How to Make Spiced Pecan Palmiers

Follow these simple steps for perfectly crispy, caramelized cookies.

1. Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper .
2. Make the spiced pecan sugar. In a food processor, combine the pecans, sugar, cinnamon, cardamom (if using), and salt. Pulse until the pecans are finely ground and the mixture resembles wet sand .
3. Roll out the pastry. On a lightly floured surface, gently roll the thawed puff pastry into a 10×14-inch rectangle, smoothing out any creases .
4. Add the filling. Sprinkle about half of the spiced pecan mixture evenly over the pastry. Gently press it into the dough with your rolling pin .
5. Fold the pastry. Starting from one long edge, roll the pastry tightly toward the center. Repeat with the opposite long edge so both rolls meet in the middle, creating a log shape .
6. Chill thoroughly. Wrap the log in plastic wrap and refrigerate for at least 30 minutes until firm. This is essential for clean slicing and preventing shrinkage .
7. Slice and coat. Using a sharp knife, cut the chilled log into ½-inch thick slices. Dip both cut sides into the remaining spiced pecan mixture for extra flavor and crunch .
8. Bake for 15-18 minutes, or until the pastry is puffed and the sugar is deeply caramelized. Flip them halfway through for even browning .
9. Cool slightly on the baking sheet before transferring to a wire rack. They crisp up as they cool.

5 Tips for Perfect Spiced Pecan Palmiers

Keep everything cold. Puff pastry relies on cold butter. If the dough warms up while you’re working, pop it back in the fridge for 10 minutes. Cold butter = flaky layers.

Use freshly toasted pecans. Toasting the pecans before grinding brings out their nutty flavor. Just bake them at 180°C for 5-7 minutes until fragrant .

Don’t overfill. A thin, even layer of the spiced pecan mixture is all you need. Too much filling will make the palmiers difficult to roll and slice.

Use a sharp knife. A dull knife will crush the layers and compress the pastry. Use a sharp, serrated knife for clean, even slices .

Watch the baking time. Palmiers can go from golden to burnt very quickly. Start checking around 12 minutes and pull them out as soon as they’re deep golden brown .

3 Delicious Variations to Try

Maple Pecan Palmiers. Swap the sugar for maple syrup in the filling. Spread a thin layer of maple-pecan paste over the pastry before rolling for a rich, autumnal flavor .

Pecan and Cardamom Palmiers. Replace the cinnamon with ground cardamom and add the seeds from half a vanilla bean. The floral, citrusy notes of cardamom pair beautifully with pecans .

Mincemeat and Pecan Palmiers. For a festive twist, spread a thin layer of mincemeat over the pastry along with the spiced pecan mixture. This combines the best of Christmas flavors in one cookie .

How to Store and Reheat

Store baked palmiers in an airtight container at room temperature for up to 5 days. To keep them crisp, place a piece of parchment paper between layers .

For longer storage, freeze unbaked palmiers. Arrange the sliced palmiers on a baking sheet and freeze until solid. Transfer to a freezer bag and freeze for up to 3 months. Bake directly from frozen, adding 3-5 minutes to the baking time .

To reheat: Warm in a 180°C (350°F) oven for 3-5 minutes to bring back the crispiness. Avoid the microwave—it will make them soft.

Frequently Asked Questions

Why did my palmiers unroll in the oven?
This usually happens when the pastry log wasn’t chilled long enough. Make sure to chill for at least 30 minutes before slicing. Rolling too loosely can also cause them to separate .

Can I make these ahead of time?
Absolutely. You can assemble the palmiers up to the slicing stage, arrange them on a baking sheet, cover, and refrigerate for up to a day before baking. You can also freeze them unbaked for longer storage .

Why didn’t my palmiers puff up?
The most common causes are using warm pastry, an oven that isn’t hot enough, or not chilling the dough before baking. Always keep puff pastry cold and bake at 200°C (400°F).

Can I use a different nut?
Yes! Walnuts, almonds, or hazelnuts all work beautifully. Just toast them first and grind them with the sugar and spices .

Are palmiers best served warm or cold?
Palmiers are delicious both ways. They’re at their most crisp and flavorful warm from the oven, but they also make wonderful room-temperature treats for parties and gifting.
