Sweet Crunchy Sugar Cookies are the ultimate quick fix when your sweet tooth strikes and you want something flaky and caramelized. With just a handful of basic ingredients and almost no prep, these golden pastries transform into crisp, melt in your mouth treats that never last long on my kitchen counter.
I have made these for last minute gatherings more than once and there is never a crumb left by the end of the night. My sister always asks for the recipe so she can make them with her kids on rainy afternoons.
Ingredients
- Puff pastry sheet: Ensures buttery layers and shatteringly crisp texture for best results choose an all butter variety from the freezer section
- Granulated sugar: Brings not just sweetness but essential crunch as it caramelizes in the oven sift to remove lumps and ensure even coating
- Ground cinnamon: Adds aromatic warmth and a nostalgic cookie shop aroma fresh cinnamon packs more punch so check that your ground spice is fragrant
Step-by-Step Instructions
- Mix Cinnamon Sugar:
- Combine cinnamon and sugar in a small bowl using a fork to fully mix the spice through the sugar so you get even flavor in every bite
- Sugar the Pastry:
- Spread two tablespoons of the cinnamon sugar evenly over the surface of the thawed puff pastry then use a rolling pin to press the sugar in lightly so it sticks and infuses the layers
- Flip and Repeat:
- Carefully flip the pastry over and repeat with two more tablespoons of cinnamon sugar rolling again to embed the sugar into the new surface
- First Folds:
- Fold each long edge of the pastry halfway to the center creating a rectangle then gently roll the pastry to flatten and press together without squishing the layers
- Second Folds:
- Fold the new edges in so they meet exactly at the center line once more then sprinkle half of the remaining cinnamon sugar over these new folds and roll gently to fuse the sugar
- Final Fold:
- Now fold the pastry in half along the length so you end up with six layers chill in the fridge for fifteen minutes to firm up and make slicing easier
- Preheat Oven:
- Heat your oven to four hundred degrees Fahrenheit so you are ready to bake just as the dough is chilled
- Slice and Sugar:
- Slice the chilled pastry log into one centimeter strips then press the cut edges into the rest of your cinnamon sugar mix so each cookie will have crunchy caramelized sides
- Arrange on Tray:
- Space the strips about two inches apart on a parchment lined baking tray since they puff up a lot as they bake
- Bake:
- Bake for fourteen minutes watching for the edges to get deeply golden and the sugar to bubble and caramelize flip each strip with a spatula and bake four minutes longer until evenly golden all over
- Cool Down:
- Transfer all the cookies to a rack lined with parchment and let them cool fully the sugar hardens and makes an irresistible crunch

My favorite part is how the sugar caramelizes on the outside while staying flaky inside. The cinnamon smell fills the whole kitchen and always reminds me of childhood holiday mornings.
Storage Tips
Let your cookies cool completely before storing to keep them crisp. Layer them between sheets of parchment in an airtight tin at room temperature. If they lose their snap just warm them in a low oven for a few minutes to revive the crunch.
Ingredient Substitutions
You can use brown sugar for a toasty caramel flavor or swap cinnamon for ground cardamom or pumpkin spice. If you only have margarine based puff pastry the texture will still be delicious though slightly less rich.
Serving Suggestions
Pile these cookies high on a platter for afternoon tea dip the ends in melted chocolate for parties or serve alongside a bowl of vanilla ice cream for a quick dessert. They pair beautifully with coffee or chai on a chilly day.
Cultural Context
This style of cookie traces its inspiration to French palmiers and Spanish palmeras both beloved for their crisp caramelized edges. Making them at home always transports me to European bakeries.

These cookies are fast, cheerful, and vanish in no time. You will want to bake a double batch every time!
