Cross-Contamination Warning for Gluten-Free Mille-Feuille: When preparing this desserts recipe, store-bought puff pastry is usually made with flour that contains gluten, so only use one labeled gluten-free. Roll between parchment rather than on a floured wooden board. Flour dust travels. Bake this on a day the kitchen is not also handling flour that contains gluten, use clean bowls, beaters and baking sheets, and keep the gluten-free flour blend in its own sealed container.

Gluten-Free Notes for Gluten-Free Mille-Feuille: The rough puff pastry uses a gluten-free all-purpose flour blend and xanthan gum, and the pastry cream is thickened with cornstarch. Use cornstarch, powdered sugar, chocolate, vanilla and a flour blend labeled gluten-free. A store-bought puff pastry labeled gluten-free also works.

Instructions

1 For the pastry cream, heat the milk until steaming. Whisk the yolks, sugar and cornstarch in a bowl, then slowly whisk in the hot milk. Return to the pan and cook over medium heat, whisking constantly, until it boils and thickens, then cook 1 minute more. Off the heat, whisk in the butter and vanilla. Press plastic wrap onto the surface and chill until cold, at least 2 hours.
2 For the pastry, whisk the gluten-free flour blend, xanthan gum (if using), 1 tsp sugar and salt. Toss in the cold butter and press each cube flat between your fingers, leaving large flakes. Drizzle in ice water and toss until the dough just holds together. Pat into a rectangle, wrap and chill for 30 minutes.
3 Roll the dough between floured parchment into a 6x15-inch rectangle and fold it in thirds like a letter. Turn it a quarter turn, roll and fold again. Chill for 30 minutes, then repeat for two more folds and chill for 30 minutes more.
4 Preheat the oven to 400°F (200°C). Roll the pastry between parchment into a 12x15-inch rectangle about 1/8 inch thick. Slide it, on the bottom parchment, onto a baking sheet, prick it all over with a fork and chill for 15 minutes.
5 Cover the pastry with a second sheet of parchment and set another baking sheet on top. Bake for 20 minutes, then remove the top sheet and paper and bake 10-15 minutes more, until deep golden and crisp all the way through. Cool completely.
6 Trim the edges and cut the pastry crosswise into three 4x12-inch strips with a serrated knife.
7 Whisk the powdered sugar with enough milk to make a thick, spreadable icing. Spread it over the flattest strip. Pipe thin lines of melted chocolate across the icing and drag a toothpick through them in alternating directions to feather. Let set.
8 Whisk the cold pastry cream smooth. Spread half over one plain strip, top with the second plain strip, spread with the rest, and set the iced strip on top. Chill for 1 hour, then cut into 8 slices with a serrated knife.

Tips & Notes

Bake the mille-feuille pastry under a second baking sheet for the first 20 minutes. The weight keeps the layers flat and even so they stack neatly.
Bake the pastry until it is deep golden in the center. Pale gluten-free pastry turns soft under the pastry cream within an hour.
Assemble the mille-feuille no more than a few hours before serving and use a gentle sawing motion with a serrated knife to cut it.

Common questions

How do you keep the mille-feuille pastry sheets flat and crisp?

Prick the rolled pastry all over, chill it 15 minutes, then cover it with parchment and a second baking sheet and bake 20 minutes at 400°F (200°C). Remove the top sheet and paper and bake 10 to 15 minutes more, until deep golden and crisp all the way through. Pale pastry turns soft under the pastry cream within an hour.

How far ahead can the mille-feuille be assembled?

Make the pastry cream first, since it needs at least 2 hours to chill. Assemble no more than a few hours before serving: spread half the cold, whisked cream on one strip, add the second strip and the rest of the cream, top with the iced strip, chill 1 hour, then cut 8 slices with a serrated knife using a gentle sawing motion.
