Religieuses are two-tiered choux pastries — a large puff stacked with a small one — filled with vanilla pastry cream and finished with chocolate ganache. They take about two and a half hours start to finish, and most of that time is hands-on. The honest reason to make them: they look genuinely impressive, they hold their shape well once assembled, and a box of four makes a gift that no store-bought cookie tin can touch.
Smart swaps
- Dark chocolate: The ganache calls for dark chocolate. Anything between 60–70% cacao works well. Avoid baking chips — they contain stabilizers that make ganache grainy.
- Whole milk: The pastry cream needs whole milk for the right body. Lower-fat milk produces a thinner cream that won’t hold inside the choux.
- Cornstarch + flour combo: Both thickeners are intentional. The flour adds stability for slicing and stacking; the cornstarch keeps the cream smooth. Don’t swap one out entirely.
- Eggs at room temperature: Cold eggs added to warm choux dough can seize the batter. If you forgot to take them out early, set them in warm water for 10 minutes.
The short version of why this works
Two things actually determine whether this recipe succeeds. First, cooking the flour in the butter-water mixture long enough to dry it out — you’re looking for a thin film on the bottom of the pan and a dough that pulls cleanly into a ball. Under-dried dough absorbs the eggs poorly and bakes flat. Second, the pastry cream must be cooked past the point where it looks done. Keep whisking over heat until it thickens noticeably and a few slow bubbles break the surface; that’s the starch fully activating. Pull it too soon and it stays loose, soaks through the choux, and makes the whole assembly soggy within an hour.
If something goes sideways
- Choux puffs collapsed after baking: They were underbaked or the oven was opened too early. Next time, bake until deep golden — pale choux will always collapse. Poke a small hole in the base of each puff immediately out of the oven to let steam escape.
- Ganache is too thick to dip: Reheat it gently over a double boiler, stirring in a teaspoon of warm cream at a time until it’s fluid enough to coat smoothly.
- Pastry cream has lumps: Push it through a fine-mesh sieve while it’s still warm. Lumps are usually cooked egg — straining fixes it completely.
- Small puff keeps sliding off the large one: The ganache on the large puff needs to be slightly tacky, not fully set, when you place the small puff on top. If both are fully set, a tiny dot of fresh ganache acts as glue. Skip the extra piped buttercream collar — not worth the extra dish, and the ganache seal holds fine on its own.
- Filling leaks out after piping: The pastry cream was too warm when piped. It should be fully chilled and firm — at least 2 hours in the fridge — before you fill the choux.
Keeping it fresh
Fully assembled religieuses keep in the refrigerator for up to 2 days in an airtight container; after that the choux softens noticeably. For gifting, assemble the day before and refrigerate overnight — they’re actually easier to handle once the ganache has fully set. If you want to get ahead, the pastry cream can be made up to 3 days in advance and stored with plastic wrap pressed directly against the surface. Unfilled, baked choux shells freeze well for up to 1 month in a zip-lock bag; re-crisp them in a 325°F oven for 5 minutes and cool completely before filling. Do not freeze assembled religieuses — the pastry cream weeps on thawing.
Religieuses (Cream-Filled Pastries)
Equipment
- Oven
- Baking sheet
- Piping Bag with Round Nozzle
- Mixing Bowls
- Whisk
- Saucepan
Ingredients
Choux Pastry
- 1 cup water preferably filtered
- ½ cup unsalted butter cut into cubes
- 1 tablespoon sugar
- ¼ teaspoon salt
- 1 cup all-purpose flour sifted
- 4 large eggs at room temperature
Pastry Cream
- 2 cups whole milk
- ½ cup sugar
- 2 tablespoons cornstarch
- 1 tablespoon all-purpose flour
- 4 large egg yolks
- 2 teaspoons vanilla extract pure
- 2 tablespoons unsalted butter
Chocolate Ganache
- 4 ounces dark chocolate finely chopped
- ½ cup heavy cream
Instructions
For the Choux Pastry:
- Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper.
- In a saucepan over medium heat, combine water, butter, sugar, and salt. Stir until butter melts completely.
- Add the flour all at once and stir vigorously with a wooden spoon until the mixture forms a ball and pulls away from the sides of the pan.
- Transfer the dough to a mixing bowl. Let it cool slightly. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
- Transfer the dough into a piping bag fitted with a round nozzle. Pipe small rounds for the top and larger rounds for the base onto the baking sheet. Bake for 25-30 minutes or until puffed and golden. Cool on wire racks.
For the Pastry Cream:
- In a saucepan, combine milk and half the sugar. Bring to a simmer.
- In a bowl, whisk together the remaining sugar, cornstarch, flour, and egg yolks until smooth.
- Gradually whisk the hot milk into the egg mixture. Return to saucepan and cook over medium heat, stirring constantly until thickened.
- Remove from heat, stir in vanilla and butter until smooth. Cool before using.
For the Chocolate Ganache:
- Heat the cream in a saucepan until it just begins to simmer.
- Pour over the chopped chocolate. Let sit for a minute then stir until smooth.
Assembly:
- Fill a piping bag with cooled pastry cream, pierce each choux and fill.
- Dip the tops of the choux in chocolate ganache. Stack small choux on top of larger ones.
- Optional: Decorate further with piped frosting or whipped cream if desired.
Notes
- For a richer flavor, use a high-quality vanilla bean instead of extract by infusing it with the milk.
- For a lighter cream, fold in some whipped cream gently before filling.

Common questions
Can I make religieuses the day before serving?
Yes — assembling the day before is actually ideal. The ganache sets firmly overnight in the fridge, which makes the pastries easier to package and transport without the top puff shifting.
How do I know when the choux is the right consistency before piping?
Lift the spoon or spatula and let the dough fall — it should drop slowly and form a thick V-shape or ribbon that holds for a second before breaking. If it falls off in chunks, beat in a little more egg; if it pours off, the dough is too loose to pipe into rounds.
My oven runs hot. Any adjustments?
Start checking at 22 minutes rather than 25. The target is a deep amber color all over, not just on top — pale sides mean the interior is still steamy and the puff will collapse when cooled.
Can I use a different flavor for the pastry cream?
Espresso works well — dissolve 1 teaspoon of instant espresso powder in the warm milk before tempering. Just keep the ganache chocolate rather than switching both components at once, or the flavors compete.
