests couldn't believe they weren't from a French patisserie. Now they're my signature treat whenever I need something quick but want to look like I spent hours in the kitchen.
Essentials Ingredients
- Puff pastry: ensuring you use all butter puff pastry for the best flavor and texture as it creates those signature flaky layers
- Granulated sugar: regular white sugar works best as it caramelizes perfectly with a satisfying crunch
- Ground cinnamon: adds warmth and subtle spice that complements the buttery pastry; look for fresh cinnamon with strong aroma
Step-by-Step Instructions
- Prepare the cinnamon sugar:
- Mix the cinnamon and sugar together in a small bowl until completely combined. The cinnamon should be evenly distributed throughout the sugar with no clumps visible.
- Sugar the first side:
- Sprinkle exactly 2 tablespoons of your cinnamon sugar mixture evenly across the surface of the thawed puff pastry. Make sure to spread it all the way to the edges for consistent flavor. Use a rolling pin with gentle pressure to press the sugar crystals into the soft dough which helps them adhere during baking.
- Flip and repeat:
- Carefully turn the pastry over and repeat the same process on the second side. This ensures both sides have that delicious cinnamon flavor and creates the perfect caramelized exterior.
- Create the first folds:
- Starting with the long edges of your pastry square fold each side inward until they reach halfway to the center. Use your rolling pin again to gently press these folds flat which helps maintain the shape during subsequent folding.
- Complete the center folds:
- Take both edges and fold them again so they meet exactly in the center creating four layers of dough. Sprinkle half of the remaining cinnamon sugar over these new folds and roll gently to secure.
- Final fold and chill:
- Fold the dough in half along the center line like closing a book creating six total layers of pastry. Place the folded log in the refrigerator for a full 15 minutes to firm up the butter in the pastry which is essential for clean cuts and proper rising.
- Slice and sugar:
- Cut the chilled pastry log into precisely 1cm thick slices using a sharp knife. Dip each cut edge into your remaining cinnamon sugar mixture ensuring both exposed sides are well coated.
- Bake to perfection:
- Arrange the slices on a parchment lined baking sheet leaving at least 2 inches between each one as they will expand significantly. Bake at 400°F for exactly 14 minutes until the sugar has caramelized to a rich amber color.
- Flip and finish:
- With a thin spatula carefully flip each palmier and return to the oven for just 4 more minutes until both sides are golden brown and perfectly caramelized.
- Cool properly:
- Transfer the hot palmiers to a cooling rack lined with parchment paper to prevent the caramelized sugar from sticking as it cools.

My favorite part of making palmiers is the magical transformation that happens in the oven. My grandmother taught me this recipe and always said the sound of biting into a perfectly crisp palmier was like listening to autumn leaves crunching underfoot. That first bite with the sweet caramelization and delicate layers always takes me back to her kitchen.
The History Behind Palmiers
Palmiers originated in France where they're often called "palm hearts" or "elephant ears" due to their distinctive shape. Traditional French bakeries have been making these cookies for centuries using laminated dough similar to croissants. The technique of folding creates those signature layers that puff dramatically during baking. While my cinnamon version is somewhat Americanized the classic French version typically uses only sugar without additional spices letting the buttery pastry shine.
Storage and Freshness Tips
Palmiers are at their absolute best when eaten the same day they're baked when the exterior maintains its delicate crispness. If you need to store them place completely cooled palmiers in an airtight container with parchment paper between layers to prevent sticking. They'll stay reasonably crisp for about 24 hours. After that they'll still taste delicious but will gradually soften as they absorb moisture from the air. To refresh day old palmiers place them in a 300°F oven for 3 to 5 minutes which will restore some of their original texture.
Creative Variations
While the classic cinnamon version is hard to beat palmiers are incredibly versatile. Try replacing the cinnamon with other spices like cardamom ginger or pumpkin pie spice for seasonal variations. For a savory twist omit the sugar and cinnamon completely and instead spread the pastry with a thin layer of pesto cream cheese and grated parmesan. Another delicious option is adding finely chopped nuts like pistachios or hazelnuts to the sugar mixture for added texture and flavor. The basic folding technique remains the same regardless of your flavor choices.

Frequently Asked Questions
- → How can I ensure my palmiers turn out crispy?
Make sure to bake the palmiers until the sugar is fully caramelized and golden. Allow them to cool completely on a parchment-lined rack to maintain their crisp texture.
- → Can I make puff pastry from scratch?
Yes, but store-bought puff pastry works perfectly and saves time. If making your own, ensure you follow a proper laminating technique for flaky layers.
- → Why do I need to chill the pastry before slicing?
Chilling helps firm up the layers of dough and sugar, making it easier to slice cleanly and maintain the delicate shape during baking.
- → What type of sugar works best for palmiers?
Granulated white sugar is ideal as it caramelizes well during baking, creating a crisp and golden finish.
- → Can I customize the filling flavors?
Absolutely! You can experiment with other spices like nutmeg or cardamom, or add finely chopped nuts or cocoa powder to the sugar mixture for variation.
