Cinnamon Palmiers
Puff pastry rolled in sugar and folded into a heart shape — as much caramelised candy as pastry.
What's going on here
Palmiers work because sugar, unlike flour, is pressed directly onto the outside of the pastry and rolled in rather than folded inside it, so every exposed layer edge is coated. In the oven, that surface sugar first dissolves in the moisture released from the pastry's butter, then as the water evaporates it recrystallises and eventually caramelises against the hot pan, giving each spiral a glazed, faintly crunchy shell around the flaky layers underneath. Cinnamon rolled in alongside the sugar behaves the same way any bloomed spice does against direct heat, its aromatic oils intensifying rather than just sitting inertly on the surface. Because the sugar is caramelising directly against the baking sheet, these need to be flipped partway through so both faces get equal contact and equal colour — left on one side the whole time, the bottom scorches long before the top has caramelised at all.
Ingredients
Pastry
- 1 lbRough puff pastry or store-bought puff pastry
thawed if frozen
Coating
- 1 cupGranulated sugar
- 2 tbspGround cinnamon
Instructions
Prep
- Stir the sugar and cinnamon together and spread half of it on a clean work surface.
Shape
- Roll the pastry out on the sugared surface, sprinkling more sugar on top as you go, into a rectangle about 12x10 inches, pressing the sugar into both sides.
Tip: Get a generous, even coating everywhere — bare patches of pastry won't caramelise or hold together as neatly.
- Fold both long edges in to meet at the centre, then fold each of those halves in again to meet at the centre, then fold the whole thing closed like a book, so you have six layers stacked.
Tip: Chill for 15 minutes if the pastry gets too soft to fold cleanly at any point — cold pastry holds a crisp fold far better than warm.
Chill
- Wrap and chill the folded log until firm.
Slice
- Slice into 1/2-inch pieces and lay flat, cut-side down, on a lined baking sheet, spaced well apart — they spread significantly.
Bake
- Bake at 200°C (400°F) until the bottoms are deeply caramelised, then flip each one over and continue baking until the second side is caramelised too.
Tip: Watch closely once you flip — the sugar can go from perfectly caramelised to burnt in under a minute.
Cool
- Cool on a rack — they firm up and crisp further as they cool.

How well the formula holds up against known working ratios.
Whether the method builds flavor or merely combines ingredients.
How deliberately moisture, gluten, starch, and fat are controlled.
How much margin for error the recipe leaves a home cook.
Whether you can make it from staples, right now, with normal gear.
Correctly treats the surface sugar coating as candy-making, not just flavouring, which explains both the shine and the burn risk. Genuinely easy to scorch, hence the reliability mark.
Scored on the science of cooking — ratios, flavour development, texture control, how forgiving the method is, and whether you can make it from what's in the cupboard. Not a measure of how much you'll like it.
Tips for this recipe
Bottoms burned before the tops caramelised
That's exactly why the flip exists. If it's still happening, drop the oven 10–15°C and watch the first batch closely to recalibrate your timing.
Stuck to the pan
Caramelised sugar sets hard as it cools and grips whatever it's touching. Parchment paper, not a bare sheet, is what lets these release cleanly once cool.
