Chocolate Cornet Recipe

✔ Updated October 18, 2026 · No-mold foil cones and custard fixes added

A chocolate cornet, also called a choco cornet or choco coronet, is a Japanese bakery favorite: a soft, spiral-shaped bread horn piped full of chocolate custard. I fell for that spiral shape before I ever tasted one.

This version uses an enriched dough made with bread flour, egg, butter and milk powder, wrapped around cone molds and baked golden, then filled with a cocoa and chocolate chip custard once cool. No cone molds? Homemade foil cones work just as well. The custard cooks and chills while the dough rises, so most of the time is hands-off.

Why You'll Love These Chocolate Cornets

• Soft, fluffy bread, an enriched dough with egg, butter and milk powder that bakes up tender.
• Thick chocolate custard, cocoa plus chocolate chips, firm enough to pipe and hold.
• No special molds needed, simple parchment-and-foil cones shape them just as well.

What Is a Chocolate Cornet?

A chocolate cornet, known in Japan as choco korone and often spelled choco cornet or choco coronet, is a classic of Japanese bakeries. It's a soft, slightly sweet bread twisted into a spiral horn and piped full of chocolate custard or chocolate cream. The name is usually traced to cornet, the French word for a horn or cone.

It's sometimes confused with a cream horn, but the two are quite different: a cream horn is made from flaky puff pastry and filled with whipped cream, while a cornet is a fluffy yeast bread with a thick custard filling. Fans even debate which end to eat first, the chocolate-filled wide end or the thin spiral tip (in our house, Max goes straight for the chocolate end), and the bread often shows up in anime and manga.

No Cone Molds? How to Make Foil Cones

Metal cream horn molds (sometimes sold as cornet or lady lock molds) give the neatest shape, but you can make perfectly good cones at home with parchment paper and heavy-duty foil. Make 10, one for each cornet.

• Roll the paper: roll a sheet of parchment paper, about 8 x 10 inches, into a tight cone about 5 inches long and 1½ inches across at the open end. Fold the loose edge inside to hold it.
• Wrap in foil: wrap a 10-inch square of heavy-duty foil tightly around the paper cone, smoothing it so the surface is even, and twist the pointed tip closed.
• Foil-only option: no parchment? Fold a 12-inch square of heavy-duty foil into a triangle, roll it into a cone and stuff it with a little crumpled foil so it doesn't collapse under the dough.
• Grease well: brush or spray the outside generously with butter or oil so the bread slides off.
• Remove while warm: twist the cones out about 5 minutes after baking, while the bread is still warm and flexible. Foil cones can be reused for the next batch.

Tips for Success

• Use lukewarm water for the yeast. Aim for 105 to 110°F, like a warm bath. Hotter water can kill the yeast; if it hasn't foamed after 10 minutes, start again with fresh yeast.
• Add the water gradually. Flours absorb differently, so hold back the last couple of tablespoons and add only what you need for a soft, slightly tacky dough that isn't sticky or wet.
• Rise somewhere warm and draft-free. An oven with just the light on works well; it’s where all my bread dough rises. The dough is ready when it has doubled and a floured finger poke springs back slowly.
• Roll long, even ropes. Start wrapping at the tip of the cone, overlap each turn by about a third and tuck the end underneath so the spiral doesn't unravel in the oven.
• Cook the custard fully, then cool everything. Let the custard bubble for a full minute so it sets, and fill only completely cooled cornets so it doesn't melt and run.

Chocolate Custard Troubleshooting

The filling is where most chocolate cornets go wrong. Here's how to fix the common problems.

Problem	Why it happens	How to fix it
Too runny	It wasn't cooked long enough for the starch to thicken. Egg yolks also contain an enzyme that thins custard if it isn't brought to a boil.	Return it to the pan and whisk over medium heat until it bubbles, then cook 1 minute more. Still loose? Stir 1 teaspoon cornstarch into 1 tablespoon cold milk, whisk it in and boil for 1 minute. It firms up more as it chills.
Lumpy	The starch was added straight to hot milk, or the pan wasn't whisked constantly and the bottom set or the yolks scrambled.	Whisk the cornstarch, flour and cocoa into the yolks and sugar first, then add the milk slowly. Push a lumpy custard through a fine-mesh sieve while it's still hot.
Skin on top	The surface dries out as it cools in the air.	Press plastic wrap directly onto the surface of the warm custard before chilling. If a skin forms anyway, whisk it smooth or lift it off.
Grainy or greasy	The chocolate overheated or the custard boiled hard after the butter and chips went in.	Add the butter and chocolate chips off the heat and stir gently until melted.
Too stiff to pipe	Chilled custard sets firm.	Whisk or beat it for 20 to 30 seconds until smooth and creamy before filling the piping bag.

Make-Ahead and Storage

• Custard: make it up to 3 days ahead and keep it covered in the fridge, with plastic wrap pressed on the surface.
• Baked bread: unfilled cornets keep in an airtight container at room temperature for 1 day, or frozen for up to 1 month. Refresh them in a 300°F oven for 3 to 4 minutes, then cool before filling.
• Filled cornets: keep them covered in the fridge and eat within 2 days. Don't leave them at room temperature for more than 2 hours, since the custard is made with eggs and milk.
• Overnight dough: you can slow the first rise in the fridge overnight; let the dough warm up for 30 to 45 minutes before shaping. See leaving bread dough to rise overnight for more.

Variations

• Vanilla custard cornets: leave out the cocoa and chocolate chips and increase the vanilla to 1 teaspoon.
• Chocolate whipped cream: fill with whipped cream sweetened with cocoa and powdered sugar for a lighter cornet. Fill just before serving.
• Matcha custard: swap the cocoa for 1 tablespoon of matcha powder and use white chocolate chips.
• Chocolate-dipped tips: dip the thin ends in melted chocolate and let them set before filling.

Frequently Asked Questions

What is a chocolate cornet?

A chocolate cornet, or choco cornet (choco coronet), is a Japanese bakery bread shaped like a spiral horn and filled with chocolate custard or cream. The soft, slightly sweet dough is wrapped around a cone mold before baking, and the filling is piped into the wide end once it cools.

How do I make chocolate cornets without cornet molds?

Make your own cones. Roll a sheet of parchment paper into a cone about 5 inches long and 1 1/2 inches wide at the open end, then wrap it tightly in heavy-duty foil and grease the outside well. Wrap the dough around it as usual and twist it out after baking.

What if I don't have a piping bag?

Use a zip-top bag. Fold the top of the bag outward over your hand so the edges stay clean, spoon in the custard, then twist the top closed and snip a small corner off with scissors. Push the tip into the open end of each cornet and squeeze gently until full.

What happens if the dough rises too long?

Over-risen dough can taste sour or overly yeasty, and it may collapse or bake up coarse and flat because the gluten has stretched too far. If it has more than doubled, gently punch it down, reshape it and give it a shorter second rise before shaping, watching it rather than the clock.

How do I store chocolate cornets?

Because of the custard, keep filled cornets covered in the fridge and eat them within 2 days. For the best texture, store the baked bread airtight at room temperature and the custard in the fridge for up to 3 days, then fill the cornets just before serving.
