Step-by-Step Instructions
Step 1: Bake the Puff Pastry Layers
- Preheat oven to 400°F (200°C).
- Place puff pastry sheets on parchment-lined baking sheets.
- Prick all over with a fork to prevent puffing too much.
- Brush with egg wash (whisk together 1 egg and 1 tbsp milk).
- Place another piece of parchment and a second baking sheet on top to weigh it down.
- Bake for 15–18 minutes, until golden and crisp.
- Let cool completely, then trim edges and cut each sheet into 2 equal rectangles (you’ll have 4 total layers).
Step 2: Make the Vanilla Custard
- In a saucepan, heat the milk until just steaming—not boiling.
- In a bowl, whisk together sugar, cornstarch, egg yolks, and salt until smooth.
- Slowly pour the hot milk into the yolk mixture, whisking constantly to temper the eggs.
- Return the mixture to the saucepan and cook over medium heat, whisking constantly, until thickened (about 5–7 minutes).
- Remove from heat and stir in butter and vanilla.
- Transfer to a bowl, cover with plastic wrap (pressing it directly on the surface to prevent skin), and chill for at least 2 hours.
Step 3: Assemble the Cake
- Place one puff pastry layer on a serving plate.
- Spread or pipe a layer of chilled custard evenly over the top.
- Repeat with remaining layers, ending with the final pastry sheet on top.
- Press down gently to compact layers without squeezing out the custard.
Step 4: Chill & Finish
- Chill the assembled cake for at least 1 hour to set.
- Dust with powdered sugar before serving, or drizzle with icing or melted chocolate.
- Slice carefully using a serrated knife.

Tips for the Best Vanilla Custard Puff Pastry Cake
Use Cold Pastry – Chilled pastry layers are easier to work with and don’t soften the custard.
Keep Custard Thick – A thicker custard holds up better between flaky layers.
Use a Bench Scraper – It helps create clean, even slices.
Customize It – Add fruit, flavor extracts, or swap vanilla for citrus zest.
Make Ahead – Best served after chilling for a few hours or overnight.
Serving Suggestions
Serve with fresh strawberries, raspberries, or blueberries for a fruity contrast.
Add a dollop of whipped cream or a drizzle of caramel sauce.
Pair with coffee or hot tea for a lovely dessert course.
Dust with cinnamon sugar for a warm, spiced twist.
How to Store & Make Ahead
Storing:
Store leftovers covered in the refrigerator for up to 3 days. Puff pastry may soften slightly but will still taste amazing.
Make Ahead:
Bake the pastry and make the custard a day ahead. Assemble the morning of your event for best results.
Frequently Asked Questions
- Can I use instant pudding instead of homemade custard?
Yes, for a shortcut. Just use less liquid than directed to keep it firm enough to layer. - Will the puff pastry stay crispy?
It stays crispy for a few hours after assembly, then softens slightly but still tastes great. - Can I freeze this cake?
It’s not recommended, as the custard can separate when thawed. - Can I make mini versions?
Absolutely! Use small squares of puff pastry and pipe custard between them for individual desserts. - Is this the same as mille-feuille or Napoleon?
It’s very similar! This version uses fewer layers and a simpler assembly, but delivers the same creamy-crisp contrast.
