Gruyère & Apple Puff Pastry Pinwheels (The Flaky Spiral)
Roll it. Slice it. Bake it. Your new favorite weekend snack is a spiral.
Light but decadent — buttery flaky pastry wound tight around sharp nutty Gruyère and caramelized tart apple, baked until the cheese bubbles and the edges char just enough to be perfect.
INGREDIENTS
The Base
1 sheet ready-made all-butter puff pastry (320g / 11 oz), thawed
1 egg yolk + 1 tbsp milk (for egg wash)
1 tbsp demerara sugar (for finishing)
Gruyère Layer
180g / 6.5 oz Gruyère, finely grated
1 tsp Dijon mustard (5 ml)
¼ tsp cracked black pepper (1.25 ml)
¼ tsp garlic powder (1.25 ml)
Pinch of fine sea salt
Apple Layer
2 medium tart apples (Granny Smith), peeled, cored, sliced paper-thin on a mandoline
1 tbsp fresh lemon juice (15 ml)
1 tbsp caster sugar (15 ml)
½ tsp cinnamon (2.5 ml)
Pinch of fine salt
Finishing
Fresh thyme leaves
Thin honey drizzle
Flaky sea salt
Extra cracked black pepper
INSTRUCTIONS
Toss the paper-thin apple slices with lemon juice, caster sugar, cinnamon, and a pinch of salt in a bowl. Set aside 10 minutes — the lemon stops browning and the sugar begins softening the slices so they roll without cracking.
Pat the apple slices completely dry between two layers of paper towel — excess moisture turns the pastry soggy from the inside.
Unroll the cold puff pastry sheet on a lightly floured surface. Keep it cold — warm pastry becomes greasy and loses its layers.
Spread a thin, even layer of Dijon mustard across the entire pastry surface using the back of a spoon.
Mix the grated Gruyère with cracked black pepper, garlic powder, and salt. Scatter evenly across the mustard layer, leaving a 2cm / ¾ inch bare strip along one long edge — this will be the sealing edge.
Lay the dried apple slices in a single, slightly overlapping layer over the cheese, covering the full surface up to the bare edge.
Starting from the long edge opposite the bare strip, roll the pastry tightly and evenly into a firm log — keep tension in the roll so no air pockets form between the layers.
Press the bare edge firmly against the log to seal. Wrap tightly in cling film and refrigerate 30 minutes — a cold log slices cleanly without compression.
Preheat oven to 200°C / 390°F. Line two baking trays with parchment paper.
Remove the chilled log and slice into rounds 2cm / ¾ inch thick using a sharp serrated knife — use a gentle sawing motion, no downward pressure, to keep the spiral intact.
Lay each pinwheel flat on the lined trays with at least 4cm / 1.5 inches of space between them — they expand significantly as the pastry puffs.
Brush the tops generously with egg wash. Scatter demerara sugar lightly across the tops — it caramelizes into a crackling amber glaze during baking.
Bake 18–22 minutes until the spirals are puffed, deeply golden, and the Gruyère is visibly bubbling at the edges of every layer.
Remove from the oven and cool on the tray 5 minutes — the cheese re-sets slightly and the caramel firms into a glossy crust.
Transfer to a matte white plate. Scatter fresh thyme leaves across the plate.
Drizzle a thin line of honey over every pinwheel in slow, sweeping passes. Finish with a pinch of flaky salt and cracked black pepper.
Serve warm — pull one apart at the table so the cheese stretch and the caramelized apple layers are visible. Spring is here! And it smells like brown butter, Gruyère, and caramelized apple.
