Prep 40 min

Cook 30 min

Serves 6

Ingredients

500 g puff pastry (storebought or homemade)

500 ml whole milk

120 g sugar

40 g cornstarch

4 egg yolks

1 vanilla bean or 2 tsp vanilla extract

40 g unsalted butter (for custard)

150 g powdered sugar (for icing)

20 g dark chocolate (for classic swirl)

2–3 tbsp water (for icing)

Key Beginner Tips Before You Start

• Use storebought puff pastry if you're new — it’s reliable and saves hours.
• Keep everything cold: warm pastry becomes sticky and loses its layers.
• Dock (poke) the pastry with a fork so it stays flat instead of puffing wildly.
• Weigh down the pastry while baking (a second baking tray on top) for perfectly even layers.
• Chill the custard fully before assembling — warm cream will make the pastry soggy.
• Assemble just before serving for maximum crispness.

Instructions

• Prepare the pastryPreheat oven to 200°C. Roll puff pastry to a 3–4 mm sheet. Transfer to a tray lined with parchment.
• Dock and weigh downPrick the pastry all over with a fork. Place another sheet of parchment on top and a second baking tray to keep it flat.
• BakeBake 20–25 min until golden. Remove the top tray for the last 5 min to crisp. Cool completely.
• Make the custardHeat milk and vanilla until steaming. In a bowl, whisk yolks, sugar, and cornstarch. Slowly pour in hot milk while whisking.
• ThickenReturn mixture to the pot and cook on medium, whisking constantly, until thick. Remove from heat and whisk in butter.
• ChillCover custard with plastic wrap touching the surface and chill until cold.
• Cut pastry layersTrim edges and cut pastry into three equal rectangles.
• AssembleSpread half the custard on the first pastry layer, top with the second layer, add remaining custard, then finish with the third layer.
• Make icingMix powdered sugar with a little water to make a thick white glaze. Melt chocolate separately.
• DecorateSpread white icing on top. Pipe thin chocolate lines and drag a toothpick across to create the classic chevron pattern.
• Chill and serveRefrigerate 1 hour for clean slicing. Cut with a hot, sharp knife.

✔ Keep layers ultracrisp

• Bake the pastry fully golden, not pale — underbaked pastry softens quickly.
• If it softens during assembly, pop the whole dessert in the fridge to firm up.

✔ Make the custard silky

• Whisk constantly to avoid lumps.
• If lumps appear, strain the custard while still warm.

✔ Achieve clean, bakerystyle slices

• Use a serrated knife and gentle sawing motion.
• Wipe the blade between cuts.
• Chill the assembled pastry at least 1 hour.

✔ Flavor variations (beginnerfriendly)

• Add ½ tsp almond extract to the icing.
• Fold 100 g whipped cream into the custard for a lighter crème diplomate.
• Add thin layers of fresh raspberries or strawberries.
