French Palmier Cookies

Please share this post with your friends 🤗

I fell for palmiers the first time I bit into one: that perfect marriage of crisp, caramelized sugar and buttery, flaky puff pastry. They feel fancy but are deceptively simple — a few ingredients, minimal technique, and a little patience. These cookies are one of my go-to recipes when I need an elegant treat without a long ingredient list or complicated steps.

This version leans on a store-bought puff pastry sheet so you can focus on the fun part: rolling sugar into delicate, heart-shaped rounds and watching them bloom in the oven. The result is a batch of golden, crunchy palmiers with a tender inside. They store well and travel even better, which makes them great for gifts or an afternoon coffee break.

What’s in the Bowl

Ingredients

½ cup granulated sugar — provides the caramelized crunch and sweetness; half is used under the pastry and half on top to coat both sides.

Pinch salt — enhances flavor and balances the sweetness.

1 sheet puff pastry — the base of the palmiers; choose a high-quality, fully thawed sheet for best flakiness.

French Palmier Cookies: From Prep to Plate

Step-by-step Instructions

Line an 18 x 13-inch baking sheet with parchment paper and set aside. Preheat your oven to 425°F (220°C) when you’re ready to bake.

In a small bowl, mix the ½ cup granulated sugar with a pinch of salt until evenly combined.

Sprinkle about half of the sugar-salt mixture onto a clean work surface, spreading it into a rough rectangle about the size of your puff pastry sheet.

Unfold or roll out the 1 sheet puff pastry on top of the sugar on the counter. Sprinkle the remaining sugar-salt mixture evenly over the top side of the pastry.

Using a rolling pin, gently roll the pastry once or twice to press the sugar into both sides of the dough and to flatten the sheet slightly. Be gentle — you want to press in the sugar, not compress all the layers.

With the long edges of the pastry facing you, tightly roll one long edge toward the center until it reaches the middle. Repeat with the other long edge so both rolls meet in the center.

Once both sides are rolled to the center, press the two roll edges together gently so the log holds its shape.

Wrap the sugar-coated pastry roll tightly in plastic wrap (Glad Wrap) and chill. Freeze for 30 minutes for a quick set, or refrigerate for 1 hour if you prefer a slower chill.

After chilling, remove the wrapped roll and unwrap it. Use a sharp paring knife to cut the roll into ½-inch-wide slices. Arrange the slices on the prepared baking sheet, leaving at least 2 inches (5 cm) of space between them to allow for spreading.

Bake the palmiers in the preheated 425°F (220°C) oven for 10–12 minutes, until they are golden brown on the bottom and beginning to caramelize.

Carefully flip each palmier using a metal spatula or palette knife, then return the sheet to the oven and bake for an additional 4–6 minutes until both sides are evenly golden and crisp.

Transfer the baked palmiers to a cooling rack and allow them to cool completely. The sugar will set as they cool, producing the signature crisp finish.

Why This Recipe is a Keeper

They look fancy but you don’t need to be a pastry chef to get great results. Using a thawed puff pastry sheet and a little sugar gives you layered crunch and caramel without complicated laminating. The chilling step is the secret: it firms the roll so clean slices hold their shape and bake evenly. Once you’ve made them once, you’ll find yourself coming back for the comforting rhythm of rolling, slicing, and popping golden hearts into the oven.

Substitutions by Category

Sugar — Use superfine granulated sugar if you have it; it melts and caramelizes quickly. You can also try a light sprinkle of cane sugar for a slightly different crunch.

Salt — Kosher salt or fine sea salt both work. If you prefer a less pronounced savory balance, reduce the pinch.

Puff pastry — Any high-quality, pre-rolled sheet is fine. For a richer flavor, use butter-based puff pastry rather than margarine-based options.

Kitchen Gear Checklist

Baking sheet (18 x 13 inch recommended) — provides even baking space for multiple palmiers.

Parchment paper — prevents sticking and helps with clean flipping.

Rolling pin — presses sugar into the pastry without crushing layers.

Sharp paring knife — essential for clean, even ½-inch slices.

Plastic wrap (Glad Wrap) — to chill and hold the roll shape before slicing.

Metal spatula or palette knife — used to flip cookies halfway through baking.

Cooling rack — cools cookies quickly for crisp texture.

Learn from These Mistakes

Cutting slices too thin or too thick — aim for consistent ½-inch slices. Too thin means burnt edges; too thick prevents even baking.

Skipping the chill — unchilled logs squash and smear when sliced, and the palmiers spread into flat pancakes while baking.

Over-pressing with the rolling pin — press just enough to embed the sugar. Overworking compresses the pastry layers and reduces flakiness.

Not leaving space on the tray — palmiers need at least 2 inches/5 cm between them to puff and caramelize properly.

Smart Substitutions

If you want a lightly flavored variation, add a thin layer of ground cinnamon to the sugar before sprinkling. Use sparingly so the sugar can still caramelize cleanly.

For a less-sweet version, reduce total sugar by a couple of tablespoons, but keep enough to get that caramelized crust.

To make mini palmiers for bite-sized treats, slice thinner than ½ inch, but watch the bake time closely — they’ll brown faster.

Notes from the Test Kitchen

I tested this recipe with both rapid freezing (30 minutes) and a 1-hour refrigeration chill. Both produced good results; the freezer method is perfect when short on time and gives very clean slices. The 1-hour fridge chill gives slightly more relaxed handling and similar caramelization. I recommend a sharp, sturdy paring knife — a serrated blade makes ragged edges and a dull knife smashes the roll.

Baking at 425°F (220°C) on the top rack produces the best caramelization on the sugar. The flip halfway through is crucial: it ensures both sides are evenly caramelized and crisp. If your oven runs hot, check at the lower end of the time windows to avoid burning the sugar.

Cooling, Storing & Rewarming

Cooling — Transfer to a wire rack and cool completely; the sugar will harden and the palmiers will crisp as they cool.

Storing — Keep cooled palmiers in an airtight container at room temperature for up to 4 days. Place parchment between layers to prevent sticking.

Rewarming — Warm briefly in a 300°F (150°C) oven for 3–4 minutes if you want to refresh the crispness. Avoid microwaving, which makes them soggy.

Your Top Questions

Can I make palmiers ahead? — Yes. After baking, store them in an airtight container for up to 4 days. You can also freeze baked palmiers for up to 1 month; re-crisp in a warm oven.

Can I use frozen puff pastry? — Use fully thawed puff pastry for even rolling and proper rise. Work with it cold but pliable, not rock-hard.

Why did mine flatten? — Likely because the roll wasn’t properly chilled or the slices were cut too thin. Chill and slice consistently at ½ inch.

Can I add fillings? — Traditional palmiers are plain sugar-coated. You can experiment with cinnamon or a light sprinkle of finely chopped nuts, but keep additions minimal so the sugar caramelizes.

Hungry for More?

If you enjoyed making palmiers, try other quick puff pastry treats: cinnamon pinwheels, jam-filled turnovers, or savory cheese straws. They all use the same approachable technique with just a few add-ins to transform them into something new. Keep a bag of puff pastry in your freezer — it’s a small shortcut that makes impressive biscuits, tarts, and cookies when you want something pretty with minimal fuss.
