How to Make Chocolate Choux Buns
-
Heat the milk in a saucepan over medium heat until it just begins to steam, but don’t let it boil. This step is essential as it will create the base for your luscious chocolate pastry cream.
-
Whisk together the egg yolks, caster sugar, and cornstarch in a bowl until the mixture is completely smooth and pale. This creates a lovely base for your creamy filling.
-
Pour the hot milk into the egg mixture slowly, whisking continuously to combine, preventing the eggs from scrambling. This process ensures a smooth and velvety texture for your custard.
-
Return the mixture to the saucepan and cook over medium heat, stirring continuously until it thickens to a pudding-like consistency, about 3-5 minutes. Look for it to bubble gently and coat the back of a spoon.
-
Remove from heat and stir in the chopped dark chocolate until melted and smooth. This will give your pastry cream its rich and delightful chocolate flavor.
-
Mix the plain flour, cocoa powder, softened butter, and brown sugar in a bowl until fully combined for the chocolate craquelin, ensuring a sweet crunch on top of your buns.
-
Roll out the craquelin mixture on a lightly floured surface and cut into small pieces to place on top of your choux pastry before baking. This adds a delightful texture!
-
Boil the water, 50 gr butter, and 20 gr caster sugar together in a saucepan, stirring until the butter is melted. This mixture will create a shiny base for your choux pastry.
-
Remove from heat and stir in the plain flour and cocoa powder all at once until a smooth dough forms. It should pull away from the sides of the pan easily.
-
Incorporate the eggs one at a time into the dough, mixing well after each addition until fully combined and glossy. The dough should be smooth and shiny, an indicator of perfect choux.
-
Pipe the choux pastry onto a baking sheet lined with parchment paper, using a piping bag for neat, uniform shapes. Top each with a piece of the craquelin for an extra touch.
-
Bake in a preheated oven until puffed and golden brown, about 20-25 minutes at 375°F (190°C). Don’t open the oven door during baking to ensure they rise beautifully!
Optional: Dust with powdered sugar before serving for an elegant finish.

Tips for the Best Chocolate Choux Buns
Temperature Matters: Ensure that both your eggs and butter are at room temperature. This helps create a homogenous dough, leading to perfectly risen chocolate choux buns.
Avoid Scrambling: When adding hot milk to the egg mixture, whisk continuously and slowly pour the milk to prevent cooking the eggs. This ensures a smooth and silky pastry cream.
Proper Mixing: When incorporating the eggs into the choux pastry dough, mix until the dough becomes glossy and smooth. This is crucial for achieving the airy texture that makes your chocolate choux buns irresistible.
Don’t Rush Baking: Resist the urge to open the oven door while baking. This can cause the buns to deflate, ruining their lovely puffiness.
Cooling Time: Allow the pastries to cool completely before filling them with the chocolate pastry cream. This prevents the moisture from making them soggy, ensuring a delightful crunch.

Chocolate Choux Buns Recipe FAQs
How do I choose the right chocolate for the pastry cream?
Absolutely! When selecting chocolate for your pastry cream, it’s best to go for high-quality dark cooking chocolate with at least 60% cocoa content. This ensures a rich and intense chocolate flavor that will elevate your choux buns. If you’re a fan of milk chocolate, you can substitute it, but remember, the end result will be sweeter and less intense.
What’s the best way to store Chocolate Choux Buns?
For short-term storage, keep your chocolate choux buns in an airtight container at room temperature for up to 2 days. If you’ve filled them with pastry cream, refrigerate them for up to 3 days to maintain freshness. Don’t forget to cover them to prevent drying out!
Can I freeze Chocolate Choux Buns?
Yes, you can freeze unfilled chocolate choux buns for up to 2 months! Simply place them in a single layer on a baking sheet and freeze until firm. Then, transfer them to a freezer bag or airtight container to keep them fresh. When you’re ready to enjoy, reheat them in a preheated oven at 350°F (175°C) for about 10 minutes to restore their crispness.
What should I do if my choux pastry doesn’t puff up?
Very! If your choux pastry fails to puff up, it might be due to underscooking the dough or not enough moisture in the oven. Be sure to let the water, butter, and sugar mixture boil thoroughly before adding the flour. Furthermore, within the first 10-15 minutes of baking, avoid opening the oven door, as this can hinder the rise.
Are Chocolate Choux Buns suitable for those with allergies?
It’s important to note that chocolate choux buns contain common allergens like eggs and gluten (from the flour). For a gluten-free version, you can substitute regular flour with a gluten-free blend, but make sure it’s suitable for baking. Always check the chocolate packaging for potential allergens like nuts or dairy if you are accommodating special diets.
How long does the pastry cream stay good in the fridge?
Once made, your chocolate pastry cream can stay fresh in the refrigerator for up to 3 days. Be sure to store it in an airtight container to prevent it from absorbing any odors and to keep it smooth. If it thickens too much, simply whisk in a bit of milk before using it to bring back that velvety texture.
