Ingredients

Gluten-Free Pastry Layers

1 package gluten-free puff pastry (thawed if frozen)
2 tablespoons powdered sugar (for dusting before baking)

Caramelized Apple Filling

3 medium apples (Honeycrisp or Granny Smith), thinly sliced
2 tablespoons unsalted butter
3 tablespoons granulated sugar
½ teaspoon cinnamon
1 tablespoon lemon juice

Vanilla Custard (Pastry Cream)

2 cups whole milk
½ cup granulated sugar
3 large egg yolks
2 tablespoons cornstarch
1 tablespoon unsalted butter
1 tablespoon pure vanilla extract (or seeds from 1 vanilla bean)
Pinch of salt

For Assembly

Powdered sugar for dusting
Optional: thin apple slices for garnish

Instructions

Step 1: Prepare the Puff Pastry

Preheat your oven to 400°F (200°C).
Roll out the gluten-free puff pastry on a lightly floured surface.
Cut into equal rectangles (about 3×5 inches).
Place on a parchment-lined baking sheet.
Prick gently with a fork to prevent excessive puffing.
Lightly dust with powdered sugar.
Bake for 15–18 minutes until golden and crisp.
Cool completely on a wire rack.

Step 2: Make the Caramelized Apples

Melt butter in a skillet over medium heat.
Add sliced apples, sugar, cinnamon, and lemon juice.
Cook for 6–8 minutes until apples are tender but not mushy.
Allow to cool completely.

Step 3: Prepare the Vanilla Custard

Heat milk in a saucepan until just steaming (do not boil).
In a bowl, whisk egg yolks, sugar, cornstarch, and salt until smooth.
Slowly pour warm milk into the egg mixture while whisking.
Return mixture to saucepan and cook over medium heat.
Stir constantly until thickened (about 3–5 minutes).
Remove from heat and stir in butter and vanilla.
Cover with plastic wrap directly on the surface to prevent a skin.
Chill for at least 1 hour.

Step 4: Assemble the Mille-Feuille

Place one pastry rectangle on a plate.
Spread a generous layer of vanilla custard.
Add a layer of caramelized apples.
Top with another pastry sheet.
Repeat layers, finishing with pastry on top.
Dust with powdered sugar.
Chill 20–30 minutes before serving for cleaner slices.

Expert Tips for Perfect Layers

Keep Pastry Crisp

Assemble shortly before serving to prevent sogginess. You can store components separately and assemble when ready.

Chill the Custard Properly

A fully chilled custard spreads more easily and holds its shape.

Slice with a Serrated Knife

Use a gentle sawing motion to preserve the layers.

Variations

Salted Caramel Apple Version

Drizzle salted caramel sauce between layers for extra indulgence.

Dairy-Free Option

Use almond milk and dairy-free butter for the custard.

Spiced Autumn Edition

Add nutmeg and cloves to the apple filling for a deeper fall flavor.

Berry Twist

Add thin layers of raspberries between custard and apples for brightness.

Serving Suggestions

This elegant apple dessert pairs beautifully with:

Freshly brewed coffee
Earl Grey tea
Sparkling apple cider
Vanilla bean ice cream

Serve chilled but not overly cold — about 10 minutes at room temperature allows flavors to shine.

Storage Tips

Store assembled mille-feuille in the refrigerator for up to 2 days. For best texture, store pastry separately from custard and apples and assemble fresh.

Nutritional Benefits

Apples provide fiber and antioxidants. Using gluten-free puff pastry makes this suitable for those with gluten intolerance while still delivering indulgent flavor.

Cultural Context

Mille-feuille originated in France in the 17th century and has since become a symbol of pastry artistry. This gluten-free apple version blends classic European technique with modern dietary needs, making it accessible and inclusive.
