Ingredients

Makes one 9×13-inch assembled mille-feuille (serves 8–10)

For the puff pastry layers

2 sheets store-bought puff pastry (thawed if frozen), or homemade if you insist
1 egg, beaten (for egg wash)
1 tablespoon granulated sugar (optional, for a slight caramelization)

For the vanilla pastry cream (crème pâtissière)

2 cups whole milk
1/2 cup granulated sugar
4 large egg yolks
1/4 cup cornstarch
2 tablespoons unsalted butter
1 1/2 teaspoons pure vanilla extract

For the whipped cream layer

1 cup heavy cream, cold
2 tablespoons powdered sugar
1/2 teaspoon vanilla extract
6–8 oz mascarpone (optional — makes it richer and more stable)

For assembly

12–16 oz fresh raspberries (plus a few extra for garnish)
2 tablespoons apricot jam, warmed and strained (optional glaze)
Powdered sugar for dusting

Equipment tip: a rimmed baking sheet, a sharp knife, a piping bag (or a zip-top bag with corner snipped), and a baking rack will make this easier.

Step-by-step Directions

Prep and bake the puff pastry

Preheat oven to 400°F (205°C). Line two baking sheets with parchment paper.
Unfold the puff pastry sheets on a lightly floured surface. Using a fork, dock the pastry all over (poke holes) to keep it from puffing into giant blisters. Trim to fit three even rectangles from the two sheets — you want three consistent layers that will stack neatly.
Place rectangles on the prepared sheets, brush lightly with the beaten egg, and sprinkle with the tablespoon of granulated sugar (optional). Cover with another sheet of parchment and a second baking sheet (or a heavy pan) to keep them flat while baking.
Bake 12–16 minutes, until golden and crisp. Remove the top sheet of parchment and cool completely on a rack. If edges brown too quickly, tent with foil.

Make the pastry cream
5. In a medium saucepan, heat milk over medium until it just begins to steam (don’t boil). In a bowl, whisk together sugar, egg yolks, and cornstarch until smooth and slightly pale.
6. Temper the eggs: slowly pour about 1/3 of the hot milk into the yolk mixture, whisking constantly, then return the warmed mixture back to the saucepan.
7. Cook over medium heat, whisking constantly, until thickened and bubbling — about 1–2 minutes after it starts to simmer. Remove from heat, whisk in butter and vanilla.
8. Transfer to a bowl, press a piece of plastic wrap directly on the surface to prevent a skin, and chill until fully cold (at least 1 hour).

Whip the cream
9. In a chilled bowl, beat the heavy cream, powdered sugar, and vanilla until soft peaks form. If using mascarpone, whip it briefly until smooth and fold into the whipped cream for extra stability and richness.

Assemble the Raspberry Thousand Layers
10. When pastry and pastry cream are cold, cut each pastry rectangle horizontally if they puffed up, or use as-is if flat. You’ll want three pancake-thin layers total.
11. Place the first pastry layer on your serving board. Spread (or pipe) a thin layer of pastry cream across it, then dot with fresh raspberries — some whole, some halved for better coverage.
12. Add the second pastry layer, press gently, then add a layer of whipped cream (or mascarpone cream) and more raspberries.
13. Top with the final pastry layer. Warm the apricot jam and brush a thin glaze over the top pastry for shine (optional). Dust with powdered sugar and garnish with a few whole raspberries.
14. Chill the assembled dessert for at least 30 minutes to let layers settle. Slice with a very sharp knife, wiping the blade between cuts, and serve.

Timing and make-ahead tips

Bake the puff pastry and make the pastry cream up to 2 days ahead; store wrapped and chilled.
Whip the cream the day you assemble for best texture.
Assembly can be done 2–4 hours ahead; the pastry will soften slightly, which actually makes the slices easier to eat.

Cooking Tips (Because Life Happens)

Use a sharp serrated knife and a gentle sawing motion when you slice; stabbing will crumble the layers.
If your puff pastry puffs unevenly, use the oven-top trick: place a second baking sheet on top of the pastry for the first 10 minutes of baking to keep it flat.
Don’t panic if your pastry cream has small lumps after chilling — a quick whisk while slightly warmed will smooth it right out.
For a faster version, swap pastry cream for a stabilized whipped cream (whip 1 cup heavy cream + 8 oz mascarpone + 1/3 cup powdered sugar), but know it changes the classic flavor profile.
Want a gluten-free option? Use thin gluten-free puff pastry and be mindful it may not rise as dramatically.

A Little Kitchen Story (From Me to You)

Patricia and I tested this recipe more times than I care to admit — mostly because every trial ended up with us taste-testing “just one more” slice. Once, we brought a tray to a neighborhood potluck and watched strangers argue over the last piece. That’s when I knew this layered raspberry dessert had the magic balance of elegant and totally approachable. It’s the kind of recipe that makes you look fancy without scheduling an entire afternoon to bake.

Serving Suggestions

Pair with a cup of strong coffee or a light rosé.
For brunch, serve smaller portions alongside fresh fruit and yogurt.
Top individual slices with a drizzle of dark chocolate if you want to lean in to decadence.

FAQs

Can I use frozen raspberries?

Yes. Thaw them and drain any excess liquid. Toss with a tiny bit of sugar if they taste tart. Frozen berries will be softer, so layer them carefully to avoid a watery mille-feuille.

Can I substitute store-bought pastry cream or pudding?

You can, but homemade pastry cream has a richer flavor and silkier texture. A high-quality store-bought vanilla pastry cream is a fine shortcut — just chill it fully before assembling.

How long will leftovers keep?

Store covered in the fridge for up to 2 days. Note: the pastry softens over time. If you love crisp layers, assemble close to serving time.

Can I make this nut-free or dairy-free?

Swap butter with a plant-based spread and use coconut cream-based whipped topping for a dairy-free version. For nut-free, avoid any almond-based pastry or decorations.

Is this the same as a raspberry mille-feuille or Napoleon?

Yes — "mille-feuille" and "Napoleon" are classic names for layered puff pastry desserts. Our Raspberry Thousand Layers is essentially a raspberry mille-feuille with a touch of homey simplicity.
